DISCUSSION
(TODAY THROUGH TUESDAY)
ISSUED AT 1239 AM CDT WED MAY 13 2026
AS OF 1245 CDT, CONDITIONS ARE QUIET AND CALM. TEMPS ARE MOSTLY IN
THE 60S, WITH NEAR MATCHING DEWPOINTS. THANKS TO THAT, THE CLEAR
SKIES, AND THE CALM WINDS, SOME AREAS WILL BE SUSCEPTIBLE TO FOG
DEVELOPMENT DURING THE OVERNIGHT HOURS.
AT THE SURFACE, THE HIGH PRESSURE THAT BROUGHT SLIGHTLY DRIER
CONDITIONS WILL DRIFT OFF AFTER ANOTHER WEAK AND DRY FRONT QUICKLY
SWEEPS ACROSS. THESE FEATURES WILL DEPART THE AREA BY LATE THURSDAY
INTO FRIDAY, WITH SOUTHERLY FLOW RETURNING. ALOFT, FLOW WILL REMAIN
NORTHWESTERLY UNTIL THE RIDGE FLATTENS GOING INTO FRIDAY. NEAR ZONAL
FLOW WILL NOT PERSIST FOR TOO LONG, AS AN UPPER RIDGE STRENGTHENS
OVER THE GULF AND INTO THE ATLANTIC OVER THE NEXT WORK WEEK. ALONG
WITH THIS, AN UPPER TROUGH WILL TAKE SHAPE OVER THE WESTERN CONUS
BEFORE PROGRESSING EASTWARD EARLY TO MID NEXT WEEK.
FROM TODAY THROUGH THE REST OF THE WEEK, A GRADUAL WARMING TREND
WILL KICK OFF WITH MAXTS GETTING INTO THE MID 80S TO LOWER 90S AND
MINTS GOING FROM THE LOW 60S TO 70S BY THE END OF THE WEEK. TD'S
WILL ALSO BE ON THE RISE, WITH THE AFOREMENTIONED RETURN OF
SOUTHERLY FLOW. LITTLE TO NO RAIN CHANCES EXPECTED UNTIL SUNDAY,
THEN DAILY ISOLATED TO SCATTERED CHANCES FROM THERE.
