DISCUSSION...KNQA radar imagery has shown a band of 30-35 dBZ precipitation develop and move through western Tennessee. Higher values of KDP aloft suggest heavier snowfall rates are possible which has been corroborated by recent surface reports within the region. This band is expected to continue to the north and east this evening into the overnight. Downstream of this band, temperatures in Middle/eastern Tennessee and eastern Kentucky are still in the 40s to low 50s F. As the shortwave continues into the Mid-South, a deepening surface low development in the central Gulf Coast will support an increase in cold air advection across these areas. This, along with cooling within heavier precipitation bands, will support a relatively quick transition to snow. Frontogenesis at 850-700 mb and ascent with the shortwave will support 1-2 inch per hour snow rates. The greatest rates are most likely along the western foothills/slopes of the Appalachians where upslope flow at low levels will enhance vertical motion .

My buddy in Ruston, Louisiana says it’s snowing at his house .

.

Heavy snow in Jackson per friend .

That gap that’s showing up on most mods in southern middle Tennessee, is that a energy transfer or something? .

I think you are in a great spot .

If it’s moving the same speed as the system wouldn’t that keep it out in front of the moisture return? .

.

Beer, coffee, rinse and repeat .

Also Go Big Orange .

My buddy NE of Jackson Tn has sleet at 34 .

That’s right at 10” over my house in N Knox Co .

I think MRX goes 4-8” in the valley .

I’m not taking my cup off. .

Lol… yeah mine says the same thing .

Are we going to do a observation thread or keep them here? .

.

Well… good point .

I’m really concerned with some of my shrubs for Sunday morning, especially my Jap Maple and Cherry tree. Would 2 or 3 inches of snow on them be enough insulation? Or should I cover them Saturday night, Sunday morning? .

Man that looks a lot like the Canadian for east of the plateau .

That wind is cold. .

.

It’s difficult to say if it will or will not. We rarely see 70 degrees to 25 degrees in 6 hours followed by heavy snow. If this was mostly daytime event I would absolutely agree with you but IMO 25 degrees at night in March is no different than 25 degrees in January but I 100% agree that 25 degrees during the day in March is nothing like 25 degrees during the day in January. I just don’t think we know. .

Where? With a flatter system, a warm layer shouldn’t be a big deal. .

FV3 looked good .
