UPDATED THE AVIATION DISCUSSION FOR THE 18Z TAF ISSUANCE.
UPDATE ISSUED AT 1024 AM CDT THU JUL 23 2026
FORECAST REMAINS ON TRACK, WITH SCATTERED RAIN SHOWERS MOVING
INTO SOUTH CENTRAL SD. WEBCAMS ARE SHOWING THESE SHOWERS AS
MORE ISOLATED SPRINKLES AT THE MOMENT, SO SPRINKLES WERE ADDED
INTO THE GRIDS TO COVER WHAT IS HAPPENING. THESE RAIN SHOWERS
AND SPRINKLES WILL CONTINUE INTO THE AFTERNOON. A FEW RUMBLES
OF THUNDER WILL BE POSSIBLE, THOUGH IT LOOKS TO MAINLY STAY AS
RAIN SHOWERS.
DISCUSSION
ISSUED AT 106 AM CDT THU JUL 23 2026
AS OF 1 AM CDT, TEMPERATURES AROUND THE AREA ARE IN THE LOW 60S WITH
WINDS OUT OF THE SOUTHEAST AROUND 10 MPH. THERE IS ONCE AGAIN A
CHANCE OF SHOWERS ACROSS SOUTH CENTRAL SD TODAY. THE CHANCE OF
ACCUMULATIONS HIGHER THAN 0.10" IS AROUND 45 TO 75% ALONG AND SOUTH
OF I-90. THERE COULD BE A WEAK THUNDERSTORMS OR TWO MIXED IN BUT
SEVERE STORMS ARE NOT EXPECTED. HRRR SMOKE IS STILL SHOWING A
MODERATE CONCENTRATION OF SMOKE OVER OUR AREA TODAY AND FRIDAY. THIS
IS MAINLY ALOFT BUT THERE COULD BE SOME AT THE SURFACE AND
COULD CAUSE SOME SLIGHT DECREASES TO VISIBILITY. THE MAJORITY OF
MODELS ARE SHOWING A LAYER OF INCREDIBLY LOW STRATUS ACROSS
MOST OF THE FORECAST AREA LATER THIS EVENING THROUGH FRIDAY
MORNING. SOME SHORT TERM MODELS ARE ALSO SHOWING MUCH HIGHER
CEILINGS, INCLUDING SOME THAT HAVE SWITCHED CAMPS FROM RUN TO
RUN, SO, CONFIDENCE IS LOW ON HOW LOW CLOUDS WILL GET.
SPC HAS HIGHLIGHTED NORTHERN SD IN A MARGINAL RISK (LEVEL 1 OUT OF
5) FOR SEVERE STORMS FRIDAY AFTERNOON ACROSS NORTHERN SD.
CONFIDENCE IS LOW THAT THESE STORMS WILL ACTUALLY FORM. THERE
ARE SOME CAMS THAT SHOW STORMS OVER NORTH CENTRAL SD AND SOME
THAT SHOW STORMS OVER NORTHEAST SD. EITHER WAY, CURRENT
PRECIPITATION CHANCES ARE 30% OR LESS. HEAT RETURNS FRIDAY OVER
CENTRAL SD AND THEN SATURDAY AND SUNDAY FOR THE ENTIRE FORECAST
AREA. HIGHS MAY BE A LITTLE HIGH OVER NORTHEASTERN SD WHERE
HUMIDITY IS HIGHER BUT SHOULD BE FAIRLY OK OVER CENTRAL SD.
CURRENT FORECAST OVER CENTRAL SD IS IN THE MID 100S. THIS MAY
NECESSITATE A HEAT ADVISORY. KEEP AN EYE ON THE FORECAST FOR ANY
UPDATES CONCERNING THIS. HIGHS OVER NORTHEAST SD AND WEST
CENTRAL MN MIGHT BE CLOSER TO THE LOW 90S THAN THE CURRENTLY
FORECAST MID 90S. TEMPERATURES MODERATE A BIT FOR NEXT WORK
WEEK. DURING THIS HEAT WAVE, PRECIPITATION CHANCES ARE VERY
LIMITED. WE ARE, HOWEVER, SEEING A SIGNAL FOR SOME POSSIBLE
PRECIP MID NEXT WEEK.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1211 PM CDT THU JUL 23 2026
TERMINALS KABR,KATY,KPIR,KMBG
WHILE THERE ARE SOME LOW TO MID LEVEL CLOUDS MOVING OVER CENTRAL AND
NORTHEASTERN SD TODAY, VFR CONDITIONS WILL STICK AROUND. KPIR COULD
SEE SLIGHTLY LOWER CONDITIONS DURING THE AFTERNOON AS THERE COULD
BE SOME RAIN SHOWERS MOVING OVER. THERE ARE CHANCES FOR RAIN SHOWERS
THROUGH THE AFTERNOON BEFORE THING START TO CLEAR UP. THERE WILL
ALSO BE SOME LOWER CLOUDS THAT MOVE IN EARLY FRIDAY MORNING OVER
KABR AND KATY, WHICH COULD CAUSE MVFR TO IFR CONDITIONS FOR A FEW
HOURS. THERE WILL BE SOME WILDFIRE SMOKE COMING IN ALOFT, WHICH
COULD CAUSE SOME HAZY SKIES AND REDUCE CEILINGS SLIGHTLY. MOST OF
THE SMOKE SHOULD STAY ALOFT AND NOT REDUCE VISIBILITIES AT THE
SURFACE. SOUTHERLY WINDS THIS AFTERNOON COULD BE GUSTING UP TO 20-25
KTS OVER ALL TERMINALS. THE WINDS WILL CALM SLIGHTLY TONIGHT BEFORE
SHIFTING TO BE FROM THE SOUTH SOUTHWEST, WHICH COULD GUST UP TO 20
KTS OVER KATY FRIDAY MORNING.
