PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0511 AM CDT TUE OCT 26 2010

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE OHIO AND
TENNESSEE VALLEYS AND GREAT LAKES...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF WIDESPREAD DAMAGING WINDS AND A FEW TORNADOES OVER
PARTS OF THE OHIO AND TENNESSEE VALLEYS AND GREAT LAKES TODAY
THROUGH EARLY WEDNESDAY

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

EASTERN ILLINOIS
INDIANA
NORTHERN KENTUCKY
SOUTHERN MICHIGAN
WESTERN AND CENTRAL OHIO

ELSEWHERE...SEVERE STORMS ALSO ARE POSSIBLE FROM THE LOWER
MISSISSIPPI VALLEY NORTHEASTWARD INTO THE APPALACHIANS AND LOWER
GREAT LAKES

A POWERFUL JET STREAM DISTURBANCE...WITH WINDS IN EXCESS OF 175
MILES PER HOUR...WILL MOVE FROM THE CENTRAL ROCKIES ACROSS THE
CENTRAL PLAINS INTO OHIO VALLEY LATER TODAY AND TONIGHT.

AT THE SAME TIME...AN INTENSE SURFACE LOW ASSOCIATED WITH THE JET
WILL FURTHER STRENGTHEN AS IT TRACKS SLOWLY NORTHEAST FROM MINNESOTA
INTO WESTERN ONTARIO.

A COLD FRONT TRAILING SOUTH FROM THE LOW WILL SERVE AS THE MAIN
FOCUS FOR THUNDERSTORM DEVELOPMENT THROUGH EARLY WEDNESDAY AS THE
FRONT ACCELERATES EAST ACROSS THE OHIO AND TENNESSEE VALLEYS
TODAY...AND ACROSS THE LOWER GREAT LAKES AND THE APPALACHIANS
TONIGHT/EARLY WEDNESDAY.

THE VERY STRONG WINDS ASSOCIATED WITH THE LOW...AND INCREASING
MOISTURE SPREADING RAPIDLY NORTH FROM THE GULF COAST STATES...WILL
ALLOW THE THUNDERSTORMS TO ORGANIZE INTO BANDS THAT WILL BE CAPABLE
OF PRODUCING SWATHS OF DAMAGING WIND AND A FEW STRONG TORNADOES.

WHILE THE GREATEST RISK OF SEVERE WEATHER IS EXPECTED TO OCCUR
DURING THE DAY TODAY OVER THE OH AND TENNESSEE VALLEYS...A MORE
LIMITED THREAT FOR HIGH WIND AND ISOLATED TORNADOES WILL CONTINUE
THROUGH EARLY WEDNESDAY EASTWARD INTO THE APPALACHIANS AND THE LOWER
GREAT LAKES.

STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY
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.
