NWS Glasgow, MT wrote its last area forecast discussion before the first event at Jun 3, 1:22 PM MST, 3 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 222 PM MDT TUE JUN 3 2014 .SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH THURSDAY... AS OF 1330 THIS AFTERNOON AN APPROACHING SHORTWAVE DISTURBANCE HAS TRIGGERED SHOWERS AND THUNDERSTORMS ACROSS CENTRAL MONTANA. EXPECT THIS TREND TO CONTINUE AS THE SHORTWAVE TRACKS EASTWARD INTO NORTHEAST MONTANA. A MARGINAL SHEAR ENVIRONMENT EXISTS ACROSS MOST OF NORTHEAST MONTANA WHICH WILL HELP LIMIT SEVERE POTENTIAL. THE EXCEPTION TO THIS IS FAR SOUTHERN WIBAUX AND PRAIRIE COUNTIES WHERE A BIT MORE FAVORABLE SHEAR EXISTS AND STORMS WILL HAVE TO BE CLOSELY MONITORED. EXPECT THE CURRENT TRENDS TO CONTINUE THROUGH THE EVENING HOURS...WITH MUCH OF NORTHEAST MONTANA SEEING SHOWERS AND THUNDERSTORMS. STORMS WILL LIFT TO THE NORTHEAST WITH THE MOVEMENT OF THE SHORTWAVE FEATURE AFTER MIDNIGHT TONIGHT...TAKING THE BEST POTENTIAL FOR SHOWERS AND ISOLATED THUNDERSTORMS WITH IT. WITH AMPLE CLOUD COVER OVERNIGHT EXPECT MIN TEMPS WILL REMAIN ON THE WARM SIDE. WEDNESDAY AN UPPER TROUGH WILL REMAIN OVERHEAD...DRIVING CYCLONIC FLOW AND SOME CONTINUED POTENTIAL FOR SCATTERED SHOWERS AND THUNDERSTORMS. STRONGER ENERGY WILL EXIST OVER THE FAR NORTHEAST CORNER OF THE TREASURE STATE...CREATING THE BEST CONVECTIVE POTENTIAL THERE. GUSTY WEST-NORTHWEST WINDS WILL BE PRESENT DURING THE AFTERNOON HOURS. AT THIS TIME THEY LOOK MARGINAL FOR A LAKE WIND ADVISORY...BUT IT WILL NEED TO BE MONITORED. WEDNESDAY NIGHT INTO THURSDAY MORNING WEAK RIDGING WILL BUILD IN BEHIND THE EXITING UPPER TROUGH...ALLOWING CONDITIONS TO DRY FROM WEST TO EAST THROUGH THE EVENING HOURS. SOME PARTIAL CLEARING IS EXPECTED OVERNIGHT...WHICH WILL ALLOW TEMPS TO FALL TO NEAR SEASONAL NORMALS. THURSDAY AFTERNOON A MAINLY DRY COLD FRONT WILL PUSH THROUGH NORTHEAST MONTANA...BRINGING GUSTY NORTHWESTERLY WINDS. AT THIS POINT A LAKE WIND ADVISORY LOOKS LIKE A GOOD BET FOR FORT PECK LAKE. DO NOT EXPECT MUCH IN THE WAY OF PRECIP WITH THE FRONT...BUT THE SOUTH AND EAST COULD PICK UP AN ISOLATED SHOWER/THUNDERSTORM OR TWO DURING THE AFTERNOON. EXPECT PREFRONTAL COMPRESSION TO ALLOW TEMPS TO SPIKE UP IN THE LOWER YELLOWSTONE VALLEY EARLY THURSDAY AFTERNOON...THUS TRENDED UP MAX TEMPS. GILCHRIST .LONG TERM...THURSDAY NIGHT THROUGH TUESDAY... AFTERNOON UPDATE... DUE TO RADAR CONCERNS CHANGES WERE KEPT TO A MINIMUM THIS