D.C. area forecast: A partly sunny Thursday but all attention focuses on Sandy’s weekend approach

10:30 a.m. update: The marine layer (low clouds and fog) has come in stronger than expected, so we may not see breaks in the overcast until this afternoon. That means high temperatures may be closer to 70 than 75. We’ve removed our “nice day stamp” from this forecast.

FORECAST IN DETAIL


Now I have had plenty of forecasts where the current day’s outlook was not nearly as interesting as the weekend. This time the weekend is a doozy! The next two days, morning fog notwithstanding, are very pleasant. I just hope we don’t have to pay the price for this. Several models are projecting a track for hurricane Sandy up the coast close enough to at least give us some very strong winds late Sunday into Monday. Some runs hit us with some hefty rains as well. However, there are still some respected hurricane models that take it far enough northeast to spare us.


Clouds: Latest mid-Atlantic infrared satellite shows movement of clouds over past two hours. Refresh page to update. See more maps on our Weather Wall.

Today (Thursday): There is a good chance for a little patchy fog this early morning but it should quickly burn off as the sun has a paucity of clouds to deal with. However, today has less potential to hit the 80s as an wind blows in from the coast and moderates readings. Highs still reach the mild mid-to-upper 70s. Confidence: Medium-High

Tonight: The evening is still a delight with readings around 70 under starry skies. A very light breeze from the east continues to pull in moisture from the Atlantic and with our longer nights, the chance for more widespread fog is a good bet. Lows reach the mid-to-upper 50s. Confidence: Medium-High

Tomorrow (Friday): This is another calm before the possible storm kind of day. It may take a little longer to burn off the fog but by mid-morning sunshine should be abundant. By later in the afternoon we could already begin to see a few high clouds from Sandy but the storm should still be off the east coast of Florida at this point. Highs should be in the low-to-mid 70s. Confidence: Medium-High

Tomorrow night: The high clouds increase over the area blocking out any glimpse of stars. Winds from the east remain very light and evening readings in the 60s are great for going out. Lows end up in the mid-to-upper 50s. Confidence: Medium-High

A LOOK AHEAD

Saturday dawns overcast and breezes from the northeast steadily pick up the pace during the day hitting 10-15 mph and a few scattered light showers are possible especially late in the afternoon (20% chance). Highs should do no better than upper 60s to lower 70s unless we get a break in Sandy’s outer cloud bands. Shower chances increae to 30% overnight and winds continue to slowly increase now out of the north at 10 to 20 mph. Lows reach the low-to-mid 50s. Confidence: Medium

Sunday we are likely to have a real conflict going on between a strong cold front trying to push in from the west and Sandy potentially making its closest approach. This should lead to increasing winds and shower chances (30 percent in the morning, increasing to 60 percent by evening). Temperatures are stuck in the mid-to-upper 50s, very untropical. At night, winds increase with at least a few showers likely (60% chance) and a smaller chance for driving rain. Overnight lows fall even further as the cold air from the west pours in and 40s dominate. Confidence: Low

Monday could end up with tropical storm force winds and heavy rains based on a few recent model runs but could also end up clearing and cool if the storm passes to our northeast as other models are still indicating. Best call at this time is Sandy is still close enough to keep us cloudy and breezy with a few showers (60% chance) and highs only near 50. Stay tuned! Confidence: Low
