Lol that snow band looks similar to feb 2013
It would have to be constantly heavy for more of the event to be snow. When it lets up the column will warm.With temps being a littler on the cooler side than indicated, will this initial precip help cool the column better and perhaps be useful?
Wow the temperature has really plunged under the current precipitation. Down to 38.5.Temperature definitely dropping a little faster then forecast. Already heading into the 30s and the FFC forecast didn’t have me falling that far for another 2-3 hours.
When I left Acworth it was probable a third sloppy wet flakes and 40.Slowly watching the mping reports from the south crawl north. Seeing sleet and snow mixes in them.
Thats at 6 a.m. Sign me up
Yep, down to 41 here but all rain and will remain so. A good night to read a book by the fire.Wow the temperature has really plunged under the current precipitation. Down to 38.5.
Woah... that’s not bad @ForsythSnowNAM looks slightly to warm from its earlier forecast at 21z at H85View attachment 64056View attachment 64059
The difference between the 3K and Nam were really big that 18z run. 3K was some 3-4 degrees colder aloft than the NAM and much earlier. You mix the thermals from the 3K and the precip from the NAM and you're looking at a much bigger spread of snow further south.NAM looks slightly to warm from its earlier forecast at 21z at H85View attachment 64056View attachment 64059
This has to be a decent signI can definitely say there are some very wet snowflakes occasionally mixing in now.
Yeah the 3km NAM has been fairly consistent with this today showing my part of Union County with around 2 inches and now HRRR is steadily showing it as well. I was wondering if GSP might include us in the WWA but I can see given the potential that it’s a more in the way of localized nature, they’ll probably pull the trigger later if the models stay consistent with it through the night.Worth mentioning wrt backside snow potential:
The exact upper low track is gonna be key here imo and deep-layer cold advection over time will lead to large-scale subsidence area-wide tomorrow evening as the precip changes from rain to snow/sleet, we're gonna need some additional forcing for ascent help to keep generating precip back in the colder air.
Based on the latest 3km NAM & HRRR runs, the strongest differential cyclonic vorticity advection to compensate for sinking from cold advection will be down towards the SC/NC state line, implying a greater potential for backside snow/sleet in areas near the US HWY 74 corridor like Charlotte & Fayetteville vs Raleigh-Durham, at least as things currently stand.
