Good Sunday bloggers,
Today is the Winter Solstice.
So, are we going to have any winter weather for Santa? Well, it depends on a two part storm system for this week. Lets go through the weather today into Christmas eve.
TODAY 3 PM:
It will be cloudy with areas of mist and temperatures 40° to 45°.
Tonight we begin to feel the affects of part #1 of the storm system.
THIS EVENING AND OVERNIGHT:
Periods of drizzle will be likely with temperatures staying in the low 40s, so no ice/snow will occur.
The main part of part #1 of the storm system moves by with rain showers. Rainfall amounts will be trace-.20″. Rain will be falling all the way to Omaha and Des Moines, so no icing if you have plans to travel north on I-29 or I-35.
Part #1 of the system moves away. There will be a light mix to rain in Chicago, so if you have plans to head up there, it does not look like a big deal, perhaps some small delays. Here in KC it will come close to 50° behind the rain and ahead of a cold front. This is not a strong cold front. It will drop us to where we should be for this time of year, highs in the 30s.
Now to part #2 of the storm system. This part will track southeast through the Rockies into the southern Plains on Tuesday. Tuesday afternoon will see a small area of mixed precipitation form in north Texas. Our area will be cloudy, breezy and cold with a few flurries.
The second part of the storm system intensifies rapidly as it heads northeast into the Ohio Valley and Midwest. It will stay well east of our area. We will just see clouds, flurries and a northwest breeze at 10-25 mph with highs in the 30s. So, it will not be a White Christmas, but we may see a few snow flakes to add atmosphere. The east coast will have rain and wind with some severe thunderstorms in the deep southeast USA. A band of snow will occur from St. Louis to Chicago to Detroit east. So, these cities are on the western edge. It does not look as strong as it did Saturday and it will track further east. So, there will be travel impacts, air and ground on Christmas Eve, mostly east of the Mississippi river.
Have a great day and happy holidays.

Good Saturday bloggers,
It has been days since we have seen the sun. Well, today the sun will shine down upon us as a clearing line approaches from the west as I write this. This will be an active few days of weather as a strong storm system forms in the middle of the USA early Christmas week. It is going to come close to KC. So, lets go through the next few days as this storm will impact travel.
SATELLITE PIC EARLY SATURDAY: The clearing line will move through, but later today the clouds from the south will move back in. Highs will rise to the low 40s with the sun.
SUNDAY 3 PM: The clouds are back with some mist as highs warm to the mid to upper 40s.
MONDAY 7 AM: Part #1 of the strong storm moves through with a band of rain showers. We could see a trace to .15″. Temperatures will be in the 40s.
MONDAY 3 PM: After part #1 moves by we will see southwest wind and some sun. This will take our temperatures to near 50°.
Then, colder air will rush in Monday night as part #2 of the storm forms in the southern Plains. This will become the main part of the storm system for early next week. As it stands now, it will track up I-44 bringing rain, snow and wind from Springfield to St. Louis. We will have to watch for it to form a bit further west. In that case then KC could be impacted. Even if the storm does track along I-44 we could see some snow showers and flurries.
TUESDAY NIGHT AT MIDNIGHT:
CHRISTMAS EVE: The storm really intensifies and becomes a full blown snowstorm across northern Illinois and Wisconsin. So, if you have travel plans to Milwaukee or Chicago airport delays are quite likely. The east coast will have rain and wind and likely airport delays as well.
Have a great week and happy holidays

Good Thursday bloggers,
The snow is about over and amounts played out just about as forecasted. The heavier band along I-35 was about 10 miles west of where Gary had the band last night. But, our 1″-3″ forecast turned out well.
Wider view of radar estimated snow totals.
This is just a radar estimate. So, we would love to have your snow totals as nothing beats the human touch.
The rest of today will be cloudy with flurries and some mist as temperatures rise to 32-34. There will be a chance of re-freezing tonight and some black ice, so be aware of that.
Gary will have more later.
Have a great day and enjoy the snow. It is good snowman snow.

