.DISCUSSION...
SFC FRONT CONTINUES TO BE CLOSE TO THE AREA. THINK IT HAS
RETROGRADED A BIT WESTWARD AND IS NOW JUST CLIPPING OUR NORTHWEST
COUNTIES. ELSEWHERE...TEMPS HAVE SKYROCKETED TO AROUND 70...MUCH
WARMER THAN ORIGINALLY ANTICIPATED...AS CLOUDS RAPIDLY BROKE UP.

WITH THE WARMER TEMPS COMES MORE INSTABILITY...AND A SEVERE TSTM
WATCH HAS BEEN ISSUED FOR THE ENTIRE HUN CWFA. NORTH OF THE
FRONT...THE MAIN THREAT WILL BE FOR LARGE HAIL. SOUTH OF THE
FRONT...THE THREATS WILL BE FOR SMALL TO MARGINALLY LARGE HAIL...
AND GUSTY TO DAMAGING WINDS. AN ISOLATED TORNADO CANT BE RULED OUT.

STILL...DO NOT THINK THE THREAT IS TREMENDOUS FOR SEVERE WX BUT
PROBABLY THE THREAT IS SLIGHTLY HIGHER THAN WITH THE LAST SYSTEM
GIVEN THE ADDED SUNSHINE.

FLOOD THREAT REMAINS MARGINAL.
