December 1 2012 Storm chances??

[obwan]

Storm prediction centre has some slght risk for storms for SW Ontario this afternoon and evening.

...GREAT LAKES INTO OH VALLEY...

THE RESPONSE TO A LEAD SHORTWAVE TROUGH TRACKING FROM THE NRN/CNTRL
PLAINS THROUGH THE GREAT LAKES AND MID MS VALLEY WILL RESULT IN THE
BROADENING AND STRENGTHENING OF A SWLY LLJ FROM THE OZARK PLATEAU
INTO THE GREAT LAKES. THIS FEATURE WILL HASTEN THE NWD FLUX OF
LOW-LEVEL HEAT AND MOISTURE BENEATH GRADUALLY STEEPENING MIDLEVEL
LAPSE RATES...YIELDING A WEAKLY UNSTABLE ENVIRONMENT FOR PARCELS
ROOTED IN THE 900-850-MB LAYER. THE COUPLING OF DCVA ATTENDANT TO
THE SHORTWAVE TROUGH AND LOW-LEVEL WAA/ISENTROPIC ASCENT ALONG THE
LLJ WILL FOSTER ISOLATED TO WIDELY SCATTERED ELEVATED TSTMS THIS
EVENING INTO TONIGHT FROM SERN WI AND LOWER MI INTO PARTS OF THE OH
VALLEY. NO SEVERE WEATHER IS EXPECTED.

Hmm... E.C. forecast has the temps between 10-13C here in St. Kitts over the next few days, so maybe a warm front pushing in could trigger something. December tstorms are usually weak but definitely better than nothing!

Didn't hear any thunder last night, but USPLN had numerous lightning occurrences over Huron and Bruce Counties before I went to bed @ 2am. Twitter was also somewhat teeming with reports of thundershowers and even strong winds. Hm.
