The traditional luck of the Irish is in short supply today as mostly gray skies, cool temperatures and late day rain are in the offing. After an unexpectedly mild day on Saturday, when the high reached 61 at both Reagan National and Dulles, temperatures today will likely hover only in the lower 40s.
With a frontal boundary stalled over the VA-NC border, chillier air moving in from the north and a moisture-laden warm front to the south, the potential for wintry precipitation will increase later tonight. We may be on the cusp of spring, but winter will re-assert itself tonight and early tomorrow as Winter Storm Warnings are up for areas to the north and west of the city from 6 PM today until 6 pM on Monday. Especially at higher elevations, 3 to 7 inches of snow and sleet are possible. In the immediate Washington area, only a half inch to perhaps 3 inches of snow, mainly accumulating on grassy areas, is likely. A mix of snow and sleet should continue on Monday morning before all the precipitation changes to rain by afternoon. Lingering showers are possible on Tuesday before somewhat milder temperatures and sunnier skies arrive later in the day.
Even though it will be more gray than green, enjoy your St. Patrick's Day!
