KEY MESSAGES
- PRIMARY SEVERE THREAT FOR THE ENTIRE CWA WILL OCCUR AFTER 9PM.
A LINE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO MOVE
THROUGH, WITH WIND GUSTS BEING THE PRIMARY HAZARD.
- DISCRETE THUNDERSTORMS MAY DEVELOP IN NORTHEASTERN
KANSAS/NORTHWESTERN MISSOURI AHEAD OF THE COLD FRONT EARLY
THIS EVENING. THESE CELLS WOULD BE CAPABLE OF ALL SEVERE
HAZARDS.
- STORMS MOVING NORTHWARD FROM OKLAHOMA MAY IMPACT SOUTHERN
PORTIONS OF THE CWA, BUT THE THREAT IS MORE CONDITIONAL.
- NEXT CHANCE OF STRONG TO SEVERE STORMS WILL BE ON TUESDAY.

AS OF EARLY FRIDAY AFTERNOON, A BAND OF WEAKENING SHOWERS AND
THUNDERSTORMS CONTINUES TO IMPACT THE SOUTH AND EASTERN PORTIONS OF
THE CWA WITH STRATUS BUILDING INTO THE AREA FROM THE WEST. AN AREA
OF SURFACE LOW PRESSURE CURRENTLY SITS TO OUR NORTH, LINKED TO
ANOTHER SURFACE LOW OVER CENTRAL KANSAS BY A COLD FRONT. IN THE
COMING HOURS, A MID-LEVEL IMPULSE WILL BE EJECTED EASTWARD OUT AHEAD
OF THE LARGER MID/UPPER-LEVEL TROUGH. GENERALLY SPEAKING, A NARROW
BAND OF COUNTIES IN NORTHWEST MISSOURI AND SPOTS ALONG THE EASTERN
CWA BORDER HAVE BEEN THE ONLY AREAS TO SEE MUCH CLEARING OR PEAKS OF
SUNSHINE TODAY. UNSURPRISINGLY, AREAS THAT HAVE BEEN LARGELY
ENVELOPED BY CLOUDS AND PRECIPITATION THIS MORNING HAVE STRUGGLED TO
BREAK INTO THE 70S, WITH MANY LOCATIONS CENTRAL TO THE KC METRO
HOVERING AROUND THE LOW TO MID 60S SINCE DAYBREAK THIS MORNING.
IN SOME WAYS, HOW THE EARLIER PART OF THE DAY HAS TRANSPIRED HAS
ALLEVIATED SOME UNCERTAINTY AS WE HEAD INTO THE LATE AFTERNOON AND
EARLY EVENING. HOWEVER, UNCERTAINTY HAS NOT BEEN ELIMINATED, AND
RECENT MODEL GUIDANCE AND SOUNDING DATA HAS LED TO FURTHER
QUESTIONING ABOUT THIS EVENING'S ORDER OF EVENTS. THE GREATEST AND
MOST WIDESPREAD SEVERE THREATS ARE ASSOCIATED WITH A QLCS THAT MOVES
THROUGH AHEAD OF A COLD FRONTAL PASSAGE LATE THIS TONIGHT. WHAT
HAPPENS BETWEEN NOW AND THE COLD FRONTAL PASSAGE IS TRICKY, BUT
CURRENT THINKING IS THAT BETWEEN NOW AND ROUGHLY 00Z, SHOWERS/STORMS
WILL BE MOSTLY POP-UP-ESQUE, WITH AN EXCEPTION FOR NORTHEASTERN
KANSAS AND NORTHWESTERN MISSOURI. ASSUMING THERE ARE NO OR VERY
LIMITED CHANGES TO THE ENVIRONMENT, IT IS UNLIKELY THAT WE WILL SEE
ORGANIZED, DISCRETE CONVECTION INITIATING IN THE MAJORITY WARM
SECTOR. THE CAP APPEARS TO HAVE MOSTLY ERODED BY EVAPORATIVE
COOLING, AND LOW/MID-LEVEL LAPSE RATES FOR CENTRAL AND SOUTHERN
PORTIONS OF THE CWA DON'T DO MUCH TO IMPRESS CURRENTLY. THE DAYTIME
PRECIPITATION AND CLOUD COVER HAS LARGELY INHIBITED OUR ABILITY TO
DESTABILIZE VIA INSOLATION SO FAR, THOUGH THE OBSERVED BREAKS IN
CLOUD COVER IN NE KANSAS AND NW MISSOURI MAY ALLOW FOR SOME MORE
ORGANIZED DISCRETE CONVECTION AHEAD OF THE COLD FRONT. HOWEVER, EVEN
IF DISCRETE CELLS FORM IN THESE AREAS, IT IS UNCLEAR WHETHER THEY
WILL BE ABLE TO REALIZE THEIR "FULL" SEVERE POTENTIAL BEFORE GETTING
UNDERCUT BY THE COLD FRONT. HOWEVER, SHOULD DISCRETE STORMS DEVELOP
HERE, THIS WOULD BE THE AREA WITH THE GREATEST TORNADO AND HAIL
THREAT.
