HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE BISMARCK ND
430 AM CDT FRI MAY 3 2002

...THERE IS A CHANCE OF THUNDERSTORMS FOR CENTRAL AND SOUTHERN
NORTH DAKOTA THIS AFTERNOON...

FORECAST...THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON ALONG AND EAST
OF A LINE FROM BOWMAN TO MINOT. THE CHANCE WILL CONTINUE INTO THE
EVENING FROM RUGBY TO MANDAN...AND EAST.

DISCUSSION...LOW PRESSURE MOVING THROUGH SOUTHERN CANADA WILL PUSH A 
COLD FRONT INTO NORTH DAKOTA THIS AFTERNOON...WITH AN IMPULSE IN THE 
MIDDLE LEVELS FOLLOWING CLOSELY BEHIND. AIR AHEAD OF THE FRONT WILL 
BE INCREASINGLY UNSTABLE. THE INGREDIENT THAT WILL BE LACKING IS LOW 
LEVEL MOISTURE...HOWEVER...MOISTURE IS FORECAST TO ADVECT IN JUST 
ABOVE THE LOW LEVELS. THIS COULD LEAD TO ELEVATED...HIGH BASED...
THUNDERSTORMS FORMING. THE MAIN THREAT WOULD BE WIND. AT THIS POINT 
IT LOOKS LIKE SOME SMALL HAIL...AND WIND GUSTS TO 45 MPH WILL BE 
POSSIBLE. THESE CONDITIONS WOULD BE BELOW SEVERE LIMITS.

SKYWARN SPOTTERS...ESPECIALLY THOSE SOUTH OF HIGHWAY 2 AND EAST OF 
THE MISSOURI RIVER...SHOULD EXPECT SOME STORMS LATER TODAY... 
POSSIBLY WITH SMALL HAIL AND GUSTY WIND.

THIS PRODUCT IS FOR PLANNING PURPOSES ONLY.
