DISCUSSION
ISSUED AT 1244 AM CDT MON SEP 14 2026
LATE NIGHT WATER VAPOR IMAGERY AND RAP OBJECTIVE ANALYSIS SHOWED
QUITE A ROBUST SHORTWAVE TROUGH CENTERED OVER IDAHO INTO WESTERN
MONTANA WITH BROAD SOUTHWEST FLOW IN THE MID-UPPER TROPOSPHERE
ACROSS MUCH OF THE ROCKIES INTO ADJACENT NORTHERN AND CENTRAL HIGH
PLAINS. THIS PATTERN HAS SHUNTED THE EFFECTIVE NORTH AMERICAN
MONSOON CIRCULATION TO THE EAST ACROSS MUCH OF NEW MEXICO INTO
COLORADO, WITH THE NORTHERN PORTION OF THE SUBTROPICAL MOIST
CIRCULATION PATTERN BECOMING INFUSED WITH THE POLAR SYSTEM MOVING
IDAHO AND MONTANA.
THE POLAR SYSTEM UP NORTH WILL MOVE ACROSS MONTANA INTO THE WESTERN
DAKOTAS BY MONDAY NIGHT, AND AN ASSOCIATED POLAR COLD FRONT WILL
PUSH SOUTH ACROSS NEBRASKA INTO NORTHWESTERN KANSAS BY MONDAY NIGHT.
A SUB-1000MB SURFACE LOW IS LIKELY TO DEVELOP OUT OF A BROAD LEESIDE
TROUGH, WITH INCREASING BOUNDARY LAYER CONVERGENCE ALONG THE LEE
TROUGH AND ESPECIALLY IN VICINITY OF SURFACE LOW. THUS, THE BEST
FOCUS FOR LATE AFTERNOON AND EVENING THUNDERSTORMS WILL BE OUT WEST
ACROSS FAR WESTERN KANSAS. THE MAJORITY OF CAMS ARE LINED UP FAIRLY
WELL WITH CONVECTIVE SIGNAL ALL ALONG THE SURFACE TROUGH, AND USING
HREF ENSEMBLE PROBABILITY OF ECHO TOPS > 45 KFT WOULD SUPPORT THE
NOTION FOR AT LEAST MARGINALLY SEVERE STORMS WITH ISOLATED TO WIDELY
SCATTERED 60+ MPH WIND GUSTS POSSIBLE. THE STRENGTH OF THE
CONVECTION WILL BE TIED FAIRLY CLOSELY TO THE DIURNAL CYCLE WITH
SEVERE WIND RISK DIMINISHING AFTER SUNSET.
MONDAY WILL ALSO LIKELY BE THE LAST UPPER 90S/NEAR 100 DEGREE DAY
FOR MOST OF SOUTHWEST KANSAS AHEAD OF THE FRONT, AS TUESDAY FORECAST
TEMPERATURES WILL BE QUITE A BIT LOWER, ESPECIALLY NORTH OF THE
ARKANSAS RIVER (I.E. DIGHTON HIGHS OF 97F MONDAY, 74F TUESDAY). THE
FRONT WILL LIKELY BISECT KANSAS FROM SOUTHWEST TO NORTHEAST, AND BY
MID TO LATE AFTERNOON, THERE SHOULD BE ANOTHER ROUND OF LOOSELY
ORGANIZED THUNDERSTORM ACTIVITY, MAINLY FOCUSED ON OUR EASTERN AND
SOUTHEASTERN COUNTIES.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
ISSUED AT 544 AM CDT MON SEP 14 2026
VFR CONDITIONS WILL PREVAIL IN VICINITY OF ALL TAF SITES THROUGH EARLY
EVENING. THUNDERSTORMS ARE THEN EXPECTED TO DEVELOP ALONG AND AHEAD
OF A COLD FRONT APPROACHING FROM THE NORTHWEST, POTENTIALLY AFFECTING
THE VICINITY OF KGCK AND KLBL GENERALLY AFTER 00-02Z. LIGHT SOUTHERLY
WINDS THROUGH MID-MORNING ARE FORECAST TO INCREASE 25 TO 35KT WITH
GUSTS UP TO 45KT THIS AFTERNOON AS A LEE SIDE TROUGH OF LOW PRESSURE
STRENGTHENS IN EASTERN COLORADO AHEAD OF THE AFOREMENTIONED APPROACHING
COLD FRONT, THEN SUBSIDE THIS EVENING WITH LOSS OF DAYTIME HEATING.
DDC WATCHES/WARNINGS/ADVISORIES
