KEY MESSAGES
- ONE ROUND OF STRONG-SEVERE STORMS CLIPPED OUR FAR EAST
BRIEFLY, BUT AS SINCE PUSHED FURTHER EAST...AND FOCUS NOW
TURNS TO OUR WEST, WHERE ANOTHER CLUSTER OF STRONG-SEVERE
STORMS LOOKS TO WORK INTO THE AREA. A SEVERE THUNDERSTORM
WATCH REMAINS IN EFFECT FOR MOST OF OUR COUNTIES THROUGH 10
PM. LARGE HAIL/DAMAGING WINDS LOOK TO BE THE MAIN THREAT.
- FORECAST DRIES OUT AFTER MIDNIGHT TONIGHT, AND REMAINS DRY
THROUGH MONDAY NIGHT. HIGHS ON MONDAY LOOK TO REACH INTO THE
80S.
- AN AREA OF LOW PRESSURE SLOWLY MOVING IN FROM THE NW AND THEN
STICKING AROUND THROUGH THE END OF THE WEEK KEEPS
PRECIPTIATION CHANCES IN THE FORECAST TUESDAY-SATURDAY. THE
OVERALL BEST CHANCES ARE IN THE TUESDAY EVENING-WEDNESDAY
NIGHT TIME FRAME WITH THE SYSTEM'S INITIAL ARRIVAL. SOME
STRONG-SEVERE STORMS ARE NOT OUT OF THE QUESTION TUE-TUE
NIGHT.
- HIGHS ON TUESDAY ARE ONCE AGAIN IN THE 80S, WITH HIGHS THE
REST OF THE WEEK BACK IN THE 70S WITH THE PRECIPITATION
CHANCES LINGERING IN THE FORECAST.
DISCUSSION
ISSUED AT 351 PM CDT SUN SEP 14 2025
CURRENTLY THROUGH TONIGHT...
SHOWERS AND STORMS ARE RIDING ALONG BOTH THE WESTERN AND EASTERN
FRINGES OF THE FORECAST AREA THIS AFTERNOON...AND ESPECIALLY FOR
WESTERN AREAS, THAT THREAT WILL CONTINUE TO INCREASE THE REST
OF THIS AFTERNOON/EVENING. LOOKING ALOFT, UPPER AIR AND
SATELLITE DATA SHOWING AN AREA OF LOW PRESSURE SET UP OVER
WESTERN NE...MAKING ONLY A LITTLE ENEWARD PROGRESS THANKS TO A
WELL AMPLIFIED RIDGE OF HIGH PRESSURE EXTENDING NORTH FROM THE
WESTERN GULF COAST INTO THE WESTERN GREAT LAKES. AT THE SURFACE,
THE FORECAST AREA HAS BEEN SITTING UNDER INCREASING SSERLY
WINDS, EAST OF THE MAIN FRONTAL BOUNDARY WHILE LIES ACROSS
WESTERN PORTIONS OF KS/NE INTO THE DAKOTAS. IT'S TAKEN A WHILE
FOR SPEEDS TO PICK UP, PARTLY DUE TO THE PLENTIFUL CLOUD COVER
THAT HAD BEEN IN PLACE...SEEING MORE GUSTS AROUND 20-25 MPH,
ESPECIALLY ACROSS THE WESTERN HALF OF THE FORECAST AREA. THE DAY
STARTED OUT WITH OVERCAST SKIES FOR MOST LOCATIONS, AND THOUGH
THAT MID-UPPER LEVEL CLOUD COVER HAS BEEN PUSHING FURTHER EAST
WITH TIME, LOWER LEVEL CU HAS BEEN FILLING IN BEHIND...SO EVEN
NOW MOST SPOTS ARE STILL AT LEAST PARTLY CLOUDY. EVEN WITH THE
CLOUDS LINGERING AROUND, BY THE TIME IT'S ALL SAID AND DONE,
HIGHS DON'T LOOK TO END UP WORKING OUT TOO BAD...MOST SPOTS ARE
IN THE MID- UPPER 70S.
AS FAR AS STORM CHANCES GO...THE ACTIVITY CURRENTLY ALONG OUR
EASTERN FRINGE IS EXPECTED TO CONTINUE PUSHING ENE THE REST OF
THIS AFTERNOON, WITH OUR MAIN FOCUS TURNING TO AREAS JUST OFF
TO OUR WEST. THIS ACTIVITY IS TIED CLOSER TO THE MAIN UPPER
LEVEL LOW/TROUGH...AND MODELS REMAIN IN FAIRLY GOOD AGREEMENT
SHOWING THE CURRENT CLUSTER RUNNING ROUGHLY FROM BBW
SOUTHWESTWARD TO GLD CONTINUING ON AN EASTWARD MARCH IN THE
COMING HOURS. SPC MESOANALYSIS PAGE CONTINUES TO SHOW THAT THE
MAIN AXIS OF INSTABILITY (MLCAPE VALUES AROUND 1500 J/KG) LYING
THROUGH THE WESTERN PORTIONS OF OUR FORECAST AREA, WHERE THERE
HAS BEEN MORE SUN...BUT THE MAIN AXIS OF BETTER DEEPER LAYER
SHEAR AROUND 40KTS IS OFFSET FROM THAT A BIT, MORE CENTERED
THROUGH THE EASTERN PORTIONS OF THE FORECAST AREA. THAT BEING
SAID...WHILE NOT IDEALLY LINED UP, THERE IS SUFFICIENT
OVERLAPPING THAT ANY STORM THAT IMPACTS THE FORECAST AREA WILL
HAVE THE POTENTIAL TO BE STRONG- SEVERE...ESPECIALLY OVER
WESTERN AREAS WHERE ALONG WITH THE INSTABILITY, LAPSE RATES ARE
BETTER...AND THE SPC DAY 1 SLIGHT/MARGINAL RISK AREAS HAVE
REMAINED UNCHANGED THROUGH THE DAY.
