Absolute Vorticity

Snow just started here

.75" here. No surprises so far

My 8pm obs: 28 / 25 with snow. Still not sticking to any pavement. 1.5" now on the grass. Per radar my 2" is a lock and I wonder if a run at 3" is now within reach?

Little Rock Mets called for a dusting and they wound up getting 2-3"

1 mile vis at CVG Total QPF so far 0.07"

Looking at traffic cams, interstates looked wet so far around the area. Looked pretty in the lights seeing the snow falling and snow in the grassy areas and medians.

It is days like today that make me love weather! I recorded a high of 55 at 12:37pm. Currently 28 with light snow. A 27 degree drop in a short time.

A 1" report out of Blue Ash as of 8:30pm into ILN.

Matt... you should have some nice flakes down there!

Hello from Ross

More reports as of 9pm... 1.2" Delhi Township 1" at ILN and 1" at South Lebanon.

LOL! I wish you were here for this one, Tim! Ugh... I mean you're not missing out on a monster system. You would have rushed up here for that! This is such a pretty snow and probably little to no shoveling involved. The perfect kind of storm.

Tomorrow... we will be tracking snow showers off of Lake Michigan and also in cyclonic flow behind the strengthening low over interior New England. Should be an interesting day watching snow squalls. These will be more random but I hope to catch a couple of them We've all got about the same chance.

Well, the radar has been lit up over my hood for quite a while now and just barely a few flakes are coming down.

SE Crew Zone getting hammered as expected tonight... enjoy it Matt! Then for the rest of us, we've got a lovely band of our own moving in that could dump an additional 1/2" plus in spots. I think the forecast is on track.

An inch of snow in Batavia now as of 9:19pm.

Areas affected...Portions of Tennessee and Ohio River Valleys

Concerning...Heavy snow

Valid 120224Z - 120730Z

SUMMARY...Heavy snow in western portions of Tennessee and Kentucky
will continue north and east this evening and into the overnight.
Rapid cooling ahead of this activity will support a quick change to
snow. Rates of 1-2 inches per hour are possible, particularly in
areas of terrain enhancement.

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.

3-4"... if you can get into that category it's a huge win for the forecast. Keep us posted.

Blizzard warnings issued for the Blue Ridge Mts of West WV. Nashville WFO expanding their winter storm warnings. Several 4" report into Little Rock NWS Office.

Awesome Jeff! I would assume a brief period of lake effect tomorrow for you on the backside?
