7:00 AM | ***Another powerful Arctic frontal passage to spark snow showers late today/early tonight and possible heavier snow squalls...brutally cold air will follow for Thursday into Saturday...sub-zero temperatures possible with this next Arctic blast***

6-Day DC Forecast

Today

Becoming mostly cloudy, still quite cold, snow showers possible by late afternoon, perhaps even a heavier snow squall or two, highs near 30 degrees

Evening snow showers, possibly a heavier snow squall or two, a coating to an inch of new snow accumulation is possible along with slick spots on roadways, turning breezy and brutally cold by morning with lows in the upper single digits

Thursday

Bitter cold with variable clouds, windy, still the chance for a few snow showers, highs only reaching the low-to-middle teens

Friday

After a possible sub-zero start continued bitter cold with partial sunshine, breezy, highs only reaching the upper teens

Saturday

Mostly cloudy, still quite cold, but not as harsh, chance for snow late in the day and then a mixed bag of precipitation at night, near freezing for highs

Discussion

Another powerful Arctic front is approaching the I-95 corridor and it is likely to spark some snow shower activity from late today into tonight and there can be a heavier snow squall or two. In fact, it is not out of the question that there be a quick coating to an inch of new snow given the strong upper-level energy that is associated with this surface frontal system. Once this front passes through the region, incredible cold Arctic air will flood the region. The period from late tonight into early Saturday will be frigid indeed with amazing sub-zero low temperatures likely on Friday morning - perhaps even record-breaking. Saturday starts off very cold, but it’ll turn milder late in the day along with the chance for some snow. By Saturday night and Sunday, it should become mild enough for a mixed bag of precipitation to be followed by plain rain with high temperatures reaching 45 degrees late in the weekend before yet another very cold air mass arrives for the early part of next week.
