1129 AM EDT THU AUG 01 2002

FIRST LINE OF CONVECTION OVER WESTERN UPPER PENINSULA WEAKENED AS IT
APPROACHED EASTERN UPPER PENINSULA EARLIER THIS MORNING. THIS MOST
LIKELY DUE TO MODERATELY STRONG CAP IN PLACE. THIS CAP IS FORECAST
TO RAPIDLY WEAKEN THIS AFTERNOON AS STRONG TROUGH AND ASSOCIATED
COLD FRONT PROGRESS TO THE SOUTHEAST TOWARD THE CWA. IN ADDITION...
AREA GETS INTO COUPLED JET WITH LF QUAD OF 100 KNOT TO THE NORTHWEST
AND RR QUAD OF 95 KNOT JET TO THE NORTHEAST. ALL SEVERE WX INDEXES

OVER THE ENTIRE AREA WITH PW/S RISING TO AROUND 1.50 INCHES. WINDS
PRETTY UNI-DIRECTIONAL OUT OF THE SOUTHWEST AND FREEZING LEVEL WAS
14,500 ON THE APX 12Z SOUNDING. ONE LIMITING FACTOR IS THAT ABUNDANT

AFTERNOON WITH THE MAIN THUNDERSTORM THREAT OF STRONG WINDS AND HAIL
TO AROUND 1 INCH. HAZARDOUS WEATHER STATEMENT ADDRESSES THESE TWO
