Area forecast discussion, Jun 25, 1:43 PM MST, 4 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 243 PM MDT WED JUN 25 2014 .SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH FRIDAY... UPPER LEVEL DISTURBANCES IN A SOUTHWEST FLOW ALOFT ARE BEGINNING TO TRIGGER THUNDERSTORMS ACROSS PHILLIPS AND PETROLEUM COUNTIES. EXPECT THIS TREND TO CONTINUE AS THE ATMOSPHERE FURTHER DESTABILIZES AS THE AFTERNOON WEARS ON. SOUTHEAST SURFACE WINDS CONTINUE TO ADVECT IN NEAR 60 DEWPOINTS OUT OF THE DAKOTAS WHICH WILL CONTINUE TO RAMP UP PRECIPITABLE WATER VALUES TO NEAR THE 99TH PERCENTILE CLIMATOLOGICALLY. THIS JUICY ATMOSPHERE WILL ALLOW FOR TORRENTIAL RAINFALL FROM ANY STORMS THAT DO DEVELOP. THERE IS ALSO POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS LATE THIS AFTERNOON AND EVENING EAST OF THE MUSSELSHELL RIVER AND SOUTH OF THE MISSOURI RIVER WHERE A MORE FAVORABLE DIRECTIONAL SHEAR ENVIRONMENT EXISTS. STORMS WILL PUSH EASTWARD THROUGH THE EVENING HOURS...AND WILL HAVE LARGELY TAPERED OFF AFTER MIDNIGHT. THURSDAY AFTERNOON AND EVENING CONTINUES TO LOOK VERY FAVORABLE FOR ANOTHER ROUND OF STRONG TO SEVERE THUNDERSTORMS WITH TORRENTIAL RAINFALL ACROSS ALL OF NORTHEAST MONTANA. IN FACT HPC HAS MOST OF NORTHEAST MONTANA IN A SLIGHT RISK IN ITS EXCESSIVE RAINFALL OUTLOOK. WITH ALL THE THREAT FOR FLASH FLOODING DECIDED TO EXPAND THE FLASH FLOOD WATCH FOR TODAY THROUGH THURSDAY EVENING TO COVER ALL OF NORTHEAST MONTANA WITH THE EXCEPTION OF GARFIELD...PETROLEUM...AND SOUTHWEST PHILLIPS COUNTIES WHICH HAVE SEEN MORE DROUGHT LIKE CONDITIONS THIS SPRING. AGAIN RAINFALL AND THUNDERSTORM POTENTIAL WILL TAPER OFF BY EARLY FRIDAY MORNING AS THE SURFACE TROUGH THAT SERVED AS A FOCUSING MECHANISM FOR CONVECTION KICKS OFF TO THE EAST. GILCHRIST .LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY... MADE SOME MINOR ADJUSTMENTS FROM DAY 3 THROUGH DAY 4. LEFT THE REMAINDER OF THE EXTENDED PERIOD ALONE IN ORDER TO SPIN UP READY FOR POSSIBLE SEVERE WEATHER THIS AFTERNOON. BEGINNING FRIDAY AT 12Z...MOST OF THIS HEAVY RAIN SYSTEM WILL HAVE JUST FINISHED WITH OUR CWA. LINGERING LIGHT RAIN SHOWERS MAY STILL HANG AROUND THE PERIPHERY OF THE CWA THROUGH SATURDAY...BUT DO NOT EXPECT MUCH PRECIPITATION. UPPER-LEVEL FLOW WILL GRADUALLY BE CHANGING FROM A SW DIRECTION TO A MORE ZONAL FLOW. MOISTURE AND FORCING FOR ASCENT WILL BE LIMITED. BMICKELSON PREVIOUS LONG TERM DISCUSSION...THE EXTENDED PERIOD BEGINS FRIDAY NIGHT WITH A CLOSED LOW OFF THE COASTLINE OF BRITISH COLUMBIA AND A TROUGH AXIS EXTENSION THROUGH THE PACIFIC NORTHWEST ALL