ISSUED AT 1200 AM CDT TUE OCT 13 2026
MIDNIGHT INFRARED SATELLITE IMAGERY AND SURFACE OBSERVATIONS
OUTLINED A STRONG COLD FRONT ARRIVING ALONG THE I-70 CORRIDOR.
THE COLD FRONT'S PROGRESS APPEARS TO BE WELL AHEAD OF MOST MODEL
PROJECTIONS, BUT CONSENSUS IS THE FRONTAL BOUNDARY WILL
DECELERATE DAYLIGHT TUESDAY IN THE FACE OF AN UNSEASONABLY WARM
BOUNDARY LAYER. 00Z NAM/ARW DEPICT THE FRONT NEAR US 50 AT
4 PM, BUT THE FRONT'S CURRENT QUICK PROGRESSION WILL NEED TO
SLOW SUBSTANTIALLY FOR THE NAM'S FORECAST FRONTAL POSITION TO
VERIFY. AT ANY RATE, STRONG CONVERGENCE IS EXPECTED NEAR THE
TRIPLE POINT INTERSECTION OF THIS FRONT AND THE DRYLINE,
SOMEWHERE OVER THE CENTRAL/SOUTHCENTRAL ZONES DURING THE
AFTERNOON. SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP
AFTER 4 PM, FAVORING THE SOUTHEAST ZONES, MAINLY SOUTHEAST OF
DODGE CITY. BULK SHEAR AND INSTABILITY WILL BOTH BE SUFFICIENT
TO SUPPORT A SUPERCELL STORM MODE, BUT CONVECTION IS EXPECTED TO
BE UNDERCUT QUICKLY BY THE ADVANCING COLD AIR INTO TUESDAY
EVENING. CURRENT OBSERVATIONS REVEAL AIR TEMPERATURES IN THE 30S
ACROSS MUCH OF THE NORTHERN PLAINS, AND FEEL MODELS MAY NOT BE
APPRECIATING THE MAGNITUDE OF THIS COLDER AIR MASS. AS SUCH, IT
MAY BE DIFFICULT TO ACHIEVE ANY SURFACE-BASED CONVECTION IN
KANSAS TODAY. LARGE HAIL, 1-2 INCHES IN DIAMETER, IS EXPECTED TO
BE THE PRIMARY THREAT TUESDAY AFTERNOON/EVENING, SOUTHEAST OF A
MEADE-DODGE CITY-LARNED LINE. WITH THE FRONT BISECTING SW KS, A
LARGE TEMPERATURE RANGE WILL RESULT TUESDAY AFTERNOON, RANGING
FROM 60S NORTH TO 90S SOUTH.
RISING SURFACE PRESSURES WILL CONTINUE TONIGHT INTO WEDNESDAY AS
COOL HIGH PRESSURE BUILDS SOUTHWARD ACROSS THE CENTRAL PLAINS.
MODELS FORECAST WIDESPREAD STRATUS AND DRIZZLE DEVELOPING
THROUGH WEDNESDAY MORNING, IN THE DEVELOPING WARM AIR ADVECTION
REGIME OVER THE COLD BOUNDARY LAYER. 00Z NAM REALLY LATCHES ONTO
THIS COLD SOLUTION, USUALLY THE BEST GUIDANCE FOR COLD AIR
WEDGING DOWN THE HIGH PLAINS. WITH A SATURATED BOUNDARY LAYER,
STRATUS OVERCAST, AND DRIZZLE, WITH NORTHEAST WINDS AND COLD
ADVECTION, NAM-BASED SOLUTIONS ARE UNSEASONABLY COLD, STRUGGLING
TO GET OUT OF THE 40S WEDNESDAY AFTERNOON. AFTER NEIGHBORING WFO
COORDINATION, LOWERED NBM FORECASTS SIGNIFICANTLY INTO THE 50S,
AND THIS IS PROBABLY STILL TOO WARM GIVEN UPSTREAM OBSERVATIONS
IN THE NORTHERN PLAINS TONIGHT.
HEAVY RAIN IS EXPECTED TO FOCUS ON WEDNESDAY NIGHT, AS THE
MIDLEVEL CLOSED CYCLONE EJECTS THROUGH COLORADO, AND STRONG
FORCING FOR ASCENT/DIFFLUENCE ALOFT SPREAD OVER SW KS. GLOBAL
MODELS ARE VERY WET WEDNESDAY NIGHT, WITH NBM POPS 90-100%,
AND RAIN AMOUNTS OF 1/2-1 INCH EXPECTED TO BE COMMON. SOME
ELEVATED INSTABILITY MAY GENERATE SOME SMALL HAIL WEDNESDAY
NIGHT, BUT LOCALLY HEAVY RAIN AND HYDROLOGY IMPACTS ARE THE MAIN
CONCERN.
THE STRONGEST COLD FRONT OF THE FALL SEASON SO FAR IS EXPECTED
THURSDAY, WITH STRONG NORTH WINDS. NBM WIND GRIDS LOOKED
SUFFICIENT, BUT ARE PROBABLY STILL TOO LOW, WITH GUSTS OF
40-45 MPH EXPECTED. AGAIN, TRIMMED THURSDAY TEMPERATURES FROM
THE NBM ALONG WITH NEIGHBORS, WITH 00Z GFS FORECASTING 850 MB
TEMPERATURES FALLING TO NEAR +5C AT DDC THURSDAY AFTERNOON.
STRONG 1040 MB CANADIAN HIGH PRESSURE WILL ARRIVE FRIDAY, WITH
DIMINISHING NORTH WINDS, AND AFTERNOON TEMPERATURES ONLY IN THE
50S, EVEN WITH FULL SUNSHINE. NEAR IDEAL RADIATIONAL COOLING IS
EXPECTED FRIDAY NIGHT, WITH THE FIRST FREEZE OF THE SEASON
EXPECTED SATURDAY MORNING. NBM TEMPERATURES SATURDAY MORNING ARE
TRENDING DOWN INTO THE LOWER 30S/NEAR FREEZING, AND UPPER 20S
ARE PROBABLE WHERE WINDS ARE LIGHT AND VARIABLE, AND IN OUR
TYPICALLY COLDEST LOCATIONS. A FREEZE WARNING IS EXPECTED TO BE
REQUIRED SATURDAY MORNING.
AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
ISSUED AT 1021 PM CDT MON OCT 12 2026
VFR CONDITIONS WILL PREVAIL THROUGHOUT THE TAF PERIOD FOR THE
AIRPORTS. SURFACE OBSERVATIONS SHOW COLD FRONT APPROACHING I-70
AT 03Z TUE, AND THIS COLD FRONT IS EXPECTED TO BE THROUGH HYS BY
THE BEGINNING OF THIS TAF PERIOD. NORTHEAST WIND SHIFTS, WITH
GUSTS UP 20-25 KTS, ARE ALSO MODELED TO OCCUR AROUND 00Z WED AT
KDDC AND KGCK. LBL WILL SEE THE COLD FRONT WIND SHIFT LAST,
AROUND 03Z WED. THE POSSIBILITY FOR CONVECTIVE STORMS WILL STAY
MAINLY EAST OF KDDC THIS TAF PERIOD, SO CONFIDENCE WAS TOO LOW
TO MENTION STORMS IN THE DDC TAF. JUST AFTER THIS TAF PERIOD,
HAVE HIGH CONFIDENCE OF POST FRONTAL IFR STRATUS AT ALL AIRPORTS
06-12Z WED.
DDC WATCHES/WARNINGS/ADVISORIES
NONE.