2 AM Update:
Good morning bloggers,
An extremely heavy snow band tracked across Olathe to Downtown. This clipped the Plaza and an inch of snow fell and the snowflake contest ended around 2:30 AM. 4″ fell in Merriam, YES FOUR inches of snow from that band fell in parts of the KC Metro area, while others were less than an inch. New areas of snow are increasing to the west, so most areas will end up in that 1 to 4 inch forecast range. There has been some graupel (snow pellets) that cut into totals in areas that did not get the heavy snow band. Let us know how much you end up with when you wake up.

Good late evening bloggers,
As Tom Petty sang, “The Waiting Is The Hardest Part”. I think that is how it goes. If you stare at radar it can drive you nuts. At 9:40 PM the radar echoes began rapidly increasing, so hang on. Remember we aren’t forecasting a major snowstorm here. Widespread 1 to 3 inch amounts are what we are forecasting. There may be a couple of pockets with more than that. Here is the map I am showing at 10 PM:
So, try to be patient. There is no way this one goes “poof”. Now it may around 6 or 7 AM, but not for the next seven hours. It is coming and 1 to 3 inches will fall. Let us know when you see your first snowflakes. Have a great night. I will check in later.

Good evening bloggers,
We are currently on the air right now and updating this forecast on the fly. The latest data has a low end total of around 1″ and higher end amounts of 4″ or higher. On our analysis we are attempting to pick out the likely areas the will end up with 2″ of snow or more as you can see below:
The snow is now developing southwest of Emporia and it marching it’s way northeast up I-35. This storm, if it starts earlier, has a better chance at some of the higher totals. Let us know what you think, and let us know when you see your first snowflakes! Have a great evening. The snowflake contest is about to end.

Good Wednesday bloggers,
The new data is in and snow is an almost 100% certainty tonight as a storm system tracks in from the southwest USA. It looks like the storm will hold together and be strong enough for bands of heavier snow. This is still a storm falling apart as it moves towards us, but it looks like it will wait until after it passes KC and our area to do so. We are in a Winter Weather Advisory from 6 PM today to 9 AM Thursday.
I will time this out and go over the new data today at 11 AM on 41 Action News Midday. Gary will have a more detailed blog later and have new data and updates on the NOW KC at 4 PM and and 5, 6 and 10.

Have a great day and enjoy the snow!

Good evening bloggers,
Look at this! Our local ski area Snow Creek is making snow. Now, will we get snow to fall from the ski? Yes, but how much?
I am currently getting ready for the newscasts on 41 Action News, and the NAM model just came out with a “BIG” warning sign for those of you hoping and wishing for snow. This also happened with the storm in November. This is the first model run that has not had a more amplified wave as it is approaching the area on Thursday morning, and instead it has a flat wave. It doesn’t mean that this will be the final solution, and even with this solution there could be a thin band of 3″+ of snow. But, my confidence just took a shot as I am analyzing this data. Take a look:
This is the first run that does not have an organized vort max, and instead, as seen in the yellow color, there is a stretched vorticity pattern, that gets even more stressed by Thursday morning. In the past few model runs I was rather impressed with how the wave was looking and I, as a snow enthusiast, was hoping that the wave would look even stronger, and not weaker. Unfortunately, for us snow lovers, this is not a good thing to look at. It doesn’t mean it won’t snow, and this may still be quite wrong, and even this solution has a band of 2 to 4 inch snow potential north and west of Kansas City, so I am still holding out hope that it looks a bit better on the next few model runs.
We will be in the left front quadrant of this system, which will provide just enough lifting for it to snow Wednesday night and Thursday. If there is just a bit more organization than is shown on this latest model run, then we can get the higher amounts. It is a concern as I am currently working on the forecast. This is just one model, but it is this NAM model that actually predicted much less snow in the November 15th system that left us with barely a dusting. It is something to think about.
One thing in the favor of slightly higher amounts is the fact that I believe we can see the disturbance that is coming this way. Take a look:
Take a look a the rain around San Diego. That rain and band of clouds with a little curl to it is heading our way, and this is the disturbance we will have to watch closely.
Have a great late afternoon or evening, and I will be covering this tonight on 41 Action News.

