Computer guidance for the last several days has been hinting at a potential for a storm system this week...and in some cases, hinting at two storm systems -- one on Wednesday into Thursday and the other on Friday into Saturday. There's been a good deal of uncertainty over which of the two storm systems would be the bigger/stronger of the two - whether it would be the midweek system or a potential storm on April Fools' Day. The stronger April Fools storm would require a weaker midweek storm while a stronger midweek storm may limit the potential for the April Fools system to pop up.
As of this afternoon's guidance, we're still up in the air in terms of which storm ultimately ends up stronger but it does look like we're going to have two events to track this week. It's not a certainty but there is relative agreement from the GFS and Euro around a storm tracking to the south of Philadelphia during Wednesday evening and night. The Euro (below) is a stronger storm of the two and is showing a mixed bag of precipitation -- temperatures at the magic 5000' level would be cold enough for snow but temperatures show enough moderation in temperature in the atmosphere to make this a less snowy situation.
The GFS (below) is weaker and warmer, with precipitation much lighter than on the Euro and the storm system generally a light rain maker for Wednesday night and early Thursday. The GFS' more minor presentation of this storm helps prop up a bit of a stronger storm on Friday night for the East Coast than toady's Euro. Both models bring a chance of either rain or snow for Friday night, with the GFS bringing a bit more moisture in this storm -- it's not a full blown coastal storm like some past runs of the model (and the Euro) have shown but it does still hold onto the second system potential.
The week at large continues to suggest below average temperatures and a cool regime holding in the East into early April.
