FORECAST IN DETAIL

Springlike, muggy conditions today change quickly late tonight, back into something more familiar — that winter feeling. It’s back tomorrow, and into next week. Daytime peak temperatures in the 30s may be on repeat. We’re watching next week for wintry precipitation chances, too.

Today (Friday): We could have scattered showers around any time, but the highest chances for  rain (and a bit of fog perhaps) are during the morning hours. High temperatures may take advantage of any afternoon lulls in precipitation, and moderate southerly winds around 10 mph, to attain mid- to upper 60s. Even with a nearly overcast sky! Confidence: Medium-High

Tonight: Clouds hang tough. Rain chances increase again by late evening. By the middle of the night and into the early morning hours, rain intensity could pick up as well. Our season-resetting Arctic front could even spawn an isolated rumble of thunder. South-southwest winds gust above 15 mph overnight, before predawn winds come in from the northwesterly direction. These cold, dry winds could gust near sunrise above 20 mph. Temperatures could drop to around 40 by sunrise (even 30s in our colder areas), about 20 degrees colder than at dinnertime. Confidence: Medium

Tomorrow (Saturday): You’ll notice how quickly winter has returned as the sun rises. Gusty northwesterly winds may average in the 15- to 20-mph threshold, so do bundle up since wind chills could dip back toward 20 degrees or so. Even as skies slowly clear, temperatures continue to fall from around 40 in the morning to perhaps 30 degrees as the sun sets. Confidence: Medium

Tomorrow night: Mostly clear skies, but still somewhat blustery with moderate northwesterly winds. Downtown could bottom out from 15 to 20, and about 10 to 15 degrees in the suburbs. Wind chills hover in the single digits by the early morning hours, so please use caution if outside late into the night. Confidence: Medium

A LOOK AHEAD

Sunday: Mainly sunny skies is the good news, but unfortunately, northwesterly winds may remain persistent around 10 mph. This could keep wind chills roughly 10 degrees below high temperatures in the mid-20s to around 30. Confidence: Medium-High

Sunday night: Cold, under partly cloudy skies. Luckily the northerly breezes keep diminishing, but they still take a few degrees off the temperatures to chill us further. Low temperatures get raw enough before dawn — in the low to mid-teens. Confidence: Medium-High

We could stay in the chilly 30s for high temperatures both Martin Luther King Jr. Day and into Tuesday. Both days could have some sun, but our holiday could have brighter skies than Tuesday. It’s unclear whether  some precipitation moves into our region for Tuesday. If it does, we could see some snowflakes. It could mix with rain. Nothing too heavy, as it appears now. Even though we can’t yet pin down the exact timing and type of precipitation, we’ll watch it for you. We could have a cold ground, once again, by Tuesday. Check back late this weekend; we hope to eliminate a couple of question marks. Confidence: Low-Medium

2/10 (→): We’ll keep an eye on Tuesday and Wednesday, when flakes could accumulate thanks to cold air sticking around.
