SOUTHWEST AND NORTH CENTRAL MONTANA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT 245 PM MDT WED JUN 27 2001 AIR EVEN MORE MOIST THAN ANTICIPATED ACROSS MOST OF THE CWA THIS AFTERNOON WITH LOW LEVEL EASTERLY FLOW. MSAS PLOT AND MODIFIED 12Z SOUNDING INDICATING AN LI OF -6 OVER GTF AT 2 PM. THE QUESTION IS... WHERE WILL THE TRIGGER COME FROM TO START CONVECTION? FRONT AND ASSOCIATED SHOWERS LYING ALONG THE WESTERN BORDER IS THE BEST POSSIBILITY. THIS FEATURE SEEMS TO BE MOVING SLOWER THAT MODELS HAD INDICATED...BUT CONVECTION ALSO OCCURRING AHEAD OF IT. STRONGER SHORTWAVE IN WYOMING WILL MOVE INTO EASTERN MONTANA AND NOT BE A FACTOR IN OUR FORECAST. FLOW ALOFT BECOMES INCREASING DIFFLUENT OVER THE NEXT 6-12 HOURS...SO WILL CONTINUE WITH SCATTERED POPS TONIGHT... EXCEPT FOR NORTHEAST ZONES WHERE LIKELY POPS WILL BE USED. BEST MOISTURE CONVERGENCE OCCURS THERE AROUND 06Z...AND WITH THE SUN BREAKING OUT THIS AFTERNOON...TEMPERATURES MAY STILL BE IN THE 70S BY THE TIME THE BOUNDARY MAKES IT THERE. FOR THURSDAY AND FRIDAY...UPPER FLOW BECOMES MORE CYCLONIC...ALTHOUGH RESIDUAL INSTABILITY AND WEAK SHORTWAVES AFFECTING THE SOUTHEAST ZONES WILL ALLOW FOR ISOLATED THUNDERSTORMS DURING THE AFTERNOON AND EVENING. POMEROY EXTENDED...UPPER LEVEL LOW PRESSURE TROUGH REMAINS CENTERED OFF BC COAST EARLY IN PERIOD WITH HIGH PRESSURE RIDGE CENTERED OVER FOUR CORNERS REGION. TROUGH CONTINUES TO SPIN DISTURBANCES INLAND WITH SOUTHWEST FLOW OVER PACIFIC NORTHWEST STEERING THE DISTURBANCES INTO WESTERN MONTANA. THE STRONGEST OF THESE WILL BRUSH ACROSS THE NORTHWEST AND NORTHERN PORTION OF THE CWA SATURDAY NIGHT AND SUNDAY FOR THE BEST CHANCE OF SHOWERS. AS THIS DISTURBANCE EXITS...THE HIGH PRESSURE RIDGE BEGINS STRENGTHENING AND RETROGRADING...WITH THE CENTER OVER NORTHWEST WY AND THE AXIS SHIFTING TO THE MT/ID BORDER. THIS SHIFT WILL KEEP TEMPERATURES SEASONABLY WARM WITH ONLY ISOLATED AFTERNOON SHOWERS OR THUNDERSTORMS OVER THE MOUNTAINS.
