DISCUSSION
A SURGE OF TROPICAL MOISTURE IS SPREADING WESTWARD ACROSS THE
FOUR-STATE AREA TODAY AND WE'LL SEE AN UP TICK IN THE COVERAGE OF
SHOWERS AND THUNDERSTORMS THIS AFTERNOON. MIN RH IS VARIED WITH
STILL MID 30% RANGES ACROSS OUR FAR NORTH IN SE OK AND SW AR, BUT
MUCH HIGHER MINS NEAR 50% ALONG I-20 AND NEAR 60% IN OUR SOUTHERN
MOST ZONES AND DISTRICTS. THE WINDS WILL VARY AROUND DOWNPOURS,
BUT PREVAIL E/SE FOR MUCH OF THE DAY. ALOFT, WE ARE ALL EASTERLY
WIND FLOW. AFTER TODAY, THE COVERAGE OF CONVECTION WILL BECOME
SPARSE AGAIN FOR LABOR DAY AND MUCH OF NEXT WEEK. MIN RH WILL FALL
OFF AGAIN TO 30% NORTH TO 50% MINS BY MONDAY AND TUESDAY, SLOWLY
RISING AGAIN MID TO LATE WEEK.