AFTERNOON. HOWEVER... USING THE MODEL SPECTRUM TOOL HAVE RAISED WINDS SPEEDS BEYOND ABOUT SUNDAY NIGHT AND SKY TOTALS FROM THURSDAY NIGHT TO SATURDAY TO BE IN LINE WITH THE TOTAL MODEL SPREADS. GAH PREVIOUS LONG TERM DISCUSSION... THURSDAY NIGHT BEGINS WITH A VIGOROUS TROUGH SWINGING ACROSS CENTRAL SASKATCHEWAN THAT SENDS A COLD FRONT SOUTH INTO NORTHEAST MONTANA. INITIALLY...WIND BEHIND THE FRONT WILL BECOME GUSTY FROM THE NORTHWEST. THE CANADIAN WAVE IS SPLIT OFF FROM A MORE SHALLOW SHORTWAVE MOVING INTO THE PAC-NW. THE COMBINATION OF THE TWO WAVES SETS UP AN AREA MAINLY SOUTH OF THE MISSOURI RIVER FOR RAIN SHOWERS INTO FRIDAY. THE AIR-MASS BEHIND THE FRONT IS RATHER COOL. THEREFORE WITH THE SECOND WAVE MOVING THROUGH THE LOCAL REGION TEMPERATURES ARE EXPECTED TO DROP AS MUCH AS 5F-10F BELOW NORMAL FRIDAY AND INTO SATURDAY. BEYOND SATURDAY...MODELS HAD BEEN TOTALLY OUT OF PHASE IN PREVIOUS RUNS. BUT THE 00Z GFS BEGAN TO LINE UP BETTER WITH THE EC... ALTHOUGH TIMING IS OFF BY AROUND 24-HOURS. THEREFORE CONFIDENCE IMPROVES FOR THE EC SOLUTION. SATURDAY NIGHT...A NARROW QUICK MOVING RIDGE MOVES ACROSS THE REGION TO BRING A BRIEF WARM-UP. HOWEVER BEHIND THE RIDGE THE EC SENDS A CLIPPER OVER THE DIVIDE. THE GFS ALSO SHOWS THIS SHORT-WAVE BUT DELAYED BY ABOUT A DAY. TIMING AT THIS POINT FALLS APART BETWEEN THE GFS AND EC. SO BETWEEN SUNDAY NIGHT AND MONDAY NIGHT THE TROUGH WILL BRING IN RAIN SHOWERS AND THUNDERSTORMS. IT IS TOO SOON TO DETERMINE STORM INTENSITY SINCE MUCH OF ITS STRENGTH WILL BE DIURNALLY DRIVEN. THE CURRENT GFS SOLUTION MIGHT ALSO BE TOO WARM FOR EARLY NEXT WEEK. SCT && .AVIATION... FLIGHT CATEGORY: VFR. ISOLATED MVFR POSSIBLE DUE TO THUNDERSTORMS. SYNOPSIS: AN UPPER LEVEL TROUGH IS MOVING THROUGH MONTANA THIS AFTERNOON. THIS HAS BROUGHT WIDESPREAD INSTABILITY FOR GENERAL THUNDERSTORMS AND RAIN SHOWERS THIS AFTERNOON AND EVENING. SOME OF THE CONVECTIVE PARAMETERS ARE SIGNIFICANT ENOUGH TO SAY THAT THERE IS THE POSSIBILITY OF A STRONG CELL OR TWO DEVELOPING. THE STRONGEST UNSTABLE REGION WILL BE MORE TOWARD SOUTHEAST MONTANA AND WYOMING...INTO THE CENTRAL PLAINS WHERE SUPERCELL DEVELOPMENT IS EXPECTED. AFTER ABOUT 06Z MOST OF THE THUNDER IS ANTICIPATED TO HAVE CALMED. HOWEVER... RAIN SHOWERS WILL CONTINUE INTO WEDNESDAY. AREA WINDS: OUT OF THE SOUTHEAST AROUND 10-15KT THIS AFTERNOON. WIND WILL SLOWLY BACK AROUND TO THE WEST TONIGHT. GAH && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && WEATHER.GOV/GLASGOW
