* Wind chill advisory 1 a.m. to 10 a.m. overnight into Tuesday morning *
7 a.m. update: Temperatures have already reached the mid-30s to around 40 in the metro region, and could pop into the 40s this morning before the cold front passes midday.
FORECAST IN DETAIL
The fourth fierce blast of arctic air this month crashes into the region by tonight unleashing yet another dose of subzero wind chills into Tuesday. The cold hardly relents Wednesday when a storm passes to our southeast. We’re probably too far away for serious snow, but it’s worth watching. We’re back into the 30s by Thursday and Friday. The weekend, however, could be unsettled.
Today (Monday): Thanks to a little boost from southerly winds, temperatures warm well into the 30s through midday. But then the arctic front blitzes the region, bringing a chance of snow flurries and then increasing winds. Early afternoon highs range from the mid-30s to near 40. But after mid-afternoon, temperatures start to fall back towards freezing. Winds from the southwest in the morning at 10-15 mph, increase to 15-25 mph in the afternoon out of the northwest, with some gusts to 30 mph. Confidence: Medium-High
Tonight: A brutally cold night. Evening temperatures drop through the 20s with wind chills free-falling through the teens. Overnight lows range from the low single digits in the colder suburbs to around 10 downtown. Winds from the northwest at 10-20 mph, produce wind chills from -5 to -10 early Tuesday morning. Confidence: Medium-High

Tomorrow (Tuesday): Extremely cold to start the day, with many locations in the single digits with subzero wind chills. Despite considerable sunshine, highs only manage the mid-to-high teens (in the colder suburbs) to the low 20s downtown. Winds are from the northwest around 10-15, but relaxing in the afternoon. Confidence: Medium-High
Tomorrow night: Some increasing high clouds, calm and – of course – very cold. Lows range from 12 downtown to the low single digits in the colder suburbs. Light winds. Confidence: Medium-High
A LOOK AHEAD
On Wednesday, there’s 20-30 percent chance of light snow (highest chances to our southeast). However, odds are the weather system remains far enough away that the metro region and points north and west stay dry. Irrespective of whether we see snow, we’ll probably see the storm’s bank of clouds, with highs 20-25. Partly cloudy and cold overnight with lows in the mid-to-high single digits in the colder suburbs to mid-teens downtown.Confidence: Low-Medium
Partly cloudy and not quite as cold Thursday into Friday, with highs 30-35 Thursday, lows 15-23 Thursday night, and highs 33-38 Friday. By late Friday, we’ll need to monitor some moisture streaming into the region from the west and southwest, but most precipitation probably holds off til early Saturday. Confidence: Medium
The weekend looks unsettled but the specifics are really tough to pin down. A front will be in the region, meaning the chance of some precipitation. Depending on what side of front we end up on, we could have snow, mixed precipitation and/or rain. It’s also difficult to say exactly when precipitation may start and stop. Highs both days are in the 30s to near 40, with overnight lows generally around 30. Confidence: Low-Medium
