DISCUSSION
ISSUED AT 106 PM CDT TUE JUL 7 2026
AN UPPER LEVEL TROUGH OF LOW PRESSURE EXTENDING FROM NEW ENGLAND
SOUTHWESTWARD AND SFC HIGH PRESSURE OVER THE SE U.S. HAS LED TO A BIT
MORE UNSETTLED WEATHER THAN PREVIOUSLY ANTICIPATED. WHILE RAIN
CHANCES OVERALL WILL REMAIN LOW (20% OR LESS) OVER THE NEXT FEW
DAYS, HIGH MOISTURE CONTENT WILL ALLOW ANY THUNDERSTORM OR SHOWER
ACTIVITY TO PRODUCE HEAVY RAINFALL. THIS COULD LEAD TO LOCALIZED
AREAS OF PONDING OF WATER OF ROADWAYS AND LOW LYING/POOR DRAINAGE
AREAS.
LATE WEEK, MOISTURE WILL DEEPEN ALLOWING FOR SLIGHTLY HIGHER
CHANCES OF PRECIPITATION, ESPECIALLY FRIDAY AFTERNOON (20-30%).
THE HIGH PWATS WILL LEAD TO AREAS OF HEAVY RAIN WITH LOCALIZED
AREAS OF PONDING OF WATER. RAIN CHANCES WILL TAPER OFF THROUGH
SATURDAY.
TEMPERATURE WISE, NOT EXPECTING MUCH CHANGE IN WHAT WE HAVE SEEN.
ANY CLOUD COVER AND PRECIPITATION CHANCES WILL HELP COOL THINGS
OFF AND LOWER THE HEAT RISK AT TIMES THROUGH THE WEEK. EXPECTING
GENERALLY MODERATE HEAT RISK ACROSS THE REGION, ESPECIALLY HEADED
INTO THE WEEKEND AND NEXT WEEK. HEAT INDICES ARE EXPECTED TO BE
BETWEEN 100 AND 110 DEGREES EACH DAY.
THERE IS A LOW RISK OF RIP CURRENTS AT AREA BEACHES THROUGH COULD
INCREASE TO MODERATE BY THINS WEEKEND.
