DISCUSSION
(THIS EVENING THROUGH NEXT SATURDAY)
ISSUED AT 1217 PM CDT SUN JUL 26 2026
HOT WEATHER WILL CONTINUE TO BE THE MAIN CONCERN ACROSS THE
REGION. ALOFT, RIDGING IS CENTERED OVER THE FOUR CORNERS REGION
AND EXTENDS TO THE GULF COAST. THIS IS A FAIRLY STRONG RIDGE FOR
THIS JULY, WITH 500 MB HEIGHTS OVER THE CWA ABOVE THE
CLIMATOLOGICAL 90TH PERCENTILE. PERSISTENT SINKING AIR ASSOCIATED
WITH THIS RIDGE WILL KEEP OUR SKIES CLEAR AND RAIN CHANCES BELOW
10%. AT THE SURFACE, HIGH PRESSURE IS LOCATED IN THE EASTERN GULF,
CREATING CONTINUOUS BUT WEAK ONSHORE FLOW. DEW POINTS WILL SLOWLY
INCREASE, THEN PLATEAU INTO THE MID-70S INLAND AND THE UPPER 70S
ALONG THE COAST. WITH THE CLEAR SKIES DAYTIME HEATING WILL HELP
MIX DOWN SOME OF THE DRY AIR LIMITING DEW POINTS. TEMPERATURES
WILL ALSO STEADILY INCREASE, WITH HIGHS IN THE UPPER 90S AND CLOSE
TO TRIPLE DIGITS FOR NORTHERN PARTS OF THE CWA. HEAT INDEX VALUES
WILL APPROACH THE +108 CRITERIA FOR A HEAT ADVISORY EACH DAY
DURING THE WORK WEEK, WITH THE HOTTEST DAYS OF THE WEEK LOOKING
LIKE TUESDAY AND WEDNESDAY. EVEN WITHOUT HEAT ADVISORIES, MAKE
SURE TO STAY HYDRATED AND TAKE PLENTY OF BREAKS FROM THE HEAT.
THIS PATTERN WILL REMAIN STAGNANT FOR THE NEXT SEVERAL DAYS WITH
LITTLE CHANGE TO OUR SYNOPTIC SETUP. WE WILL START TO SEE THE
RIDGE BEGIN TO WEAKEN AND REBUILD IN THE DESERT SOUTHWEST. THIS
WILL ALLOW FOR TROUGHS TO ROTATE AROUND THE RIDGE INCREASING OUR
RAIN CHANCES FOR THE END OF THE WEEK. WITH THE INCREASE IN RAINS
TEMPERATURES WILL DECREASE SLIGHTLY BACK DOWN INTO THE MID 90S.
