DISCUSSION
(THIS AFTERNOON THROUGH NEXT SUNDAY)
ISSUED AT 1200 PM CDT MON AUG 11 2025
ANOTHER TYPICAL SUMMERTIME DAY IS ON DISPLAY THIS MONDAY WITH
CURRENT TEMPERATURES IN THE UPPER 80S TO LOWER 90S WITH A VERY THIN
STRATUS DECK MOVING OVER THE MID-SOUTH. AN UPPER-LEVEL RIDGE,
CURRENTLY CENTERED OVER THE EAST COAST, WILL CONTINUE TO BREAK DOWN
AS WE MOVE THROUGH MONDAY. BY TUESDAY MORNING, A WEAK UPPER-LEVEL
TROUGH WILL BEGIN PUSHING INTO THE MIDDLE MISSISSIPPI VALLEY, AND
WINDS TURN MORE SOUTHERLY, USHERING IN INCREASED MOISTURE. AS SUCH,
MORE MENTIONABLE SHOWER AND THUNDERSTORM CHANCES WILL MOVE BACK INTO
THE FORECAST TUESDAY AND INTO WEDNESDAY. THURSDAY WILL BE MUCH THE
SAME AS WEAK NORTHWEST FLOW MO WITH INCREASED
DEWPOINTS BROUGHT IN BY TUESDAY INTO THURSDAY'SVES OVER THE REGION AND SEVERAL
EMBEDDED SHORTWAVES GIVE LIFT TO SHOWERS AND THUNDERSTORMS.
COME FRIDAY, AN UPPER-LEVEL RIDGE WILL BROADEN OVER THE GULF COAST
STATES, DECREASING OUR RAIN CHANCES AND INCREASING TEMPERATURES INTO
THE MID TO UPPER 90S. SOMETHING TO NOTE, THERE IS A DECENT AMOUNT OF
MODEL SPREAD FOR FRIDAY AND INTO THE WEEKEND. AS SUCH, THE STRENGTH
OF THE RIDGE OVER THAT BROADENS OVER THE GULF STATES WILL REALLY
DRIVE OUR WEATHER PATTERN. ENSEMBLE GUIDANCE AND NBM ARE IN A
MORE AGREEMENT WITH THE DRIER SOLUTION INTO THE WEEKEND.
NONETHELESS, THIS WEEKEND WILL BE HOT AND HUMID DUE TO THE
INCREASED MOISTURE PROFILE. AS A RESULT, HEAT INDICES MAY WARRANT
HEAT HEADLINES IN THE LATTER PART OF THE WEEK. BOTTOM LINE, WE'RE
STUCK IN THIS SUMMERTIME PATTERN WITH SLIGHTLY ABOVE NORMAL
TEMPERATURES.
