FORECAST IN DETAIL

Hopefully you’ve weathered the polar vortex with no burst pipes, stalled car or power outage? The chill is still biting this morning, but the end of this intense cold blast is in sight. Light winds plus some sun help today’s highs into the much more reasonable range. We’re steadily warmer tomorrow into the weekend, but with the potential for a light wintry mix Thursday night and mild rain showers Saturday into Sunday.

Temperature Map

Today (Wednesday): The greatest news today is really in the winds. Not only are they light, around 5-10 mph, but they are from the south. That, combined with mostly to partly sunny skies, helps us warm from morning lows in the single digits to mid-teens, to afternoon highs in the upper 20s to near 30. Still cold but nothing like yesterday. Confidence: High

Tonight: Skies turn partly to mostly cloudy, which is welcome news since the clouds will help keep temperatures up and take some pressure off those heating units. Lows should bottom in the upper teens to mid-20s. Confidence: High

Tomorrow (Thursday): So we’re still well short of reaching Nice Day Sun territory, but temperatures do continue to trend in the right direction as high pressure remains in control. Highs should climb to the upper 30s to near 40 under partly sunny skies, and with light winds from the northeast. Confidence: Medium-High

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

2 (↑) Late Thursday-Friday looks light but could cause a few wintry issues. No concrete threat thereafter.

Tomorrow night: We cloud up again and a weak little system brings a 30-40% chance of light snow, sleet and/or rain, as overnight lows dip to the upper 20s to low 30s. Still a bit early to tell if there’s going to be enough wintry precipitation with this system to cause any problems heading into Friday morning. Confidence: Low-Medium

A LOOK AHEAD

Any light mixed precipitation or rain early Friday (30-40% chance) should give way to partly sunny skies and highs in the low-to-mid 40s. Mostly cloudy Friday night, with perhaps some drizzle and lows in the 30s. Confidence: Low-Medium

The weekend is looking unsettled with potentially two systems coming through. Rain showers are possible both days, but there is little to no risk of frozen precipitation. Highs should warm into at least the 50s each day with Saturday night lows in the 40s, as the polar vortex becomes a distant memory. Confidence: Medium
