DISCUSSION
ISSUED AT 1155 AM CDT MON OCT 26 2026
IN GENERAL, THE WEATHER SHOULD REMAIN ABOUT STATUS QUO FOR MOST
LOCATIONS FOR THE NEXT SEVERAL DAYS WITH DOMINATE LOW LEVEL RIDGING
ACROSS THE EASTERN CONUS STRETCHING INTO TEXAS. ONE CANNOT RULE OUT
AN ISOLATED SHOWER OR TWO ALONG THE SOUTHERN 2 TIERS OF COUNTIES
NEAREST THE COAST AND OFFSHORE THROUGH THURSDAY, BUT MOST OF THE
AREA SHOULD REMAIN DRY. ONE EXCEPTION, HOWEVER, COULD BE WEST AND
SOUTHWEST OF THE METRO AREA (MATAGORDA BAY-BRENHAM REGION) ON TUE-
WED. THIS WILL BE WHERE HIGHER MOISTURE AVAILABILITY WILL BE
SITUATED, AND WITH THE COMBINATION OF SOME HEATING AND WEAK PASSING
MID LEVEL DISTURBANCES, SCATTERED SHRA/TSTMS COULD BE INITIATED.
THERE WILL BE SOME INCREASED MID-UPPER CLOUDINESS AREAWIDE, SO
TEMPERATURES SHOULD BE A DEGREE OR THREE COOLER THAN WE'VE SEEN
THE PAST COUPLE DAYS.
HEADING INTO LATE WEEK AND INTO THE WEEKEND, MID LEVEL RIDGING
SHOULD BE SUPPRESSED FURTHER SOUTH AND EAST OF THE REGION. THIS
WILL SET UP A SOMEWHAT MESSY SOUTHWEST FLOW ALOFT WITH THE
POTENTIAL FOR SOME EMBEDDED IMPULSES TO TRACK ACROSS MEXICO INTO
PORTIONS TEXAS. TRAJECTORY AND TIMING OF THESE IMPULSES ARE
UNCERTAIN THIS FAR IN ADVANCE. MUCH OF THE LATEST DETERMINISTIC
GUIDANCE SEEMS TO TRACK A FAIR PORTION OF THESE DISTURBANCES JUST
TO THE NW/N OF THE REGION, BUT TIME WILL TELL. THINK THE ONGOING
20-35% POPS IN THE FCST WILL SUFFICE FOR MOST OF THE CWA FOR NOW.
