DISCUSSION
ISSUED AT 1212 PM CDT THU MAY 28 2026
AN OMEGA BLOCKING PATTERN IS EXPECTED TO SET UP OVER THE CONUS,
POTENTIALLY THROUGH MID-JUNE. THIS TYPE OF PATTERN TYPICALLY
BRINGS SUBSIDENCE AND HIGH PRESSURE TO THE CENTRAL AND SOUTHERN
PLAINS, INCLUDING DEEP SOUTH TEXAS, AS THE REGION IS EXPECTED TO
REMAIN SANDWICHED BETWEEN TWO LOW PRESSURE SYSTEMS TO THE EAST AND
WEST. THIS PATTERN WILL HELP KEEP CONDITIONS WARM AND RELATIVELY
RAIN FREE OVER THE NEXT WEEK. HIGH TEMPERATURES ARE GENERALLY
EXPECTED TO BE IN THE UPPER 80S AND LOW-TO-MID 90S THROUGHOUT THE
WEEK, WITH MOSTLY MINOR (LEVEL 1 OF 4) TO MODERATE (LEVEL 2 OF 4)
HEAT RISK EXPECTED.
SOME MINOR SHORTWAVE ACTIVITY COMING OFF THE TROUGH TO THE WEST
NEXT WEEK COULD CREATE ENOUGH INSTABILITY FOR A FEW ISOLATED TO
SCATTERED SHOWER/THUNDERSTORMS, PARTICULARLY ON TUESDAY AND
WEDNESDAY OF NEXT WEEK, ENHANCED BY THE DIURNAL HEATING CYCLE AND
THE SEA BREEZE. CHANCES REMAIN LOW TO MODERATE (AROUND 20 TO 50%)
THROUGHOUT DEEP SOUTH TEXAS.
