DISCUSSION
ISSUED AT 240 PM CST TUE DEC 23 2025
FOR MUCH OF THE AREA ACROSS NORTHEASTERN KANSAS, WARM AND SUNNY
CONDITIONS HAVE PUSHED TEMPERATURES INTO THE UPPER 50S AND LOW 60S.
THAT SAID, THOSE ACROSS EAST-CENTRAL KANSAS HAVE SEEN LINGERING
FOGGY CONDITIONS. THIS HAS KEPT TEMPERATURES IN THE MID 50S. THE
OVERALL SYNOPTIC PATTERN IS DOMINATED BY THE DEEPENING MID-LEVEL
RIDGE OVER THE SOUTHERN PLAINS THAT IS PROGGED TO PERSIST THROUGH
THE HOLIDAY WEEK. THIS WILL LEAD TO NEAR-RECORD TEMPERATURES FOR THE
NEXT SEVERAL DAYS. MORE ON THIS LATER. BY TONIGHT, MORE DENSE FOG
WILL BUILD BACK ACROSS THE AREA. WITH 40-50 DEGREE DEWPOINTS
OVERSPREADING MUCH OF THE SOUTHEASTERN KANSAS AND WEAK EASTERLY
WINDS, THE BL OVERNIGHT WILL REMAIN NEAR SATURATED, ESPECIALLY
ACROSS AREAS THAT DID NOT HAVE A CHANCE TO WARM MUCH THIS AFTERNOON.
LOW LEVEL PRESSURE GRADIENTS NORTH OF A STALLED BOUNDARY WILL REMAIN
WEAK OVERNIGHT. FOG DEVELOPMENT WILL BEGIN ACROSS SOUTHERN PORTIONS
OF THE CWA LATER THIS EVENING, QUICKLY REDUCING VISIBILITIES TO LESS
A MILE AND THEN PAST A QUARTER-MILE AFTER MIDNIGHT. THERE WILL BE
SOME WEAK ISENTROPIC LIFT WITHIN THE LOWEST 850MB THROUGH THE
OVERNIGHT HOURS THAT MAY ALSO HELP SQUEEZE OUT SOME DRIZZLE, BUT
BEST CHANCES FOR THIS REMAIN ACROSS FAR EAST AND NORTHEASTERN KANSAS
WHERE LIFT APPEARS THE BEST. ALL THIS SAID, CONFIDENCE WAS HIGH
ENOUGH (70%+) TO ISSUE ANOTHER DENSE FOG ADVISORY FOR AREAS OF
CENTRAL AND EAST- CENTRAL KANSAS FROM MIDNIGHT TO 11 AM WEDNESDAY
MORNING. THIS MAY NEED TO BE EXPANDED FURTHER NORTH IF CONFIDENCE IN
WIDESPREAD FOG INCREASES OVER THE COMING HOURS, BUT OPTED TO WAIT.
THERE MAY BE SOME TIMES OVERNIGHT WHERE 10-15MPH WINDS AT THE TOP OF
THE BL SCATTER FOG TO LOW STRATUS, BUT GIVEN THE DEEP SATURATION
THROUGH 925MB, NOT THINKING THIS WILL THROW TOO MUCH OF A WRENCH IN
FOG PRODUCTION. SREF GIVES AREAS SOUTH OF I-70 HAVE A 40-60%+ CHANCE
OF SEEING VISIBILITIES BELOW 1/2 MILE WHILE SOME CAM PROBABILITIES
INCREASE THAT TO 70%+. THIS HELPED TO FURTHER INCREASE CONFIDENCE IN
THE DENSE FOG ADVISORY. FOG SHOULD BEGIN TO BURN OFF BY THE LATE
MORNING HOURS WEDNESDAY. COULD SEE SOME STRATUS LINGER INTO THE
AFTERNOON THAT COULD IMPACT TEMPERATURES A BIT, SO OPTED TO LOWER
MAXTS FOR WEDNESDAY BY A FEW DEGREES.
NEAR-RECORD TEMPERATURES WILL STILL BE EXPECTED FOR THURSDAY THROUGH
SATURDAY AS THE UPPER-LEVEL RIDGE FURTHER EXPANDS AND DEEPENS OVER
THE CENTRAL PLAINS. A WEAK SURFACE BOUNDARY SLIDES ACROSS THE AREA
THURSDAY NIGHT INTO FRIDAY, BUT IT DOES NOT BRING ANY COOLER LOW
LEVEL TEMPERATURE PROFILES, SO NOT EXPECTING THIS TO IMPACT
AFTERNOON HIGHS FRIDAY OR SATURDAY. THE BIGGEST CHANGE COMES SUNDAY
AS A DIGGING ARCTIC UPPER LOW PHASES WITH A LOW OVER THE SOCAL
REGION. AS THIS TROUGH EJECTS ACROSS THE ROCKIES EARLY SUNDAY, A
STOUT BLAST OF COLD AIR FILTERS IN BEHIND A SURFACE BOUNDARY THROUGH
THE DAY SUNDAY. HIGH TEMPERATRES MONDAY MAY BE REALIZED IN THE
MORNING WITH MINIMAL WARMING THROUGH THE DAY. LUCKILY, ANY
PRECIPITATION CHANCES STAY SOUTH OF THE AREA. TEMPERATURES APPEAR TO
WARM UP A BIT BY EARLY NEXT WEEK, CLOSER TO AVERAGE WITH DRY WEATHER
PERSISTING.
AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
ISSUED AT 1134 AM CST TUE DEC 23 2025
FOG HAS CLEARED ACROSS THE TERMINALS IN THE PAST FEW HOURS WITH
VFR CONDITIONS AND LIGHT NORTHEASTERLY WINDS THROUGH THE
AFTERNOON. SOME FLIGHT RESTRICTIONS WILL MOVE IN AGAIN LATER
THIS EVENING AS THE BL SATURATES AGAIN, USHERING IN ANOTHER
CHANCE FOR FOG AND IFR (POSSIBLE LIFR) CEILINGS. CONFIDENCE IN
FOG IS A BIT LOWER THAN THIS MORNING AS THERE MAY BE SOME MIXING
AT THE TOP OF THE BL THAT HELPS TO KEEP THINGS AS LOW STRATUS.
KEPT MENTION OF IFR VIS AT ALL SITES WITH IFR CIGS AND CAN WORK
THAT DOWN IF CONFIDENCE IN FOG INCREASES. FOR THE END OF THE
TAF, THINGS SHOULD SCATTER OUT A BIT BY LATE WEDNESDAY MORNING,
BUT THERE ARE SOME FORECAST SOUNDINGS THAT KEEP A DECK OF
STRATUS THROUGH MUCH OF THE AFTERNOON WEDNESDAY. OPTED TO GO
WITH A SCATTERED GROUP FOR THE LOW CEILINGS AND WILL CONTINUE TO
MONITOR CHANGES AND THE NEED FOR A CIG RESTRICTION WEDNESDAY.
