Accuweather now forecasting a low of -4. That would be a record. Maybe HRRR wasn't too far off. Hopefully, we can get a few more hours of good snow rates, before it finishes up. Officially went from 40 at 5am to 13 at 7am, gusting to near 50mph.
What's the record low wind chill for Pittsburgh? Accuweather has tomorrow's low as -1 and the real feel at that time as -36. That's amazingly cold. Can't find wind chill records though.
HRRR still plunging temps. Down to -8 tomorrow night into 12/24. Wind chill to -32.
Also, HRRR seems aggressive with temps. -6 (a record low) by tomorrow night, and dipping to -7 Christmas Eve (not a record). With so little snow, I doubt that.
Dropped us to under an inch, lol. I don't think it gets to even 1 degree, which is their forecast without more snow on the ground, and if it does, I couldn't imagine how cold it would have been with a couple inches.
I don't buy that Wheeling would have that much more than us, when the changes would essentially be the same just earlier for Wheeling. Maybe just model noise.
If the secondary trends stronger, wouldn't it cause the upper atmosphere to cool quicker for us and allow temps to drop even before the front moves in?
Well, the risk of heavy snow is not far away, and it doesn't discount the possibility of a brief period of heavy snow as the cold air collapses in. I don't think anyone is expecting a foot of heavy snow. It's just saying the risk is there. We'll still likely see some snow, let's just enjoy that possibility.
I guess there's too much going on, they'd have to write a novel. Obviously once these temperatures drop below freezing it's going to snow.
What's weird is TWC has 26 for the Thursday low and NWS has 10. So, that's more of an issue with regard to the flash freeze potential.
