FORECAST IN DETAIL

What a fantastic Friday. But it goes downhill a bit from here. Late tonight and tomorrow morning we have some threat of a few showers, and a cooler temperature regime entering the picture as a cold front passes through. Temperatures stay mainly in the 50s this weekend, perhaps popping above 60 (more likely tomorrow than Sunday). By Monday, clouds and showers move back in. Temperatures won’t be cold, at least, near 60 or above -- just a bit gloomy! All the more reason to savor today.

Today (Friday): Woo! Not only plentiful sunshine but neither pollen nor humidity are major concerns! High temperatures will be up there -- warmer than yesterday. Highs? At least mid-70s, with 80 degrees possible south of town. If we see full sun and persistent warm gusty downsloping winds, we could near the record of 81 at National Airport. Breezes ranging from 5 to 15 mph out of the west and northwest could bring gusts near 30 mph. Confidence: High

Tonight: Slowly, and mainly quietly, a cold front begins passing through the area. Skies go from partly cloudy to very cloudy after midnight -- with a 30% chance that showers may sprinkle on your parade if staying out late. A slight northerly breeze keeps it cool, but clouds keep temperatures from dropping below the mid-40s, to around 50 downtown. If you’re planning a dinner tonight, try eating outdoors early, while temperatures are still in the 60s. Confidence: Medium

Tomorrow (Saturday): The morning hours may still be quite cloudy with a 30% chance of a lingering shower. But good news for afternoon picnickers, the moisture associated with this cold front moves through. By later in the day it’s mostly sunny, though we will have some light breezes out of the north adding a cool tinge to the air. If clouds hang on more than expected into the mid-afternoon, we may level-off in the upper 50s. Should we clear quicker & more fully by 12:30 or 1:30pm, temperatures above 60 become more likely! Confidence: Low-Medium

Tomorrow night: We start cool -- in the 50s -- during evening hours, before turning a bit nippy by sunrise -- in the mid 30s outside the Beltway, perhaps 40 downtown. Hope you enjoyed Friday’s taste of warmth? Confidence: Medium

Sunday: Dry and sunny. Near average temperatures appear to be on tap, with highs in the mid-to-upper 50s. 60 can’t be completely ruled out, should we see full sun all day. But clouds may threaten by sunset, if our next weather system speeds up a bit. FYI, 7:21pm is the official time of the equinox! Confidence:Low-Medium

A LOOK AHEAD

Sunday night could be fully cloudy if the storm system out of the Midwest speeds up at all. Low temperatures for our first (official) night of spring could be nippy again. Low temperatures may near the mid-30s in typically colder spots and downtown may dip into the lower 40s. A few showers are possible by dawn. Confidence: Low-Medium

While showers chances increase for the workweek, so do temperatures, at least slightly. Monday appears overcast with a few light showers (50% chance) during the day. But there is still a chance of a couple bright-ish moments. Depending on how much, decently strong, March sunshine we can filter through any breaks in the overcast, highs could be anywhere in the 50s. Upper 50s if we can get a break! Tuesday could be a bit warmer, into the mid-to-upper 60s ahead of our next storm system. Clouds could be substantial, along with a continued (30-40% chance) of showers. Confidence: Low
