SNOW POTENTIAL INDEX
A daily assessment of the potential for *accumulating* snow for the next week on a 0-10 scale. More infoFORECAST IN DETAIL
By the end of the work week we’re into March, but the February portion of this week is actually milder. The warmest day of the week is Wednesday, the wettest Tuesday, and the sunniest may well be today. The coldest stretch is probably Friday to Sunday, when highs struggle to crest 40. The average high is now working into the low 50s and Wednesday may be the only day to top it.
Today (Monday): Most spots start the day sub-freezing but sunshine helps us pass 40 by noon. Afternoon highs range from 45-50. Winds - from the northwest at 5-10 mph - are much less gusty than Sunday. Confidence: High
Tonight: Clouds slowly increase overnight, and lower and thicken by morning. We should remain precipitaton-free through sunrise, with lows ranging from 29-35 (suburbs-city). Confidence: Medium-High

Tomorrow (Tuesday): The next storm system moves in producing rain showers - starting mid-morning to early afternoon. Well west and northwest of the District (mainly towards I-81), precipitation may begin briefly as (mainly) non-accumulating wet snow and/or sleet before changing to rain. Rain may become moderate to heavy towards evening. Highs range from the upper 30s in the colder suburbs to 40-45 elsewhere. Confidence: Medium-High
Tomorrow night: Rain is likely and may be moderate-to-heavy before 10 p.m. After midnight, rain decreases in coverage and intensity and temperatures should remain steady near 40 as winds come in out of the southwest. Total rain should average between 0.5-1 inch, with highest amounts probably west of the District. Confidence: Medium-HighA LOOK AHEAD
Wednesday is the mildest day of the week as we get a brief push of warm air (from downsloping westerly winds) before cold air rushes in behind the cold front moving through. Highs push well into the 50s and someone could even touch 60 with enough sunshine. Skies are variably cloudy and I can’t rule out a brief afternoon shower. It’s mostly cloudy and cooler Wednesday night, with lows 33-39 (suburbs-city). A rain or snow shower is possible (20-30 percent chance) towards morning Confidence: Medium
Thursday is mostly cloudy and chilly with a 40 percent chance of rain and/or snow showers as a disturbance swings through the region. With highs 40-44, I’m not concerned about snow accumulation. Partial clearing and seasonably cold Thursday night, with lows 29-34 (suburbs-city). Confidence: Medium
The pattern is definitely a very cold one to start March, Friday through the weekend. The jet stream takes a giant dip allowing Arctic air to dive all the way into Florida. For us, that means highs near 40, and lows 18-26 (suburbs-city). Sky conditions are generally partly cloudy. A little storminess may try to develop off the coast over the weekend, but current indications are too far out to sea to impact us. We’ll keep an eye on it. Confidence: Medium
