DISCUSSION
ISSUED AT 1203 PM CDT MON OCT 26 2026
WARM AND MOSTLY DRY CONDITIONS ARE EXPECTED ACROSS REGION THIS WEEK.
A NEARBY SHORTWAVE AND INCREASED GULF MOISTURE WILL ALLOW FOR
DAILY LOW TO MEDIUM (10-50%) CHANCES OF DIURNALLY DRIVES SHOWERS
AND THUNDERSTORMS THROUGH WEDNESDAY, PRIMARILY ALONG AND EAST OF
I-69C. THURSDAY, RAIN CHANCES REMAIN IN THE FORECAST, BUT BEST
CHANCES WILL BE ALONG AND WEST OF I-69E DUE TO EXCESS MOISTURE
MOVING INTO NORTHEASTERN MEXICO AND TEXAS FROM THE REMNANTS OF
TROPICAL STORM VANCE, CURRENTLY LOCATED OFF THE MEXICAN PACIFIC
COAST. RAIN CHANCES TAPER OFF LATE WEEK.
TEMPERATURES WILL REMAIN SLIGHTLY ABOVE NORMAL AND SLOWLY CLIMB INTO
THE LOW TO MID 90S BY THIS WEEKEND. OVERNIGHT LOWS WILL BE IN THE
MID 60S TO LOW 70S FOR MUCH OF THE WEEK, WITH LOWS IN THE 70S BY
LATE WEEK INTO THE WEEKEND.
EASTERLY FLOW ACROSS THE GULF INCREASES THE THREAT OF RIP CURRENTS
THIS WEEK. ADDITIONALLY, ASTRONOMICAL TIDES WILL NARROW BEACHES
DURING HIGH TIDE CYCLES EACH AFTERNOON AND EVENING. A COASTAL FLOOD
STATEMENT IS IN EFFECT TODAY FROM 3 PM UNTIL MIDNIGHT AND
ADDITIONAL COASTAL FLOOD STATEMENTS MAY BE NEEDED OVER THE NEXT
DAY OR TWO.
