Today is unmistakably wintry, with the opportunity for some snow tonight. But then the rest of the work week is more on the mild side, starting with tomorrow afternoon, when the mercury takes a ride towards 50. On Thursday or Friday, a 60-degree reading might be within reach, but all indications are that the weekend starts to turn cooler again.

Today (Monday): Increasing clouds and quite chilly.  Highs range from the low-30s in the colder suburbs to the mid-30s downtown.  Winds are light from the north. Confidence: Medium-High

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

6 (→) We try to squeeze out a quick inch of snow Monday night. Will be close.

Tonight: Snow is likely to develop, sometime between 11 p.m. and 1 a.m. It may, however, be patchy in coverage rather than widespread.  A quick coating to a couple inches (depending where the heaviest bands set up) could fall, possibly mixing with sleet for the District and points south and east. Whatever snow that falls should stick given recent cold temperatures. The precipitation ends before dawn most spots, with lows 25-30 (suburbs to city). Confidence: Medium

Programming note: We’ll have more of  a detailed update on the snow possibility tonight in the mid-afternoon.

Tomorrow (Tuesday): Cloudy skies begin to partially clear pretty early in the day as our little snow system scoots away. It becomes mostly sunny in the afternoon and not as cold with highs in the upper 40s to low 50s. Confidence: Medium-High

Tomorrow night: Partly cloudy and not as cold, lows range from the upper 20s in the colder suburbs to low-to-mid 30s downtown. Winds are light, from the south. Confidence: Medium-Hgih


Wednesday’s a tricky forecast.  Some of the models hint that a backdoor cold front could drop down, holding highs in the 40s with considerable cloudy cover and a cool north breeze.  On the other hand, if that front stalls to our north, we should attain 50 with a prevailing wind out of the south. Either way, I wouldn’t be surprised to see some large differences in temperatures from south to north over the region, so stayed tuned to coming forecast updates so we can refine this. Partly cloudy Wednesday night, with lows 29-37 (suburbs-city).   Confidence: Low-Medium

By Thursday, a warm front should have pushed through the area, allowing at least partial sunshine while giving temperatures a boost into the mid-50s (at least). Partly cloudy and mild Thursday night, with a slight chance of a shower, and lows 45-50. Confidence: Medium

A cold front charges through the region Friday. Before it arrives, temperatures may briefly spike well into the 50s to near 60. But then showers, and even a little thunder, are likely to roll through the area. The timing of these showers is tough to pin down, but we favor between early and late afternoon.  Behind the front, temps hold more or less steady until the sun goes down. Friday’s overnight lows should be mostly in the 30s. Confidence: Medium

It turns cooler Saturday (compared to Friday) but we’ll have to watch the possibility of low pressure developing to the south and spreading some chilly rain back into the region late Saturday into Saturday night.  Highs Saturday are in the 40s, with lows Saturday night in the 30s. Confidence: Low-Medium

For Sunday, there could be some lingering rain showers and/or snow flurries. Then it becomes partly cloudy, windy and cold, with high temperatures steady in the 30s. Confidence: Low-Medium
