WILL ISSUE UPDATED ZONES NOW DUE TO RAPIDLY ADVANCING STRONG
THUNDERSTORM ACTIVITY MOVING TOWARD OUR FORECAST AREA (GOLF BALL SIZE
HAIL REPORTED JUST NORTH OF LONDON ONTARIO LAST 1/2 HOUR...THANKS TO
OUR CANADIAN COUNTERPARTS AT TORONTO FOR HEADS UP PHONE
COORDINATION). EXPECT TO GO INTO A SEVERE WEATHER MODE SOON SO
RESOURCES WILL BE DEDICATED TO MONITORING THUNDERSTORM ACTIVITY.

THIS HAS BEEN AN ALMOST TEXTBOOK EXAMPLE OF A LOADED GUN ATMOSPHERE
OUT TO THE WEST OF US THIS EVENING.  THE 12Z ETA MODEL SOUNDINGS
SHOWED A GOOD MID LEVEL CAP THROUGH EARLY EVENING THAT WAS FORECAST
TO BREAK AROUND 8PM BASED ON THE DTX FORECAST.  WELL, THE ACTIVITY
DID EXPLODE ONLY ABOUT AN HOUR EARLIER THAN THE FORECAST SOUNDINGS
SUGGESTED.  I WAS AMAZED TO SEE HOW WELL THE SOUNDINGS SUGGESTED THE
BREAKING CAP.  THIS IS A GOOD EXAMPLE ON HOW BETTER TEMPORAL AND
SPATIAL RESOLUTION OF FORECAST SOUNDINGS CAN FINE TUNE THE PREDICTION
OF SEVRE WEATHER OUTBREAKS.  IN ADDITION, I RAN THE CONVECTIVE
ANIMATION DISPLAY ON BUFKIT AND THE DTX SOUNDING WHICH SHOWS STRONG
LOW LEVEL SHEAR AND EXCELLENT CAPES SHOWS SPLITTING AND POTENTIAL
RIGHT MOVING SUPERCELLS THAT MATCH UP PRETTY WELL WITH WHAT IS
CURRENTLY OCCURRING.

THE PROGRESSION OF THE CONVECTION WILL BE A VERY TOUGH CALL AS IT
APPROACHES OUR FORECAST AREA BECAUSE THESE CELLS ARE RUNNING ALONG
THE ENTIRE LENGTH OF 32 DEGREE LAKE ERIE.  EVEN THOUGH THE CELLS ARE
PROBABLY BEING FORCED BY THE UPPER LEVEL JET I CANT HELP BUT THINK
THAT THE LOW LEVEL COLD AIR WILL HELP TO CHOKE ACTIVITY A BIT.
HOWEVER, THAT DOES NOT APPEAR TO BE HAPPENING.  THE DYNAMICS ARE JUST
TOO STRONG.

WE WILL MONITOR THE SITUATION CLOSELY...ZONES WILL BE ISSUED SOON.
