Mother nature has a keen sense of timing lately, as the overwhelming majority of the season's nasty days have conveniently occurred during the work week. Almost without exception, the weekend days have been beautiful. That's the case again this weekend, with Saturday the sunnier of the two days. Sure enough, the next chance of rain is late Monday into Tuesday.

Today (Saturday): The normally colder suburbs (e.g. Oakton, Manassas, Sterling, Gaithersburg, and Clarksburg) may have some patchy frost early on. But in little time, everyone warms up to above 60 late morning, with afternoon highs near 70. Sky conditions are mostly sunny, with a light wind from the south at 5-10 mph. Confidence: High

Tonight: Flow from the southwest gradually increases the high cloud cover, meaning a warmer night than the previous. Lows range from the mid-40s in the cooler suburbs to the low 50s downtown. Everyone is about 10 degrees warmer than Friday night. Confidence: Medium-High

Keep reading for the forecast into early next week...

Tomorrow (Sunday): The potential is there for a nice day, but it's not a lock due to the possibility of at least partial cloud cover at times. Irrespective of the clouds, warm flow from the south means above average temps with highs 70-75. Confidence: Medium-High

Tomorrow Night: The southerly flow and some cloudiness make for a mild evening with overnight lows 50-55 (suburbs-city). Confidence: Medium-High


Monday is quite the mild day as high pressure offshore continues to pump warm air into the region from the south. But the moist flow may bring considerable cloud cover in the afternoon and the outside (20%) chance of a shower. Highs are in the mid-70s. Showers are more likely (40-50% chance) Monday night, with lows in the 50s. Some shower chances (30%) linger into Tuesday, which is also mild, with highs in the low-to-mid 70s. Confidence: Medium

Centreville VA Had the lightest & briefest of early morning frosts here. Digital thermometers read 36 & 35 as lows last night, but there are frost patches on neighborhood roofs.
The basil is very unhappy, but it ain't dead yet.

CWG! Can you speculate on the weather for the morning of Sunday the 31st? I'm running the Marine Corps Marathon!

CBOFS suggests we might have a decent southerly breeze on the Potomac River at DC tomorrow, peaking in mid-day. Would CWG agree with that?

Looks like CWG is off for the weekend, asleep at the wheel . The written forecast mentions no possibility of rain, yet the at a glance shows 60% chance. This is not the first time that our fearless forecasters forget about the weekend.

Only light and patchy frost Sat. a.m. in Harpers Ferry. I was hoping for colder, to whack some of these stink bugs and hornets. And an end to the mowing season would be nice.

Not sure what rain you were talking about. Our weekend forecast never included the chance of rain because there wasn't any. We update the forecast each weekend day as needed and there was no need.

Still a bit skeptical about that rain forecast for tomorrow. There seems to be little or no synoptic support other than perhaps the nose of a jet streak at upper levels.
