Yesterday’s highs of 44 (Dulles) and 46 (National) were still on the chilly side yet, but daytime temperatures for the rest of this week promise to be warmer as our air mass moderates. Also, an approaching cold front sends milder air out ahead of it. In addition to the warmer weather good news, we also see only limited chances of rain this week (a welcome reprieve from last week’s excessive gully-washer!). The weekend looks mostly dry at this point, but temperatures may sink back down toward the slightly colder side again.
Today (Tuesday): High pressure continues to sit overhead, delivering a full day of full sunshine. The cold air mass of recent days finally starts to modify too, so expect temperatures to push into the upper 40s and low 50s with light winds from the north. Confidence: High
Tonight: Partly cloudy skies should keep temperatures from dipping quite as cold, especially in the city. Look for a broad temperature range from the middle 20s in the outer suburbs to the middle 30s in the city. Light winds again. Confidence: High

Tomorrow (Wednesday): As high pressure edges off the East Coast, we should see temperatures trend warmer yet again, but we have a complicating factor of increasing cloud cover, especially in the afternoon. Right now, we’ll aim for low-to-mid 50s, but there is a slight risk it may be cooler. Winds are light from the south and southeast. Confidence: Medium-High
Tomorrow night: Mostly cloudy with lows ranging through the 30s. Winds mostly light and come from the southwest. Confidence: Medium-High
Thursday features the approach of a cold front. Winds from the southwest should offset partly to mostly cloudy skies and push our temperatures into the mid-to-upper 50s. By afternoon into early evening, watch out for scattered showers ahead of the front (40% chance). The guidance is suggesting precipitation totals will be on the light side, a stark contrast to last week. Mostly cloudy Thursday night with temperatures only dipping into the low-to-mid 40s. Confidence: Medium
Friday finds high pressure struggling to return with limited cold air supply. What that means for us is partly cloudy skies with temperatures still on the milder side (low-to-mid 50s). Friday night is partly to mostly cloudy, but colder with lows in the low-to-mid 30s. Confidence: Medium
The weekend could be slightly complicated on Saturday morning with clouds and a shower chance (30%), but otherwise, clearing skies by later Saturday and partly to mostly sunny skies on Sunday are expected currently. Temperatures should lean to the colder side with highs in the mid-to-upper 40s and lows Saturday night in the upper 20s to mid-30s under partly cloudy skies. Confidence: Low-Medium.
