Wind, a Snowstorm, Frost, Heavy Rain all in the next 5 Days

Good Saturday bloggers,

We tracked scattered showers and thunderstorms earlier this morning, and now we are tracking a strong cold front with 40 mph wind gusts, an I-80 snowstorm, chance of frost/light freeze and the potential for very heavy rain. This is all in the next 5 days!

There is a Winter Storm Warning in effect from Chicago/Milwaukee to Waterloo today and tonight as 4″-10″ of snow is possible. The colder air up there will surge this way today leading to the chance of a frost/light freeze Sunday morning. Right now we are not in a Frost Advisory as there may be just enough wind to prevent that.


SATURDAY NOON: Look at the heavy snow in the Winter Storm Warning area. If you have travel plans along I-80 this weekend, keep this in mind as the snow will track into northern Ohio. Airport delays are likely as well.


SATURDAY NOON: We are a state away from the snow. We will be 70°-75° around noon with southwest winds gusting to 30-40 mph. Northwest winds gusting to 40-45 mph will be approaching from the northwest.


SATURDAY EVENING: Temperatures will be falling with north winds gusting to 40-45 mph. It will be in the 40s by 7 PM with wind chill values in the 20s and 30s. Bundle up if you are headed out this evening.


SUNDAY MORNING: Lows will be in the low to mid 30s. There may be some frost, but a 10-20 mph wind will prevent a widespread frost. Some locations may see a light freeze, but this should not be a problem for the newly planted vegetation. Sunday afternoon will be mostly cloudy with highs around 60°. A few showers and thunderstorms will be possible by evening.


RAINFALL FORECAST THROUGH WEDNESDAY: The cold front that comes through today will become a warm front Sunday and head north to around I-70. It will stall and waver through Wednesday as waves of energy at the upper levels track along the front. Heavy rain and thunderstorms will accompany each wave. The severe threat is low in our area, but something to monitor. It will depend on how warm it becomes and also the timing of the rain. Right now it looks likes the timing is later at night and early in morning. The main threat we have to watch for is flash flooding as 1″ to 4″ of rain is likely Sunday night through Wednesday. You can get 1″ to 2″ of rain in one hour with this set up.


SUNDAY NIGHT-MONDAY MORNING: The first wave of energy arrives. Heavy rain and thunderstorms are likely. We will have to watch for flash flooding.


MONDAY AFTERNOON: The front sags south, we go into the cooler air and the rain tapers to a few showers or even ends. Highs will be in the 50s, perhaps lower 60s if the sun pops out.


MONDAY NIGHT-TUESDAY: The front lifts back to the north as the next upper level wave of energy moves by. This will generate the next round of heavy rain and thunderstorms. Rain will linger Wednesday as one last system moves by. It looks drier Thursday into next weekend.


Have a great weekend.
