NWS Great Falls, MT wrote its last area forecast discussion before the first event at Feb 20, 10:45 PM MST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT 1045 PM MST MON FEB 20 2012 AVIATION SECTION UPDATED .UPDATE... TONIGHT...MOST SNOWFALL HAS BEEN OCCURRING OVER THE EASTERN PORTIONS OF THE CWA...MAINLY IN SOUTHWEST AND CENTRAL MONTANA. PARTIAL CLEARING TO THE WEST HAS ALLOWED TEMPS TO DROP QUICKLY THIS EVENING. AN UPPER LEVEL DISTURBANCE IS MOVING INTO THE HIGH PRESSURE WEST OF THE DIVIDE. MOISTURE AHEAD OF THIS SYSTEM WILL INCREASE THE CLOUD COVER...AND STRONG WINDS ASSOCIATED WITH IT WILL ALSO SPREAD INTO THE AREA. HAVE DROPPED MOST TEMPS ACROSS THE ZONES. FALLING TEMPERATURES ACROSS THE ROCKIES AND ADJACENT PLAINS WILL BE MODERATED BY THE INCREASING CLOUD COVER AND WINDS...AREAS FARTHER EAST WILL SEE LOWER TEMPS. ALSO FRESHENED POPS...SNOW ACROSS CENTRAL ZONES WILL CONTINUE TO WEAKEN WHILE WEST YELLOWSTONE SHOULD CONTINUE WITH AT LEAST LIGHT SNOW THROUGH THE NIGHT. HIGH WIND HIGH LIGHTS ARE BEING CONTINUED...WILL ALSO KEEP THE CURRENT ADVISORY FOR SNOW. ZELZER && .AVIATION... UPDATED 0545Z. WIDESPREAD LIGHT SNOW SHOWERS WILL AFFECT MUCH OF THE ROCKY MOUNTAIN FRONT...CENTRAL AND SOUTHWEST MONTANA. EXPECT WIDESPREAD IFR CONDITIONS ALONG MOUNTAINS OBSCURED IN THESE AREAS. THE PRECIP SHOULD CHANGE TO MOSTLY RAIN IN THE VALLEYS AFTER 18Z TUESDAY. GUSTY WEST WINDS WILL DEVELOP BY LATE TUESDAY MORNING OVER THE NORTHERN PLAINS. EXPECT PRECIP TO BECOME A BIT MORE WIDESPREAD OVER NORTH CENTRAL MONTANA ON WEDNESDAY...AS A STRONGER PACIFIC COLD FRONT MOVES THROUGH THE REGION. BRUSDA && .PREV DISCUSSION... /ISSUED 450 PM MST MON FEB 20 2012/ TONIGHT THROUGH WEDNESDAY...CLOUDY SKIES WITH MOUNTAIN SNOW SHOWERS ARE EXPECTED THROUGH TONIGHT THOUGH LITTLE SNOW ACCUMULATION IS EXPECTED AS OUR OVERALL PATTERN SHIFTS AND BECOMES MORE ACTIVE. WINDS WILL INCREASE ALONG THE ROCKY MOUNTAIN FRONT AND EASTERN GLACIER COUNTY TONIGHT SO HAVE UPGRADED THE HIGH WIND WATCH TO A WARNING FOR THESE AREAS. A HIGH WIND WATCH REMAINS IN EFFECT FOR THE NORTH-CENTRAL PLAINS THOUGH CONFIDENCE IS INCREASING REGARDING THIS EVENT ON TUESDAY NIGHT AND WEDNESDAY. AS UNSETTLED WEST-NORTHWEST FLOW AND SHORTWAVE ENERGY MOVE OVER THE AREA...LIGHT SNOW WILL INCREASE OVER THE HIGHER ELEVATIONS ALONG THE ROCKY MOUNTAIN FRONT AND SOUTHWEST MONTANA WITH MODERATE SNOW ACCUMULATIONS POSSIBLE BEGINNING TUESDAY THROUGH WEDNESDAY. WINTER HIGHLIGHTS MAY BE NEEDED FOR THESE AREAS AND WILL CONTINUE TO MONITOR. OVER THE PLAINS...WINDS WILL LIMIT PRECIPITATION...HOWEVER