DISCUSSION...
REGIONAL MOSAIC RADAR EARLY THIS MORNING SHOWS A LARGE AREA OF
MOSTLY LIGHT SHWRS EXTENDING FROM W CENTRAL TX INTO CENTRAL OK AND
NERN AR...APPARENTLY ASSOCIATED WITH A WEAK DISTURBANCE MOVING
ACROSS THESE AREAS. THE RIDGE REMAINS CENTERED TO OUR SE OVER THE
LA/MS GULF COAST. THE EURO SEEMS TO BE ONE OF THE ONLY MODELS THAT
IS INITIALIZING WELL WITH REGARD TO THE ONGOING SHWRS. AS THIS
DISTURBANCE TRANSLATES EWD TODAY...IT IS SOMEWHAT UNCLEAR AS TO
WHETHER THESE SHWRS WILL AFFECT PARTS OF OUR REGION
TODAY...ESPECIALLY GIVEN THE PRESENCE/INFLUENCE OF THE UPPER
RIDGE. THE EURO DOES PLACE SOME QPF ACROSS OUR NERN AREAS...SO
HAVE GONE AHEAD WITH SOME 20 POPS. ADDITIONALLY...THE TROPICAL
WAVE IN THE CENTRAL GULF OF MEXICO WILL INTERACT WITH A STALLED
BOUNDARY/THE SEA BREEZE TO PRODUCE CONVECTION MAINLY DURING PEAK
HEATING...AND SOME OF THIS COULD WORK ITS WAY INTO OUR EXTREME SRN
AREAS.

CHANCES FOR SCT CONVECTION WILL CONTINUE THROUGH THURSDAY...AS
THE UPPER TROF CURRENTLY OVER THE NRN HIGH PLAINS DIGS SEWD AND
INTERACTS WITH THE REMNANT BOUNDARY THAT MOVED THROUGH OUR REGION
A FEW DAYS AGO. TEMP GUIDANCE HAS WARMED UP OVER THE LAST COUPLE
OF RUNS...WHICH CAN BE EXPLAINED BY THE FACT THAT THE SCT NATURE
OF ANY CONVECTION/CLOUD COVER WILL ALLOW FOR A GOOD BIT OF DAYTIME
HEATING.

THE UPPER RIDGE WILL QUICKLY MOVE OVHD AND TO THE E DURING
FRIDAY...AS A MORE POTENT UPPER TROF MOVES INTO THE WRN U.S.
REMNANTS OF HURRICANE ODILE ARE FCST TO BE SWEPT UP INTO THIS
PROGRESSIVE TROF AS IT MOVES ACROSS THE CENTRAL PLAINS SATURDAY.
MODELS IN SURPRISINGLY GOOD AGREEMENT THAT THIS TROF WILL EQUAL
SOME RAINFALL FOR AT LEAST PARTS OF OUR REGION DURING NEXT
WEEKEND...WITH THE POTENTIAL TO PUSH US CLOSER TO COOLER FALL
TEMPERATURES. /12/