THIS THREAT WILL CONTINUE ON THROUGH THE EVENING HOURS...WITH
MODELS SHOWING THE STRENGTH AND OVERALL COVERAGE DIMINISHING
AS THE UPPER LEVEL FORCING MAKES MORE OF A NORTHWARD PUSH AND
WITH THE LOSS OF DAYTIME HEATING. KEPT A SLIGHT CHANCE (20
PERCENT) OF PRECIPITATION GOING THROUGH JUST AFTER MIDNIGHT,
THEN THE REST OF THE NIGHT LOOKS DRY.
MONDAY...
OVERALL NO NOTABLE CHANGES WERE MADE TO THE FORECAST FOR THE
FIRST DAY OF THE NEW WORK WEEK...WHICH REMAINS DRY. MODELS
CONTINUE TO SHOW A MESSY, BLOCKED PATTERN ACROSS THE CONUS...LOW
PRESSURE REMAINS ANCHORED OVER THE SERN CONUS, WITH A COUPLE
AREAS OF LOW PRESSURE OVER THE NORTH CENTRAL PLAINS THROUGH THE
PAC NW...WITH RIDGING SANDWICHED IN BETWEEN. WINDS REMAIN
SOUTHERLY AROUND 10-15 MPH...HIGHS CLIMBING INTO THE MID-80S FOR
MOST.
TUESDAY ON THROUGH THE WEEK...
THE WEATHER FOR THE REST OF THE WEEK WILL CONTINUE TO BE DRIVEN
BY AN EVEN SLOWER THAN USUAL MOVING UPPER LEVEL
PATTERN...KEEPING PLENTY OF CHANCES FOR PRECIPTIATION AROUND THE
REGION. MODELS ARE IN GENERALLY GOOD AGREEMENT LOOKING AT THE
BIGGER PICTURE...SHOWING THE UPPER LEVEL ENERGY CURRENTLY IN THE
PAC NW REGION EVENTUALLY PUSHING FURTHER ESE INTO THE LOCAL
AREA AROUND THE WED-THU TIME FRAME, BUT THEN MAKES LITTLE EFFORT
TO PUSH OUT OF THE PLAINS THROUGH THE REST OF THE WEEK. THE
OVERALL BEST CHANCES FOR STORMS ARE TIED TO ITS INITIAL ARRIVAL
LATE TUE, MORE TUE NIGHT-WED NIGHT...WITH CHANCES MORE SCATTERED
AND HAVING LOWER OVERALL CONFIDENCE THURSDAY AND ON. POTENTIAL
FOR SOME STRONG-SEVERE STORMS REMAINS TUE-TUE NIGHT...WITH MOST
OF THE FORECAST AREA REMAINING IN THE SPC DAY 3 MARGINAL RISK
AREA.
AS FAR AS TEMPERATURES GO, PLENTY OF 80S LOOK TO LINGER ON INTO
TUESDAY...DROPPING BACK INTO THE 70S WED-SAT, TIED TO THOSE
ADDITIONAL PRECIP CHANCES IN THE FORECAST.
AVIATION /18Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 1219 PM CDT SUN SEP 14 2025
FOR KGRI/KEAR AIRPORTS:
A NARROWING SWATH OF SHOWERS WILL KEEP THE POTENTIAL FOR PRECIP
AROUND THE KGRI FOR A BIT AT THE START OF THIS TAF PERIOD, BUT
SHOULD CONTINUE TO DIMINISH/SHIFT NNE OVER THE NEXT HOUR OR TWO.
THE REST OF THIS AFTERNOON IS CURRENTLY DRY, WITH SHOWER/STORM
CHANCES RAMPING BACK UP LATE IN THE DAY/EVENING AS ACTIVITY
DEVELOPS/SLIDES IN FROM THE WEST. AT THIS POINT KEPT THE MENTION
AT/AFTER 00Z...BUT WILL HAVE TO WATCH HOW THINGS EVOLVE IN THAT
21-00Z TIMEFRAME. MAIN CHANCES LOOK TO BE BETWEEN 00-05Z...WITH
THE REST OF THIS PERIOD LOOKING DRY. AS THE PRECIP AND THICKER
MID- UPPER LEVEL CLOUD COVER DEPARTS, SEEING LOWER LEVEL CU
DEVELOPING IN ITS WAKE...AND THAT WILL BE POSSIBLE FOR THE
TERMINAL SITES, AND CEILINGS COULD BE MVFR, SO DO HAVE A TEMPO
GROUP IN FOR MID-LATE AFTERNOON. HAVE VFR CONDITIONS THIS
EVENING ON THROUGH THE REMAINDER OF THIS PERIOD. EXPECTING
GUSTY, GENERALLY SOUTHERLY WINDS THIS AFTERNOON AHEAD OF THE
MAIN SFC BOUNDARY OFF TO THE WEST, GUSTS NEAR 25 MPH ARE
FORECAST. THIS EVENING/TONIGHT, HAVE MAINLY LIGHT/VARIABLE WINDS
FOR BOTH SITES...TURNING BACK TO THE SOUTH AFTER SUNRISE MONDAY.
