FORECAST IN DETAIL


Whatever you did yesterday to battle the cold, you’ll want to do it again today. We’ll see a bit less wind today, but wind chills are still stuck in the brutal teens. Sure, it’s not unusual for the area to have a couple days as cold as these in a typical winter, but that doesn’t make it feel any better, right? Temperatures warm only slightly tomorrow and Friday. And to make things even more wintry we have two opportunities for snow - tonight and Friday. Neither looks terribly impressive, but light accumulations are possible.

Today (Wednesday): Day 2 of this arctic blast is much the same as yesterday. Morning lows start in the upper single digits to mid-teens under mostly sunny skies, and only reach the mid-to-upper 20s for afternoon highs as clouds increase. The only saving grace is less wind than yesterday, but a breeze from the west at 10-15 mph should still be enough to keep wind chills from escaping the teens. Confidence: High

Tonight: A quick-moving upper-level system could produce flurries, snow showers, or even a period of light snow between approximately 10 p.m. and 6 a.m. A dusting to 1 inch or so is possible if any heavier snow showers or steady area of light snow develop. Mostly cloudy skies help keep temperatures from tanking as much as last night. It’s still plenty cold with lows in the teens to near 20. Confidence: Medium

Tomorrow (Thursday): Any early-morning snow should move out pretty quickly, giving way to partly to mostly sunny skies and a touch warmer temperatures. However, the warmer highs - in the upper 20s to low 30s - are mostly negated by winds gusting 25-30 mph from the northwest. Confidence: Medium-High

Tomorrow night: Winds diminish as high pressure slides overhead. Another very cold night awaits as lows sink to the teens to low 20s under partly cloudy skies. Confidence: Medium-High

A LOOK AHEAD

Friday starts off cold and cloudy through the morning. The afternoon into evening could feature a period of snow (maybe some sleet mixed in) as low pressure approaches from the west and then re-develops to our east. Possible scenarios range from no accumulation to an inch if we get caught in a “snow hole” between the two lows, to a few inches if the system can muster enough moisture. As of now it’s looking like less rather than more. Anything that does fall would definitely stick with highs in the upper 20s to near 30, and Friday night lows in the mid-teens to low 20s. Confidence: Low-Medium

The weekend shapes up as partly to mostly sunny and continued cold. Saturday highs stall out in the upper 20s to low 30s with a chilly breeze from the northwest, before Sunday highs try to improve to the mid-to-upper 30s. How about Saturday night lows? Upper teens to low 20s. Confidence: Medium
