Snow Possible Tonight

Both the GFS and NAM models show some light snow tonight. A coating to about an inch or maybe two, especially north of Philadelphia.

Unlike the “blizzard”, this time the GFS has more QPF than the NAM, which suggests a more likely scenario.

I’m keeping an eye on the Sunday evening time frame. We are flying back to PHL during this period and I’m hoping the expected snow holds off until later in the evening Sunday. There’s uncertainty about the degree of development in this upcoming storm, but there could be several inches by Monday morning.

Away during this wintery week

 

Sorry I’ve been unable to update this weather blog this week.  Away on vacation!

But  looking at the forecast maps, a very active storm pattern is developing, with a sharp upper air trough that becomes negatively tilted early in the week, allowing phasing of energy and allowing a deep coastal low to form off of the Delmarva coast. Likely to bring heavy snow to NJ and possibly Philadelphia Monday through Tuesday.

I’ll have to leave this one to the TV weather people.   My regular blog followers know I’m not keen on the TV forecasters, but Adam Joseph on 6-ABC seems to have the best balance, honesty, and knowledge.
