8:15 a.m. update: Many areas had fog and/or cloudy skies early, but there are plenty of breaks in the cloud cover showing up, with some spots even mostly sunny. That should help temperatures get to at least 70 in many areas. The wild card is a disturbance to our west/northwest bringing showers and storms to the mountains. They’re not holding together well but some showers/storms in the metro area may redevelop this afternoon any time. Bumping rain chances up to 30-40% (from 20% below).

Morning fog followed by the eventuality of some sunshine and warmth - the trademark weather of coastal southern California - visits the D.C. area through midweek. However, a few showers are possible this afternoon. By Thursday and Friday, we lose the morning marine layer taking temperature to new heights - perhaps up to 80 or so - and it’s totally dry. From this vantage point, the weekend looks unsettled - but uncertainty is high.
Today (Monday): Fog and/or low clouds are a good bet in the morning. The question is if and when clouds erode. Most spots should get some sun by mid-to-late afternoon - but it’s not guaranteed. Where the sun bursts out, highs reach the upper 60s to low 70s (favored west and southwest) - where it doesn’t (locations east and northeast of D.C. most likely) mid-60s are the ceiling (and it could be cooler). I have to throw in a 20% chance of an afternoon shower or thundershower, mainly north of D.C. as a weak disturbance swings by. Winds are light from the southeast Confidence: Medium
Tonight: By evening, we may have lost a good deal of the cloud cover from earlier in the day. But low clouds and fog likely develop pre-dawn. Lows are mild, ranging from the upper 40s to low 50s. Confidence: Medium-High

Tomorrow (Tuesday): Flow from the east may sock us in with low clouds for a better part of the day. Of all the days of the work week, this one appears most cloudy. Still, there’s a chance some spots break out into sunshine during the afternoon. Given the likelihood for more afternoon clouds compared to Monday, I’m dropping forecast highs a few degrees - ranging from 64-71. Confidence: Medium
Tomorrow night: Same deal as the last several nights. We may well have some evening and/or overnight breaks in the cloud cover to be followed by low clouds and fog by morning. Lows range from 50-55. Confidence: Medium-High
Wednesday is yet another day when we may have to contend with morning low clouds and fog, but the afternoon offers promise of sunshine and higher temperatures compared to Tuesday. Highs Wednesday range from the upper 60s to mid-70s. Partly cloudy Wednesday night, with lower fog chances compared to previous nights, with lows 52-56.
Thursday and Friday both look terrific and unseasonably mild. Each day should have a good deal of sunshine which, along with flow from the south, help push high tempertures to near 80. Thursday and Friday nights are both partly cloudy, with lows 47-55 (suburbs-city) Confidence: Medium-High
Of the weekend days, Saturday is probably the better of the two. A disturbance is forecast to slowly move towards the region. It may well stay to our south, but clouds should increase on Saturday and there *might* be showers by Saturday night into Sunday. But the exact evolution (track, speed, strength) of this disturbance is uncertain - so stay tuned for updates for your weekend planning. We stay mild, with highs near 70 on Saturday and in the 60s Sunday. Overnight lows are in the 50s. Confidence: Low-Medium
