D.C. area forecast: Cool, damp and gloomy today; warm tomorrow, with thunder late? Posted at 05:00 AM ET, 12/09/2012 Today: Cloudy with some showers/mist likely. Chance of p.m. showers and t'showers. Generally gloomy skies and some likely showers and/or mist do little to lift the spirit of the season. Not the greatest of days. The word of the day is "gloomy." Hopefully you've already got your decorations up outside because today is not the day to do it. With showers around and maybe some fog, too, temperatures go nowhere fast. But that changes as a warm front moving through tonight sends tomorrow's highs well above average. The warmth is short-lived, however, as a good chance of Monday evening showers and possibly some thunder usher in cooler air more akin to the season. Today (Sunday): Easterly flow off the ocean keeps the air cool and clammy. Some showers are likely as well, especially during the morning and early afternoon from around I-66/D.C./Route 50 and to the north. Even where it's not outright raining, there could be fog and drizzle or mist. Still, it doesn't look like a washout, and shower activity should lessen for the mid-to-late afternoon even if drizzle or mist linger. Overcast skies and the moisture cap highs in the upper 40s to low 50s. Tonight: A warm front works its way through during the overnight eventually putting an end to any light rain or drizzle that lingers into the evening. Temperatures also bump up a bit after the front goes through, rising from around 50 during the evening into the mid-50s overnight or by dawn. Keep reading for the forecast through midweek... Tomorrow (Monday): Temperatures warm nicely in the wake of the warm front, but your exact location likely plays a large role in just how warm it gets. Around town most of us should hit highs in the mid-60s to near 70 with mostly cloudy skies. More clouds associated with an approaching cold front may keep highs far north and west (e.g., Frederick and Loudoun counties) in the low-to-mid 60s, while a bit more sun could get highs far south (e.g., Stafford County and Southern MD) into the low-to-mid 70s. The approaching cold front brings a 30% chance of afternoon showers (and maybe a rumble or two of thunder) mainly for areas north and west of town. Tomorrow night: Showers are likely during the evening - and with the warmth ahead of the front, a few rumbles of thunder are possible as well - before rain chances decrease overnight as the cold front starts to head to our southeast. Warm evening temperatures fall off overnight as winds become breezy from the northwest. Most see lows by morning in the upper 40s. Skies turn partly sunny for Tuesday and Wednesday. But we can't rule out a shower with the front stalled to our southeast. Temperatures return to normal for this time of year, with much cooler highs in the upper 40s to near 50, and Tuesday night lows from near 30 to the mid-30s.
