USNA Weather Forecast

Forecast Discussion:

A cold front will approach and pass late Thursday and Friday with rain possible. As the front passes it will likely interact with the remnants of Hurricane Sally to our south, and could pull moisture into the region.  The extent to which rainfall is enhanced remains uncertain. Furthermore, there will likely be a sharp north-south gradient in rainfall totals and 100 miles could make a big difference. The current model consensus suggests 1.0-2.0 inches of rain is possible across Southern Maryland and the lower Delmarva Peninsula while 0.0-0.5 inches seems likely north of I-95.  Behind the front, high pressure will build with seasonably cold temperatures over the weekend..
