A COLD MONDAY ON TAP ! SNOW & RAIN FOR TUESDAY.

Another cold day is on tap for the Delaware Valley. Temperatures will struggle to reach 30 Degrees Today, but we can expect Mostly Sunny Skies. Tonight Clear and Cold weather continues with Clouds increasing Late. Low will be in the mid to Upper Teens. On Tuesday a Weak area of low pressure will move across the G/L and into Northern new England Tuesday night.

A Very Strong Cold Front associated with this storm, will approach on Tuesday. Skies will become Cloudy and some Snow or Mixed Snow and Rain will develop, during the late morning hours. A southerly flow ahead of the front and WAA (Warm Air Advection), should bring in just enough milder air, to change this snow or mixed precip to Rain during the afternoon, especially, south and east of PHL.

Behind this front some Rain/Snow showers can be expected for Tuesday Evening, as temperatures drop into the 20's, and winds begin to increase. Some light snow Accumulations are possible, for Tuesday into Tuesday Night, But surface temperatures of 35 to 40 Degrees, and Mixed with Rain, will make it difficult for any Accumulations. I'll have more on this system tonight along with a detailed forecast.
