NEAR TERM
(TONIGHT)
ISSUED AT 255 PM CDT WED MAY 27 2026
AS EXPECTED, SHOWERS AND THUNDERSTORMS BLOSSOMED ACROSS MUCH OF
THE AREA ALONG AND WEST OF I-65 FOR THE FIRST PART OF THE
AFTERNOON, WITH ADDITIONAL SHOWERS AND STORMS APPROACHING THE AREA
FROM THE S ACROSS CENTRAL AL. THIS TREND IS EXPECTED TO CONTINUE
THROUGH THE EVENING HOURS, AND THE CURRENT FORECAST HANDLES THIS
WELL.
OVERNIGHT LOWS WILL ONLY FALL INTO THE 65-70F RANGE WITH VERY
HUMID CONDITIONS EXPECTED. THOUGH CLEARING ISN'T EXPECTED
OVERNIGHT, LOW CLOUDS WILL LINGER AND SHOULD KEEP WIDESPREAD FOG
PRODUCTION TO REMAIN PATCHY AT BEST, BUT ANY ADDITIONAL CLEARING
WOULD ALLOW FOR MORE WIDESPREAD DEVELOPMENT.
SHORT TERM
(THURSDAY THROUGH SATURDAY)
ISSUED AT 950 AM CDT WED MAY 27 2026
AS ALLUDED TO ABOVE, THE PATTERN WON'T CHANGE MUCH THROUGH THE
REMAINDER OF THE WEEK, WITH DAILY CHANCES FOR SHOWERS AND STORMS
EACH DAY. SLIGHTLY HIGHER CHANCES FOR CONVECTION EXIST THIS
WEEKEND (ESPECIALLY SATURDAY W/~80% POPS) BEFORE A PATTERN SHIFT
OCCURS TO START THE NEW WORK WEEK.
THANKFULLY, THERE'S NO STRONG SIGNAL FOR SEVERE WEATHER, BUT THAT
SAID, A STRONG STORM OR TWO CAN'T BE RULED OUT THAT MAY PRODUCE
40MPH WINDS AND TORRENTIAL RAINFALL DURING THIS TIME PERIOD.
DAYTIME HIGHS WILL BE IN THE UPPER 70S/LOWER 80S EACH AFTERNOON,
WITH MOIST/SOUPY MORNINGS IN THE MIDDLE/UPPER 60S TO THE LOWER 70S
EACH DAY.
LONG TERM
(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1036 PM CDT TUE MAY 26 2026
RIDGING IN THE NORTHERN MIDWEST WILL MAINTAIN A BLOCKING PATTERN
THROUGH THE LONG TERM PERIOD. THE PLACEMENT OF THE RIDGE WILL ALLOW
SEVERAL SHORTWAVES TO RIDE ALONG ITS WESTERN PERIPHERY AND DROP SE
INTO THE TN VALLEY. AT THE SURFACE, CORRESPONDING HIGH PRESSURE IN
THE NORTHERN MIDWEST WILL INDUCE EASTERLY FLOW ALONG ITS BASE. THIS
WILL MAINTAIN A MUGGY AIRMASS AS 60-70 DEGREE DEWPOINTS AND ELEVATED
PWATS ARE PULLED IN FROM THE ATLANTIC COAST. ALL IN ALL, THE MUGGY
AIRMASS PAIRED WITH SEVERAL PASSING SHORTWAVES WILL AMOUNT TO
ADDITIONAL DAYS OF MEDIUM TO HIGH RAIN CHANCES OF ABOUT 50-80% EACH
AFTERNOON. WHILE THUNDER IS LIKELY WITH ANY SHOWERS, THERE ARE NO
STRONG SIGNALS FOR SEVERE WEATHER CURRENTLY DURING THIS PERIOD.
RATHER, WE WILL CONTINUE TO MONITOR FLOODING POTENTIAL. WITH HIGH
RAIN CHANCES IN PLACE ALL WEEK, ADDITIONAL RAIN IN THE LONG TERM MAY
LEAD TO COMPOUNDING FLOODING CONCERNS WITH ANY ADDITIONAL HEAVY
RAINFALL INCREASING THE CHANCES OF FLASH FLOODING AND RIVER FLOODING.
AVIATION
(00Z TAFS)
ISSUED AT 540 PM CDT WED MAY 27 2026
LIGHT TO MODERATE SHOWERS WILL CONTINUE TO MOVE NE ACROSS THE AREA
THROUGH ABOUT 06Z. THE CHANCE OF THUNDER IS LOW WITH THESE HOWEVER
IF A SHOWER MOVES DIRECTLY OVER THE TERMINAL, CEILINGS AND
VISIBILITIES COULD BRIEFLY LOWER. AROUND 09Z A LOW IFR TO LIFR
CLOUD DECK LOOKS TO MOVE INTO BOTH TERMINALS AND REMAIN THROUGH
MOST OF THE MORNING. CONDITIONS LOOK TO LIFT BACK TO VFR AROUND
16Z WITH ADDITIONAL LOW TO MEDIUM CHANCES OF SHOWERS TOMORROW
AFTERNOON. SUBSEQUENT TAF UPDATES WILL REFINE SHOWER CHANCES AND
TIMING.
