FORECAST IN DETAIL


Ever since Hurricane Sandy’s approach, temperatures have been colder than normal in the region. That remains the case through midweek as another storm makes a run at the area. How much precipitation we get from this storm is unclear, but - at least in our colder spots - some wet snowflakes are a small possibility late Wednesday. By the weekend, we start to warm up a bit.

Today (Monday): All of us start off the day in the 30s, with some of the cold spots below freezing. Like Sunday, we see a good amount of sunshine, but highs in the upper 40s to low 50s are the best we can do. Winds are from the north at 5-10 mph. Confidence: Medium-High

Tonight: Coldest night of the season so far? Very possibly. Freezing temperatures may edge inside the beltway, with lows from the upper 20s in the cooler suburbs to the mid-30s downtown. A few high clouds *may* prevent a more widespread freeze. Winds are light from the north, under 5 mph. Confidence: Medium-High

Tomorrow (Tuesday): Mostly sunny in the morning before high clouds advance into the area. It remains quite chilly, with highs 46-51. Winds are from the northeast at 5-10 mph. Confidence: Mediium-High

Tomorrow night: Becoming mostly cloudy. Cold, with lows 35-40 (suburbs-city). Confidence: Medium-High

A LOOK AHEAD

A developing Nor’easter off the mid-Atlantic brings a gradually increasing chance of rain Wednesday with best odds in the afternoon (up to about 50-60 percent) and along/east of I-95. It’s cold and breezy, with highs in the low 40s. Rain (60 percent chance) *may* mix with or change to snow Wednesday night, with lows 32-36. The best chance of snow is northwest and west of the District, especially at elevations above 1,000 feet. The chance of accumulating snow is low. Winds increase, becoming gusty out of the north. Confidence: Low-Medium

Any rain or snow ends Thursday morning. It turns partly sunny, windy and cold with highs only in the mid-to-upper 40s. Clearing Thursday night, with chilly lows from the upper 20s to mid-30s (suburbs-city). Confidence: Low-Medium

A gradual warming trend sets in Friday through Sunday - which should be dry. Friday’s partly to mostly sunny and chilly, with highs near 50. By Saturday, highs moderate to near 60. On Sunday, we may reach into the 60s as winds become more out of a southerly direction. Overnight lows moderate from the 30s Friday night into the 40s Saturday night. Confidence: Low-Medium
