I hope the hell not.  You should be fine unless this thing passes over Fredericksburg

I see two competing influences where this storm wants to come north, but at the same time the cold high gets even stronger while bearing down on us. Will be interesting to see how these trend until we're 60-72 hours from game time. By then, the models should be pretty locked in, give or take 15-20 miles

I know you know this, but the 20 mile wide gradient between 2" and 10" makes these storms rough even at close range.

I'm 80-90% confident that there will be a steep gradient in snowfall within a 20 mile range, or even less. I just hope most of us will be on the left side of it.

This could be a season saving storm. Without out we are looking at 2 cutters and no snow by January 15z.

This storm is critical. We could be at above average snow on Monday for the season

It’s like your fantasy rb scoring a td in the first quarter if it happens

We won’t get 2 cutters. Wait and see

As I recall it's rare to get a big one (10"+) before the 2nd half of January. Another reason to be cautious.

Based on history...this sure smells like one of those 1-3" to rain in cities more n & w to me (not trying to be a Deb though). I mean, we are at the beginning of a favorable pattern change...I wonder it it's a tad early for I-95. But hey, maybe I'm just rambling, lol

i would be remiss to not mention this. this is a legit KU level block. 3 sigma at 12 days out is insane

Storms would track NW with the trough in that position though.

This is where it would really get good for the MA as advertised. More mature NA block with lower heights shifting into the 50-50 position, and the Aleutian low is in a better spot with a ridge building towards the western US. If this is real the latter part of Jan is gonna be interesting.

The surface is pretty warm. I doubt I-95 sees accumulating snowfall, but models are holding on

The new Ji…

Rates overcome marginal surface temps as mid levels stay cold enough. Has happened many times before. I-95 gets a mauling of precip, which mitigates that issue. As depicted, that’s heavy snow at 33 degrees, not rain.

It’s not a lock, but if the storm evolves as the GFS depicts, DC to Baltimore would see warning level snowfall with more snow to the WNW.
