I don't want to keep taking up our local thread...thunder snow has to be one of the coolest things in the world to experience because snow is so quiet falling.

I was in a "thundersnow" for the blizzard of 1993, while living in Montgomery. I didn't realize until years later, just how rare of an occurrence it actually is.

My poor co-workers in Buffalo, I get a feeling that they are already looking into their calendar for January-March in planning a Florida market visit, good excuse to get away from their cold brutal winter and expense it to the Co, lol.
By the way, I have spend 5 days at the end of January, hopefully lake Erie would be frozen up by then.
MESOSCALE DISCUSSION 1928 NWS STORM PREDICTION CENTER NORMAN OK 0814 AM CST THU NOV 20 2014
AREAS AFFECTED...LEE OF LAKE ERIE AND LAKE ONTARIO
CONCERNING...HEAVY SNOW
VALID 201414Z - 201845Z
SUMMARY...SNOWFALL RATES /EXCEEDING 2 INCHES PER HOUR/ AND THE POTENTIAL FOR THUNDERSNOW ARE EXPECTED TO INCREASE BY MIDDAY IN LEE OF LAKES ERIE AND ONTARIO AND PERSIST THROUGH THE AFTERNOON.
DISCUSSION...TRENDS IN SOUNDINGS /INCREASING HEIGHT OF THE INVERSION ACROSS LOWER MI BETWEEN 00Z AND 12Z TODAY/ ARE INDICATIVE OF THE COOLING TEMPERATURES AND HEIGHT FALLS SPREADING EWD WITH THE APPROACH OF THE UPPER GREAT LAKES MID-LEVEL TROUGH. 12Z SOUNDING AT BUF SHOWED SIMILAR TRENDS IN THE LOW-LEVEL LAPSE RATES...AND THIS TREND WILL CONTINUE AS THE COLDER AIR SPREADS EWD ACROSS THE RELATIVELY WARMER LOWER GREAT LAKES TODAY. FORECAST SOUNDINGS PER 12Z RAP/HRRR OVER AND EAST OF THE LOWER GREAT LAKES CONFIRM THESE OBSERVATIONS WITH AN INCREASE IN BUOYANCY. THUS...THE INCREASE IN CONVECTIVE DEPTH SHOULD RESULT IN THE POTENTIAL FOR THUNDERSNOW EMBEDDED WITHIN THE ONGOING BANDS...FURTHER ENHANCING THE HEAVY SNOWFALL RATES.
Want to see snow? Head west towards southern California, Las Vegas and Arizona. Winter Storm Warnings are up for that area for tomorrow night into New Year's Eve.
