THE SYNOPTIC PATTERN REMAINS VIRTUALLY UNCHANGED WITH AN UPPER-LEVEL
HIGH PRESSURE SYSTEM OVER TEXAS AND A DEEP TROUGH SITUATED OVER THE
EASTERN GREAT LAKES REGION. CURRENTLY SHOWERS AND WEAK STORMS HAVE
RIDDEN NEAR THE CO/KS BORDER WITH SOME VERY LIGHT SHOWERS IN THE
THREE WESTERN-MOST COUNTIES. SURFACE ANALYSIS HAS A WEAK BOUNDARY IN
EASTERN COLORADO THAT THE SHOWERS MAY HAVE FIRED ALONG. CAMS HAVE
BEEN PERSISTENT WITH CONVECTION CONTINUING ACROSS THE CWA THROUGH THE
OVERNIGHT HOURS, BUT VARYING WILDLY IN LOCATION AND EXPANSE. OLDER
MODEL RUNS, AS WELL AS THE LATEST NAMNST RUN, HAS HAD MOST OF THE
PRECIPITATION TRACKING ACROSS MORE CENTRAL KS. NEWER RUNS HAS MORE
OF THE CONVECTION RIDING NEAR THE OK/KS BORDER. SOME NEW DEVELOPMENT
MAY TAKE PLACE INTO THE MORNING HOURS INTO CENTRAL KANSAS. SOME
FOG/LOW STRATUS MAY DEVELOP THIS MORNING, BUT ENSEMBLE CHANCES ARE
VERY ISOLATED. HIGHS ARE EXPECTED TO BE IN THE 70S OUT EAST AND 80S
OUT WEST.
THE MAIN FOCUS OF THE FORECAST HAS BECOME THE PRECIPITATION
POTENTIAL TONIGHT INTO TOMORROW MORNING. CAMS HAVE HELD FIRM IN A
DEVELOPMENT OF STORMS FROM AROUND SCOTT CITY DOWN TO MEDICINE LODGE.
SLIGHT DISCREPANCIES EXIST IN EXACT PLACEMENT, BUT THE OVERALL SIGNAL
HAS BEEN CONSISTENT OVER THE PAST FEW DAYS. WITH LITTLE IN THE
ENVIRONMENT SUPPORT OF DEEP AND STRONG CONVECTION, THE ONLY THREAT OF
THESE STORMS IS LIGHTNING AND RAINFALL. CURRENTLY IT CONTINUES TO
LOOK LIKE THE LINE WILL MOVE PERPENDICULAR ENOUGH TO THE AXIS OF
PRECIPITATION THAT HEAVY RAINFALL WILL NOT CONTINUE REDEVELOPING
OVER A CONSTANT AREA ELIMINATING MUCH OF THE THREAT FOR WIDESPREAD
FLOODING CHANCES. THAT SAID, SOME AREAS COULD SEE STORMS TRAIN
OVERHEAD AND PRODUCE POCKETS OF VERY HEAVY RAINFALL. MOST OF THE
RAINFALL IS EXPECTED TO FALL EAST OF HIGHWAY 283 WITH THE BEST
CHANCES FOR FLOODING ACROSS THE FAR EASTERN ZONES INCLUDING HAYS AND
PRATT. ENSEMBLES HAVE A REASONABLE RANGE OF AROUND 1-1.5" IN THE
EAST. THE WPC HAS MOST OF SW KANSAS IN A SLIGHT RISK FOR EXCESSIVE
RAINFALL AT >15% CHANCE TO SEE FLASH FLOOD CONDITIONS. AGAIN THIS
THREAT, IF IT OCCURS, WOULD BE IN VERY LOCAL/ISOLATED POCKETS.
OUTSIDE OF THE FORECASTS FOCUS ON RAINFALL WEDNESDAY NIGHT, THE WEEK
AHEAD IS EXPECTED TO BE PLEASANT WITH HIGHS FORECAST IN THE 70S INTO
NEXT WEEK. MULTIPLE ROUNDS OF PRECIPITATION ARE STILL EXPECTED TO BE
POSSIBLE. ENSEMBLES HAVE FRIDAY, SATURDAY, AND SUNDAY NIGHTS ALL
WITH AREAS ABOVE A 25% CHANCE FOR RAIN. MOST OF THIS IS WEST OF
HIGHWAY 283 AND DURING THE OVERNIGHT HOURS. A SEVERE THREAT IS NOT
CURRENTLY ANTICIPATED AND RAINFALL SHOULD BE LIGHT ENOUGH AS TO NOT
EVOKE APPARENT FLOODING CONCERNS THIS FAR OUT. SOME UNCERTAINTY
REMAINS ON MORE SPECIFIC DETAILS REGARDING AMOUNTS AND LOCATIONS,
BUT ENSEMBLES HAVE TOTALS FOR THE 3 DAYS WELL BELOW ONE INCH. THE
MAJORITY OF THIS RAINFALL IS EXPECTED IN THE FIRST ROUND LATE FRIDAY
NIGHT.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 530 AM CDT WED AUG 27 2025
LOW CEILINGS HAVE REDUCED LBL AND GCK TO LOWERED FLIGHT CONDITIONS
EARLY THIS MORNING. SOME REPRIEVE IS EXPECTED AROUND 17Z BEFORE THEY
RETURN LATER IN THE PERIOD CONVECTION. HAYS MAY SEE LIGHT SHOWERS
AROUND THAT SAME TIME, BUT THERE IS HIGH UNCERTAINTY WARRANTING A
TEMPO GROUP INSTEAD OF PREVAILING. ALL SITES HAVE A >45% CHANCE FROM
ENSEMBLES TO SEE SHOWERS/STORMS AROUND 1-3Z, AND MUCH OF CONVECTION
MAY BE STRONG ENOUGH TO GENERATE LIGHTNING. EXACT TIME AND EXTENT OF
THE SHOWERS/STORMS HOLDS SOME UNCERTAINTY, BUT THE SIGNAL FOR
WIDESPREAD PRECIPITATION IS LARGE. REGARDLESS IT IS ANTICIPATED THAT
THE PRECIPITATION WILL BRING LOWER CEILINGS AND LOWER FLIGHT
CONDITIONS.
DDC WATCHES/WARNINGS/ADVISORIES
NONE.
