AREA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE JACKSON MS
1035 AM CDT FRI JUN 27 1997

AFTERNOON HEATING AND WEAK UPPER LEVEL DISTURBANCES WILL PROVIDE ENOUGH
ENERGY TODAY TO INDUCE SCATTERED THUNDERSTORM DEVELOPMENT...MAINLY
DURING THE AFTERNOOON AND EVENING HOURS.  THE POTENTIAL FOR STRONG
THUNDERSTORMS IS GREATEST OVER THE NORTHERN COUNTIES WHERE A NEAR
STATIONARY SURFACE BOUNDARY WILL LINGER AROUND THE TENNESSEE-MISSISSIPPI
BORDER.

WITH ABUNDANT LOWER- AND MID-LEVEL MOISTURE OVER THE LOWER MISSISSIPPI
RIVER VALLEY...SCATTERED THUNDERSTORM ACTIVITY IS POSSIBLE OVER THE
ENTIRE AREA.  A FEW THUNDERSTORMS COULD REACH SEVERE CRITERIA...WITH
THE PRIMARY THREATS BEING DOWNBURST WINDS AND LOCALLY HEAVY RAINFALL.

ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND EMERGENCY
MANAGEMENT PERSONNEL WILL PROBABLY NOT BE NECESSARY TODAY OR TONIGHT.
