.MESOSCALE UPDATE...

...LARGE HAIL THREAT INCREASING IN DULUTH-SUPERIOR METRO AREA...

SUPERCELL THUNDERSTORM NOW MOVING ESE ALONG HIGHWAY 53 TOWARD
HERMANTOWN AND DULUTH.  2 INCH HAIL WAS RECENTLY REPORTED WITH THIS
STORM IN TWIG.  APPENDAGE AND MID LEVEL MESOCCYLONE AREA OF THIS
STORM WILL TRACK ESEWD ALONG HIGHWAY 53 INTO DULUTH IF THIS STORM
MAINTAINS ITS PRESENT MOVEMENT.

THERE IS SOME CONCERN THAT AS THIS STORM CROSS THE LAKE BREEZE FRONT
OVER WEST DULUTH THAT THE UPDRAFT MAY WEAKEN SOMEWHAT.  HOWEVER...
ELEVATED INSTABILITY OVER 3000 J/KG SEEMS TO SUGGEST THAT THIS STORM
WILL HAVE THE POTENTIAL TO PRODUCE AT LEAST GOLFBALL SIZE HAIL IN
HERMANTOWN AND DULUTH OVER THE NEXT HOUR.
