.DISCUSSION...

...THUNDERSTORMS LIKELY BY AFTERNOON WITH FALLING TEMPERATURES...

AN APPROACHING DISTURBANCE FROM THE WEST WILL RESULT IN A HIGH RISK OF
THUNDERSTORMS ACROSS THE AREA BY THIS AFTERNOON WITH A SLIGHT CHANCE
OF SHOWERS AND THUNDERSTORMS AS EARLY AS 1000L TO 1100L. IT SHOULD
BE MOSTLY CLEAR THROUGH 0900 TO 1000L BEFORE CLOUDS INCREASE AND
SHOWERS AND THUNDERSTORMS START TO FORM. THE HIGHEST LIKELIHOOD FOR
THUNDERSTORMS WILL BE THIS AFTERNOON BUT I CAN`T RULE OUT SOME AS
EARLY AS LATE MORNING. AT THAT ELEVATION...THESE THUNDERSTORMS COULD
EASILY PRODUCE SNOW PELLETS WITH TEMPERATURES DROPPING INTO THE UPPER
30S TO LOWER 40S THIS AFTERNOON. THUNDERSTORMS WILL CONTINUE
AT TIMES INTO THE EVENING.


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