.DISCUSSION...RAPID DESTABILIZATION OF THE AIRMASS COMBINED WITH
MOISTURE IN A SOUTHWEST FLOW WILL RESULT IN THE POSSIBILITY OF
ISOLATED THUNDERSTORMS LATE THIS MORNING THROUGH EARLY AFTERNOON.
THIS WILL LIKELY BE FOLLOWED BY SOME CLEARING AND INCREASING
SOUTHWEST WIND AHEAD OF AN APPROACHING COLD FRONT. THE COLD FRONT
WILL MOVE THROUGH 1700L-1900L POSSIBLY WITH ANOTHER ROUND OF A FEW
SHOWERS OR THUNDERSTORMS. THESE STORMS WILL BE HIGH-BASED ABOVE A
DRY LAYER OF AIR NEAR THE SURFACE SO THE MAIN HAZARD WILL BE
STRONG ERRATIC DOWNBURST WINDS...ESPECIALLY ALONG THE COLD FRONT.

A COOLER AND MUCH DRIER AIRMASS WILL PREVAIL OVER THE AREA ON
FRIDAY ALONG WITH GUSTY WEST WIND.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
