Snow continues to fall in northern Illinois & southern Wisconsin to southern Michigan.
This is a webcam from Chicago just west of O'Hare Airport.
Temperatures are 40-51 over our viewing area now after highs today 42-57.
One main round of rainfall has passed with some isolated thunder. Rainfall totals range from a trace to 0.30" as of 6:30 p.m.
Warm front is laid up southwest of our area, re-enforced southwestward by rain-cooled air in our area.
Clouds are eroding south of the warm front. Also note the building cumulus towers then along the cold front west of here as some t'storms try to develop.
Between the warm front & cold front near the surface low, temperatures are as high as the lower 80s in eastern Missouri & 75-80 in western Illinois. It is even 75 in far northeastern Missouri.
The 60s are now moving into parts of central Illinois.
Center of storm system will pass near our area with warm front potentially getting to I-74 this evening. Temperatures may rise in our southern areas ahead of the showers & a few isolated t'storms (see below). Temperatures will then fall once the cold front moves through.
Another wave of showers & even a few isolated t'storms should form to our west & move eastward, passing as round #2 of rainfall the evening-tonight.
Any MARGINAL RISK of severe weather looks to stay southwest of our area, however.
Rain may end as brief flakes north of US 24 tonight, followed by clearing & lows 31-37 (36 Greater Lafayette).
It will turn windy tonight with those cold temperatures. North winds may gust to 38 mph at times, dropping wind chills to 22-29 late.
Sunday will turn brighter, but it will be breezy & cool with highs 55-60 (57 Greater Lafayette).
Warm front will move back northward Sunday night with a couple rounds of showers & a few t'storms along & north of it Monday morning.
Rainfall should taper Monday afternoon.
At this point, it looks like any severe risk will stay west & southwest of our area.
The warm front will split the area in half in the afternoon with 70s south, mid 60s Greater Lafayette & 50s north. Even Monday night-Tuesday morning lows will range from 41 in the far north to 62 in the south & around 54 in Greater Lafayette.
Showers & some t'storms will develop late Monday night & last into Tuesday morning. Some additional development will occur Tuesday afternoon-evening.
The best rainfall coverage looks to set up over the northern half of the viewing area.
A couple severe storms are possible near the warm front.
It looks like a situation of 50s in the north with up to 80 in the south with mid 60s at Greater Lafayette. However, it may end up being like 64 at Battle Ground & 72 along Veteran's Memorial & 76 at Stockwell.
It is a very tough, tedious call, but certainly our southern counties have a much higher probability of getting quite warm & humid, while the north is cool & quite rainy.
Warm front may move completely north of the area Tuesday night to Wednesday morning. Temperatures may run 65-72 Tuesday night with a strong southerly wind.
Showers & storms are possible, along with some severe risk.
After highs 68-77 Wednesday, it appears that front will drop southward with a round of showers & t'storms & perhaps some severe weather risk.
Area may be split by front Thursday with 59 northwest & 80 southeast.
Showers & t'storms are possible Thursday. An isolated severe t'storm is possible.
Including today, 2-4" of rainfall is likely by Thursday night for the viewing area.
Front will then sink south of the area & we should dry out Friday.
Front will begin to migrate back northward again next weekend.
Winds will be strong from the south Sunday-Monday after being light from the northeast, east, then southeast Saturday.
Showers & t'storms should return late Monday after highs of 77-81.
