FORECAST IN DETAIL

Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

Today is about as “normal” as you are going to get for this time of year. Speaking of normal, tomorrow marks the climatological bottom of the trough for winter temps! However, from the looks of some of the models that may not feel like the case in the next couple of weeks as more of that nasty polar vortex comes spinning our way. As for the MLK weekend, not bad at all. A couple of spritzes possible most likely Friday night and again Sunday morning but I am betting the sun clocks more time than clouds on the average.

Today (Thursday): Clouds are still likely to greet the early risers but they should evaporate quickly by mid-morning. However a colder airmass overhead keeps a lid on temperatures with highs stuck in the low-to-mid 40s. Given the light winds and sun’s dominance, the comfort factor should be reasonable. Confidence: High

Tonight: A clipper system begins zipping across the Midwest overnight and ahead of it our clouds  gradually increase after midnight. Winds are only light from the south. Lows range from the mid-20s suburbs to near 30 downtown. Confidence: 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 (→) D.C. is Disappointing City for snow fans; little chance of more than dusting thru Monday.

Tomorrow (Friday): Clouds are only likely to give a few brief glimpses of the sun. There is a slight chance of a rain sprinkle or even a  snow flurry west of town at some time during the day, but it will be the exception to the rule. Highs should hold in the low-to-mid 40s. Winds remain light out of the south.  Confidence: Medium-High

Tomorrow night: The clouds hold and it looks like the best chance for snow showers could be in the middle of the night, not that I am encouraging anyone to stay up. There is only a 30% chance of even the lightest of dustings. Lows bottom out in the mid-to-upper 20s. Confidence: Medium

A LOOK AHEAD

Saturday should clear up nicely but the real heart of the cold air is overhead. That keeps highs in the mid-to-upper 30s. Fortunately, winds are light so not too much of a bite! The night starts out starlit and later in the evening, the moon rises in conjunction with one of the brightest stars in the sky, Regulus. However, clouds are likely to quickly increase as another clipper zips into the area giving us yet another 30% chance of a dusting of snow late night. Lows drop into the 20s (lower burbs, upper downtown). Confidence: Medium-High

Sunday should see skies quickly clear in the morning as the clipper moves out to sea. The good thing about the system is that it helps to begin pulling the cold air out of the region but it does it with some pretty strong westerly winds that should make the highs in the low-to-mid 40s not so pleasant. Winds gradually die down overnight with lows mainly in the mid-to-upper 20s. Confidence: Medium

Martin Luther King Day (Monday) is a good day to go visit the MLK memorial with plenty of sun, light winds, and highs reaching the mid-to-upper 40s. Enjoy it, for it looks like the next Arctic surge heads into town the following day. Confidence: Medium
