...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF
NEBRASKA AND INTO NORTHERN KANSAS...
..SUMMARY
SCATTERED DAMAGING HAIL (SOME GREATER THAN 2 INCH DIAMETER) AND
SEVERE WIND GUSTS MAY OCCUR OVER PARTS OF THE CENTRAL PLAINS LATE
FRIDAY AFTERNOON AND EVENING. SCATTERED STORMS, SOME WITH SEVERE
WIND GUSTS, ARE POSSIBLE FRIDAY AFTERNOON OVER PARTS OF THE
CAROLINAS AND GEORGIA.
..NE INTO NORTHERN KS
MODERATE NORTHWEST FLOW ALOFT WILL DEVELOP OVER THE NORTHERN TO
CENTRAL PLAINS ON FRIDAY, AS A SURFACE TROUGH DEVELOPS OVER THE HIGH
PLAINS. THIS WILL RESULT IN DIRECTIONAL SHEAR WITH ELONGATED
HODOGRAPHS FEATURING 50 KT EFFECTIVE DEEP-LAYER SHEAR. STORMS ARE
EXPECTED TO DEVELOP NEAR THE LOW-LEVEL LAPSE RATE PLUME DURING THE
LATE AFTERNOON OVER CENTRAL TO WESTERN NE, WITH CELLS MOVING
SOUTHEASTWARD INTO THE MID 60S F DEWPOINTS AND PRODUCING VERY LARGE
HAIL. ISOLATED SIGNIFICANT WIND GUSTS MAY ALSO OCCUR IF
STORMS/OUTFLOWS MERGE, POSSIBLY EXTENDING INTO NORTHERN KS DURING
THE EVENING. OVERALL STORM COVERAGE IS UNCERTAIN, BUT AT LEAST
SCATTERED CELLS APPEAR LIKELY, WITH HIGH CONDITIONAL RISK OF SEVERE
HAIL/WIND.
..CAROLINAS...GA
A VERY MOIST AND UNSTABLE AIR MASS IS FORECAST OVER THE REGION ON
FRIDAY, NEAR A SURFACE TROUGH AND SOUTH OF A COLD FRONT PUSHING INTO
NC. NUMEROUS STORMS ARE FORECAST TO DEVELOP AFTER 20Z, WITHIN A WEAK
SHEAR/STRONG INSTABILITY ENVIRONMENT. MLCAPE IS FORECAST TO BE OVER
3000 J/KG, SUPPORTING VIGOROUS UPDRAFTS AND LOCALLY SEVERE
MICROBURSTS AND OUTFLOWS.
