.DISCUSSION...
STRONG HIGH PRESSURE WILL REBUILD OVER CENTRAL WYOMING TODAY.
ENOUGH RESIDUAL MOISTURE IN THE LOW LEVELS OF THE ATMOSPHERE
EXISTS FOR ISOLATED THUNDERSTORMS LATE THIS AFTERNOON AND EARLY
EVENING. MID AND UPPER LEVEL DRY AIR MOVING INTO THE AREA THIS
AFTERNOON WILL MAKE IT HARD FOR ANY THUNDERSTORM TO BE LONG LIVED
AND PRODUCE MUCH IN THE WAY OF WETTING RAIN. THE STRONG HIGH
PRESSURE AND MID AND UPPER LEVEL DRY AIR WILL DOMINATE THE WEATHER
OVER CENTRAL WYOMING THURSDAY AND FRIDAY.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
