DISCUSSION
THE SHORT-TERM PATTERN REMAINS UNCHANGED WITH SOUTHERN WINDS
BRINGING HIGH RH VALUES AND WARM TEMPERATURES TO OUR REGION.
RAIN CHANCES WILL RETURN LATE TUESDAY AS A FRONT MOVES ACROSS THE
REGION. RAIN TOTALS LOOK TO REMAIN LOW, BELOW 0.25 INCHES, WITH
SOME THUNDERSTORMS POSSIBLE.
BEHIND THE FRONT, A SMALL SHOT OF DRY AIR WILL CAUSE MINIMUM RH
VALUES TO DROP INTO THE 30 TO 50% RANGE ON WEDNESDAY. MIN RH
VALUES THEN SLOWLY CREEP BACK UP THROUGH THE END OF THE WEEK,
RETURNING TO THE LOW 50S TO LOW 60S BY SATURDAY.
