FORECAST IN DETAIL
At least we made it through two out of three holiday weekend days with little rain to speak of. Today we won't be so lucky. On and off showers are likely, initiating what appears to be a rather wet week. Rain stays in the forecast through Friday. The light at the end of the tunnel is the sunshine forecast for next weekend.
Radar: Latest D.C. area radar loop shows movement of precipitation over past two hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.
Today (Monday): A slow-moving cold front north of the region will slide southward, producing periods of showers and thunderstorms. The greatest coverage and intensity of rain will occur in the afternoon and evening (70% chance), though some showers can't be ruled out in the morning (40% chance). It shouldn't rain the entire day, and there may be windows for outdoor activities. Cloud cover will hold high temperatures to near 80. Confidence: Medium-High
Tonight: Showers will continue through midnight or so, and then gradually diminish as the cold front pushes south of the region. Lows will drop to near 60. Confidence: High
Keep reading for the forecast through the weekend....
Tomorrow (Tuesday): A cool, damp fetch from the east will result in cloudy skies and temperatures about 10 degrees cooler than today. As yesterday's cold front returns northward as a warm front, showers and possibly a few thunderstorms will resume, particularly in the afternoon. Highs will be in the mid-to-upper 60s. Confidence: Medium
Tomorrow Night: Showers are possible through midnight, followed by partly cloudy skies and perhaps some fog by morning. Temperatures should remain steady, in the mid-60s. Confidence: Medium
Warm air returns Wednesday as winds switch around to out of the south. Some sunshine should also return, with highs back up to near 80. A few late afternoon or evening storms could (30% chance) pop in the unstable air. Partly cloudy and mild Wednesday night, with lows in the mid-to-upper 60s. Confidence: Medium-High
Thunderstorm chances increase Thursday (50% chance) as the next cold front closes in on the region. Prior to the development of storms, it will be warm and and muggy, with highs 80-85. Showers and storms may continue into Thursday night (40% chance), with lows 60-65. Confidence: Medium-High
Assuming the cold front advances to our east by Friday morning, Friday may end up being dry and less humid. However, especially east of I-95, the front may still be clearing the region, keeping a chance of showers and storms in the picture (30% chance). Highs should be in the mid-70s to near 80. Confidence: Low-Medium
Strong high pressure looks to clear us out by the weekend. Both days show strong potential for sunshine, with highs in the mid-70s with overnight lows in the 50s. Confidence: Medium

No rain yet in Baileys Crossroads area...skies mainly cloudy with some evidence of convection.
Weekend dances thus far have been generally rain free...still have this evening and tomorrow night to go. Tomorrow sounds like another of those miserable rainy days.

Weather here in Herndon has been mostly sunny all day. I could use rain today, as I planted stuff and don't really want to have to haul out the sprinkler or untangle the soaker hoses. Looking at the radar, it would seem that DC and areas due west are in the dry slot as usual, at least for the moment.
Bombo, as a fellow dancer I wish you rain-free dances, as long as gardeners get rain during the non-dance, non-travel hours.

There's a wall of water outside my window in Lake Ridge...been like this for about a half an hour. Just had the first low roll of thunder, too.
Have a safe Memorial Day!