A RAIN AND/OR SNOW SHOWERS CHANCES WILL INCREASE AS PACIFIC MOISTURE INCREASES ACROSS THE AREA. DURING THE DAY...TEMPERATURES OVER THE PLAINS WILL BE WARM ENOUGH FOR RAIN BUT AT NIGHT A MIX OF RAIN AND/OR SNOW IS POSSIBLE WITH ALL SNOW EXPECTED IN THE MOUNTAINS. MLV WEDNESDAY NIGHT THROUGH MONDAY NIGHT...FORECAST MODELS ARE IN FAIRLY GOOD AGREEMENT WITH THE OVERALL TREND THROUGH THE PERIOD...BUT THERE ARE TIMING DIFFERENCES REGARDING THE LATE-WEEK SYSTEM. STRONG WINDS AND MAINLY MOUNTAIN PRECIPITATION WILL LINGER INTO WEDNESDAY NIGHT IN THE WAKE OF THE EXITING SYSTEM. ENERGY AND MOISTURE IN THE RESULTING NORTHWEST FLOW ALOFT WILL KEEP A GOOD CHANCE OF SNOW IN THE MOUNTAINS THURSDAY THROUGH FRIDAY...BUT BREEZY WEST-NORTHWEST SURFACE WINDS WILL LIMIT THE PLAINS OF NORTH CENTRAL MONTANA TO ONLY A SLIGHT CHANCE. THE NEXT SYSTEM THAT WILL AFFECT THE AREA WILL BE AN UPPER LEVEL TROUGH OF LOW PRESSURE THAT WILL ORIGINATE IN THE GULF OF ALASKA ON THURSDAY AND MOVE THROUGH THE AREA OVER THE WEEKEND. MOST SYSTEMS HAVE SPLIT AS THEY MOVE THROUGH THE AREA THIS WINTER...LESSENING THE IMPACT OF THEM. HOWEVER...THIS SYSTEM APPEARS TO STAY MORE INTACT THAN THESE PREVIOUS ONES. THE GFS IS THE QUICKEST OF THE MODELS REGARDING THE TIMING OF THE PASSAGE OF THE SYSTEM...BRINGING THE SNOWFALL AND COLDER AIR INTO THE AREA BY SATURDAY NIGHT. THE GEM/ECMWF ARE SLOWER WITH ITS OVERALL PROGRESSION...WITH THE COLD AIR NOT MAKING IT INTO THE AREA UNTIL SUNDAY NIGHT. REGARDLESS...THESE LATTER TWO FORECAST MODELS DO BRING PRECIPITATION INTO THE AREA AHEAD OF THE SYSTEM WITH TIMING SIMILAR TO THE GFS. WITH THE BETTER RUN-TO-RUN CONSISTENCY OF THE GFS...AM GOING TO BASE THE FORECAST FOR THE WEEKEND/EARLY WEEK PERIOD MORE ON THAT MODEL. WITH THIS SYSTEM...THERE IS A POTENTIAL FOR WIDESPREAD MEASURABLE SNOWFALL BEGINNING FRIDAY NIGHT AND LINGERING THROUGH THE END OF THIS PERIOD. THE PERIOD WITH THE BEST POTENTIAL FOR ACCUMULATING SNOWFALL SEEMS TO BE SATURDAY AND SATURDAY NIGHT AT THIS TIME...WITH THE CHANCE DECREASING THROUGH THE END OF THE PERIOD AS THE SYSTEM SLOWLY EXITS THE AREA. THE ASSOCIATED COLD FRONTAL PASSAGE (WITH MODEL TIMING SIMILAR TO THAT OF THE OVERALL SYSTEM) WILL USHER IN MUCH COOLER THAN NORMAL TEMPERATURES...WITH MOSTLY SINGLE DIGIT LOWS AND TEENS FOR HIGHS. WINDS AHEAD OF AND BEHIND THE FRONT MAY ALSO BECOME QUITE BREEZY AND MAY CREATE ADDITIONAL WEATHER PROBLEMS. THIS SITUATION WILL CONTINUE TO BE MONITORED AS IT EVOLVES OVER THE NEXT FEW DAYS FOR POSSIBLE WINTER WEATHER HIGHLIGHTS. COULSTON && .PRELIMINARY POINT TEMPS/POPS...
