DISCUSSION
MID AND HIGH LEVEL CLOUDS TODAY WILL PROVIDE SOME
SHADING AND HELP KEEP TEMPERATURES DOWN NEAR SEASONAL AVERAGES
THIS AFTERNOON. A DRY AIR MASS AND COLD TEMPERATURES HAS CAUSED
DEW POINTS TO DROP INTO THE UPPER 20S, BUT DESPITE THE DRY AIR,
THE COOLER TEMPERATURES TODAY WILL HELP TO KEEP THE HUMIDITY IN
THE UPPER 20S AND LOW 30S. WINDS TODAY WILL BE LIGHT AND VARIABLE
UNDER STABLE CONDITIONS CAUSING POOR VENTILATION. A SHORTWAVE
TROUGH MONDAY WILL CAUSE INCREASED WINDS, A DEEPER MIXING HEIGHT,
AND BETTER VENTILATION.
