.DISCUSSION...
CURRENT TEMPS ACROSS THE REGION ALREADY THREATENING RECORDS
WITH 2-3 HRS OF HEATING STILL TO GO. UNFORTUNATELY...CANNOT FIND
ANYTHING EVIDENCE TO SUPPORT LOWER TEMPS FOR WED AND THU. 700
MB RIDGE CURRENTLY CENTERED OVER CENTRAL OK IS FCST TO MAINTAIN
INTENSITY...AND DRIFT SLIGHTLY EWD OVER THE NEXT COUPLE OF DAYS.
EXCESSIVE HEAT WARNING WILL LIKELY NEED TO BE EXTENDED.
FRI AND INTO THE WEEKEND...IT APPEARS THAT MOISTURE ACCOMPANYING
A WEAK FRONTAL BOUNDARY MAY KEEP TEMPS AT BAY JUST A BIT. THIS
FCST...COMBINED WITH A BIT OF CONSERVATISM...LED TO TRENDING TEMPS
SLIGHTLY COOLER THAN STATUS QUO FOR THE MID TERM. WEATHER PATTERNS
LIKE THE PRESENT ARE TOUGH TO BREAK...SO THERE IS DEFINITELY SOME
UNCERTAINTY HERE.
MODELS STILL DEVELOPING A TROF OVER THE EXTREME ERN U.S. DURING
THE MON/TUE TIMEFRAME...WHICH WOULD SQUEEZE THE UPPER RIDGE WWD
OVER W TX. THIS WOULD ALLOW FOR BETTER CHANCES AT AFTN/EVE
CONVECTION...AND LIKELY SOME RELATIVELY COOLER TEMPS. DESPITE SOME
SKEPTICISM...HAVE CONTINUED THE DOWNWARD TEMP TREND...AND ADDED
SOME SLGT CHANCE POPS LATE IN THE PD. HERE/S TO HOPING. /12/
