RAIN COVERAGE HAS BEEN ON THE DECREASE THIS AFTERNOON, WITH ONLY  
SPOTTY SHOWERS POSSIBLE THRU TONIGHT ACROSS FAR EASTERN OK INTO  
WESTERN AR.  
 
FOCUS OF THIS FORECAST CONTINUES TO BE IN THE SATURDAY NIGHT INTO  
SUNDAY TIME FRAME. A TRANSITION TO AN ACTIVE SWRLY FLOW PATTERN  
ALOFT WILL OCCUR, WITH THE INITIAL SHORTWAVE TROUGH AND MID-LEVEL  
JET PUNCHING INTO THE PLAINS THIS WEEKEND. AT THE SURFACE BY LATE  
SATURDAY, A COLD FRONT WILL BE ADVANCING SOUTHEAST ACROSS KS WITH  
A TRIPLE POINT/WEAK FRONTAL LOW SETTING UP OVER NW OK, WITH THE  
DRYLINE EXTENDING SOUTH OVER FAR WESTERN OK. WE'RE NOW INTO THE  
CAM TIME FRAME, AND THE 06Z AND 12Z RUNS OF THE HRRR AS WELL AS  
THE HREF SUGGEST THAT WE STAY DRY THRU 00Z WITH DEVELOPMENT FROM  
NEAR THE TRIPLE POINT ON UP THE FRONT INTO KS DURING THE EVENING.  
THE 06Z AND 12Z EC ARE SHOWING DEVELOPMENT A BIT FARTHER SOUTH  
ALONG THE DRYLINE, BUT THIS SOLUTION IS IN THE MINORITY WHEN  
COMPARED TO MOST CAMS AND OTHER GLOBAL MODELS. IF THE STORMS ON  
THE SOUTHERN END CAN REMAIN MORE CELLULAR, CYCLONICALLY CURVED  
HODOGRAPHS IN THE LOW LEVELS SUGGEST AN ENVIRONMENT FAVORABLE FOR  
HIGHER IMPACT SEVERE WEATHER INTO NE OK (MORE LIKELY CLOSER TO  
THE KS BORDER) SATURDAY NIGHT. THE 12Z HRRR SUGGESTED THAT STORMS  
MAY HAVE A TENDENCY TO BE MORE OUTFLOW DOMINANT, SUGGESTING THAT  
DAMAGING WIND WOULD BE MORE OF A THREAT THAN TORNADOES, BUT TRENDS  
WILL NEED TO BE MONITORED. EVENTUALLY THIS ACTIVITY WILL RUN OUT  
OF STEAM TOWARD DAYBREAK SUNDAY MORNING.  
 
THE GLOBAL MODELS ARE FASTER WITH THE FRONT COMPARED TO YESTERDAY,  
ESPECIALLY THE EC AND UKMET. BOTH OF THESE MODELS INITIATE STORMS  
IN THE SE OK/WEST-CENTRAL AR BORDER VICINITY SUNDAY AFTERNOON.  
INSTABILITY AND DEEP-LAYER SHEAR ARE FAVORABLE FOR SEVERE STORMS,  
BUT HODOGRAPHS ARE MORE STRAIGHT AND SHOW MUCH LESS LOW LEVEL  
SHEAR COMPARED TO SATURDAY NIGHT. THIS SUGGESTS THAT HAIL AND WIND  
WOULD BE PRIMARY THREATS WITH THE INITIAL STORMS BEFORE THEY  
SHIFT EAST OF THE AREA BY EVENING.

LONG TERM
 
 
(MONDAY THROUGH FRIDAY)  
ISSUED AT 214 PM CDT FRI MAR 28 2025  
 
THE WORK WEEK WILL START OFF COOLER THAN AVERAGE AND QUIET, BUT IN  
THE SPRING THINGS CHANGE QUICKLY. THE NEXT STRONG SHORTWAVE TROUGH  
WILL MOVE INTO THE PLAINS TOWARD MIDWEEK, WITH STRONG TO SEVERE  
STORM POTENTIAL STARTING TUESDAY NIGHT AND CONTINUING INTO  
WEDNESDAY. SOME SEVERE POTENTIAL MAY LINGER IN THE SOUTHEAST THRU  
THE END OF THE WEEK DEPENDING ON WHERE THE FRONTAL BOUNDARY LIES.  
THE 12Z EC KEEPS THE WARM SECTOR JUST OUT OF OUR AREA DURING THIS  
TIME, BUT OF COURSE THIS IS SUBJECT TO CHANGE. THE BOUNDARY COULD  
ALSO FOCUS A HEAVY RAIN AXIS THAT COULD BE NEAR OR JUST INTO OUR  
CWA AS MULTIPLE ROUNDS OF STORMS TRACK OVER THE SAME AREAS THRU  
THE END OF THE WEEK. AFTER A SYSTEM MOVES ACROSS NEXT WEEKEND, A  
BIG PATTERN CHANGE IS IN STORE THAT WOULD BRING COOLER AND MUCH  
QUIETER WEATHER TO THE REGION FOR AT LEAST A WEEK.

(00Z TAFS)  
ISSUED AT 646 PM CDT FRI MAR 28 2025  
 
SCATTERED TO BROKEN MID CLOUDS THIS EVENING ARE EXPECTED TO AGAIN  
BECOME BROKEN/OVERCAST MVFR CEILINGS LATE EVENING INTO THE  
OVERNIGHT HOURS TONIGHT AS THE BACKSIDE OF AN AREA OF LOW PRESSURE  
LIFTS NORTHEAST THROUGH THE REGION. A FEW ISOLATED SHOWERS REMAIN  
POSSIBLE ACROSS PARTS OF WESTERN ARKANSAS TONIGHT WITH THE EXITING  
LOW. HOWEVER, THE GREATER POTENTIAL LOOKS TO BE EAST OF KFSM AND  
WILL HOLD OFF ON ADDING ADDITIONAL MENTIONS OF PRECIP TONIGHT.  
LATE TONIGHT INTO SATURDAY MORNING THERE IS POTENTIAL FOR A PERIOD  
OF IFR CONDITIONS OVER THE CWA BEFORE CEILINGS BEGIN TO RISE BACK  
TO LOW END VFR LATE MORNING INTO THE AFTERNOON HOURS SATURDAY.  
SCATTERED TO BROKEN MID CLOUDS ARE FORECAST FOR THE CWA LATE IN  
THE TAF PERIOD. WINDS THROUGH THE PERIOD START OUT BREEZY FROM  
THE SOUTH AND WEAKEN SOME OVERNIGHT BEFORE INCREASING AGAIN OUT OF  
THE SOUTH DURING THE DAY SATURDAY. THE EXCEPTION WILL AGAIN BE  
KFSM WHERE A PERIOD OF EASTERLY WINDS ARE FORECAST LATE TONIGHT  
INTO SATURDAY MORNING.
