Did the SREF have a late blooming low? I would guess we will see ups and downs over the next 24 hours.- 847 replies

The RGEM has scored several wins before, usually related to northern stream events. These anafrontal low spin ups are rare these days but used to be a common way to get 3 to 5 inches imby.- 847 replies

After looking I think the MRX grids were likely generated off the 48hr 18z HRRR. That is definitely the inhouse model I just saw WVLT run. It was literally the exact depiction from the HRRR for Thursday. Which suggests very little in the way of snow but the HRRR at 48 is like looking at the GFS at 300.- 847 replies

GFS backed down a bit from 12z. Runs will vary from here on out, especially as they are about to leave the global wheelhouse and be more in line with the meso model time frame.- 847 replies

The point forecast at 2500 feet here says less than 1/2 inch of snow possible. For downtown Knoxville it says less than 1 inch possible. No idea how they are seeing the grids unless it's a UKIE/Euro blend.- 847 replies

I'd guess tomorrow morning if the models don't lose it, they will issue winter products for the mountains and SWVA. SPS for other areas. I got 4 inches in 4 hours last December and never even got a WWA. Knox got at least 2 and didn't either. They are always very reluctant with WWP outside the mountains and it often works out for them but sometimes doesn't.- 847 replies

I don't remember if we've had one in the last several years. The models have had multiple upgrades since then so I'm not sure how they may handle it now.- 847 replies

That's the fingers! The models won't place them in the same area two runs in a row but totals will be heavier under them.- 847 replies

RGEM is probably the model we most want to see come true at this point. Larger snow shield and the 2nd spoke of energy just keeps snow showers around for a long while, especially souhern middle areas.- 847 replies

The NAM is still showing the accumulation fingers to some extent and they aren't elevation driven. This run the finger of lighter snow goes from Crossville to Jamestown, two of the 10 snowiest towns in the state.- 847 replies

Speaking from experience, being in the bullseye across most modeling for a week straight virtually never works out for me. That's where I've been on almost every model run except the last couple of Euro and UK runs for about 8 days, this event hit the GFS at 228 hours. Don't know if it will be right but except for yesterday it's been rock steady.- 847 replies

It's epic cold in Russia. If we get the slightest cooperation from the Pacific and gun cross polar flow between that -NAO and a +PNA we'd all need the vodka too. -

It basically bounced back to its runs leading up to today. Still progressive in getting everything out early. It may be missing some upslope and general snow showers that arctic air squeezes out. Still a good run for the east half of the area.- 847 replies
