@Eskimo Joe We are closed off at the mid levels, looks like 850 and 925 we're seeing closed circulations. Looks like they'll make a decent pass for us this evening.
I think there will be some pretty good dynamics around and a relatively good h85 pass this evening if we can get the column right to tack on a few inches of powder.
Hr 9 of the 21z HRRR has a nice band of moderate to heavy snow covering HGR-FDK-DMW. Would probably produce pretty good ratios in that band since the dynamics on the sounding are relatively impressive
+SN continues in Westminster at 27 degrees. Up to around 6” so far. Thinking if we can hold off the sleet for another 2 hours we’ll crack 10 for the storm, especially if we tack on any extra tonight.
Here’s the best place to be the next 2 hours. I think the mix line will go just south of Westminster and just N of Frederick down the corridor between 81 & 340.
Can report ++SN and 27 in Westminster. Around 4” OTG. Larger flakes mixed in with smaller flakes. A bit gusty at times as well. Probably bordering on 2”/hr rates.
The best is yet to come for us. I’m betting there will be an hour or two we pick up 2” in that hour. Fronto continues to increase so the rates will be money from 3-5 if we can hold on to all snow.
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.
