Moist flow straight off the Atlantic Ocean will cover us in clouds and keep us cool today. Milder flow from the south will take over Sunday but gusty showers are likely to douse us late thanks to a cold front. Drier and more settled conditions should arrive for Christmas Eve.
TodayDamp and dreary, mid 40s.
. With persistent easterly flow, we'll be socked in with clouds, patchy drizzle and a slight chill. I'd call it a good shopping day. Temperatures should only rise a few degrees during the day - maybe to 45, 46 or 47 in spots. Overnight, clouds and drizzle will likely persist with temperatures pretty much steady in the low to mid 40s.Clouds mute Thursday's sunset near Tyson's Corner.

SundayMostly cloudy and mild with PM rain, upper 50s
. Winds will become southerly, boosting temperatures a good 10 degrees relative to today. However, a cold front will move through in the evening with showers and thunderstorms developing during the mid to late afternoon (most likely time frame 4 to 7pm). Heavy rain and gusty winds are possible. After some evening showers (through 9pm or so), gradual clearing and breezy Sunday night, with lows 30-35 (suburbs-city)
Christmas EveMostly sunny and seasonably cool, mid to upper 40s.
High pressure will build into the region from the west giving us a good deal of sunshine. A northwest breeze will blow (10-20mph), making those mid to upper 40s feel more like the upper 30s to around 40. Overnight the winds will subside under clear skies, with low temperatures 25-30 (suburbs-city).
Christmas Day Outlook
As of now, I'm expecting cool and dry conditions with highs generally in the low 40s. However, we'll need to keep our eye on an upper level disturbance to our southwest which may increase cloud cover during the afternoon. There's even an outside chance of a snow flurry or sprinkle towards evening and overnight. Stay tuned...
