FORECAST IN DETAIL

Two nice days in a row are going to spoil us. If we keep the clouds at bay, tomorrow’s high could reach the record of 81 National/80 Dulles. A few showers zip through Friday night. Some more rain may develop Saturday morning, before gradual clearing during the afternoon. This should allow perfect viewing for the “super full moon” that rises that night (closest full moon to the earth since 1993). The vernal equinox greets us Sunday with a perfectly seasonable day to mark the astronomical beginning of spring.

Today (Thursday): Saint Patrick’s Irish eyes are indeed smiling on us today with non-stop sun and readings in the 60s by midday. With just a wee bit of luck we could hit 70 for a high. Only a light zephyr from the west means we can take full advantage of that warmth. Confidence: High

Tonight: A stroll in the evening is mighty fine with upper 50s to lower 60s and still a treat as winds are calm. Lows should reach the low 40s in the cool spots to the upper 40s downtown by daybreak. Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Friday): A sunny start to the day allows temperatures to quickly climb to the 60s in the morning. However, winds from the west at 10-20 mph wil kick those readings well into the 70s by early afternoon. High clouds begin to impinge on the area around midday and just how quickly they arrive should determine whether we take a crack at 80. Confidence: Medium-High

Tomorrow night: A light wind from the north in the evening is really the only clue that a cold front is slipping through the area. An evening in the 60s is worth getting out for! Any showers won’t arrive until well after midnight and should be very light (50% chance). Lows should only end up in the upper 40s to lower 50s. Confidence: Medium-High

A LOOK AHEAD

Saturday (updated 10:15 a.m. Thursday morning) could have (40-50% chance) occasional light showers lasting through the morning as a wave forms along the cold front slowly pushing south. Breezes from the north import cooler air. Depending on when the clouds break, highs could reach into the 60s or - if the clouds hold into the early afternon - maybe only near 60. As the afternoon wears on, skies gradually clear. If you have a chance, take the time to watch the moonrise at 7:40 pm. The moon appears just about as big as it ever will and this is exaggerated even more when it is on the horizon. You may want a jacket as readings will be dropping through the 50s. Lows reach the mid-to-upper 30s. Confidence: Low-Medium

Sunday should be one of those most unusual days, perfectly seasonable. High pressure overhead keeps skies clear most of the day allowing highs to reach the mid-to-upper 50s. A storm in the Midwest should lead to increasing clouds late in the day just in time for the vernal equinox that arrives at 7:21 pm EDT. Everywhere on the globe will share a day of roughly equal hours of day and night. A cloudy overnight slows the cooling for our 12 hour night. Lows reach the upper 30s to lower 40s. Confidence: Medium

If the song is right, Monday is “gonna get you down” with a few light showers during the day (40% chance) under a thick overcast. Highs struggle to the low-to-mid 50s. Confidence:Low-Medium
