@Jacob_Feuer I mean, people at this point know about 2/5% tors on the EC (unfortunately)

[Rob Reale @keepinit_reale]

@CameronJNixon The south is moistttt

[SRRadarLoops @LoopsSr]

#SRRadarLoop of the Kankakee IL EF3 tornado. This tornado tracked for 36 miles and just over a half mile wide. Peak winds were 150 mph.

[Rob Reale @keepinit_reale]

@MananMathur21 Max snow could be a touch north which coincides with best lift / soundings. Also, further south you go, mixing is a slightlyyy higher concern

[Rob Reale @keepinit_reale]

This does actually extend into MD, likely just north of DC with a stripe of decent snowfall. However, it's largely afternoon. So while there may be a "surprise" 1 or 2" locally (currently no NWS snow thru Mon eve), it won't really do much on pavement so not big deal.

[Rob Reale @keepinit_reale]

Classic "weak wave" set up late tonight - Mon AM thru the OH Val. Follow the upper level forcing and fronto, generally on the northern side of QPF gradient. Expect higher totals than NWS forecasted, on northern side of where current max forecasted. AM rush implications

@clarencewlsmith @ameliaUrquhart_ Lol should have guessed. Thanks!

There’s a hundred of these views posted on X already. This is 101, just because this storm deserves it. #blizzard
6 hour loop ending at 9:50 est.

[Sam Brandt @sambrandt99]

There was much discussion about subsidence zones on the colder (WNW) side of snowbands during the recent blizzard. But you may still be wondering "why does it occur on that side of the band specifically?" Well, the answer has to do with the dynamics of frontogenesis:

Mets & WeatherNuts will appreciate this loop.

Blizzard 2026 Radar, 500mb and MSLP loop.

Watch that Upper low come barreling down and stack itself over the Low that exited North Carolina

White Outline = Mesoscale Disco for heavy snow rates

[Rob Reale @keepinit_reale]

Low level moisture hung around with a light NE wind, thus no clearing, thus no radiation cooling. Had the ingredients, but not the right set up

[Rob Reale @keepinit_reale]

While this snow event will largely have minimal pavement impacts, especially S of 78, its possible post-event is the greater concern for black ice.

Air temps are cold, grounds cooler side, and will be plenty wet. Will come down to cloud cover / rad cooling

[Rob Reale @keepinit_reale]

This is actually insane

[Rob Reale @keepinit_reale]

Between MA and RI, this is possibly the craziest inverted trough / Norlun set up you may ever see if your lifetime. You don't get to say that very often

[Rob Reale @keepinit_reale]

I'd have to look more into it, but I wonder if there has ever been an arctic front that met up with a norlun and will the rates reach over 4"/hr in spots because of it?

[Rob Reale @keepinit_reale]

Woof so far. 12"+ coming

[Rob Reale @keepinit_reale]

Norluns be norluning

[Rob Reale @keepinit_reale]

@burgwx I found Dec 20-21, 2024 to be an decent recent analog (NYC to ABE area) to the invteted trough / sounding aspect, which verified 20:1 on NW NJ. Lower urban areas due to marginal temps that go around. Plus, the bonus of extra meso enhancement this time with norlun / arctic front
