ONE LAST DRY WEATHER DAY TODAY WITH SHORTWAVE RIDGING IN PLACE,
STILL REMAINING COOLER THAN NORMAL VALUES WITH HIGHS ONLY IN
THE 60S. BREEZY TO GUSTY EASTERLY WINDS TODAY WITH GUSTS AROUND
25 MPH. ON FRIDAY, A TROUGH MOVING IN FROM THE SOUTHWEST WILL
BRING CHANCES OF RAIN SHOWERS INTO THE AREA FROM THE SOUTH AND
WILL PUSH NORTHWARD THROUGH THE DAY WITH MOISTURE ADVECTING
NORTHWARD. SURFACE DEW POINTS WILL GO FROM THE 40S TODAY AND
WILL QUICKLY MOISTEN UP ON FRIDAY AND INCREASE INTO THE 50S AND
60S BY FRIDAY EVENING. FURTHER INCREASES WILL MAKE FOR HUMID
CONDITIONS ON SATURDAY WITH VALUES INTO THE UPPER 60S TO LOW
70S. SATURDAY WILL ALSO BE BREEZY TO GUSTY WITH SLIGHTLY HIGHER
GUSTS FROM THE SOUTHEAST THAN TODAY WITH GUSTS UP TO AROUND 30
MPH. WPC HAS OUR AREA IN A MARGINAL RISK OF EXCEEDING FLASH
FLOOD GUIDANCE LATE FRIDAY INTO SATURDAY. TOTAL RAINFALL
ACCUMULATIONS WILL RUN ABOUT 0.50" TO 0.75" FOR AREAS NORTHWEST
OF ABOUT I-69 CORRIDOR AND RANGE ABOUT 0.75" TO 1.00" SOUTHEAST
OF THE CORRIDOR. SO A GOOD HEARTY RAINFALL IS EXPECTED WITH THE
VERY MOIST INFLUX INTO THE DISTURBANCE.
THIS RAINFALL AND DISTURBANCE WILL ALSO BE ACCOMPANIED BY
WARMING TEMPERATURES FOR FRIDAY INTO THE WEEKEND. HIGHS INTO THE
MID 60S TO LOW 70S ON FRIDAY AND THEN 70S ON SATURDAY AND
WARMER YET WITH HIGHS IN THE UPPER 70S TO LOW 80S ON SUNDAY INTO
THE MEMORIAL DAY HOLIDAY. PERIODS OF RAIN SHOWERS AND EMBEDDED
THUNDERSTORMS EXPECTED THROUGH THE WEEKEND AND INTO THE MIDDLE
OF NEXT WEEK. BEST CHANCES FOR THUNDERSTORMS TO MIX IN WILL BE
THE AFTERNOON HOURS EACH DAY. SEVERE THUNDERSTORMS ARE NOT
EXPECTED THROUGH THIS FORECAST PERIOD. THE HOLIDAY WEEKEND STILL
DOES NOT LOOK LIKE A COMPLETE WASHOUT WITH BREAKS IN THE
SHOWERS. HOWEVER, FAIRLY DIFFICULT TO PINPOINT WHERE AND WHEN
THE CONVECTIVE SHOWERS WILL EXACTLY DEVELOP.
