...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON
AND EVENING OVER PARTS OF SOUTHERN IOWA...NORTHERN MISSOURI...AND
WESTERN ILLINOIS....
..SUMMARY
THUNDERSTORMS ARE EXPECTED TO EVOLVE INTO AN EXTENSIVE LINE THIS
EVENING FROM IOWA TO OKLAHOMA AND NORTHWEST TEXAS, WITH THE PRIMARY
THREATS OF LARGE HAIL AND DAMAGING WINDS. A FEW TORNADOES ARE ALSO
POSSIBLE IN ANY SUPERCELLS THAT CAN FORM AHEAD OF THE LINE OVER
PARTS OF IOWA, MISSOURI, AND CENTRAL ILLINOIS.
..MO/IA/IL
LATEST SURFACE ANALYSIS SHOWS A LOW OVER NORTHEAST KS. THIS LOW
WILL TRACK NORTHEASTWARD ACROSS SOUTHERN IA TODAY, WITH THE
ASSOCIATED WARM FRONT LIFTING NORTHWARD INTO NORTHERN IL. THE AIR
MASS IN THE WARM SECTOR OF THE LOW WILL BE RELATIVELY MOIST AND
UNSTABLE WITH DEWPOINTS IN THE LOWER 60S AND AFTERNOON MLCAPE VALUES
OF 2000 J/KG. THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR THE
SURFACE LOW IN IA, AND MORE WIDELY SCATTERED STORMS EASTWARD ALONG
THE WARM FRONT. A FEW SUPERCELLS ARE POSSIBLE ACROSS THIS REGION,
WITH A CONCERN FOR TORNADOES, LARGE HAIL, AND DAMAGING WINDS IN THE
MOST INTENSE CELLS.
..MO/KS/OK/TX
AN EXTENSIVE LINE OF THUNDERSTORMS IS EXPECTED TO FORM ALONG THE
COLD FRONT THIS AFTERNOON FROM WESTERN MO INTO SOUTHEAST KS AND MUCH
OF OK. AMPLE LOW-LEVEL MOISTURE AND CAPE WILL BE PRESENT AHEAD OF
THE STORMS, ALONG WITH SUFFICIENT DEEP-LAYER SHEAR FOR
ROTATING/BOWING STORM STRUCTURES. LARGE HAIL AND DAMAGING WINDS
APPEAR TO BE THE MAIN CONCERN, BUT A TORNADO OR TWO ARE ALSO
POSSIBLE.
