.DISCUSSION...
A DRY WESTERLY FLOW WILL STRENGTHEN ON THURSDAY THEN CONTINUE ON
FRIDAY AS ENERGY MOVES ACROSS THE NORTHERN TIER STATES. WESTERLY
WINDS ARE EXPECTED TO MIX DOWN TO THE SURFACE EACH AFTERNOON...
WITH BREEZY CONDITIONS DEVELOPING. IT IS LIKELY THAT THE TERRAIN
MAY AGAIN ACT TO MODIFY THE WIND DIRECTION TO SOUTHWEST AT TIMES
DURING THE AFTERNOONS. MIXING WILL QUICKLY SUBSIDE AS THE SUN SETS
AND THE SURFACE LAYER DECOUPLES FROM THE FLOW ALOFT. LOOK FOR
TEMPERATURES A TAD COOLER ON FRIDAY.
