DISCUSSION
ISSUED AT 127 PM CDT SAT APR 19 2025
TONIGHT--SUNDAY...EXPECTING SHOWERS WITH EMBEDDED THUNDERSTORMS TO
GRADUALLY EXPAND IN COVERAGE FROM THE SOUTHWEST TONIGHT THROUGH
SUNDAY, AS A DEEP/POWERFUL UPPER TROUGH APPROACHES FROM THE
SOUTHWEST AND EVENTUALLY EJECTS NORTHEAST ACROSS THE
CENTRAL/SOUTHERN PLAINS. GIVEN THE STRONG FORCING AMIDST MARGINAL
INSTABILITY AND SEASONABLY HIGH PRECIPITABLE WATERS, POCKETS OF
HEAVY RAINFALL ARE LIKELY, WHICH MAY PRODUCE SOME LOCALIZED MINOR
FLOODING, ESPECIALLY OVER SOUTHEAST KANSAS. WIDESPREAD MEANINGFUL
RAINFALL IS LIKELY AREAWIDE (THIS IS IN ADDITION TO WHAT'S ALREADY
OCCURRED). HREF PROBABILITIES SUPPORT CENTRAL KANSAS LIKELY SEEING
AN ADDITIONAL 0.50-1.00+ INCHES, WITH LOCATIONS FURTHER SOUTHEAST
SEEING AN ADDITIONAL 0.75-2.00+ INCHES, HIGHEST OVER EXTREME
SOUTHEAST KANSAS. RAIN SHOULD EXIT TO THE NORTHEAST BY MID-LATE
AFTERNOON SUNDAY.
IN ADDITION TO THE RAIN, THE STRONG FORCING COUPLED WITH MARGINAL
INSTABILITY AND STRONG VERTICAL SHEAR MAY SUPPORT A FEW STRONG TO
MARGINALLY SEVERE THUNDERSTORMS, ESPECIALLY FROM ROUGHLY THE FLINT
HILLS ON EAST SUNDAY MORNING THROUGH ABOUT MID AFTERNOON. THINKING
THE MAIN THREATS WILL BE SMALL HAIL, 50-60 MPH WINDS, AND PERHAPS A
BRIEF TORNADO GIVEN THE POTENTIAL FOR STRONG LOW-LEVEL SHEAR. THE
GREATEST POTENTIAL FOR MORE NUMEROUS ORGANIZED SEVERE WEATHER WILL BE
JUST EAST OF THE FORECAST AREA ACROSS MISSOURI.
LATE TUESDAY--THURSDAY NIGHT...DETERMINISTIC AND ENSEMBLE CONSENSUS
CONTINUES TO SUPPORT AN ACTIVE PERIOD THUNDERSTORM-WISE, AS A PAIR
OF COLD FRONTAL ZONES OOZE SOUTH THROUGH THE REGION TUESDAY EVENING-
NIGHT, AND AGAIN SOMETIME WEDNESDAY EVENING THROUGH THURSDAY NIGHT.
PER MODEL CLIMATOLOGIES, FORECAST MOISTURE AND INSTABILITY LOOK TO
BE SEASONABLY HIGH, ALTHOUGH EFFECTIVE DEEP LAYER SHEAR APPEARS TO
BE ONLY SO-SO. THEREFORE, LOCALIZED SEVERE THUNDERSTORMS ALONG WITH
LOCALLY HEAVY RAINFALL APPEAR POSSIBLE, BUT ORGANIZED WIDESPREAD
SEVERE WEATHER LOOKS UNLIKELY AT THIS TIME.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 1240 AM CDT SUN APR 20 2025

OF CENTRAL AND SOUTH CENTRAL KANSAS AROUND DAYBREAK. IFR
CEILINGS ARE ALSO EXPANDING NORTHWARD OUT OF OKLAHOMA EARLY THIS

AS LOW AS LIFR CONDITIONS FOR MOST OF THE MORNING HOURS. AS A
WARM FRONT LIFTS NORTH THIS MORNING CNU, MAY SEE A RETURN OF
SOUTHERLY WINDS THIS MORNING BEFORE EVENTUALLY SWITCHING TO THE
WEST THIS AFTERNOON AS A COLD FRONT SWINGS THROUGH. THIS FRONT
WILL SHIFT PRECIPITATION AND LOWER CEILINGS OFF TO THE EAST
