Next SW, snow overspreading PA Saturday late afternoon and evening...moved up the speed a tad....but primary is MUCH farther Northwest in the Ohio Valley at this time. It transfers but not great for southeastern PA. Validates the concerns from this AM as to possible eventual depictions.
12Z GFS shows a bit more interaction between the streams for Jan 4th but temps are still an issue...rain in the LSV and snow TV elsewhere in PA. Minor either way.
That was one ugly win. Mike McCarthy thanks the officials.
I still worry about cold coming in for this system ala what the Euro shows. GFS money shot is a thing of beauty though.
Some of the 300+ energy does break off and cut but some of it stays behind in Baja Mexico. This is in the 330's now so not going to dissect any more of that :-)
Snow breaking out again on Jan 9th but this is from a front coming off a Midwest Low so would need a transfer or major block a transfer to stop this from changing over.
This is the 7th not the 8th. Plus temps are still not overly cold. Snowing in the MA (MD, N VA) but 2M temps are above freezing for some of them. Philly near 32, LSV 25-30 during the height of the snow.
HH Gfs Op. Jan 4th SLP is deflected by a GL lows though this scenario does pull some of the colder air of the season into PA with teens and 20's for lows Friday AM.
Prepare to face a Blizzard of info to suggest otherwise! A lot of it is expectations, I think. One can argue we have pattern changes on a weekly basis but blue on those 500H anomaly maps does not always mean surface cold will be BN. I also think some (me included) see the best and have a hard time coming down from it.