THE WAY THROUGH THE UPPER MIDWEST. MEANWHILE AN AMPLIFIED RIDGE ACROSS THE GREAT LAKES REGION WILL EXTEND NORTH WELL INTO CANADA. THIS WILL LEAVE NORTHEAST MONTANA IN SOUTHWEST FLOW ALOFT AND WITH THE LOCATION BEING TO THE RIGHT OF THE TROUGH AXIS THERE SHOULD CONTINUE TO BE ENOUGH FORCING FOR ASCENT TO MAINTAIN CHANCES FOR SHOWERS/THUNDERSTORMS. THE TROUGH AXIS WILL BECOME SITUATED WELL TO THE EAST OF THE CWA ON SATURDAY AND SATURDAY NIGHT ALLOWING POPS TO BE TAPERED TO SLIGHT CHANCE OVER TIME. EVEN WITH REDUCED FORCING FOR ASCENT DECIDED THAT LEAVING SOME POPS IN THE WX GRIDS IS WARRANTED WITH THE PROXIMITY OF THE UPPER LEVEL LOW. SUNDAY APPEARS DRY AS THE UPPER LEVEL LOW PUSHES NORTHEAST OVER MANITOBA LEAVING MONTANA UNDER ZONAL FLOW ALOFT. WITH MUCH OF THE FORCING FOR ASCENT TO THE NORTH IT IS EXPECTED TO BE A QUIET DAY. MONDAY AND BEYOND...MODELS DEPICT AN UPPER LEVEL RIDGE DEVELOPING ACROSS THE PACIFIC NORTHWEST WHICH WILL DRIVE NORTHWEST FLOW ALOFT THROUGH MONTANA. WILL TRACK WEAK SHORTWAVE FEATURES PROPAGATING THROUGH THE FLOW BUT AS THE ECMWF/GFS DIFFER ON TIMING/PLACEMENT OF THESE FEATURES CONFIDENCE DECREASES. LIGHT PRECIPITATION CHANCES WILL EXIST NONETHELESS THROUGH EARLY AND MIDDLE PORTIONS OF NEXT WEEK SO WILL KEEP POPS NEAR SLIGHT CHANCE FOR NOW. WILL ALSO INTRODUCE...ALBEIT GRADUAL...A WARMING TREND NEAR THE END OF THE LONG RANGE. RIDGING UPSTREAM LEADING TO RISING 500MB HEIGHTS SHOULD ALLOW FOR AT LEAST SOMEWHAT WARMER TEMPERATURES PUSHING INTO THE REGION. MALIAWCO && .AVIATION... SYNOPSIS...INGREDIENTS GATHERING TOGETHER TO SET UP A WET AND ACTIVE PATTERN FOR THIS TAF CYCLE AND BEYOND. A PLENTIFUL SURFACE MOISTURE FEED FROM THE SOUTHEAST...A LOW PRESSURE SYSTEM FROM THE WEST...AND AN UNSTABLE ATMOSPHERE WILL ALL COMBINE TO SET OFF STRONG TO SEVERE THUNDERSTORMS BEGINNING TODAY AND LASTING THROUGH THE EVENING HOURS. FLIGHT CONDITIONS...EXPECT VFR THROUGH EARLY AFTERNOON. THEN MORE WIDESPREAD THUNDERSTORM WILL PUSH THROUGH ALL TERMINALS FROM WEST 21Z THIS AFTERNOON TO EAST 03Z TONIGHT. IF A STRONG STORM HAPPENS TO PASS DIRECTLY OVER A TAF SITE...LIFR CONDITIONS WILL BE POSSIBLE WITH FREQUENT LIGHTNING...SMALL HAIL...AND GUSTY AND VARIABLE WINDS. CONDITIONS WILL IMPROVE TEMPORARILY TONIGHT WITH SOME POSSIBLE LINGERING RAIN SHOWERS FOR KSDY AND KGDV. EXPECT A REPEAT PERFORMANCE THURSDAY EVENING WITH WORSE WIDESPREAD CONDITIONS. BMICKELSON && .GLASGOW WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH THROUGH THURSDAY EVENING FOR CENTRAL AND SOUTHEAST PHILLIPS...CENTRAL AND SOUTHERN VALLEY...DANIELS...
