I know this is waay to soon, but check out the long range GFS. Might be something in the works?

Monster Snowstorm? 12/23

Just checked the lightning data... Central IN has had a few strikes in the past half hour, and the WV loop really exploded with moisture over that region... It looks like a heavy convective snow band is trying to organize. Various models indicate very weak symmetric stability, and possibly convectively unstable (theta surfaces folding in on the cross sections), also a nice TROWAL setting up between 600-500mb across IN/MI. All of this is put into reality with the help of some strong frontogenesis and omega through that layer as well...
Over all, looks like Ohio won this one!

I agree....looking interesting.

Looks like Dayton has passed up the Blizzard of January 27-28, 1978 snowfall amount...
This system has produced a TON of snow, with a wide area receiving over 16 inches... While these amounts likely match, or possibly exceed the Blizzard of '78, the winds have certainly been kept to a minimum (Blizzard of '78 had gusts of 100mph combined with the snow)...

Man, now that would be crazy!!
Update from NW IL. I can see the moon barely through the high overcast. The ground is bare, but frozen. It's so weird that it's very cold out and yet no snow on the ground.

Well we've only got about 4" of snow total from the storm. On top of that theres about 1/4-1/2 an inch of ice so far. The trees look pretty cool hanging down but I'd rather have two feet of snow like SW/C Ohio are getting. :x

Well, it's almost the end of the line for the snow here, and we I got about 9 inches on the ground...
My original forecast had the heaviest snow centered on northwest OH and southeastern lower MI, as well as parts of IN... It looks like the amounts I predicted pretty much verified, but I was too far northwest by about 50 miles (but then again, that could have been incluenced by wishcasting, LOL)...Since the Blizzard of 78 was mentioned, here is a surface map from 12Z 26 January 1978 as the low moved into southern Canada. Lots of lines on that map.

What was cool about that 26 Jan 78 snowstorm was the "slingshot" of arctic air that cut through IL/IN/OH. These areas were already in the cold sector, and as the low deepened in the Appalachians, a fresh arctic air mass in Iowa accelerated eastward. Around midnight in Indianapolis, Cleveland, etc, it went from light winds and 35-40F to 10F with a 40-50 mph wind raging out of the west. Just one hour later. The suddenness of it was what was so amazing.
By the map time above (12Z) it was already banked up against the Appalachians and not so well-defined. But boy, those 06Z maps are impressive. The squirrely temperature regime along the MI/OH border and the IL/WI border gives some idea though of how strong and localized the arctic blast was.

Liberty Indiana just south of Richmond and west of Dayton is king of the hill currently with 31 " recorded.

Central Arkansas received a decent amount of snow from the system (12/22). My elevated location in Little Rock picked up about 4 inches of snow. The wind was awful with gusts to 30-40mph, which created areas of large snow drifts. Currently travel is very hazardous to near impossible in the hilly terrain of West Little Rock. Thought I would share an image of the pretty sights. Take care and Merry Christmas!

I'm going to archive all of the data for this event -- NEXRAD, satellite, lightning data, surface/upper air obs, and model output from the big 3 (RUC, ETA, GFS). It will be interesting to review the data, especially now that it is known where the heaviest snowband setup, and see what meteorological features really played a role (TROWAL, frontogenesis, slantwise convection).

We got about a foot or so here in Greenwood, with snow emergencys declared over most central indiana counties this morning. The drifting made things a lot worse. It was lots of fun digging out.

Snow is everywhere. Lots of snow here; a good standard all over the yard is about a foot, with 2 and 3 foot drifts varying in size. Very nice.
I had to chip off ice and snow from the bottom of my pants, and see if I can get the frozen things off. Imagine soaking about a foot of the bottom of your pants, then putting them in the freezer; with snow packed between the jeans and boots. Fun.Mike Smith
Here is the status of the storm at around 11pm yesterday evening from our SelectWarn® display. The snow depths are from National Weather Service Local Storm Reports (LSR's) and the red data are selected remarks from those LSR's. Note the dot denoting a cloud to ground lightning bolt northwest of the report of thundersnow to the north.
The 24 inches displayed on this image was at the town of Scottsburg, IN which ended up with 29 inches!
Merry Christmas!!
