While not as warm relative to average as much of March, the first week of April promises to be delightful. Most days feature abundant sunshine with temperatures in the 60s and crisp, cool overnights. The best chance for showers is sometime Wednesday; otherwise, dry weather dominates. It’s premature to worry about drought, but area rainfall deficits are mounting.
Today (Monday): There may be a few lingering early morning clouds, but skies gradually become mostly sunny. A brisk wind from the north around 15 mph (with some higher gusts) offsets some of the sun’s warmth, with highs unable to do much better than the low-to-mid 60s. Confidence: Medium-High
Tonight: Clear and quite chilly, with diminishing winds. Lows range from the low 30s in the colder west and north suburbs to the low 40s downtown. Scattered frost is possible in those colder locations (western Fairfax county to northern Montgomery county and to the north and west). Confidence: Medium-High
Keep reading for the outlook through the weekend.
Tomorrow (Tuesday): Following a crisp start, beautiful sunshine lifts temperatures on a 30+ degree upward ride. Highs reach 65-70... a few high clouds may increase late. Winds are from the southwest at 5-10 mph. Confidence: Medium-High
Tomorrow night: Clouds increase ahead of the next weather system, and there’s a very slight (20%) chance of showers late at night. The clouds and southerly flow keep low temps in the fairly mild upper 40s to low 50s. Confidence: MediumA LOOK AHEAD
A weak cold front slides by Wednesday offering a 30% chance of showers. Skies are mostly cloudy, with highs in the mid-to-upper 60s. Partial clearing Wednesday night, with lows in the 40s. Confidence: Medium
On Thursday, partly to mostly sunny skies early may yield to some increase in cloud cover as low pressure approaches from the southwest. The low should stay far enough south to keep us out of the rain, but I can’t guarantee that yet. Highs probably reach the low 60s. Canadian high pressure tries to build into the region Thursday night - keeping stormy weather to the south. Assuming that happens (not 100%, but most likely), skies clear with lows from the mid-30s to mid-40s (suburbs to city). Confidence:Medium
By Friday, Canadian high pressure likely establishies itself well enough to produce sunny skies and push any storminess well to our south. But if the high is weaker than forecast, clouds and even showers could enter the forecast. I favor the sunny solution, but with the cool flow of air from the northwest, highs only reach 60-65. Confidence:Medium
The weekend - from this vantage point - looks great. High pressure is in charge, meaning mostly sunny skies and highs in the mid-60s to low 70s. Clear and chilly at night, with lows in the mid-30s to mid-40s. Confidence:Medium
