..NEW AVIATION
KEY MESSAGES
- WIDESPREAD SHOWER AND THUNDERSTORM CHANCES RETURN THIS WEEKEND.
- MONITORING THE POTENTIAL FOR INCREASING HEAT DANGER NEXT WEEK.
DISCUSSION
ISSUED AT 330 AM CDT FRI JUN 5 2026
TODAY THROUGH NEXT THURSDAY...THE MAIN FOCUS DURING THE FORECAST
PERIOD WILL BE FROM THIS WEEKEND INTO THE MIDDLE OF NEXT WEEK.
AFTER A COUPLE OF PLEASANT AND QUIET DAYS ACROSS THE FORECAST
AREA, RAIN CHANCES WILL RETURN TO THE FORECAST OVER THE UPCOMING
WEEKEND AS A SLUG OF MOISTURE LIFTS NORTH OUT OF THE GULF AND INTO
THE LOWER MISSISSIPPI RIVER VALLEY, WHILE WEAK DISTURBANCES MOVE
THROUGH THE REGION. THIS WILL RESULT IN A GOOD COVERAGE OF SHOWERS
AND STORMS DEVELOPING ACROSS THE FORECAST AREA BOTH SATURDAY AND
SUNDAY. WHILE CURRENTLY NOT FORECAST, WITH PRECIPITABLE H2O VALUES
OVER THE WEEKEND ADVERTISED IN THE 2-2.5 INCH RANGE, RAINFALL
COULD BE PRETTY EFFICIENT AND HEAVY AT TIMES. AS A RESULT, SOME
CONCERN FOR FLOODING MAY ARISE AS WE MOVE INTO THE WEEKEND. THIS
WILL OF COURSE CONTINUE TO BE MONITORED IN LATER FORECASTS.
AS ELUDED TO ABOVE, VERY HUMID CONDITIONS WILL ALSO RETURN TO THE
FORECAST AREA THIS WEEKEND, AND LINGER INTO NEXT WEEK. THIS DEEPLY
MOIST AIRMASS ACROSS THE REGION NEXT MONDAY THROUGH WEDNESDAY WILL
KEEP SOME CHANCE FOR ISOLATED TO SCATTERED AFTERNOON CONVECTION IN
THE FORECAST. IT'LL ALSO BE DURING THIS TIMEFRAME WHERE THE CONCERN
FOR HEAT STRESS WILL BE ON THE RISE WITH THE SUBTROPICAL RIDGE
STRENGTHENING. AS WE SAW RECENTLY, ABOVE NORMAL RAINFALL IN RECENT
WEEKS WILL SUPPORT HIGHER BOUNDARY LAYER HUMIDITY AND HEAT STRESS.
AGAIN, THIS WILL CONTINUE TO BE MONITORED IN LATER FORECASTS.
