CommuteCast: Increasing Cloudiness
Showers and a chance of snow flakes overnight
After a cold start to the week on Sunday, today featured weather very close to seasonal averages. High temperatures have reached the upper 40s area-wide and winds have been noticeably lighter than recent days. Clouds that began moving in a few hours ago will continue to be on the increase this afternoon and through the evening commute as temperatures fall back through the 40s.
Tonight: A weak Alberta Clipper -- a fast-moving low pressure system from Canada -- will arrive from the west late this evening and pass through the area overnight. Total precipitation is expected to be very light -- many areas may see little more than a passing shower. By midnight, the atmosphere may have cooled enough for any rain showers to change to snow showers. Most towns will not see any accumulation, but a a dusting of snow is possible for some locations. Lows will drop to around or just below 30 in the normally colder suburbs and into the low 30s for the District.
Tomorrow: High pressure will quickly build back into the region on Tuesday. Expect mostly sunny skies and temperatures a touch warmer than today, with highs rising into the low 50s.
