AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE GREAT FALLS MT 254 AM MDT FRI JUL 22 2005 .DISCUSSION... TODAY THROUGH SUNDAY...AN UPPER LEVEL RIDGE WILL BE OVER EASTERN MONTANA TODAY WITH SOUTHWEST FLOW ALOFT OVER MY CWA. SATELLITE IMAGERY IS SHOWING MID AND HIGH LEVEL MOISTURE FLOWING OVER THE GREAT BASIN INTO MY SOUTHWEST ZONES. MODELS ARE ALSO IN GOOD AGREEMENT MOVING A SURFACE LOW FROM THE PACIFIC NORTHWEST INTO CENTRAL MONTANA BY THIS EVENING THEN PUSHING A COLD FRONT THROUGH MY CWA OVERNIGHT. THIS SCENARIO IS SLOWER THAN PREVIOUS MODEL RUNS AND ALLOWS SUSTAINED EAST WINDS TO ADVECT HIGHER DEWPOINTS INTO MY CWA BEFORE CONVECTION HAS A CHANCE TO FIRE. AS A RESULT...BELIEVE THAT THUNDERSTORMS ACROSS MUCH OF MY CWA MAY BE A BIT WETTER THAN WAS PREVIOUSLY FORECAST...ALTHOUGH SHEAR PROFILES STILL SUGGEST THAT GUSTY WINDS WILL ACCOMPANY ANY STORMS THAT DEVELOP. EVEN THOUGH IT APPEARS THAT DRY THUNDERSTORMS WILL NOT BE AN ISSUE...DUE TO THE RECENT HOT AND DRY SPELL...WILL CONTINUE THE RED FLAG WARNING AND WILL UPGRADE THE WATCH IN MY EASTERN ZONES TO A WARNING. THE UPPER RIDGE IS FLATTENED TONIGHT AND A NEARLY ZONAL FLOW ALOFT SETS UP FOR THE REMAINDER OF THE SHORT TERM. PATTERN WILL SUPPORT A GENERALLY DRY REGIME WITH WEST WINDS AND TEMPERATURES REMAINING NEAR OR SLIGHTLY ABOVE SEASONAL NORMS. MPJ SUNDAY NIGHT THROUGH FRIDAY...QUIET CONDITIONS WILL BE THE RULE OF THUMB FOR THE EXTENDED FORECAST. NORTHWEST FLOW ALOFT WILL BRING COOLER TEMPERATURES TO THE AREA MONDAY AND TUESDAY. HIGHS WILL ACTUALLY BE SLIGHTLY BELOW NORMAL FOR THIS TIME OF YEAR. BY WEDNESDAY FLOW ALOFT BECOMES WESTERLY ALLOWING WARMER AIR BACK INTO THE REGION. HIGHS WILL CLIMB TO NEAR NORMAL AND REMAIN THERE INTO LATE NEXT WEEK. NORMAL HIGHS FOR THIS TIME OF YEAR ARE IN THE LOWER TO MID 80S. MEIER && .AVIATION... UPDATED AT 0500Z. WITH A SHORTWAVE TROUGH APPROACHING MONTANA FROM THE WEST...THE WESTERLY FLOW ALOFT WILL BECOME MORE SOUTHWESTERLY THROUGH 06Z SATURDAY. MONSOONAL MOISTURE MOVING INTO THE STATE FROM THE SOUTHWEST WILL BRING INCREASING MID AND HIGH LEVEL CLOUDINESS AND ISOLATED SHOWERS INTO SOUTHWEST AND NORTH CENTRAL MONTANA THROUGH 18Z FRIDAY. THE AIRMASS WILL DESTABILIZE AFTER 18Z FRIDAY AS THE SHORTWAVE APPROACHES THE STATE. DISTURBANCES IN THE SOUTHWEST FLOW WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS TO THE AREA...WITH SOME OF THE STORMS BEING DRY. EASTERLY/SOUTHEASTERLY WILL BECOME MORE SOUTHERLY AFTER 18Z AS A COLD FRONT APPROACHES FROM THE WEST...THEN WINDS WILL BECOME MORE WESTERLY BEHIND THE FRONT AFTER 00Z.
