HAZARDOUS WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
802 PM CST SAT MAR 25 2000

SCATTERED THUNDERSTORMS ARE EXPECTED TO CONTINUE ACROSS NORTH
TEXAS...THROUGH MUCH OF THE NIGHTTIME HOURS. HEAVY RAINFALL IS THE
PRIMARY THREAT WITH THESE THUNDERSTORMS...ALTHOUGH A FEW
THUNDERSTORMS WILL BE CAPABLE OF PRODUCING LARGE HAIL.

A STATIONARY FRONT ACROSS NORTH TEXAS IS EXPECTED TO FOCUS
THUNDERSTORM DEVELOPMENT OVERNIGHT. AN UPPER LEVEL DISTURBANCE
ACROSS WEST TEXAS WILL MOVE EAST OVERNIGHT...AND WILL FURTHER ENHANCE
THUNDERSTORM DEVELOPMENT. VERTICAL WIND...TEMPERATURE...AND MOISTURE
PROFILES SUGGEST THAT THE THUNDERSTORMS WILL BE CAPABLE OF VERY HEAVY
RAINFALL. ISOLATED THUNDERSTORMS MAY PRODUCE LARGE HAIL...ESPECIALLY
ACROSS AREAS ALONG AND SOUTH OF INTERSTATE 20.
