Wintry Feb. 19-20

Interesting.. just like how that Baja cutoff screwed us with the Jan storm in the closing days. This one may end up helping us.
After the January storm, I said I wasn’t going to get sucked in again this year… Well here I am.

This is something I picked up on as well. That piece of energy speeding up in PNW is very interesting and something to keep an eye on in future runs.
 
Yeah and with the ukie being more amped and inland, it gives me a slight pause. I've been and remain cautiously optimistic but refrain from full on excitement until it's still trending/showing this tomorrow at 12z
agree, it's about the only red flag still. That said it's not that far off from adjusting to euro...or gads--euro moving towards it. :(
 
The EPS showed just over an inch of QPF for this event for Wake County. If this were snow we would be looking at a foot or more. If this is freezing rain an accumulation of around 1/2 inch would be a good guess with temperatures in the twenties for the entire event. Temperatures will struggle to get to the freezing mark for up to 48 hours after the storm is over. Fun times!
 
Is the Atl area out of the mix for this one ?
For the NGA folk we know to not underestimate wedge power, but also that wedge will often erode quicker than desired. Someone smarter than me can weigh in on specifics for this storm. Recent runs are wedge happy though.
 
This winter has taught us to respect patterns like this with big chunks of the northern stream getting trapped underneath persistent blocking highs. Oftentimes, when this pattern rears its head, we don’t get last second north trends.

This storm is yet another reminder of that
Welcome back and I'd guess your thoughts are it may tick a little further south? Seems very plausible considering the blocking

There’s no reason to think it can’t happen. The shorter wavelengths at this time of the year means we get more amplified storms, so we pay a bigger price for little errors like this

Welcome back Eric!! Know you have been busy with the weather in NM!

I do wonder how much better this could actually trend. I wonder what the cap on better trends could be in this situation. CAD is a tough cookie to figure out.
Model guidance will struggle at this lead because the climo norm boundaries are being pushed. We are in the 95-99th percentile in strength at this point.

In other words, expect colder and colder. I'm not a fan imby.
 
8" mean on the EPS imby and across the northern counties of NC, if this fails us again it's evil, just diabolical

Any chance you’ve got the actual members for Say Statesville ? Just to see if it’s skewed or actually more volume of larger hits?

The ultimate question for next week is how far south our cold source gets pulled from our ongoing storm. The trend has been for a stronger connection, and thus winter weather further south into the Carolinas.

I think I-85 N is 70% locked in for something frozen. Areas further south could join the action, but higher uncertainty currently.

I do not but 1300 just posted those in gif format the immediate post before yours.
 
I can definitely see us getting a Feb 17-19 1989-type storm here in the Carolinas. Good to see that analog generally panned out this month with exceptional volatility and a shift towards more wintry weather mid to late month
Could CAE possibly see something wintry too? Seem like shift was to the south?towards Midlands.
 
This winter has beaten it into our heads that when you see a big block trap a cold northern stream trough underneath, it’s just not a good recipe for a sudden northward shift.

Outside of Nino winters when your southern stream is much more amplified, you usually need the blocking to back off for the mid Atlantic and NE US to score
 
Anyone have the Pickens sc airport individual ensembles from euro? I’m guessing 3/4th show something

Thinking the same thing.
Go back to the last storm in late Jan.
We were hoping for the NW trend that never came.
Patterns repeat maybe this is our Gulf coast storm in late Jan.

It looks like to me like the 12z Euro Graphcast and Pangu are getting the snow line down close to columbia. Gonna need bouncycorn to show up with those pangu ensemble spread maps again. IIRC, they did pretty good with the early January event nailing down p-types.

12z Euro AI is also south and colder, but pretty paltry with precip totals.

Not much liquid at all with it
