SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE BISMARCK ND
445 AM CDT TUE SEP 5 2000

...THERE IS A CHANCE OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT OVER NORTHWEST AND NORTH CENTRAL NORTH DAKOTA...

FORECAST...LOOK FOR SCATTERED THUNDERSTORMS THIS AFTERNOON AND
TONIGHT OVER THE REGION. A FEW STORMS MAY BECOME SEVERE IN THE
NORTHWEST AND NORTH CENTRAL PART OF THE STATE.

DISCUSSION...LOW PRESSURE IN SOUTHEAST MONTANA...WITH A TROUGH
EXTENDING NORTHEAST INTO NORTHWEST NORTH DAKOTA WILL BE THE FOCUS
FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND TONIGHT. A WEAK
UPPER LEVEL IMPULSE MOVING THROUGH WESTERN NORTH DAKOTA MAY PRODUCE
SCATTERED THUNDERSTORMS THIS AFTERNOON. AN APPROACHING UPPER LEVEL
TROUGH WILL PROVIDE A BETTER CHANCE OF THUNDERSTORMS TONIGHT. THERE
MAY BE SUFFICIENT LOW LEVEL FORCING AND CAPE TO PRODUCE A FEW SEVERE
THUNDERSTORMS IN THE NORTHWEST AND NORTH CENTRAL PART OF THE
STATE...WHERE THE MAIN THREAT WOULD BE LARGE HAIL. OVER THE
SOUTHWEST AND SOUTH CENTRAL PART OF THE STATE WARM MID LEVEL
TEMPERATURES SHOULD KEEP ANY THUNDERSTORMS BELOW SEVERE LEVELS.

WEATHER SPOTTERS MAY BE NEEDED IN NORTHWEST AND NORTH CENTRAL NORTH
DAKOTA THIS AFTERNOON AND TONIGHT.

THIS PRODUCT IS FOR PLANNING PURPOSES ONLY. STAY TUNED TO NOAA
WEATHER RADIO FOR UPDATED FORECASTS.