AT THE TIME OF WRITING, CONVECTION IS INITIATING IN PORTIONS OF WFO
TULSA'S AREA. RECENT CAM GUIDANCE HAS PICKED UP ON THIS DEVELOPMENT
AND HAS BEEN MOVING IT NORTHWARD THROUGH THE EVENING WITH A
RESURGENCE OF MOISTURE AND INSTABILITY INTO OUR AREA AS DEEP LAYER
MOISTURE FLUX CONVERGENCE INCREASES TO OUR SOUTH AND WEST. SHOULD
THE LOCAL ENVIRONMENT IMPROVE, THESE STORMS COULD CREATE PROBLEMS
FOR THE SOUTHERN PORTION OF OUR CWA, PRIMARILY AFTER 00Z. OUR SHEAR
PROFILE IS MORE THAN ADEQUATE TO SUPPORT SEVERE CONVECTION (0-6KM
BULK SHEAR >40KT IN LATEST MESOANALYSIS), SO IF WE ARE ABLE TO
SUCCESSFULLY REBOUND FROM AM/EARLY PM CONVECTION AND DESTABILIZE VIA
WAA, WE COULD SEE A GREATER SEVERE THREAT WITH THESE STORMS. WE ARE
ALSO BEGINNING TO NOTE SOME CLEARING JUST WEST OF THE MO/KS STATE
LINE WHICH COULD ALSO SUPPORT DESTABILIZATION. WE COULD SEE ALL
HAZARD TYPES WITH THESE STORMS, BUT THERE IS MORE UNCERTAINTY
REGARDING HOW THE ENVIRONMENT WILL EVOLVE AHEAD OF THEM, THUS
LEADING TO QUESTIONS REGARDING STORM BEHAVIOR.
CONFIDENCE REGARDING TONIGHT'S QLCS EVENT REMAINS MUCH HIGHER,
REGARDLESS OF WHAT OCCURS AHEAD OF THE COLD FRONT. WE EXPECT ANY
INITIAL DEVELOPMENT IN NE KANSAS AND NW MISSOURI TO GROW UPSCALE BY
02Z-03Z, THEN MOVING THROUGH THE ENTIRE CWA BEFORE EXITING BY 10Z.
DEEP LAYER SHEAR CONTINUES TO BE GREATEST ALONG THE LEADING EDGE OF
THE FRONT WITH MODERATE INSTABILITY. MORE RECENT MODEL RUNS SUGGEST
THAT THE 0-3KM SHEAR VECTOR ALIGNS SLIGHTLY MORE PERPENDICULAR TO
THE LINE WHICH MAY INCREASE POTENTIAL FOR EMBEDDED MESOVORTICES
ALONG THE LINE. STILL, THE MAIN THREAT WOULD BE SEVERE WIND GUSTS AS
THE LINE MOVES THROUGH. DESPITE TRAINING PRECIPITATION THIS MORNING,
THE PROGRESSIVE NATURE OF THE LINE TONIGHT SHOULD LIMIT HYDROLOGICAL
IMPACTS.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
ISSUED AT 602 PM CST FRI MAR 6 2026
CONVECTION IS CURRENTLY ONGOING EAST OF THE KC METRO TOWARD
CENTRAL MISSOURI AND NORTHWEST OF THE TERMINALS CLOSER TO THE
COLD FRONT, BUT ALL TERMINALS REMAIN PRECIPITATION FREE AT THIS
TIME. A LINE OF SHOWERS AND THUNDERSTORMS IS LIKELY TO IMPACT
STJ BETWEEN 330Z AND 530Z AND THE KC METRO TERMINALS BETWEEN
430Z AND 07Z, WITH GUSTY WNW WINDS AND HEAVY RAIN LEADING TO
REDUCED VIS ALONG THE LEADING EDGE OF THE LINE. OTHERWISE, CIGS
AT THE MOMENT ARE BETWEEN 2500 AND 3500 FEET, WITH ALL TERMINALS
LIKELY TO BECOME SOLIDLY MVFR (CIGS AROUND 1500 FT) BY AROUND 7Z
TONIGHT, WITH CONDITIONS IMPROVING TO VFR BY AROUND 16Z
SATURDAY MORNING. BREEZY SOUTHERLY WINDS WILL TURN NORTHWESTERLY
BEHIND THE FRONT, WITH SUSTAINED WINDS AROUND 10 TO 12 KNOTS AND
GUSTS UP TO 20 KNOTS.
