Labor Day Cold Front and Irma Update

Good Sunday bloggers,

The weather has been great for Labor Day weekend 2017 and it will continue today and Labor Day even as a cold front moves by Monday afternoon.  Irma is now a category 3, moving west at about 15 mph and about 1100 miles east of Puerto Rico.

We will go through the weather change the next two days and then have the latest on major hurricane Irma.

It was a beautiful Sunday sunrise with a few cirrus clouds and haze.  Have you noticed the haze?  It is mostly smoke from wildfires in Montana and points west.  You can tell it is smoke haze by the whitish color during the day.


SUNDAY: There is fog in northern Missouri and eastern Kansas this morning that will burn off after 10 am.  This will be a nice summer day and perfect for the pool as highs around KC climb to the 80s with highs 90°-100° to the west.


LABOR DAY: A decent cold front will move through during the afternoon.  This about 6-12 hours faster than we were thinking on Saturday.  Now, that being said, the cooler air is lagging behind the front, so highs will still climb to around 90° in KC with 100s in southern Kansas and northern Oklahoma.  If the front does slow down, then we will see highs 93°-96° in KC.  As it stands now, highs will range from the upper 80s in northern Missouri to low 90s from I-70 and south.  What about rain?  The front will be inactive as it moves by during the afternoon, so it still looks great for the pool.

MONDAY NIGHT: Scattered showers and thunderstorms will form on the front by evening, but the front will be approaching I-44, so our area will see some clouds as the cooler air moves in. There will be a lagging disturbance coming in from the north so we will see clouds increase Monday night and there may be a shower or thunderstorm.

EARLY TUESDAY: The disturbance from the north will be moving through, bringing clouds and a few showers and thunderstorms.  it does not look like much rain in our area, unless the front slows down.  So, all of a sudden it has been dry for a week and this is the one main rain chance the next 5-7 days.  So, we could use some rain after the wettest August ever.


TUESDAY MORNING: The clouds and any showers will quickly exit as temperatures drop to the 50s and low 60s.


TUESDAY AFTERNOON: This will be the first day of several days of spectacular September weather.  Highs will be in the 70s with sunshine, low humidity and a northwest breeze.  Lows will be in the 40s to low 50s Wednesday and Thursday.




Irma is now a category 3 as she churns west at 15 mph.


Irma is forecast to become a category 4 as she approaches Puerto Rico Wednesday-Thursday, and may become a category 5!  There are growing signs that she will turn northwest and either graze or miss Puerto Rico. It looks like the east coast is in the cross hairs of Irma between September 9th and 11th.  There is still considerable time to watch this dangerous storm.


This is the 6Z GFS model valid September 11th.  It has Irma pounding the Carolinas with a pressure of 890 mb or 26.28″ just before landfall! That would be insane and let’s hope that is wrong.  Again, this is far from set in stone and we will be updating this daily.


Have a great and safe rest of your Labor Day weekend.  Remember DON’T DRINK AND DRIVE!
