.DISCUSSION...WINDS WILL BE THE BIGGEST CHALLENGE THIS AFTERNOON AS WINDS ALOFT
VARY WIDELY OVER THE COURSE OF THE DAY AS A CENTER OF HIGH PRESSURE TRANSITIONS
OVER THE AREA. WITH OVERALL WIND SPEEDS RELATIVELY LIGHT ALOFT...THERE SHOULD BE
MINIMAL IMPACT ON THE LOWER LEVEL WINDS...SO EXPECT TOPOGRAPHIC FEATURES
TO BE THE DOMINANT FACTOR...GOING WITH A WEAK UPSLOPE WIND DURING THE DAY...
TRANSITIONING TO A DOWNSLOPE WIND IN THE EVENING. THERE IS STILL AN OUTSIDE CHANCE
THUNDERSTORM DEVELOPMENT DURING THE MID/LATE AFTERNOON...BUT CHANCES ARE MINIMAL.
ADDITIONAL MOISTURE WILL ADVECT ACROSS THE REGION TODAY THROUGH SUNDAY...SO CHANCES
FOR THUNDERSTORMS ARE EXPECTED TO INCREASE EACH DAY.
