A COUPLE OF RENEGADE SHRA HAVE MOVED INTO THE WRN PARTS OF CWA.  PLAN
VEIW PROFILER SHOWS SPEED MAX AT H5 AND SFC MOIST CONVG ALONG A
BOUNDARY HAS GIVEN JUST ENOUGH LIFT TO FIRE THEM OFF. BELIEVE SHRA'S
WONT LAST MUCH PAST SUNSET AS THEY LOSE THIER HEATING. CAN HANDLE
SHOWERS IN THE NOW. REMNENTS OF SHRA WILL LEAD TO SOME MID CLOUDS
OVERNIGHT. OTHER THAN THAT LOOK FOR A TEMPS TO FALL QUICKLY OVERNIGHT
WITH DRY AIRMASS IN PLACE.  WINDS WILL STAY UP KEEPING TEMPS FROM
PLUMETTING TOO FAR.  GUID NUMBERS LOOK GOOD AND FEEL NO NEED TO STRAY
FROM THEM.
