FORECAST IN DETAIL


On the plus side today, there’s plenty of sun, which has been lacking as of late. On the down side, we get a good bit of wind in the wake of yesterday’s storm (the not-so-snowy snow totals), and not a lot of warmth to go with it. Temperatures this week look to stay just on the cool side of normal, with a couple chances for some mainly conversational snowflakes New Year’s Eve and New Year’s Day. We’re watching a more significant storm for around the Thursday-Friday timeframe, though it may miss to the south.

Today (Sunday): From the inside looking out, partly to mostly sunny skies mask the cold and blustery conditions. But once outside you’ll feel the winds from the northwest, sustained at 15-25 mph with gusts to near 35 mph, before slackening toward evening. The winds lock the cold air in place as highs only reach the upper 30s to near 40, with wind chills probably staying below freezing. All in all, a pretty raw day. Confidence: High

Tonight: Winds diminish during the evening and become light overnight. With the dying winds and mostly clear skies overhead, it’s going to be a chilly night. Lows head down to the upper teens to near 20 in some outlying areas, with mid-20s likely closer in. Confidence: High

Tomorrow (Monday): A developing storm system well to our southwest should send increasing clouds our way. Even with partly to eventually mostly cloudy skies, light winds from the southwest are enough to push highs to near 40 to the low 40s. Only a touch warmer than today in terms of actual temperature, but much nicer without the gusty winds. Confidence: Medium-High

New Year’s Eve: There might be a few light rain or snow showers around (30% chance) as we celebrate the beginning of a new year. But right now we don’t expect anything that would significantly disrupt New Year’s Eve plans. Otherwise, it’s a mostly cloudy night with midnight temperatures mainly in the mid-30s, and overnight lows near 30 to the low 30s. Confidence: Medium-High

A LOOK AHEAD

It’s a gray start to the year on New Year’s Day. A weak system may trigger a few light rain or snow showers, but as of now we don’t expect anything in the way of accumulation. There’s still time to monitor this, though. Daytime highs end up in the upper 30s to mid-40s under mostly cloudy skies. Still a chance for a few light rain or snow showers Tuesday night with lows in the mid-20s to near 30. Confidence: Medium

High pressure building in should mean partly to mostly sunny skies as the holiday season comes to a close Wednesday. We stay on the chilly side as well with highs likely in the mid-30s to low 40s. Confidence: Medium
