PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0402 AM CDT WED JUN 12 2013
...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE UPPER MIDWEST
INTO THE OHIO VALLEY THIS AFTERNOON AND TONIGHT...
THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF WIDESPREAD DAMAGING WINDS...LARGE HAIL AND A FEW
TORNADOES OVER PARTS OF THE UPPER MIDWEST INTO THE OHIO VALLEY THIS
AFTERNOON AND TONIGHT.
THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
EASTERN IOWA
NORTHERN AND CENTRAL ILLINOIS
MUCH OF INDIANA
WESTERN OHIO
ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE IN SURROUNDING
AREAS...INCLUDING PARTS OF THE MIDDLE MISSISSIPPI VALLEY...SOUTHERN
GREAT LAKES...CENTRAL APPALACHIANS AND MID ATLANTIC COAST
STATES...AS WELL AS ACROSS PARTS OF THE NORTHERN ROCKIES INTO
ADJACENT HIGH PLAINS.
THE ENVIRONMENT IS BECOMING VERY MOIST AND UNSTABLE ALONG A STALLED
FRONTAL ZONE EXTENDING FROM THE MID ATLANTIC COAST WEST
NORTHWESTWARD THROUGH THE OHIO VALLEY...TO A DEVELOPING AREA OF LOW
PRESSURE ACROSS THE MIDDLE MISSOURI VALLEY. THIS LOW IS EXPECTED TO
BECOME THE FOCUS FOR INTENSE THUNDERSTORM DEVELOPMENT AS IT TRACKS
EASTWARD ACROSS EASTERN IOWA INTO NORTHERN ILLINOIS THIS
AFTERNOON...WHERE CONDITIONS LIKELY WILL BECOME CONDUCIVE TO THE
EVOLUTION OF A LARGE AND ORGANIZED CLUSTER OF STORMS. THIS ACTIVITY
IS THEN EXPECTED TO SPREAD RAPIDLY EAST SOUTHEASTWARD ACROSS
SOUTHERN PORTIONS OF THE GREAT LAKES REGION...AND SOUTHWARD TOWARD
THE LOWER OHIO VALLEY....LATE THIS AFTERNOON AND EVENING.
WIDESPREAD STRONG...POTENTIALLY DAMAGING...WIND GUSTS ARE
POSSIBLE...ALONG WITH THE RISK FOR LARGE HAIL. A FEW TORNADOES ARE
ALSO POSSIBLE...PARTICULARLY WITH EARLY STORMS ACROSS PARTS OF
EASTERN IOWA INTO NORTHERN ILLINOIS.
STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
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.
