AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
200 AM CDT FRI JUN 23 2006

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...
MAIN FORECAST HIGHLIGHTS IN THE SHORT TERM WILL BE POSSIBILITY OF
CONVECTION TODAY THROUGH SATURDAY.

CURRENTLY...WEAK SHORTWAVE ENERGY MOVING ALONG NORTHWESTERLY FLOW
ALOFT AND SURFACE LOW PRESSURE OVER EASTERN MONTANA PRODUCING
SCATTERED SHOWERS AND A FEW THUNDERSTORMS THIS MORNING. ACTIVITY WAS
OVER WESTERN ND AND SPREADING EASTERLY.

WEAK SHORTWAVE ENERGY WILL CONTINUE TO MOVE THROUGH THE FORECAST
AREA TODAY THROUGH SATURDAY...PRODUCING AREAS OF SHOWERS AND
THUNDERSTORMS. FOR TODAY...WEAK SURFACE LOW PRESSURE OVER EASTERN
MONTANA WILL SLIDE SOUTHEAST INTO THE CENTRAL PLAINS. GOOD
INSTABILITY ACROSS THE REGION COMBINED WITH VORT ENERGY ALOFT WILL
BRING A DECENT CHANCE OF SHOWERS AND THUNDERSTORMS TODAY AND
TONIGHT. ANY STRONG STORMS SHOULD BE CONFINED TO THE FAR SOUTHERN
COUNTIES OF THE CWA WHERE THE BEST LIFT IS LOCATED. INSTABILITY AND
UPPER LEVEL DISTURBANCES CONTINUES INTO SATURDAY MORNING AND
AFTERNOON BRINGING A CONTINUED CHANCE OF PRECIPITATION. BY SATURDAY
NIGHT AND INTO SUNDAY...SURFACE HIGH PRESSURE WILL MOVE OVER THE
NORTHERN PLAINS BRINGING DRY AND SEASONABLE WEATHER.

NOT ANTICIPATING FIRE WEATHER CONCERNS THIS WEEKEND WITH
TEMPERATURES AT OR SLIGHTLY BELOW SEASONAL...AND WINDS MAINLY ON THE
LIGHT SIDE. ALTHOUGH FUELS OVER SOUTH CENTRAL NORTH DAKOTA CONTINUE
TO BE VERY DRY.

.LONG TERM...MONDAY THROUGH FRIDAY NIGHT...
GFS HAS GONE A BIT ANOMALOUS ALL OF A SUDDEN BY PUSHING A HUDSON
BAY LOW DOWN OVER THE WESTERN GREAT LAKES NEXT MID WEEK. THIS WOULD
COOL TEMPERATURES AND INCREASE CHANCES OF THUNDERSHOWERS. CURRENT
ECMWF DOES NOT SUPPORT THIS...AND NEITHER DOES THE UK MET. SO I WILL
KEEP IT WARM AND DRY FOR THE TIME BEING.

.BIS WATCHES/WARNINGS/ADVISORIES...
NONE.
