THROUGH THE WEEKEND...
SOME WEAK RIDGING IS EXPECTED TO BUILD INTO THE AREA, WHICH SHOULD
CURTAIL OUR ROUNDS OF PRECIPITATION THAT WE'VE BEEN SEEING THE
LAST FEW DAYS. UNFORTUNATELY, OR FORTUNATELY, DEPENDING ON HOW
MUCH FOLKS DESIRE FOR RAIN, WE WILL STILL SEE INTERMITTENT SHOWERS
PARTICULARLY IN OUR EASTERN COUNTIES, DAILY. AN EMBEDDED
THUNDERSTORM OR TWO CAN'T BE RULED OUT, BUT THERE SHOULD BE A NEAR
ZERO CHANCE FOR SEVERE WEATHER ASSOCIATED WITH THESE
THUNDERSTORMS. OVERNIGHT POPS REMAIN BELOW 20% FOR THE WEEKEND.
FOR NEXT WEEK...
DIURNALLY DRIVEN CONVECTION WILL BE THE THEME NEXT WEEK, AS OUR
POPS CLIMB FROM 20-30% EARLY IN THE WEEK, TO MID 50S DURING OUR
DAYTIME HOURS. THIS WILL BE DUE TO OUR OVERALL PATTERN ANCHORING
IN, AND DAYTIME RETURN FLOW CONTINUING TO FEED IN MORE MOISTURE
OVER THE AREA. TEMPERATURES ARE EXPECTED TO CLIMB BACK INTO
SEASONAL NORMS WITH HIGHS SUNDAY/MONDAY IN THE LOW 90S, WHICH
SLOWLY COOL ABOUT A DEGREE OR TWO EVERYDAY TO THE MID 80S NEXT
FRIDAY. HUMIDITY IS EXPECTED TO HOVER FROM 55-65% DURING OUR
DAYTIME HOURS CAUSING OUR HEAT INDEX VALUES TO REACH TRIPLE DIGITS
EARLY NEXT WEEK, ALONG AND SOUTH OF I-20.
ABOUT MID WEAK GUIDANCE DOES PICK UP ON A WEAK FRONT NUDGING ITS
WAY INTO THE AREA, WHICH COULD BRING RELIEF TO THOSE HEAT INDEX
VALUES, AND AT THE MOMENT IT LOOKS AS THOUGH THE GTR AREA HAS THE
HIGHEST CONFIDENCE FOR A SUBTLE DECREASE IN BOTH TEMP AND DEW
POINTS. ALL OTHER AREAS COULD SEE HEAT INDEX VALUES DROP BELOW THE
TRIPLE DIGIT THRESHOLD AS WELL, BRINGING SOME MUCH NEEDED
RELIEF./OAJ/
