Just a very brief update to keep all informed of the potential of a snowfall for our region of south central PA for early Christmas Day compliments of a relatively weak wave of low pressure riding a boundary northeast and actually evolving into a bona fide nor'easter for New England by Sunday night. This is the scenario as depicted by the European.
First a large high pressure over the "sweet spot" of southern O Canada and New England to supply the cold air. Note the bend in the isobars indicating the weakness of low pressure in the atmosphere to the south of PA through VA and NC. The map below is for 7 pm Christmas Eve.

Then, 24 hours later, the storm begins to crank over the natural baroclinicity of the "warm" Atlantic and the colder land mass. This would be a wet snow scenario as indicated by the 850 mb temps.
Finally, out to the end of next week, the pattern continues to supply interest for snow lovers as a major storm appears to be taking shape and tracking in the classic path of an old fashioned nor'easter. Again, note the high pressure to the north of PA!
That's all....gotta run and do the game between the trinity Shamrocks and the CD Lady Rams! Do you remember those glory days? Maybe coach Randy can bring that type of desire back to CD starting with tonight and a "W" over the Trinity squad!
Have a good mid-week...and I'll keep you posted for the po for a White Christmas!
