DISCUSSION
ISSUED AT 136 PM CDT FRI JUL 31 2026
SATURDAY THROUGH MONDAY...A SOMEWHAT OPENING UPPER LOW MOVES FROM
OVER THE CENTRAL PLAINS TO THE MID WEST, TAKING AN ASSOCIATED
SURFACE LOW WITH. I SAY SOMEWHAT OPENING, BECOME SOME GUIDANCE IS
MAINTAINING AN UPPER LOW OVER THE MIDWEST. AS THIS SYSTEM MOVES
EAST, THE BASE DIGS SOUTH OVER THE SOUTHEAST, SHIFTING AN UPPER
RIDGE THAT IS PUSHING EAST OVER THE NORTHERN GULF COAST BACK WEST. A
TRAILING WEAK COLD FRONT MOVES SOUTH OVER THE LOWER MISSISSIPPI
RIVER VALLEY, THEN THE WESTERN HALF OF THE SOUTHEAST OVER THE
WEEKEND INTO THE COMING WEEK. GUIDANCE IS ADVERTISING THIS FRONT
MOVING SOUTHEAST ACROSS THE FORECAST AREA LATE SATURDAY INTO SUNDAY
BEFORE STALLING SOUTHEAST OF THE FORECAST AREA BY MONDAY. THIS FRONT
IS EXPECTED TO USHER IN MAINLY A DRIER AIRMASS OVER THE FORECAST
AREA, AS APPOSED TO COOLER TEMPERATURES. PRECIPITABLE H20 VALUES
DROP FROM THE 2.1"-2.3" RANGE TODAY INTO SATURDAY DROP INTO THE 1.3"-
1.5" RANGE BY MONDAY MORNING. SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS EXPECTED TODAY WILL DECREASE AND SHIFT EAST SATURDAY,
THEN SOUTHEAST SATURDAY NIGHT ON WITH THE DROP IN DEEP LAYER
MOISTURE. THE EASTWARD SHIFT IS DUE TO AN UPPER LEVEL SHORTWAVE
MOVING SOUTHEAST ACROSS THE FORECAST AREA LATER TODAY THROUGH
TONIGHT. PULSE TYPE SEVERE STORMS REMAIN A POSSIBILITY THIS
AFTERNOON, SHIFTING SOUTH TO THE COAST BY SUNDAY.
EVEN WITH THE UPPER RIDGE MOVING OFF, THE DRIER AIRMASS WILL ALLOW
FOR BETTER DAYTIME HEATING, KEEPING HIGH TEMPERATURES AROUND
SEASONAL NORMS OVER THE WESTERN HALF OF THE FORECAST AREA (AROUND 90
TO LOW 90S). THE EASTERN HALF OF THE FORECAST AREA SEES A DROP IN
HIGH TEMPERATURES OVER THE WEEKEND, TO THE UPPER 80S TO NEAR 90, AS
THE BETTER CHANCE OF RAIN SHIFTS EAST. THE DROP IN MOISTURE LEVELS
WILL ALLOW FOR BETTER OVERNIGHT COOLING, MAINLY SUNDAY ON, WITH LOW
TEMPERATURES IN THE MID TO UPPER 70S TONIGHT DROPPING INTO THE LOW
70S INLAND FROM THE COAST SUNDAY AND MONDAY, THOUGH NEAR COASTAL AND
COASTAL LOW TEMPERATURES REMAIN IN THE UPPER 70S. HEAT INDICES DROP
WITH THE DECREASE IN MOISTURE LEVELS, DROPPING TO BELOW 100 BY
MONDAY.
MONDAY NIGHT ON...THE UPPER LOW OVER THE MIDWEST MEANDERS EAST INTO
MID WEEK BEFORE GETTING DEFLECTED NORTHEAST BY AN UPPER RIDGE OFF
THE EAST COAST THE END OF THE WEEK. THIS LOW'S ASSOCIATED SURFACE
LOW WILL HELP TO MAINTAIN DRY NORTHWESTERLY FLOW OVER THE FORECAST
AREA INTO WEDNESDAY, KEEPING A DRY FORECAST. THE END OF THE WEEK, AS
THE UPPER LOW MOVES OFF, THE UPPER HIGH OVER THE PLAINS BUILDS EAST
OVER THE SOUTHEAST, A SURFACE RIDGE BUILDS OVER THE SOUTHEAST,
RESTORING ONSHORE FLOW TO THE SOUTHEAST AND INCREASING MOISTURE
LEVELS. RAIN CHANCES SEE A BIT OF AN INCREASE THE END OF THE WEEK,
THOUGH WITH THE UPPER RIDGE BUILDING EAST OVER THE SOUTHEAST, THIS
INCREASE IS SMALL. TEMPERATURES SEE A RISE WITH THE INCREASE IN
INFLUENCE FROM THE UPPER RIDGE, BACK TO ABOVE SEASONAL NORMS. WITH
MOISTURE LEVELS SLOW TO INCREASE, THE RISE IN HEAT INDICES IS ALSO
SLOW, RISING TO THE 100-107 RANGE BY FRIDAY.
TAKING A LOOK AT THE RIP CURRENT RISK ON AREA BEACHES, THE
APPROACHING SURFACE BOUNDARY WILL INTERACT WITH A SURFACE RIDGE
OVER THE GULF, CREATING A TIGHTER PRESSURE GRADIENT ALONG THE COAST
AND MODERATE WEST TO SOUTHWEST WINDS. THIS WILL INCREASE THE RIP
RISK TO HIGH BY LATE SATURDAY, WITH THE FLORIDA COAST SEEING THE
UPTICK FIRST. WINDS BEGIN TO EASE MONDAY, WITH A MODERATE RIP RISK
MONDAY DROPPING TO LOW BY TUESDAY.
