NEAR TERM
(TONIGHT)
ISSUED AT 139 PM CDT SUN AUG 30 2026
AFTERNOON CU SCATTERS THE SKY THIS AFTERNOON, OTHERWISE IT IS
CURRENTLY IN THE UPPER 80S WITH LIGHT SOUTHEASTERLY WINDS. HEAT
INDEX VALUES ARE NOT TOO BAD TODAY, IN THE 90S, BUT THAT WILL NOT
BE THE CASE FOR THIS UPCOMING WEEK. THE CU WILL FADE WITH SUNSET,
AND WITH MOSTLY CLEAR SKIES, WILL NOT RULE OUT SOME PATCHY FOG FOR
THOSE IN SHELTERED LOCATIONS, VALLEYS AND NEAR BODIES OF WATER.
OTHERWISE, LOOK FOR LOWS AROUND 70 DEGREES. NO CHANGES MADE TO
TONIGHT'S FORECAST.
SHORT TERM
(MONDAY THROUGH WEDNESDAY)
ISSUED AT 942 AM CDT SUN AUG 30 2026
THE FORECAST CONCERNS FOR THE SHORT TERM REMAIN THE SAME: HEAT.
THIS HEAT DOME THAT IS DRAPED FROM THE CENTRAL PLAINS OVER TO THE
MID-ATLANTIC, ITS CENTER WILL CONTINUE TO SLIDE EASTWARD THIS
WEEK. THIS WILL INCREASE OUR HEAT RISK BUT THE SUBSIDENCE WILL
KEEP SHOWERS OUT OF THE FORECAST THROUGH MID WEEK. THE NWS
HEATRISK WILL START OFF AT A LEVEL 2 (MODERATE) ON MONDAY BUT AS
THE RIDGE STRENGTHENS ACROSS THE REGION, LEVEL 3 (MAJOR) WILL
START TO APPEAR ACROSS THE FORECAST AREA NEXT WEEK. FOR TEMPS,
THEY WILL BE IN THE LOWER 90S ON MONDAY, BUT IN THE MID TO UPPER
90S TUESDAY AND WEDNESDAY (SLIGHTLY COOLER IN THE HIGHER
ELEVATIONS). HEAT INDEX VALUES WILL CLIMB AS WELL WITH MOST OF US
SEEING VALUES 100-105 BUT A FEW SPOTS SEEING UP TO 107, ESPECIALLY
TUESDAY AND WEDNESDAY. DID SEE THAT THE WBGT VALUES ARE IN THE
80S NEXT WEEK WITH A GOOD CHUNK OF US AROUND 88 DEGREES ON TUE
AND WED. WITH LOWS STICKING IN THE 70S AT NIGHT, THERE WON'T BE
MUCH OF A RELIEF. NO HEAT ADVISORY ISSUED AT THIS TIME, HOWEVER
TEMP, HEAT INDEX AND WBGT VALUES AND THEIR COVERAGE WILL BE
MONITORED FOR THE NEED OF A HEAT PRODUCT AT A LATER TIME.
LONG TERM
(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 821 PM CDT SAT AUG 29 2026
A STOUT UPPER RIDGE AS WELL AS HIGH PRESSURE TO OUR NORTHEAST OVER
THE APPALACHIANS WILL KEEP MOST SHOWER AND STORM ACTIVITY OUT OF THE
FORECAST (ASIDE FROM PERHAPS LOW CHANCES OVER THE TERRAIN) THROUGH
THE NEXT WEEK. THEREFORE, HOT AND HUMID CONDITIONS WILL CONTINUE TO
BE THE THEME NEXT WEEK WITH FORECAST HIGHS IN THE LOWER TO MID 90S,
LOWS IN THE LOWER TO MID 70S, AND DEW POINTS IN THE UPPER 60S TO
LOWER 70S EACH DAY. THIS WILL RESULT IN HEAT INDICES RANGING BETWEEN
100-107 DEGREES EACH DAY, ALONG WITH NWS HEATRISK IN THE MODERATE TO
MAJOR (LEVELS 2 AND 3 OF 4) CATEGORIES EVERY DAY AND WBGTS IN THE MID
TO UPPER 80S EACH AFTERNOON. WE'LL NEED TO KEEP AN EYE TO SEE IF ANY
HEAT PRODUCTS WILL BE NECESSARY; HOWEVER, REGARDLESS, PLEASE
PRACTICE HEAT SAFETY! THIS IS ESPECIALLY IMPORTANT IF YOU WORK
OUTDOORS OR HAVE OUTDOOR ACTIVITIES. MAKE SURE TO DRESS IN LIGHT-
COLORED, LOOSE-FITTING CLOTHING, DRINK PLENTY OF WATER, AND TAKE
FREQUENT BREAKS IN THE SHADE. ALSO, NEVER LEAVE PEOPLE OR PETS IN
VEHICLES!