Good afternoon bloggers,
A storm system is spinning overhead this afternoon with the rain and snow shifting away to the north as this storm moves out. Take a look at the interesting temperature pattern around this tightly spinning system as of 1:30 PM:
It was 51 degrees in Des Moines, 54 in Columbia, and 43 to our south in Chanute, KS. The colder air is wrapping in behind this storm from the west and southwest. Now, here I come back from a week off and I am dealt with a pretty big forecast problem for Wednesday night into Friday. Will we see precipitation? Right now I am confident we will, so I am going to up the probabilities significantly. What type will it be? Snow, Rain, Freezing rain? It will not be a big event, but our latest Powercast has over an inch of snow in KC Wednesday night. Take a look at this:
Let me stress that even though I am leaning heavily in the “it will precipitate” trend, this is a rather light precipitation event, and that makes it even more difficult to forecast……once again! We will discuss these things on 41 Action News. I will show this powercast in motion. Let us know what you think? And, then if you are wondering about Christmas week, and I talked about it on Weather2020, but a cold outbreak is likely increasing the chance of snow, as we have had in our forecast for weeks now based on the LRC.
Let the fun begin!

Of course, our late newscast is at the mercy of Sunday Night Football, so here is a quick update on what’s going on.
The main band of rain continues to push through the area.
The top the hour rainfall observations are nice in a few areas.
I still think we’ll see rain for the next three to four hours before it starts to taper off. I am going to stick with my previous forecast and say that the back edge will pass through Monday afternoon and produce a few more light showers.
That said, some of the new information I’ve seen roll out is suggesting a few snow flurries may try to make an appearance in Eastern Kansas after 8 to 9pm Monday. This will not accumulate or amounts to anything, but if someone in Lawrence told me they saw a snowflake Monday night, I would not be surprised.
I’ll have a fresh forecast for you after the game is over tonight. Of course, Kalee will be in bright and early tomorrow morning with another fresh take on things.
Right on cue, the rain is moving into the area tonight. I expect it to be in the greater Metro around 7p, and then inside the 435 loop around 8:30p. Here is the wide look map:
And this is it on closer inspection:
This main rain band should push through and be gone a little after midnight tonight. Some lingering sprinkles and showers are possible. Earlier today, thunderstorms produced hail and a few tornado warnings in parts of Oklahoma and Southern Kansas. I do not see that kind of activity for us.
Latest look at the high-resolution HRRR model shows the radar looking like this around 10pm tonight:
The model may be hitting the heavy rain a little hard, but I do believe there will be pockets of heavy downpours. Plus, a few rumbles of thunder are still possible.
Oddly enough, I had several questions about us getting thundersnow tonight. I do not see that! It’s going to be far too warm at the surface to produce snow. Our temps will be in the 50s all night.
Here is the rain timeline for tonight into tomorrow:
For Monday, as this system continues to truck East, we’ll see a second window for rain as the back edge slides through. I would expect this somewhere between the Noon and 4pm timeframe. Just a few showers is all it should be.
By Tuesday, the cold air returns and brings some strong Northwest winds with it. Sustained winds around 25-30mph would not surprise me. Add in air temps in the mid 30s, it’s going to feel pretty raw. So while you may have ditched the jacket today, you’ll need it and the coat by Tuesday!
All right, what about those snow chances later in the week? Models continue to agree that there is a chance. Right now, here is how I see things:
That last line is key: we have to wait and see how that storm may track. Should it dip farther South, we won’t get much of anything here. Should it take a bit more of a Northerly track, things change.
Without publishing a snowfall map (which would then get shared and passed around as “truth”), let me say this: as of this moment, right now the Euro model calls for nothing more than 1-3″ across the entire area. The GFS parallel says 1-2″. The operational GFS is hinting at 2-4″.
So what I see from this, as it stands now: not a “major” storm. That said, KC has yet to see an inch of snow this season. Thus, it could become a big deal should a few inches fall.
The best advice I have: please do not get your heart set on a number just yet. Whether you love snow or loathe it, don’t set yourself up for something that still may not happen.
As I tend to do on Sundays now, let me show you my forecast worksheet for the coming week, comparing the models with what I am forecasting.
And, for verification, here is the result from last week.
Here again, it was the Euro that was the closest down the stretch. I’ll freely admit, I did not do as well as I would have liked. The low, gray clouds really messed things up. But that’s the way it goes. As you can see, pretty much everyone missed Wednesday.
I will be off next weekend on my first vacation in a long time. Some have asked if/when I’ll ever get time off! I know you just want me off your TVs for a while!
All the best this week and here’s to hoping whatever weather you want, happens outside your door this week.

