ISSUED AT 341 AM CDT SAT AUG 8 2026
PATCHY FOG MAY BE POSSIBLE IN THE PRE-DAWN HOURS WILL GRADUALLY MAKE
WAY TO ANOTHER DAY OF HOT CONDITIONS ACROSS THE AREA. HIGH PRESSURE
IN THE FOUR CORNERS AND BERMUDA HIGH OFF THE ATLANTIC COAST WILL
KEEP OUR AREA UNDER A TROUGH PATTERN OVER THE WEEKEND. DIURNAL
CONVECTION WILL BE POSSIBLE INTO THE EARLY EVENING HOURS. A FEW
STORMS MAY BE STRONG TO SEVERE; HOWEVER, WIDESPREAD SEVERE WEATHER
IS NOT EXPECTED. ALTHOUGH CONVECTION WILL BE POSSIBLE, DANGEROUS
HEAT WILL CONTINUE TO BE A CONCERN THROUGH THE WEEKEND. HEAT INDEX
VALUES WILL REMAIN BELOW ADVISORY CRITERIA AND WILL CONTINUE TO
ADVERTISE THE CURRENT "LIMITED" HEAT HWO GRAPHIC.
MONDAY THROUGH FRIDAY:
THE BERMUDA HIGH IS EXPECTED TO AMPLIFY, EXPANDING THE RIDGE INTO
THE SOUTHEAST REGION OVER THE WEEK, INCREASING HUMIDITY AND HEAT
INDEX VALUES. HIGHS RANGING FROM THE MID TO UPPER 90S ALONG WITH
INCREASING HUMIDITY WILL CAUSE CONCERN FOR HEAT STRESS. HEAT
PRODUCTS MAY BE NEEDED MID-WEEK BUT WILL BE EVALUATED AS DAYS
PROGRESS. /SW/
