...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF
THE LOWER TO MID MISSOURI VALLEY INTO THE CENTRAL AND SOUTHERN
PLAINS...
..SUMMARY
AN ISOLATED THREAT FOR LARGE HAIL AND STRONG WIND GUSTS IS EXPECTED
TO DEVELOP THURSDAY AFTERNOON AND EVENING IN PARTS OF THE LOWER TO
MID MISSOURI VALLEY WESTWARD INTO KANSAS, AND SOUTHWESTWARD INTO THE
TEXAS PANHANDLE.
..LOWER TO MID MISSOURI VALLEY/CENTRAL AND SOUTHERN PLAINS
A MID-LEVEL SHORTWAVE TROUGH WILL MOVE ACROSS THE NORTH-CENTRAL U.S.
ON THURSDAY, AS WESTERLY FLOW REMAINS OVER THE CENTRAL STATES. AT
THE SURFACE, MOISTURE RETURN WILL TAKE PLACE ACROSS THE SOUTHERN AND
CENTRAL PLAINS. A COLD FRONT IS FORECAST TO MOVE SOUTHWARD INTO FAR
NORTHERN KANSAS BY AFTERNOON. SURFACE HEATING AND INCREASING
LOW-LEVEL CONVERGENCE ALONG THE FRONT WILL RESULT IN SCATTERED
THUNDERSTORM DEVELOPMENT DURING THE LATE AFTERNOON, WITH STORMS
GRADUALLY INCREASING IN COVERAGE IN THE EVENING. THE LATEST MODEL
FORECASTS SUGGEST THAT A POCKET OF MODERATE INSTABILITY WILL DEVELOP
ACROSS NORTH-CENTRAL KANSAS, WITH WEAKER INSTABILITY EXTENDING
EASTWARD INTO NORTHERN MISSOURI. NAM FORECAST SOUNDINGS IN THE LATE
AFTERNOON NEAR THE FRONT SHOW ABOUT 40 KNOTS OF 0-6 KM SHEAR WITH
700-500 MB LAPSE RATES APPROACHING 8 C/KM. THIS SHOULD SUPPORT
ISOLATED SUPERCELL DEVELOPMENT WITH POTENTIAL FOR LARGE HAIL.
SURFACE TEMPERATURE-DEWPOINT SPREADS ARE FORECAST TO EXCEED 20 F
ALONG MUCH OF THIS CORRIDOR, WHICH WOULD CONTRIBUTE TO A POTENTIAL
FOR ISOLATED SEVERE GUSTS.
FURTHER SOUTHWEST INTO SOUTHWEST KANSAS AND THE TEXAS PANHANDLE,
DRYLINE DEVELOPMENT WILL BE POSSIBLE AS SURFACE DEWPOINTS GRADUALLY
INCREASE DURING THE DAY. ISOLATED THUNDERSTORMS MAY FORM TO THE EAST
OF THE DRYLINE DURING THE EARLY EVENING. WEAK INSTABILITY, MODERATE
DEEP-LAYER SHEAR AND STEEP MID-LEVEL LAPSE RATES MAY SUPPORT A
MARGINAL SEVERE THREAT. ISOLATED DAMAGING WIND GUSTS AND HAIL WILL
BE THE PRIMARY THREATS.
