DISCUSSION

A DECAYING MCS STRUGGLED TO MOVE EASTWARD OUT OF CENTRAL NEBRASKA
THIS MORNING. A FEW RAINDROPS MADE IT TO THE SURFACE, HOWEVER MOST
OF THE FORECAST AREA REMAINED DRY. BY NOON, TEMPERATURES HAD
REACHED THE MID 70S UNDER CLOUDY SKIES. HIGHS THIS AFTERNOON ARE
EXPECTED TO TOP OUT NEAR CLIMATE NORMALS, IN THE LOW TO MID 80S.
A WEAK COLD FRONT DRAPED FROM SOUTH-CENTRAL NEBRASKA THROUGH
NORTHWEST IOWA COULD BECOME THE FOCUS POINT FOR REDEVELOPMENT OF
CONVECTION, AS A SHORTWAVE MOVES ACROSS THE CENTRAL PLAINS THIS
AFTERNOON. CURRENT TRENDS IN THE MAJORITY OF THE CAMS KEEP STORM
DEVELOPMENT WELL TO OUR WEST, OVER WESTERN NEBRASKA. HOWEVER, A FEW
STILL WANT TO INITIATE STORMS ALONG THE BOUNDARY NEAR NORTHEAST
NEBRASKA LATE THIS AFTERNOON, AND BRING THEM SOUTHEAST ACROSS
EASTERN NEBRASKA THIS EVENING. WHILE THE FIRST SCENARIO APPEARS MORE
LIKELY, ANY STORMS THAT DO MANAGE TO DEVELOP IN OUR AREA WOULD BE
FUELED BY 1000-2500 J/KG OF INSTABILITY WITH 30-40KTS OF SHEAR
SUSTAINING UPDRAFTS, MAKING THEM CAPABLE OF PRODUCING LARGE HAIL AND
DAMAGING WINDS.
LOW PRESSURE WILL SETTLE SOUTHEAST INTO THE GREAT LAKES, DRAWING THE
COLD FRONT ACROSS THE REGION AND BRINGING TEMPERATURES DOWN INTO THE
LOW 80S FOR WEDNESDAY AND THURSDAY. THE COOLER TEMPERATURES WILL BE
ACCOMPANIED BY PLEASANT, DRY WEATHER AS SURFACE HIGH PRESSURE
SETTLES IN TO THE PLAINS.
WARMER TEMPERATURES RETURN AS AN UPPER RIDGE DRIFTS INTO THE CENTRAL
CONUS, FRIDAY. HIGHS WILL RETURN TO THE UPPER 80S AND LOW 90S BY THE
WEEKEND AND REMAIN THERE THROUGH EARLY NEXT WEEK. A HANDFUL OF RIDGE-
RIDING SHORTWAVES WILL BRING PERIODIC CHANCES FOR SHOWERS AND
STORMS.
AVIATION /00Z TAFS THROUGH 00Z THURSDAY/
ISSUED AT 614 PM CDT TUE AUG 25 2026
VFR CONDITIONS ARE EXPECTED TO PERSIST THROUGH THE NEXT 24
HOURS, AS NORTHWESTERLY WINDS HAVE SUNK SOUTHWARD. SPEEDS ARE
TRENDING DOWNWARD, WITH LARGELY NORTHWESTERLY WINDS (COULD BE
VARIABLE AT TIMES) AT LESS THAN 5 KTS SETTLE IN. LINGERING HUMID
AREAS COULD TURN FOGGY EARLY WEDNESDAY, SOUTHEAST OF KOMA/KLNK
AND CLOSER THE TO THE NE/MO/IA MUTUAL BORDERS. OTHERWISE
CLEARING SKIES TOMORROW WITH WINDS PICKING UP A BIT OUT OF THE
NORTHWEST WITH GUSTS OF 20 KTS NEAR KOFK AFTER 16Z.
