P.M. Update: Late-night flurries possible, with some more snow or rain showers Tuesday
Highs in the mid-40s today were pretty close to normal as we kick off the first full workweek of 2021. Other than some occasional sunshine, clouds tended to rule. That’s the case tonight (minus the sunshine!) and into Tuesday. With an active and fast jet stream overhead, some snow or rain showers roll by late tonight into Tuesday.
Through Tonight: Skies will remain mostly cloudy this evening. We could see skies break at least a bit later at night, but clouds will be numerous overall. A couple of flurries or a snow shower are possible by late night. Lows will end up in a near-30 to mid-30s range. Winds will be light from the north and northwest.
Tomorrow (Tuesday): With a lot of cold air aloft, skies will again be rather cloudy. Some mood-enhancing snowflakes will be possible in the morning, turning more toward sprinkles or rain showers later. But there shouldn’t be much concern given highs will be in the near 40 to low 40s zone. Winds will be from the northwest around 5 mph with gusts near 10 mph.
