Penultimate update as our window is nigh; about half of the total for the last run are for this weekend's possible storm, which I had kind of forgot about until yesterday morning when I checked my "trusty" weather app and saw that my snow chances (percent) for next weekend were higher than either today/tomorrow or Thursday.

The TPV (as represented by GFSv16) continues to accelerate south/southeast and begins (continues?) to influence our favorite anomaly. Based on the movement of the TPV one would think we are looking at different times but no all of the plots below are from 7 AM on the 28th -

What's nice about the Para is that it has an expansive region of snow compared to its preceding 2 runs. Pushes solid snow amounts east to the coast and north -

I feel your pain. To the best of my recollection, I haven't experienced a 2" storm in my backyard since January 2016. I was on vacation during the March (spring training) and January (Tucson trip following AMS meeting) events we had during the last several years.

I've bottomed out at 23 degrees - at least that's the lowest I've seen. don't have a max/min. The 00 EPS does show below normal high temperatures for a 9 day period beginning next Saturday. -

The 00UT EPS still have numerous good hits in the 8-11 day range. The downside is that most of the ensemble members delay the start of any event until next Tuesday - about 24 hours later than the ensembles showed 2 days ago. For College Park, 1/3 of the members are snowless while 1/5 predict a MECS or BECS resulting in an impressive snow mean of 6-7" and a median of 4" Hopefully, we won't end up getting the mode.
