According to the Memphis NWS, there is a chance of thundersnow there. So snowfall rates could be of excess of 2-3 inches an hour if that occurs which I believe is likely, there looks to be a lot of lift with the development of this storm atm.
I actually had some thundersnow today :P

I love to be lucky to see thundersnow with this, after experiencing it back in March 2009, It's such an awesome phenomenon and the rumbles of thunder is so LOUD, louder than some of the severe thunderstorms we usually see in Spring.

Birmingham, AL NWS seems to be hinting at a large heavy snow band developing later on during this storm... :thinking:
Quote
NOW ON TO OTHER CONCERNS. OUT OF THE GATE...I HAD BEEN WATCHING
THE DRYING TREND ACROSS THE HEART OF CENTRAL ALABAMA AS MOST
NUMERICAL GUIDANCE DEVELOPS SOME CONVECTION OUT OVER THE GULF
WATERS. THAT SAID...WHEN LOOKING AT THE LOW AND MID LEVEL
FRONTOGENESIS AND NEGATIVE PVU...THERE WILL BE A DECENT BAND OF
MESOSCALE LIFT THAT LOOKS TO FORM NEAR SOUTH CENTRAL MS AND
TRANSLATE RATHER QUICKLY NORTHEAST TO TCL...BHM...AND EVENTUALLY
GADSDEN BY MIDNIGHT OR THEREABOUT. MODEL QPF JUST DOESN`T MATCH
THAT FEATURE...SO HAVE DISCOUNTED SOME OF THE LOWER AMOUNTS BY
KEEPING THE GENERAL 3 TO 6 INCHES WITH LOCALLY MORE ACROSS THE
NORTHERN THIRD OF THE AREA. OF COURSE...THE MESOSCALE DETAILS OF
THIS FEATURE WILL OBVIOUSLY BE DETERMINED IN A MORE NOWCASTING
SCENARIO...BUT I WILL HAVE TO RELY ON THE NUMERICAL OUTPUT FOR THE
GENERAL SYNOPTIC LOOK AND FEEL OF THE SETUP. STILL...THE MOISTURE
WILL BE IN THE ATMOSPHERE...AND IF THE FEATURE IS REAL...THERE
WILL BE THAT OPPORTUNITY EARLY MONDAY MORNING TO SEE A HEAVY SNOW
BAND DEVELOP...WILL BE INTERESTING.[/

There is no watch for Charleston. All rain for that area for most of the storm

I'd love to see thundersnow, too. I don't know why it's hard to think about snow and thunder at the same time...just is! :P

The storm here is just about over. We may get more snow early tonight, but things are starting to quiet down. I will have an update later. :)

Chattanooga is supposed to get about 2-4 inches of snow tonight, 2-4 inches tomorrow, and top the evening off with freezing rain. For the public schools, that's good enough to shut down school for two days. For a private school like mine...I'll be lucky to get tomorrow off.

I'm surprised public schools in your area would react more than private schools. :thinking: Here, public schools would try to find the least possible amount of days to close schools. Private schools couldn't care less, and some don't even have to make the days up. <_<

At least here in Birmingham, the weather people (both the NWS and the local media) are making this sound like it's the end of the world. Like it's doomsday. They are dramatizing this way more than they have to. I don't like it, one bit.  :thumbdown: I hope to get some thundersnow, though. That would be nice.  :D
