FORECAST IN DETAIL

Unless you’re a fan of November and December-like chill, today’s the week’s finest day weatherwise. We introduce the chance of showers Tuesday as a big cold front approaches the region.  Fall’s coldest air, thus far, rolls in Wednesday and we remain unseasonably chilly, though mostly dry, through the weekend.

nice dayToday (Monday): A few folks in outlying areas to the north and west may awaken to some patchy frost.  Irrespective of where you are, wear an extra warm layer when you get up and head out, with temperatures in the 30s and 40s.  You’ll be able to shed it later, as temperatures warm to near 60 by noon, with a few spots getting close to the 70-degree mark by late in the afternoon.  Winds are light, becoming southerly at 5-10 mph in the afternoon. Confidence: Medium-HIgh

Tonight: Clouds gradually increase and not as cold.  Lows in the colder suburbs still dip into the low-to-mid 40s with near 50 downtown.  Light winds. Confidence: Medium-High

Tomorrow (Tuesday): A mostly cloudy day, with the best chance of intervals of partial sunshine in the morning.  During the afternoon, there’s a 30 percent chance of showers ahead of the inbound cold front, with highs in the mid-60s. Winds are mostly from the southwest, at around 10 mph. Confidence: Medium

Tomorrow night: As low pressure develops along the front moving through, we may see a period of rain showers (40-50 percent chance), mainly before midnight.   Lows range from 45-50 (suburbs-city). Confidence: Medium

A LOOK AHEAD

Unsettled and blustery Wednesday, with a 40 percent chance of showers.  High temperatures are in the chilly side, in the mid-to-upper 50s.  You should notice the winds whipping up in the afternoon, out of the northwest at 10-20 mph, with some higher gusts.  Partly cloudy, breezy, and quite chilly Wednesday night. Lows range from 34-39.  For the first time this season, I have to bring up wind chills, which will dip into the upper 20s and low 30s. Confidence: Medium

Thursday and Friday are both variably cloudy and unseasonably chilly.  Highs both days range from 48-53 with overnight lows 27-35 (suburbs-city).  On Thursday afternoon, a sprinkle  (or snow flurry in some of the high spots to the west)  is possible.  Early Friday morning, I expect to see some frost advisories and freeze warnings. Confidence: Medium

The weekend remains much cooler than normal, with perhaps a modest moderation in temperatures Sunday.  Highs Saturday are in the low 50s with perhaps mid-50s Sunday.  Lows Saturday and Sunday morning are in the upper 20s to mid-30s (suburbs-city), meaning more freeze and frost concerns. Confidence: Medium
