PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0938 AM CDT THU MAY 29 2008

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CENTRAL PLAINS
THIS AFTERNOON AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF A FEW STRONG TORNADOES OVER PARTS OF THE CENTRAL
PLAINS THIS AFTERNOON AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

WESTERN IOWA
EASTERN HALF OF NEBRASKA
FAR SOUTHEAST SOUTH DAKOTA

ELSEWHERE...ORGANIZED SEVERE STORMS ARE ALSO POSSIBLE SURROUNDING
THE HIGH RISK FROM WESTERN KANSAS TO SOUTHERN WI.

VERY WARM...MOIST AND BUOYANT AIRMASS IS SPREADING NORTHWARD ACROSS
THE PLAINS THIS MORNING. THIS NORTHWARD SURGE IN INSTABILITY WILL
CREATE A FAVORABLE ENVIRONMENT FOR ORGANIZED...POTENTIALLY
DAMAGING...SEVERE THUNDERSTORMS LATER THIS AFTERNOON/EVENING ACROSS
THE CENTRAL PLAINS INTO THE MID MS VALLEY REGION.

MID-HIGH LEVEL JET STREAM WINDS WILL INCREASE ACROSS THE CENTRAL
ROCKIES INTO THE CENTRAL PLAINS LATER THIS AFTERNOON...ENHANCING THE
VERTICAL SHEAR PROFILES FOR SUPERCELL THUNDERSTORMS. GIVEN THE
INCREASE IN MOISTURE...ATMOSPHERIC CONDITIONS APPEAR TO BE QUITE
FAVORABLE FOR TORNADO DEVELOPMENT LATER TODAY INTO THE EVENING HOURS
ACROSS PORTIONS OF NEBRASKA INTO WESTERN IOWA. IN ADDITION...VERY
LARGE HAIL AND DAMAGING WINDS COULD ALSO ACCOMPANY SEVERE
THUNDERSTORMS INTO THE OVERNIGHT HOURS AS ACTIVITY SPREADS TOWARD
SRN WI.

THIS IS POTENTIALLY A VERY DANGEROUS SITUATION. THOSE IN THE
THREATENED AREA ARE URGED TO REVIEW SEVERE WEATHER SAFETY RULES AND
TO LISTEN TO RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR
POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
