DISCUSSION
ISSUED AT 244 PM CDT SUN JUN 28 2026
QUASI-ZONAL FLOW ALOFT HAS MODIFIED WITH RIDGING STRENGTHENING
JUST EAST OF THE MISSISSIPPI RIVER VALLEY. THIS, IN COMBINATION
WITH ONSHORE SURFACE FLOW, WILL ALLOW FOR MAXIMIZED WARM AIR
ADVECTION/MAINTENANCE THROUGH TUESDAY FOR TEMPERATURE MAXIMUMS IN
THE MID-TO-UPPER 90S. THIS RIDGE IS EXPECTED TO SHIFT FURTHER EAST
TO MAXIMIZE IN STRENGTH OVER THE OHIO RIVER VALLEY. OUTLOOKS FROM
THE NATIONAL HURRICANE CENTER HIGHLIGHT A DISTURBANCE SOUTH OF
THE CAROLINA COASTS THAT IS EXPECTED TO EVENTUALLY SLIP WEST ALONG
THE GULF COAST AND AROUND THE SOUTHERN PERIPHERY OF THIS RIDGE BY
THURSDAY. DIURNALLY-DRIVEN CONVECTIVE MODES WILL BECOME MORE
LIKELY AS A RESULT. A PROLONGED IMPORT OF GULF MOISTURE WILL KEEP
IMPACTFUL HEAT IN PLACE BY INDEPENDENCE DAY, WITH A 50 TO 75
PERCENT CHANCE OF TEMPERATURES GREATER THAN 95 DEGREES. LONG-RANGE
GUIDANCE SUGGESTS ANOTHER ROUND OF HOT SUMMER WEATHER WITH MORE
RIDGING BUILDING IN ALOFT BEYOND NEXT WEEKEND.
WITH DEW POINTS EXPECTED TO REMAIN IN THE LOW-TO-MID 70S THROUGH
THIS TIME, HAZARDOUS HEAT WILL BE IMPACTFUL FOR ALL GROUPS OF
PEOPLE AND NOT JUST HEAT-SENSITIVE GROUPS. ADEQUATE PRECAUTIONS
AND AWARENESS ARE ENCOURAGED NOW AGAINST THE ELEVATED POTENTIAL
FOR HEAT ILLNESSES. THIS INCLUDES (AND IS NOT LIMITED TO) ALTERING
OUTDOOR PLANS, TAKING FREQUENT BREAKS IF YOU MUST BE OUTSIDE,
CHECKING THE BACKSEAT OF YOUR VEHICLE, AND KNOWING THE SIGNS AND
SYMPTOMS OF HEAT EXHAUSTION IN ADDITION TO HEAT STROKE. /16/
