Current Weather Conditions
Some areas around Chicagoland may see isolated showers or stronger cells with hail in the late night and overnight hours, but the greater threat of severe weather and the potential for tornado development has diminished.
Expect temperatures to tumble overnight, bottoming out in the upper 40s around sunrise Saturday.
While Friday was unseasonably warm, the day’s cloud cover appears to have increased stability in the atmosphere, reducing the threat of severe weather.
“If we do see more sunshine when we have these warmer temperatures and humid conditions, that typically creates a more unstable atmosphere and fuels that potential for thunderstorm activity a little bit more,” WGN meteorologist Alyssa Donovan said Friday evening. “So, better news for us that we didn’t see much sunshine today.”
SATURDAY: A markedly cooler day ahead with afternoon highs as much as 30 degrees cooler than Friday in some areas. A good deal of cloudiness, a stray shower possible early in the morning. Some brief glimpses of sun are possible in the afternoon. Temperatures settle back into the middle 40s near the lake PM as north winds become northeast 5-10 mph. High: 57.

Looking Ahead
Extensive cloud cover will continue to dominate the weather scene across the Chicago area on this Easter/Passover weekend with the next weather system bringing scattered showers by Sunday afternoon, continuing at times into the first half of Monday. A few thunderstorms will also be possible Sunday night into Monday morning.
Temperatures will be noticeably cooler as well. There’ll be no repeat of the near 80 degree warmth on Friday. Instead, highs both Saturday and Sunday will only reach the 50s, a level some 20+ degrees cooler. For areas close to Lake Michigan, it will be even chillier. Highs may struggle to make it out of the 40s on Easter Sunday.
Heavy rain will be centered along a frontal boundary from Oklahoma City to St. Louis with a slight risk of severe weather across the southern Plains into portions of the Ohio Valley.
A swath of very heavy rain from northern Texas into the St. Louis area where 3-5” totals are likely. This has prompted the issuance of a Flash Flood Watch for that region.
Rocky Mountain heavy snowfall continues where 6”+ is possible in higher elevations of Colorado.
