WILL SEND UPDATE AT BOTTOM OF THE HOUR TO FRESHEN ZONES AND REMOVE
MORNING WORDING. REMNANTS OF MCS SPLIT TO TWO GOOD AREAS OF VERY
HEAVY RAIN...IN CENTRAL CWA AND JUST W OF CWA. HIGH WBZ WOULDNT
WARRANT MUCH IN THE WAY OF HAIL...AND DONT THINK THAT SEVERE THREAT
IS THAT GREAT ASIDE FROM AN INDIVIDUAL CELL POPPING. EVEN
HERE...CLOUD SHIELD FROM MCS SHOULD HOLD ANY ADDED INSTABILITY BY
LIMITING OR EVEN CUTTING OFF DIFFERENTIAL HEATING.

MOST OF PM STORMS SHOULD HOLD W OF FCST AREA...BUT AM UNSURE ATTM AS
MESOETA DIDNT DO TOO WELL WITH CONCENTRATION OF PRECIPITATION THIS
MORNING. EXPECT TO TRY AND CUT POPS...BUT DONT KNOW IF THAT WILL BE
POSSIBLE UNDER THIS WIDESPREAD AREA OF SHOWERS AND THUNDERSTORMS.

TEMPS TODAY SHOULD RECOVER RELATIVELY QUICK AFTER RAIN ENDS...BUT
STILL EXPECT TO HEDGE A LITTLE AND CUT A CATEGORY ACROSS THE BOARD
FROM PREVIOUS FCST. GOOD WAA IN PLACE FOR THE REST OF THE DAY.

.ILN...NONE.
