NATIONAL WEATHER SERVICE DES MOINES IA
754 AM CDT THURSDAY JULY 02 1992

THE NATIONAL SEVERE STORMS FORECAST CENTER IN KANSAS CITY MISSOURI
IS FORECASTING AN OUTBREAK OF SEVERE THUNDERSTORMS AND TORNADOES
TODAY INTO TONIGHT OVER PORTIONS OF THE UPPER AND MIDDLE MISSISSIPPI
VALLEY AND EXTREME EASTERN CENTRAL PLAINS.

THE STATES WHICH ARE MOST LIKELY TO EXPERIENCE THE BRUNT OF THE
SEVERE THUNDERSTORM ACTIVITY INCLUDE...EXTREME EASTERN NEBRASKA
...NORTHEASTERN KANSAS...SOUTHERN MINNESOTA...SOUTHWESTERN
WISCONSIN...ALL OF IOWA...MUCH OF WESTERN ILLINOIS...AND THE NORTHERN
HALF OF MISSOURI.

A SURFACE LOW PRESSURE AREA OVER SOUTH CENTRAL KANSAS IS FORECAST TO
INTENSIFY AS IT MOVES NORTHEASTWARD TOWARD NORTHERN IOWA LATE THIS
AFTERNOON AND TONIGHT. ASSOCIATED COLD FRONTAL SYSTEM IS FORECAST TO
PUNCH INTO CENTRAL PLAINS AND ACT AS PRIMARY FOCUS FOR THE DEVELOPMENT
OF WIDESPREAD SEVERE THUNDERSTORMS FROM EASTERN KANSAS INTO UPPER
MISSISSIPPI VALLEY. AIR MASS AHEAD OF FRONTAL SYSTEM WILL BE VERY WARM
...MOIST AND UNSTABLE. VERY STRONG AND GUSTY SOUTHERLY WINDS AHEAD OF
THE COLD FRONT WILL CONTINUE TO PULL MOIST UNSTABLE AIR NORTHWARD INTO
THE THREAT REGION. THE INTENSIFYING WEATHER SYSTEM IS A REFLECTION OF A
SIGNIFICANT MID LEVEL SHORTWAVE TROUGH FORECAST TO DEEPEN AS A MID
LEVEL WIND MAX PUNCHES INTO THE CENTRAL PLAINS.

THE COMBINATION OF AN INTENSIFYING LOW PRESSURE SYSTEM...STRONG MID
LEVEL WINDS AND A MOIST UNSTABLE AIR MASS AHEAD OF THE COLD FRONT IS
EXPECTED TO RESULT IN POTENTIALLY DESTRUCTIVE TORNADOES...AS WELL AS
DAMAGING STRAIGHT LINE WINDS AND LARGE HAIL. AGAIN...IT IS EMPHASIZED
THAT THIS IS A DANGEROUS WEATHER SITUATION FROM THE EASTERN CENTRAL
PLAINS TO THE UPPER AND MIDDLE MISSISSIPPI VALLEY.

ALL PERSONS IN THE THREATENED AREA ARE URGED TO REVIEW SAFETY RULES
...AND LISTEN TO RADIO..TV..OR NOAA WEATHER RADIO FOR LATER
