Forecast Discussion: Current conditions: At 2 p.m. EST this Monday afternoon, a large area of low pressure is located over North Carolina, and moving east-northeastward. The storm will move to the Delmarva peninsula tonight and intensify. This will bring strong and gusty north to northeast winds to the area tonight. Precipitation this afternoon into tonight will fall as mostly rain, but higher elevations above 1,500 feet in the western and northern parts of the partnership area can get as much as a few inches of wet snow overnight. Low temperatures will range from near 30 in the higher terrain to the middle 30s in the valley areas. *** Tuesday's forecast: Rain and snow showers will end Tuesday morning, then a little bit of sun is possible in the afternoon. Continued windy with fine particulate levels remaining in the good range. Temperatures will recover into the middle 40s. Partly cloudy and brisk Tuesday night with lows in the middle to upper 20s. *** Extended forecast: A pattern change to colder weather is coming for the end of this week as the general flow shifts into a more northwesterly mode in response to a broad based upper level trough setting up across the northeastern U.S. High pressure will promote a little sunshine on Wednesday, and with less wind, particles may go back to the moderate range. A cold front then moves through with nothing more than a rain shower for Thursday. Clouds and limited sunshine, brisk and cold conditions will follow for Friday into the weekend. Strong mixing in the long range period will promote low levels of fine particulate, and temperatures will average at normal or a little below.---McAuliffe
