PM Update: Cold tonight, milder Saturday

Rain Sunday, possibly ending as snow showers

We welcomed the first flakes of the winter this morning, but more tranquil weather arrived this afternoon as temps climbed into the upper 30s. For the fifth straight day, it looks like the mercury will fail to reach 40 at Reagan National Airport - the longest such stretch since February 5-10 earlier this year when we were dealt knockout blows by Snowmageddon and Snoverkill. Temperatures will gradually fall through the 30s this evening as cloud cover departs.

Through Tonight: It's another cold night as the clearing skies allow temperatures to drop back into the 20s throughout the region. Lows range from the upper 20s downtown to the low 20s in the colder suburbs.

Tomorrow (Saturday): Winds from the southeast ahead of the next storm system bring some moderation in temperatures. Highs head up into the mid-40s. Sky cover varies from mostly sunny in the morning to mostly cloudy by evening. Some light rain may develop during the evening. In the far north and west suburbs like western Loudoun, northwest Montgomery and Frederick counties, the rain may begin as a brief period of sleet and/or freezing rain.

2010 warmest on record: Over at PostCarbon, Juliet Eilperin reports "new temperature readings released by NASA's Goddard Institute of Space Studies show 2010 now ranks as the hottest climate year on record." She adds: "The findings are significant, according to experts, and barring some temperature anomaly in December, should place 2010 as the warmest year on record overall."
