AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT 345 AM MDT THU NOV 1 2007 .DISCUSSION... TODAY THROUGH SATURDAY...UPPER RIDGE CURRENTLY OVER THE AREA WILL BREAK DOWN LATER THIS MORNING AS AN UPPER TROF SWINGS ACROSS NORTHERN MONTANA. LITTLE MOISTURE IS ASSOCIATED WITH THIS FEATURE WITH ONLY ISOLATED PRECIPITATION EXPECTED OVER THE ROCKY MOUNTAIN FRONT. THE ASSOCIATED SURFACE GRADIENT WITH THIS TROF PASSAGE WILL REMAIN TIGHT THROUGH THE MORNING ALLOWING FOR STRONG AND GUSTY WINDS ALONG THE ROCKY MOUNTAIN FRONT AND THE HIGH WIND WARNING WILL CONTINUE THOUGH IT IS LIKELY IT WILL BE CANCELED BY AFTERNOON. DRY NORTHWEST FLOW ALOFT WILL SET UP OVER THE AREA ON FRIDAY AND CONTINUE THROUGH SATURDAY. TEMPERATURES WILL BE NEAR OR SLIGHTLY BELOW SEASONAL AVERAGES. EMANUEL SATURDAY NIGHT THROUGH THURSDAY NIGHT...AN UPPER LEVEL TROUGH WITH AN ASSOCIATED COLD FRONT WILL APPROACH MONTANA FROM THE NORTHWEST SATURDAY NIGHT. THIS WILL KEEP NORTH CENTRAL AND SOUTHWEST MONTANA UNDER A STRONG WESTERLY FLOW ALOFT...WHICH WILL TRANSLATE INTO STRONG AND GUSTY WEST WINDS ACROSS AT LEAST NORTH CENTRAL MONTANA WITH ABOVE NORMAL TEMPERATURES. A HIGH WIND WATCH MAY NEED TO BE ISSUED FOR THIS PERIOD...AT LEAST FOR THE ROCKY MOUNTAIN FRONT.

TEMPERATURES WILL ALSO FALL BELOW NORMAL DURING THIS TIME AS BREEZY WINDS BECOME MORE NORTHERLY BEHIND THE FRONT. A DRIER NORTHERLY FLOW ALOFT WILL DEVELOP OVER THE AREA MONDAY INTO MONDAY NIGHT...AS SURFACE HIGH PRESSURE MOVES SOUTH OUT OF CANADA. THIS WILL DECREASE THE PRECIPITATION AND WINDS...AND IT WILL CAUSE TEMPERATURES TO REMAIN BELOW NORMAL. MEDIUM RANGE MODELS SEEM TO DIVERGE AT THIS POINT IN THE FORECAST...BUT THE GFS SEEMS TO BE CLOSEST TO ITS PREVAILING TREND DURING THE PREVIOUS RUNS. WILL THEREFORE BASE THE REMAINDER OF THE FORECAST ON ITS SOLUTION. DISTURBANCES WILL FLATTEN THE UPPER LEVEL RIDGE OVER THE WESTERN CONUS...FOR A MOIST WESTERLY FLOW ALOFT OVER THE AREA. THIS WILL BRING A CHANCE OF PRECIPITATION TO THE MOUNTAINS...BUT PLAINS AND VALLEYS SHOULD REMAIN DRY. TEMPERATURES WILL ALSO WARM CLOSER TO NORMAL DURING THIS TIME. COULSTON && .AVIATION...
