It’s not a bad end to our holiday weekend as many get back on the roads to head back home. You won’t be fighting much sun glare as you drive through our neck of the woods but it may be a good opportunity to crack the windows a bit as we’re in for another pleasant, albeit cloudy, day. A developing low to our southwest slows down the rain but keeps the southerly flow pumping until finally passing through on Tuesday. In its wake, we’re in for a reality check as November’s end reminds us what time of year it is.
Today (Sunday): A wave develops along our approaching front today, slowing down its progress. Still, clouds make enough of a push that we’ll be looking at partly sunny or mostly cloudy skies for much of the day. That’s about it for the negative side of things though as we’ll once again see temperatures climb up well into the 60s. Confidence: Medium-High
Tonight: A shower or two may break out ahead of the front but should stay to our south-southwest. I won’t completely rule out a sprinkle (10%), but for most, we’ll see overcast skies through the night. Lows drop to near 50 degrees downtown, and the mid-to-upper 40s outside the Beltway. Confidence: Medium-High

Tomorrow (Monday): As the wave stalls and develops to our southwest, we stay underneath mostly cloudy skies but our rain chances are held down to just about a 20-30% chance for a few light showers. Winds should be pumping up warm air from the south, and that keeps our daytime highs in the 60s once more — maybe a touch cooler in the upper 50s if more showers break out. Confidence: Medium
Tomorrow night: The steadier rain begins to make headway towards our region tomorrow night. Still though, the more significant rains look to hold off a little more. We’re calling for a a 50% chance for rain overnight, with perhaps our most southwestern readers seeing some steadier stuff by daybreak. Overnight lows should be held near 50 degrees. Confidence: Low-Medium
By late-morning Tuesday, our system finally arrives. Light-to-moderate showers and maybe a rumble overspreads our area, hopefully exiting by our commute home (it’ll be close). Temperatures should stay fairly steady in the upper 50s to near 60 and begin to slide backwards once the front passes through — you’ll notice as the breezes pick up.
Overnight, we’ll see just a chance (20%) for some additional sprinkles. Otherwise it’s mostly cloudy but clearing, with chillier air working its way in. Lows drop to the upper 30s/lower 40s. Confidence: Low-Medium
On Wednesday we’re definitely in for a change. Those on the western slopes of the Apps could be seeing the flakes fly! For us though, just a chilly, raw day with partly sunny skies and highs only in the upper 40s to near 50. Confidence: Medium
