.DISCUSSION...
HIGH PRESSURE OVER TEXAS AND LOW PRESSURE TO THE WEST WILL BRING
TROPICAL MOISTURE UP FROM THE SOUTH. THE VERY MOIST AIR AND WEAK
DISTURBANCES ALOFT WILL CAUSE SHOWERS AND THUNDERSTORMS ACROSS
THE AREA TODAY INTO TONIGHT WITH THE CHANCE OF LOCALLY HEAVY
RAIN. HUMIDITY RATHER HIGH TODAY AND TONIGHT WITH AFTERNOON
TEMPERATURES NEAR NORMAL. HUMIDITY GENERALLY IN THE 40S AND 50S
THIS AFTERNOON AND IN THE 80 TO 90 PERCENT RANGE TONIGHT. THAT
HIGH PRESSURE WILL WEAKEN OVER TEXAS AND REDEVELOP FARTHER WEST
OVER ARIZONA AND UTAH TOMORROW AND THURSDAY. THIS WILL PUSH THE
PLUME OF TROPICAL MOISTURE TO OUR EAST AND REDUCE THE CHANCE FOR
SHOWER AND THUNDERSTORM ACTIVITY. HOWEVER...RESIDUAL MOISTURE AND
DAYTIME HEATING WILL BE ENOUGH TO TRIGGER AFTERNOON THUNDERSTORMS
EACH DAY. LESS HUMID WEDNESDAY THROUGH FRIDAY WITH AFTERNOON
TEMPERATURES A FEW DEGREES ABOVE NORMAL.
