DISCUSSION
ISSUED AT 126 AM CDT THU SEP 10 2026
WEDNESDAY TURNED OUT TO BE MORE ACTIVE THAN ANTICIPATED, ESPECIALLY
ACROSS THE RIO GRANDE PLAINS. SIMILAR CONDITIONS ARE IN STORE FOR
TODAY WITH A MID LEVEL TROUGH ACROSS S TX COMBINED WITH DEEP
MOISTURE. SEVERAL MODELS KEEP THE HIGHEST PROBABILITIES ACROSS THE
VICTORIA CROSSROADS WITH VERY LOW CHANCES ACROSS THE RIO GRANDE
PLAINS. THIS IS DUE TO THE MID LEVEL TROUGH SHIFTING SLIGHTLY
NORTHEASTWARD WITH A STRENGTHENING MID/UPPER LEVEL NORTHERLY FLOW
DEVELOPING ACROSS THE WESTERN AREAS AND LEADING TO A MORE SUBSIDENT
ENVIRONMENT. THAT BEING SAID, THE DEEP MOISTURE AND UNSTABLE
ENVIRONMENT MAY BE ENOUGH TO OVERCOME THE SUBSIDENCE.
RAINFALL TOTALS THROUGH FRIDAY ARE EXPECTED TO BE GENERALLY LESS
THAN 0.25 INCH, BUT WITH PWATS CONTINUING TO RANGE FROM 2.0-2.3
INCHES, A FEW STRONGER STORMS MAY PRODUCE 1-2 INCHES. RAIN CHANCES
ARE PROGGED TO DECREASE THROUGH FRIDAY AFTERNOON AND INTO THE
WEEKEND AS MID LEVEL RIDGING BUILDS BACK ACROSS S TX.
AN EXTREME RISK OF HEAT RELATED IMPACTS ARE FORECAST ACROSS MOST OF
S TX BY THE WEEKEND. ALTHOUGH, HEAT INDICES UP TO 113 MAY OCCUR THIS
AFTERNOON , IT IS EXPECTED TO BE ISOLATED WITH A SHORT DURATION,
THUS A HEAT ADVISORY WILL NOT BE ISSUED AT THIS TIME. HOWEVER, BY
FRIDAY AND INTO THE WEEKEND THE DURATION OF HEAT INDICES OF 110+
ACROSS A LARGER AREA MAY WARRANT DAILY HEAT ADVISORIES, POSSIBLY
THROUGH EARLY NEXT WEEK.