Overall, the forecast seems to be on track for the second half of the weekend. Clouds to dominate the sky most of Sunday but I am still seeing signs that we’ll get sunshine to work its way into the Southeast part of the viewing area late in the afternoon.
That will not last long, however. The rain system we’ve been tracking will start to push into the area by 7pm.
For those going to the Chiefs game, I don’t think you have to worry about rain. Plus, it will be fairly mild for mid December (our average high is 40° in KC).
Timing out the rain chances for Sunday, it looks like this to me.
For Monday, as the system passes by, we should find ourselves in the dry slot of the storm. However, as the system pulls away, I could see some wrap-around moisture impacting the area Monday afternoon. Along with that, we’ll start to draw in some colder air. This means falling temperatures on Monday.
No snow expected for us this weekend. But I know some of you have been following the models and watching them try to sort out the snow chances for next week. While the finer details are still rough around the edges, stepping back you can see there is agreement that snow will fall in the area. Now does that mean it’s a 100% chance right now? No, not at all.
From what I have seen on the 12z runs of everything, all models suggesting a little accumulation of snow on Thursday, a little more on Friday, and then perhaps one last little bit for Saturday morning.
Right now, the totals from the Euro model indicate around 2-4″ for the greater viewing area. The GFS parallel suggests amounts around 1-3″ for the greater area. Again, these are just model suggestions not our forecast. There is still a lot that can (and will change).
One thing that caught my attention this afternoon, was a comparison of all the major models and their ensembles. What the heck is an ensemble? Each main model (GFS, Euro, Canadian) has one. What happens here is that some of the initial data used to run the model is altered slightly to see what outcome it produces. For example, maybe the operational run uses an air temperature of 50° and a dew point of 45°. It then spits out a solution. The ensemble, however, may use an air temperature of 55° and a dew point of 40° and comes up with either a completely different solution or, perhaps a very similar solution to the operational GFS.
Here is a comparison of operational models (on top) with their ensembles on the bottom and this is for 6p Thursday. Click to enlarge.
One thing I notice here, simply looking at the big white line (the freezing line), four of the five keep that freezing line along or North of I-70. Only the operational GFS pushes that cold air farther South.
Jumping ahead 24 hours, look at the difference.
In this setup, the operational Euro and GFS push that cold air South, but their respective ensemble counterparts are not as aggressive. What all of this tells me is: we’ll see a lot more flip-flopping of the models over the next few days.
It’s too early to try and dig through the details of the models and hash out a forecast for snowfall that’s going to be reliable. It’s all just going to change tomorrow anyway. So, let’s not try to pick out a single tree in the forest. Let’s just call it a chance for snow next week and leave it at that until we get closer to the event. Wishcasting does nobody any good and I refuse to post a snowfall map this far out. That’s what leads to hype and eventually to people saying “you said xx inches of snow and I only got xx inches. Must be nice to be wrong all the time and still keep your job!”.
For those wondering about temperatures this month, it’s actually been a fairly balanced December so far. Almost 14 days in and we’ve had seven days above 40° (which is the average high) and six days below.
After Monday, it may be a while before we see temps above 40° again this month. Especially if we do wind up with snow next week. We’ll continue to provide updates on it all.
