DISCUSSION
ISSUED AT 339 AM CDT SUN AUG 9 2026
AN ANOMALOUSLY STRONG RIDGE REMAINS OVER THE FOUR CORNERS
REGION, BUT THE BERMUDA HIGH IS BEGINNING TO RETROGRADE FROM THE
ATLANTIC TO THE GULF COAST. AS IT TREKS WESTWARD THIS WEEK, IT
WILL COME TO BE THE DOMINANT FEATURE IN OUR SYNOPTIC PATTERN AND
BECOME A STRONGER LIMITING FACTOR FOR RAIN CHANCES. HIGH PWAT
VALUES NEAR 2 INCHES WILL PERSIST IN THE REGION THROUGH MIDWEEK,
SO INCREASING HEAT WILL PUSH OUR DAILY HEAT INDEX VALUES MORE
RELIABLY OVER 105 DEGREES ACROSS THE AREA TOMORROW ONWARD. SHOWERS
AND THUNDERSTORMS WILL BRING SPOTTY RELIEF FROM THE HEAT. DRIER
AIR WILL WRAP FROM THE GULF AND SOUTHWESTERN US AS THE RIDGE
BECOMES MORE PREVALENT, AND PWAT VALUES WILL FALL CLOSER TO 1.5
INCHES BY NEXT FRIDAY AND SATURDAY. THE INCREASING TEMPS MAY BE A
LITTLE OFFSET BY THE DECREASING HUMIDITY, BUT SUFFICE IT TO SAY
THAT HEAT STRESS WILL BE A CONCERN AS WE PUSH SOLIDLY INTO MID
AUGUST. /NF/
