Series of weak systems pass through to start work week, storm possible midweek

Some light snow showers and flurries will slowly come to an end this morning over the Capital Region. The cause for the precipitation was a fast moving, moisture starved, clipper low pressure area over southeastern Canada. This system will remain north of the region today, with its cold front passing through the region early Tuesday morning. Precipitation should be a sparse commodity with this feature.

The frontal system begins to slow, and eventually stalls south of the region Tuesday evening. Low pressure is forecast to form along the boundary on during this time, and slowly ride from the Ohio Valley toward the mid Atlantic. Meanwhile, another moisture starved clipper system approaches our region from the northwest, Wednesday morning. As this system passes, a strong high pressure area building into the upper Midwest from the Canadian prairies, will introduce a northerly flow of colder air into the Capital Region.

The southern storm (over the mid Atlantic states by Wednesday afternoon) is forecast to track to a position near Cape Cod by Wednesday evening, and then the Gulf of Maine by early Thursday morning, accelerating and strengthening as it does so. The difference in atmospheric pressure between the deepening low pressure area, and the strong high pressure area building in on Thursday, will help to keep winds elevated and gusty.

Temperatures rebound quickly behind the system, and after a cold start on Friday morning, with high pressure southeast of the region to close out the work week, southwest winds should aid in boosting temperatures to near to slightly below normal levels, perhaps trending back toward normal, over the course of the coming weekend.
