SHORT TERM
(TONIGHT THROUGH THURSDAY NIGHT)
ISSUED AT 1130 PM CDT TUE MAY 26 2026
ABUNDANT MOISTURE REMAINS IN PLACE ACROSS THE REGION TONIGHT AS
THE WEATHER PATTERN HAS BEEN SLOW TO EVOLVE. A WEAKENING SHORTWAVE
TROUGH IS TO OUR NORTHWEST WITH RIDGING TO OUR SOUTHEAST, SO THIS
HAS KEPT SOUTHWEST FLOW ALOFT OVER THE AREA WITH SOUTHERLY LOW-
LEVEL FLOW PROVIDING CONTINUED MOISTURE ADVECTION. THANKFULLY PWS
HAVE DECREASED SOMEWHAT THIS EVENING (1.5-1.6") AND BEST FORCING
HAS MOVED TO OUR NORTH. TONIGHT SHOULD BE LESS ACTIVE AND THIS
SHOULD CONTINUE INTO TOMORROW, THOUGH DIURNAL HEATING WILL LEAD TO
SCATTERED AFTERNOON SHOWERS AND A FEW STORMS. NO ORGANIZED
FLOODING OR SEVERE WEATHER IS EXPECTED. A MOISTURE GRADIENT
APPEARS TO DEVELOP ON THURSDAY AS DRIER AIR BUILDS TO OUR
NORTHEAST. THIS SHOULD RESULT IN MOST CONVECTION REMAINING SOUTH
OF I-40, BUT ANOTHER DAY OF SCATTERED SHOWERS AND A FEW STORMS IS
EXPECTED NONETHELESS.
LONG TERM
(FRIDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 1130 PM CDT TUE MAY 26 2026
AN OMEGA BLOCK WILL REMAIN IN PLACE ACROSS THE CONUS BY THE END OF
THE WEEK WITH HIGH PRESSURE AND DRIER AIR LOOMING JUST TO OUR
NORTH. A NORTHWEST TO SOUTHEAST MOISTURE AXIS REMAINS EVIDENT ON
GUIDANCE AND THIS WILL BE MORE THAN SUFFICIENT TO FOSTER
ADDITIONAL RAIN/STORM CHANCES INTO THE WEEKEND. PWS IN THIS
MOISTURE AXIS ARE PROGGED TO RUN 1.6-1.8" WHICH IS ABOVE THE 90TH
PERCENTILE THIS TIME OF YEAR. HOWEVER, MEDIUM-RANGE GUIDANCE
CONTINUES TO DEPICT THE HIGH PRESSURE/DRIER AIR MASS GRADUALLY
SHIFTING SOUTH BY SUNDAY WHICH LEADS TO DECREASING POPS THAT WILL
CONTINUE INTO EARLY NEXT WEEK. THIS SHOULD LEND TIME TO DRY OUT
AFTER REPEATED WAVES OF DROUGHT-IMPROVING RAINFALL ACROSS MIDDLE
TENNESSEE.
