DISCUSSION
ISSUED AT 1234 AM CDT SUN AUG 30 2026
FAIR SKIES TONIGHT WITH LOW TO MID 70S ALREADY IN SOUTHERN
ARKANSAS, MOST LOCALES ARE WARMER IN THE UPPER 70S AND LOWER 80S
AT MIDNIGHT. LIGHT SE WINDS AROUND 5 MPH ARE BLOWING AND WILL BE
PREVAILING FOR MUCH OF THE WEEK AHEAD. WE HAD SOME NICE NE WIND
SATURDAY AS THE SURFACE HIGH OVER THE APPALACHIANS WAS STILL
HELPING TO MIX OUT THE DEW POINTS. WE HAD SEVERAL SITES IN THE 30%
RANGE FOR RH IN THE MID AFTERNOON. HOWEVER, THE SE WINDS WILL
SLOWLY ELEVATE THE DEW POINTS IN THE COMING DAYS WITH LOWS WARMING
A BIT EACH DAY. THIS WILL ALSO BRING BACK THE HEAT CONCERNS WITH
HEAT INDICES REACHING CRITERIA OF 106 OR MORE IN THE DAYS AHEAD.
HIGH TEMPERATURES WILL LIKELY PEAK TODAY WITH MORE NEAR RECORD
READINGS THIS AFTERNOON IN A FEW SPOTS, WHILE OTHERS WILL REMAIN
OUT OF REACH. THE DAYS AHEAD WILL SEE HIGHS FALL OFF SLIGHTLY,
BUT THE ADDED HUMIDITY WILL BE OUR PROBLEM ONCE AGAIN WITH THE
HEAT INDEX CREEPING UPWARDS EACH DAY. HEADLINES FOR SUCH WILL
START TO FILTER BACK INTO THE REGION DURING THE WORKWEEK. THE
UPPER HIGH HAS LEFT THE INTERMOUNTAIN WEST AND DESERT SOUTHWEST,
EXPANDING BACK OVER THE PLAINS AND MIDDLE MS RIVER VALLEY TODAY.
THIS WILL BUMP THE SUBSIDENCE FOR US, BOOSTING TEMPS IN SOME CASES
AND REALLY LIMITING CONVECTION. ALTHOUGH WE WILL HAVE TO ENDURE
MORE MUGGY HEAT, THE CHANCE FOR RAINFALL WILL SLOWLY SEE AN
UPTICK IN COVERAGE AS THE UPPER HIGH DRIFTS FARTHER EASTWARD AND
WEAKENS. IN ADDITION, THE SE WINDS PREVAILING WILL HELP TO USHER
THE SEA BREEZE NORTHWARD. ONE MODELED WEAKNESS WILL KEEP OFFSHORE
OF NEW ORLEANS TODAY, BUT MOVING TOWARD HOUSTON FOR MONDAY. ON THE
BACK SIDE OF THE WEAKNESS A LITTLE BETTER PUSH WILL LIFT ACTIVITY
INTO OUR SOUTHERN TIER. BY MIDWEEK, A SECONDARY WAVE AND WEAK
UPPER LOW ALOFT WILL RIDE UP INTO THE LOWER MS RIVER VALLEY WITH
EVEN SOME QPF SIGNAL INTO SOUTH ARKANSAS AND EAST TEXAS BY
THURSDAY. THE REMNANTS OF DOLLY FOLLOW SUITE MOVING WESTWARD
ALONG THE GULF COAST BY THIS TIME NEXT WEEK AND COULD FURTHER
INCREASE CONVECTION IN OUR AREA FOR THE LABOR DAY LONG WEEKEND.
