AN UPPER LOW IS CENTERED OVER THE SOUTHERN PLAINS EARLY THIS
AFTERNOON. A SPOKE OF UPPER LEVEL ENERGY WILL MOVE THROUGH LATE
THIS AFTERNOON INTO THIS EVENING WHICH WILL SHOULD KICK OFF
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS AS THE AIRMASS
GRADUALLY DESTABILIZES. COVERAGE WILL DIMINISH WITH LOSS OF
HEATING. LIGHT WINDS AND PLENTY OF LOW LEVEL MOISTURE AROUND
COULD LEAD TO DENSE FOG ESPECIALLY IF WE CAN GET SOME BREAKS IN
THE CLOUDS.
THE UPPER LOW WILL MOVE EAST ACROSS THE MID-SOUTH ON THURSDAY
WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPING

ALONG THE NORTHERN TIER OF COUNTIES. MLCAPE VALUE AROUND 1500
J/KG AND 0-6KM BULK SHEAR VALUES OF ABOUT 30 KTS WILL SUPPORT A
MARGINAL WIND/HAIL RISK THURSDAY AFTERNOON AND EVENING.
THE UPPER LOW WILL DROP SOUTH TO THE GULF COAST FRIDAY INTO
SATURDAY BRINGING DRIER AIR WITH LOWER RAIN CHANCES TO AREAS
NORTH OF I-40. RAIN CHANCES WILL CONTINUE SOUTH OF I-40. TEMPS
WILL REMAIN QUITE COOL WITH HIGHS IN THE 70S FRIDAY AND SATURDAY.
THE UPPER LOW WILL LIFT BACK NORTH AND SLOWLY MOVE ACROSS THE
AREA SUNDAY AND MONDAY WHICH WILL RESULT IN AN INCREASE IN SHOWER
AND THUNDERSTORM COVERAGE AND CONTINUED RELATIVELY COOL TEMPS WITH
HIGHS IN THE 70S.
