I’m starting to be more of a believer in that band/swath. It definitely has the potential to tack on several inches as the column quickly cools and dendrite production is top notch.
I’d estimate visibility between1/8 & 1/4mi in Westminster with swirling flakes growing in size. Rates probably 1.25-1.5”/hr with the wall of yellows moving in.
I should also note winds still out of the NNE/NE at the moment. You can even tell with the slightest bit of subsidence as the good returns move over us with them taking their time.
I think we can really pile it up the next 5-6 hours and I’m willing to bet our column holds. There’s going to be 1-2” an hour rates with some places even besting that through 6PM.
I’m thinking somewhere in between. The heavy rates are overcoming the warm nose at the moment all the way into ROA. Mesoanalysis running right on tap it not a bit colder than predicted at the mid levels, with surface temps running a degree or two below.
Starting to stack up outside Westminster. Like Joe said, pay attention to the 700-850mb fronto page on SPC meso. If that verifies some of the maps Millville was talking about, it’ll be an electrifying afternoon for rates in a lot of spots.
Lots of folks gotta love the HRRR for this afternoon. Basically 1-2” an hour rates north of the beltway into C MD and NW.
fronto is increasing in the area and the low is starting to deepen off the NC/SC coast.
Snowing pretty good in Westminster, most things covered. 140 wasn’t too bad moments ago, side roads mainly covered already so could be a little slick.
27 degrees
I actually like the meso obs from SPC right now. Checking the various levels of temps and coupling that with obs in forum make me believe the HRRR won’t be completely out to lunch. The NAM, on the other hand, looks like it was off by quite a bit.
Where’s @MillvilleWx, I’ll repost what he said overnight for us folks in the northern counties:
“I'm gonna say it now. Someone north of I-70 between 20-00z is gonna see some absolutely insane snowfall. The 85H frontogen is beyond incredible for that area during that timeframe. This reminds me of some of the surprise overperformers in recent past with front end thumps.”
