AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
250 PM CDT WED AUG 24 2005

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT
MORNING NAM INDICATES THAT THIS AFTERNOONS/EVENINGS CONVECTION
WILL TAKE OFF ON A LINE 20 TO 50 MILES WEST OF BISMARCK/MINOT. BY
THURSDAY MORNING THE ACTIVITY WILL BE EAST OF OUR FORECAST
AREA...BUT STILL OVER EASTERN NORTH DAKOTA. A DRY SLOT WILL BE
ENTERING THE WEST...BUT THE COLD CORE UPPER LOW IN CANADA WILL
SPREAD SOME CLOUDS AND LIGHT SHOWERS ALONG THE INTERNATIONAL BORDER.
NORMAL NIGHTTIME COOLING WILL END THE SHOWERS AND DECREASE THE
CLOUDINESS OVER THE NORTH THURSDAY NIGHT. FRIDAY WILL BE A REPLAY OF
THURSDAY...EXCEPT THE UPPER LOW WILL BE FURTHER NORTH OF THE BORDER
SO THERE WONT BE SHOWERS AND THE CLOUDINESS WILL BE LESS OVER MY
NORTHERN ZONES. SATURDAY WILL BE DRY...HOWEVER A SHORT WAVE SPOKE
ORBITING THE UPPER LOW IN MANITOBA WILL HOLD TEMPERATURES BACK A
BIT...AND MAY INDUCE SOME PARTIAL CLOUDINESS IN WHAT OTHERWISE WOULD
BE A SUNNY AND MILD PATTERN.

.LONG TERM...SUNDAY THROUGH WEDNESDAY NIGHT
A MID LEVEL SHORT WAVE RIDGE BUILDS INTO THE NORTHERN PLAINS FOR THE
LATTER PART OF THE WEEKEND AND INTO EARLY NEXT WEEK. EXPECT DRY AND
MILD WEATHER THROUGH MONDAY NIGHT. BY MONDAY NIGHT INTO
TUESDAY...UPPER LEVEL FLOW SWITCHES TO SOUTHWESTERLY AS THE SHORT
LIVED RIDGE MOVES OFF TO THE EAST. WILL THUS SEE A RETURN TO AN
ACTIVE WEATHER PATTERN THROUGH THE REMAINDER OF THE EXTENDED.
CURRENT GRIDS ARE REFLECTING THIS WELL...SO MADE MINIMAL CHANGES TO
ALL GRID PARAMETERS.
