A colder change roars in over the state today, and that is just one pattern change we are looking at. A shift in winds to the NW will bring temps down considerably from yesterday, and we end up slightly below normal. The second part of our weather pattern change is a strong storm complex that is exiting the central plains and moving east. The track is still south, and we even are going to push our precipitation threat a little farther south than our previous forecasts. So, putting the two things together, our forecast for today is for a mix of clouds and sun from I-70 north. Clouds will be in the increase in southern Indiana. Snow move in overnight from US 50 southward. We now expect a coating to 2 inches near US 50, and perhaps up to 3 or 4 inches in SW Indiana near Evansville. But that is it. We do not think the snow makes it all the way to even I-70. The rest of the state stays dry overnight. Partly sunny skies will be in over all areas through the day Saturday.
On Sunday we still have scattered snow showers quickly moving over the state. However, coverage is not as good, and we are dropping accumulations too. About half of the state (50%) can see a coating to an inch of snow on Sunday, but that is all. All snow chances are gone by the time we reach midnight Sunday night, and likely sooner. Dry Monday with a mix of clouds and sun, then net Tuesday sun will be followed quickly by clouds.
Rain develops overnight next Tuesday night from US 50 southward, and then moisture spreads north. We are looking for snow from I-70 north on Wednesday and still some additional rain south of I-70. Snow totals end up from a coating to 2 inches north of I-70, and rains will be .25” or less combined south of I-70. Precipitation coverage will be about 80% of the state. Behind that system, we put together two sunny, dry days for next Thursday and Friday.
Next weekend looks wet. Rains arrive for Saturday and bring .25”-1” with 100% coverage. The map above shows a snapshot of potential action at midday next Saturday. The rains go to snow for Sunday, and we can see some accumulations of 1-3 inches before everything exits to the east. The extended period starts with some sunshine and a milder afternoon for the 25th, before clouds increase on Tuesday the 26th. Moderate to heavy rains park over the top of us for Tuesday night through Wednesday the 27th, bringing half to 1.5” rains and coverage at100%. Moisture leaves before the coldest air arrives behind the system, so we should see precipitation stay all rain. Much colder to finish February on the 28th, and we keep partly sunny and cold conditions into the start of March on the 1st and 2nd.
