AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
1016 PM CDT TUE JUL 3 2012

.DISCUSSION...EVENING CONVECTIVE TRENDS CONTINUE TO INDICATE THE
BULK OF THE STRONG TO SEVERE THUNDERSTORMS SHOULD REMAIN ACROSS
NORTHERN NORTH DAKOTA TONIGHT. INSTABILITY ACROSS SOUTHERN NORTH
DAKOTA CONTINUES TO WEAKEN WITH THE LOSS OF DAYTIME HEATING.
HOWEVER...CONVECTION CONTINUES TO FIRE ALONG A FRONTAL OCCLUSION
COINCIDENT WITH SURFACE-6KM SHEAR AROUND 50 KNOTS OVER
NORTHWESTERN NORTH DAKOTA. SOME ADDITIONAL CONVECTION COULD FIRE
ALONG THE BOUNDARY AS THE FRONT MOVES ACROSS THE STATE THROUGH THE
REMAINDER OF THE EVENING. AS A RESULT...WILL ALLOW THE WATCH TO
CONTINUE FOR THE NEXT FEW HOURS. UPDATED GRIDDED/TEXT PRODUCTS
HAVE BEEN SENT.

&&

.AVIATION...A LINE OF STRONG TO SEVERE THUNDERSTORMS WILL PUSH FROM
WEST TO EAST ACROSS WESTERN AND CENTRAL NORTH DAKOTA TONIGHT. THE
MAIN AREA IMPACTED WILL BE ACROSS NORTHERN NORTH DAKOTA (KISN-
KMOT). THE MAIN IMPACT WILL BE AN ABRUPT WIND SHIFT FROM THE
SOUTHEAST TO NORTHWEST WITH GUSTS GENERALLY AROUND 40 KNOTS.
HOWEVER...WOULD NOT BE SURPRISED TO SEE A PEAK WIND GUST AROUND 50
KNOTS. HAIL WILL ALSO BE A POSSIBILITY.

DO NOT THINK THE LINE WILL BUILD AS FAR SOUTH AS I-94.
HOWEVER...CANNOT RULE OUT ANY THUNDERSTORM ACTIVITY TONIGHT ACROSS
SOUTHERN NORTH DAKOTA. AS A RESULT...INDICATED VCTS IN THE
KDIK/KBIS/KJMS TAFS BASED UPON THE EXPECTED FROPA TIMING.
