PROGRESSIVE/GENERALLY ZONAL UPPER-LEVEL FLOW WILL PREVAIL OVER THE

COASTAL PORTIONS OF WASHINGTON. EAST OF THE ROCKIES, SURFACE HIGH
PRESSURE AND CONTINENTAL TRAJECTORIES WILL BE PREVALENT WITH
ESSENTIALLY NIL THUNDERSTORM POTENTIAL. GRADUAL AIR MASS
MODIFICATION AND LOW-LEVEL MOISTENING WILL OCCUR OVER THE WESTERN

CURRENTLY EXPECTED TO PRECLUDE THUNDERSTORMS ALONG THE TEXAS COAST.
