3:30 p.m.: The National Weather Service has issued a severe thunderstorm warning until 4:00 p.m. for the far southern suburbs. Hail up to quarter size and strong winds are possible with this storminess. Additional activity is somewhat sparse, so the rest of the afternoon may be quieter.
2:20 p.m: Temperatures that hit the 50s have been knocked back into the 40s, and even upper 30s in spots well to the northwest, thanks to multiple rounds of showers. Additional rises this afternoon may be minimal.
12:15 p.m.: Some of the most intense showers today may contain small hail and a rumble of thunder.EXPRESS FORECAST

Days and days of highs 50 or below (as Jason noted yesterday) feel decent -- in February, when they are common. A change to warmer can’t come quick enough for many, but we’re on a slow crawl through the weekend. Today’s cool showery demeanor is followed by a more palatable Sunday that brings another risk of raindrops late. A strong Midwest storm sends a brief shot of much warmer air in to start the work week… And maybe the risk of t’storms?
Today (Saturday): Good news... We warm up a bit. Bad news... An active jet stream still remains to our south, keeping cool and unstable air overhead. Like yesterday, clouds rule. The best odds for some breaks are early in the morning and again late in the day. Into the midday and afternoon, some scattered showers, and maybe a rumble, are a good bet. Highs range from the low-to-mid 50s -- still too far below average for my liking. Breezes from the northwest continue, with gusts to about 25 mph. Confidence: Medium-High
Tonight: At the very least, clouds should thin and become fewer into the overnight, coincident with daytime breezes diminishing. We may even end up going mostly clear by midnight and headed into morning. Lows dip down to the chilly mid-30s to near 40. Confidence: Medium-High

Tomorrow (Sunday): Cherry Blossom Ten Miler temps (7:40 a.m.) are around 40, rising to the upper 40s by 11 a.m. Morning is the best bet for partly to mostly sunny skies, but a warm front quickly advancing from the west wants to bring in clouds before dark. Clouds probably increase fairly quickly during the afternoon or evening, and showers are possible around sunset. Highs should range from the mid-50s to near 60 -- accounting mainly for cloud cover, if there isn’t much, most of the area could near 60. Confidence: Medium-High
Tomorrow night: Showers remain possible through the night, but I don’t think they’ll be widespread and it’s possible they could slip to the northwest and north entirely. Clouds are widespread though. A fresh breeze from the south, following the warm front passage, keeps temperatures from falling below the low-to-mid 40s. Confidence: MediumA LOOK AHEAD
With a powerful storm headed through the Great Lakes toward Canada, high pressure off the Southeast coast and at least partly sunny skies, Monday looks like a bit of payback for the last week-plus of cold weather. Temperatures well into the mid-and-upper 70s seem a good bet if we see enough sun. We’ll need to watch for a line of powerful thunderstorms headed east toward the Appalachians late in the day. Confidence: Medium
The cold front works toward the area Monday night into Tuesday. Everything has sped up a bit, so Tuesday may end up cooler than previously thought. There’s a chance of showers and thunderstorms (some could be severe thanks to strong winds aloft) in the morning through the first half of the day. Numerous clouds, rain, and cooler air behind the front may keep daytime temperatures (highs near midnight?) in the 50s. Any shift earlier makes cool temperatures more likely, while a return to an afternoon frontal passage could send readings well into the 60s. Strong gusty winds are also likely behind the front as temporarily chillier air comes rushing in. Confidence:Medium
