FORECAST IN DETAIL

We have a couple of sunny but chilly days ahead of us. Winds continue to be a factor today with gusts over 30 mph. Then, the story shifts to the next storm system approaching for Sunday. How much wintry or wet weather can we expect?

Today (Friday): It will definitely feel like winter. Sunny skies will be negated by cold temperatures and gusty winds. Wind chills could be in the teens at times. Brrr! Highs top off in the mid-to-upper 30s, with wind gusts perhaps to near 35 mph. Confidence: High

Tonight: Winds begin to slacken. Mostly clear skies allow temperatures to cool quickly, to lows in the mid-20s downtown with some upper teens in the coldest suburbs. West winds 5 to 10 mph will still add a bit of a chill to the already chilly air. Gloves & scarf are highly recommended! Confidence: High

What are the snow chances for Sunday? Keep reading for the forecast into early next week...

Tomorrow (Saturday): Mostly sunny skies prevail through much of the day. And winds should be much more forgiving than on Friday -- around 10 mph or less. While still cold, temperatures will be kinder as well, with highs in the low 40s. High clouds may work their way in during the afternoon or evening. Confidence: Medium-High

Tomorrow Night: Clouds move overhead and thicken as the night goes on, as our next potentially wintry storm system approaches. Lows should be in the upper 20s to low 30s. Snow or a wintry mix could move in before sunrise. Confidence: Medium

Sunday: Some areas could see a morning period of snow or wintry mix, especially from near D.C. toward points north. Precipitation should change to all rain everywhere by late morning or early afternoon. Accumulation of snow and/or sleet is possible before the changeover, but would likely be light. Highs should eventually get to at least the upper 30s to low 40s, which would soften the impact of any wintry accumulation. Confidence: Low-Medium

A LOOK AHEAD

Rain comes to an end Sunday evening or overnight followed by clearing skies. Lows near freezing in the coldest outlying suburbs could mean some patchy spots of ice early Monday morning. Elsewhere, the closer-in suburbs and downtown should only dip to the mid-to-upper 30s. Confidence: Medium

Monday skies should be at least partly sunny with highs in the mid-40s to low 50s. Confidence: Medium

Our active pattern may continue, as there's a chance that another storm system brings precipitation on Tuesday. So far, this one's looking like a rain or mostly rain event. Confidence: Low

I'm having deja vu from previous winters. Freezing cold, then warms up just in time for precipitation giving us cold rain. Then freezing cold again.

Repeat.

Brrr is right. 14.2F this morning up to 24.1 at present.

I would not be surprised if we don't really see any snow with this Sunday system. High pressure due east of us as a system is arriving is not a very favorable setup.

The just-posted Snow Lover's Crystal Ball echoes Ian's sentiment.
