FORECAST IN DETAIL


Again this winter’s trend of cold or precipitation, but not together, rears its (ugly?) head this week. Today brings the cold and gusty winds, but not much more than a few flurries or snow showers. We warm up a bit just in time for our next round of precipitation, which may start briefly as a wintry mix on Tuesday morning but should end up mostly rain. Then we dry out by Wednesday as winter’s chill returns.

Today (Sunday): As a coastal storm heads up into the Canadian Maritimes, we’ll feel a biting chill on the back side of it. Those winds crank up from the northwest early in the day, sustained near 20-25 mph with gusts around 35-40 mph. We’ll keep a 30% chance for some flurries or snow showers under partly cloudy skies. But more importantly, the winds coupled with highs struggling to the mid-30s at best, maybe only low 30s, put wind chills in the mid-teens to low 20s. Confidence: Medium-High

Tonight: Skies clear and winds slacken, but breezes still stay up around 15 mph for much of the night with some higher gusts. The breeze keeps temperatures from tanking as far as they could, but expect a chilly night regardless with lows in the mid-teens to low 20s. Confidence: High

Tomorrow (Presidents’ Day): High pressure works into the area for our holiday, leading to a nice, mostly sunny day. Despite the sun, we’re still on the cool side, though without the biting winds it feels a whole lot better than today. Highs reach near 40 to the mid-40s. Confidence: High

Tomorrow night: Evening skies should stay mostly clear but clouds increase overnight as the next weather-maker heads our way. Western suburbs could see a light wintry mix toward morning as overnight lows dip to near 30 to the low 30s. Confidence: Medium

A LOOK AHEAD

A cold front works its way through on Tuesday. That means rain showers are likely during the morning into midday. Some snow, sleet and/or freezing rain may briefly mix in early in the morning. But warmer breezes from the south should fairly quickly change precipitation to all rain before any major wintry impact. Highs climb to the mid-40s to low 50s. Skies start to clear by evening and colder air filters in overnight with lows in the mid-20s to low 30s. Confidence: Medium

Wednesday brings more cold and blustery conditions with a chance of flurries. Even with some sun, chilly winds from the west/northwest keep us shivering as highs struggle to near 40. Confidence: Medium
