AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 315 AM CDT WED JUN 6 2007 .SHORT TERM...TODAY THROUGH FRIDAY NIGHT... THE GFS AND NAM CONTINUE TO INDICATE POTENTIAL HEAVY RAIN THIS EVENING THROUGH THURSDAY MORNING AS THE SURFACE LOW MOVES ACROSS THE CENTRAL PLAINS ALTHOUGH THEY DIFFER ON PLACEMENT OF HEAVIEST RAIN. STILL HEAVY RAIN LOOKS LIKELY WITH AMOUNTS OF 2 TO 3 INCHES POSSIBLE IN SOME AREAS.

A LINE OF THUNDERSTORMS IS JUST NOW MOVING INTO WESTERN ND...BUT AIRMASS BECOMES MORE STABLE WITH EASTWARD MOVEMENT.
