AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT ISSUED BY NATIONAL WEATHER SERVICE MISSOULA MT 229 PM MDT THU JUN 23 2005 .DISCUSSION... TONIGHT THROUGH SATURDAY NIGHT...UPPER TROUGH MOVING THROUGH ALBERTA/SASKATCHEWAN THIS AFTERNOON IS BRINGING A DRIER MORE STABLE WESTERLY FLOW TO MOST OF THE FORECAST AREA THIS AFTERNOON. THE EXCEPTION IS SOUTHWEST MONTANA WHERE LOW AND MID LEVEL CONVERGENCE ALONG A WEAK FRONTAL BOUNDARY IS THE FOCUS FOR THUNDERSTORM ACTIVITY THIS AFTERNOON AND TONIGHT. CONDITIONS ARE MODERATELY UNSTABLE WITH MODEST MID AND UPPER LEVEL MOISTURE FEEDING INTO THE REGION FROM THE SOUTHWEST. THERE IS A POTENTIAL FOR GUSTY WINDS AND SMALL HAIL FROM STRONGER STORMS. THE CONVECTION WILL GRADUALLY DIMINISH AND SHIFT EAST THIS EVENING...BUT A FEW SHOWERS OR THUNDERSTORMS COULD REDEVELOP UNTIL AFTER MIDNIGHT NEAR YELLOWSTONE PARK AS A REGION OF MID-LEVEL INSTABILITY SLOWLY SHIFTS EAST. ON FRIDAY AND SATURDAY ANOTHER UPPER THROUGH WILL BEGIN TO DIG INTO THE PACIFIC NORTHWEST BACKING THE UPPER LEVEL FLOW TO THE SOUTHWEST. THIS WILL ADVECT MORE UNSTABLE AIR ALONG WITH SOME MID AND HIGH LEVEL MOISTURE INTO THE REGION. AT THE SURFACE A RETURN SOUTHEASTERLY FLOW AROUND A SURFACE HIGH WILL BRING AN INCREASE IN LOW LEVEL MOISTURE FROM THE EAST. AN INCREASING THREAT OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS WILL OCCUR LATE FRIDAY AFTERNOON AND ESPECIALLY SATURDAY INTO SATURDAY NIGHT. TEMPERATURES WILL REMAIN SEASONABLE. SUNDAY THROUGH THURSDAY...LONG RANGE MODELS NOW IN A LITTLE BETTER AGREEMENT FOR DEEPER PACIFIC TROUGH AND UPPER LOW PRESSURE TO MOVE IN TO THE NORTHWESTERN US EARLY NEXT WEEK. THIS COULD MEAN WETTER PERIOD SUNDAY NIGHT THROUGH TUESDAY FOR THE AREA. SOME UNCERTAINTIES REMAIN AS TO TIMING...COLD FRONT WITH THIS PACIFIC SYSTEM...SO FORECAST REFLECT TREND UPWARD FOR CHANCE OF PRECIPITATION. FOR MID WEEK... ONLY SLIGHT CHANCES AS MORE WEST TO EAST UPPER LEVEL FLOW IS EXPECTED TO DEVELOP. && .AVIATION...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON AND EVENING ACROSS SOUTHWEST MONTANA.
