.DISCUSSION...
YET ANOTHER HOT DAY ACROSS THE REGION WITH MANY LOCATIONS ALREADY
INTO THE TRIPLE DIGITS. CONVECTION VERY SLIM TO SAY THE LEAST THIS
AFTERNOON. 12Z SOUNDING AT SHV SHOWED LOWER PRECIPITABLE WATER
COMPARED TO 24 HRS AGO AND THIS IS EVIDENT ON WATERVAPOR IMAGERY
WITH DRIER AIR MAKING A PUSH SOUTHWARD INTO THE REGION. MCS
CONTINUES TO MOVE RAPIDLY EASTWARD TO OUR NORTH WITH A TRAILING
OUTFLOW BOUNDARY WHICH EXTENDS FROM NEAR LIT...TO DEQ TO NEAR PRX.
WITH THE BEST CU FIELD ACROSS THIS REGION...WILL RESERVE MY
HIGHEST POPS TONIGHT ALONG AND NORTH OF THE I-30 CORRIDOR...ONLY
GOING ISOLATED ELSEWHERE.

OTHER THAN AN OCCASIONAL WOBBLE...OUR UPPER RIDGE SHOULD REMAIN
LOCKED ACROSS THE FOUR STATE REGION UNTIL AT LEAST THURSDAY. WILL
THEREFORE KEEP CURRENT HEAT ADVISORY GOING THROUGH THURSDAY AND
REEVALUATE EXTENDING FOR FRIDAY FOR LATER SHIFTS. BY FRIDAY...
NAM IS A LITTLE MORE ADVANTAGEOUS IN RETROGRADING THE RIDGE
WESTWARD INTO WEST TEXAS THAN THE OTHER SHORT TERM MODELS. IF THIS
WERE THE CASE...WE COULD SEE A SLIGHT MODERATING TREND IN THESE
OPPRESSIVE TEMPERATURES NOT TO MENTION BE IN A MORE FAVORABLE
REGION (RELATIVE TO THE RIDGE) FOR SCATTERED THUNDERSTORMS. WILL
NOT BITE ON THIS JUST YET...INSTEAD GOING WITH THE MORE STUBBORN
GFS WHICH LOCKS THE RIDGE IN LONGER AND KEEPS TEMPERATURES HOT.
MODELS HAVE BEEN QUICK TO INDICATE A COOL DOWN AND HAVE YET TO
SEE IT...THUS MY HESITANCY TO BITE ON A COOLER SCENARIO JUST YET.

EXPOSURE TO THESE CONDITIONS.   FRIENDS...RELATIVES...OR NEIGHBORS
SHOULD ESPECIALLY CHECK ON PEOPLE THEY THINK MIGHT BE AT RISK.

IN ADDITION TO THE HOT TEMPERATURES...ISOLATED THUNDERSTORMS ARE
POSSIBLE ACROSS THE REGION THIS AFTERNOON AND EVENING. ANY ISOLATED
STRONG THUNDERSTORMS WILL HAVE THE CAPABILITY TO PRODUCE STRONG AND
DAMAGING WIND GUSTS ALONG WITH FREQUENT CLOUD TO GROUND LIGHTNING.

EXTREMELY HOT TEMPERATURES AT OR ABOVE 100 DEGREES WILL CONTINUE
DURING THE AFTERNOON...UNTIL AT LEAST THURSDAY. THUS...THE HEAT
