MOSAIC REFLECTIVITY EARLY THURS AM DEPICTED A BROKEN LINE OF STORMS
MOVING ESEWRD ACRS SRN MO. OBJECTIVE SFC ANALYSIS INDICATED A CDFRNT
ORIENTED SWWRD FM A GREAT LAKES SFC LOW, SLOWLY APPROACHING THE
OZARK PLATEAU. THRU THE DAY TODAY, THIS FRNT WL SLOWLY MOVE SWRD
INTO THE FA, W/ NRLY WINDS USHERING IN DRIER AIR.
AFTN SBCAPE VALUES OF 2000-3000 J/KG AND NWRLY EFFECTIVE SHEAR OF 20
TO 30 KTS WL SUPPORT SOME ORGANIZED STORM POTENTIAL ACRS THE NRN
HALF OF AR THURS AFTN TO EVNG. PT FCST SOUNDINGS INDICATE SOME DRIER
AIR ALOFT, W/ MODEST LOW-LEVEL THETA-E DIFFERENCES, AND 3CAPE VALUES
NEAR 80-100 J/KG, ALLUDING TO MAINLY A DAMAGING WIND THREAT W/ ANY
PULSING CONVECTIVE ACTIVITY.
INTO FRI, THE AFOREMENTIONED FRNT IS PROGGED TO CONTINUE SLOWLY
MOVING SWRD, STALLING OVER SRN AR BY FRI EVNG, CONTINUING TO SERVE
AS THE FOCUS FOR POPS, AND AN ATTENDANT, BUT LOW SEVERE THREAT THRU
THE DAY. BEHIND THE FRNT, COOLER AND LESS HUMID CONDNS WL BE SEEN BY
THE NRN TWO-THIRDS OF THE STATE.
THRU THE WEEKEND, MEAN H500 NWRLY FLOW WL PERSIST ACRS THE MIDWEST
REGION, W/ BROAD SFC HIGH PRESSURE LINGERING OVER THE MID-SOUTH
VCTY. A WRLY COMPONENT TO H500 FLOW WL PROMOTE LEE SFC CYCLONIC FLOW
ACRS THE SRN PLAINS, W/ SRLY SFC FLOW QUICKLY RESUMING OVER THE
STATE BY SAT. AS SFC CYCLONIC FLOW BECOMES MORE ORGANIZED AND
MANEUVERS EWRD, A BROAD WARM SECTOR IS PROGGED TO EXTEND OVER MUCH
OF THE SRN PLAINS AND INTO THE OZARK PLATEAU. THERE IS STILL A
MODERATE DEGREE OF UNCERTAINTY THRU THIS PD, THOUGH DETERMINISTIC
GUIDANCE CONTINUES TO SUGGEST A FEW SHORTWAVE TROUGHS MANEUVERING
THRU MEAN NWRLY FLOW, W/ MASS FIELDS INDICATING STRONG COLD POOL/MCS
ACTIVITY FOLLOWING THE PERIPHERY OF THE AFOREMENTIONED WRM FRNT INTO
NRN AR SAT AND SUN NIGHTS. MON AND THRU MID-WEEK, H500 NWRLY FLOW WL
CONTINUE, W/ DAILY SCATTERED POP AND THUNDERSTORM COVG FAVORED ACRS
THE FA.
IN ADDITION TO SEVERE THREATS THRU THE WEEKEND, HIGHER QPF VALUES
REMAIN POSSIBLE THRU THE LATTER HALF OF THE PD, W/ NBM/WPC GUIDANCE
CONTINUING TO ADVERTISE A CORRIDOR OF TWO TO FOUR INCHES OF
RAINFALL ACRS THE WRN HALF OF THE FA. TEMPS THRU THE PD WL STAY NEAR
NORMAL VALUES, W/ INTERMITTENT BOUTS OF COOLER THAN NORMAL TEMPS
BEHIND PASSING CDFRNTS, AND LIMITED CONCERNS FOR HAZARDOUS HEAT
CONDNS.

ISSUED AT 1232 AM CDT FRI JUN 19 2026
VFR CONDNS WERE NOTED OVER MUCH OF THE FA W/ SOME HIGH CLOUD COVG
LINGERING OVER CNTRL AR FM EARLIER THURS NIGHT CONVECTION. THRU
THE PD, A STALLED FRNT OVER CNTRL AR WL CONTINUE TO SLOWLY MOVE
SWRD, AND SERVE AS A FOCUS FOR ADDITIONAL PRECIP DEVELOPMENT THRU
THE DAY FRI, MAINLY IMPACTING CNTRL TO SRN TERMINALS. ADDITIONAL
STORMS MAY MOVE INTO SWRN AR LATER THURS AFTN, AND MOVE EWRD
QUICKLY ALONG THE AFOREMENTIONED FRNT, BUT CONFIDENCE REMAINS LOW
AT THE MOMENT. OTHERWISE, MVFR CIGS WL SETTLE OVER PORTIONS OF
SWRN TO CNTRL AR BY 12Z FRI MRNG, AND LATER IMPROVE TO VFR LEVELS
BY 18Z AT MOST LOCATIONS. WINDS WL STAY NERLY THRU THE DAY BEHIND
THE FRNT.
