AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GLASGOW MT
919 PM MDT MON MAR 14 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH WEDNESDAY...
UPDATE...FEW TWEAKS FOR COVERAGE ON SHOWERS IN THE SOUTHEAST THIS
EVENING. OTHERWISE VERY MINOR UPDATES THIS EVENING. MAIN CONCERN
REMAINS WITH THE HYDRO SIDE.            PROTON

PREVIOUS DISCUSSION...A VIGOROUS SHORTWAVE SYSTEM AND ITS
ASSOCIATED WEAK COLD FRONT IS CURRENTLY PUSHING THROUGH NORTHEAST
MONTANA. SOME LIGHT RAIN SHOWERS/SPRINKLES HAVE FORMED ALONG THE
FRONT OVER GARFIELD COUNTY. EXPECT THESE SHOWERS TO CONTINUE TO
MOVE TO THE EAST THROUGH THE EARLY EVENING...BRINGING A FEW
ISOLATED SHOWERS TO THE SOUTHEAST ZONES. OTHERWISE EXPECT CLEARING
SKIES TO BUILD IN BEHIND THE EXITING SYSTEM AS HIGH PRESSURE ALOFT
AND AT THE SURFACE BUILD IN FROM THE WEST.

TUESDAY A WARM FRONT ASSOCIATED WITH A DEVELOPING LOW PRESSURE
SYSTEM WILL BUILD IN FROM THE SOUTHWEST...REINFORCING WARM
TEMPERATURES ACROSS NORTHEAST MONTANA. HIGH LEVEL CLOUDS WILL BE
ON THE INCREASE BY THE LATE AFTERNOON AHEAD OF AN APPROACHING
PACIFIC TROUGH.

TUESDAY NIGHT WILL CONTINUE TO SEE THICKENING CLOUDS FROM THE WEST
AS THE PACIFIC TROUGH NEARS. SOME OVERRUNNING LIGHT RAIN WILL
BUILD INTO THE WEST DURING THE EVENING...SPREADING ACROSS THE REST
OF NORTHEAST MONTANA AFTER MIDNIGHT. EXPECT ANOTHER ROUND OF MILD
OVERNIGHT LOWS AS NORTHEAST MONTANA REMAINS IN THE WARM SECTOR OF
THE DEVELOPING SURFACE LOW.

WEDNESDAY THE PACIFIC TROUGH WILL PUSH THROUGH NORTHEAST MONTANA.
SIGNIFICANT MODEL DIFFERENCES REMAIN REGARDING THE TRACK...STRENGTH AND
ULTIMATE IMPACT OF THIS SYSTEM. CONTINUED SCATTERED POPS FOR NOW
GIVEN ITS AVAILABILITY OF SUBTROPICAL MOISTURE OFF THE PACIFIC.
EXPECT ANOTHER WEAK COLD FRONT THAT WILL DO LITTLE MORE THEN
INCREASE WINDS AND PROVIDE BETTER MIXING FOR WARMER TEMPERATURES.
GILCHRIST

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
NOT TOO MANY CHANGES TO THE LONG TERM FORECAST JUST A FEW TWEAKS.
MODELS STILL IN GOOD AGREEMENT DURING THIS WEEK AND CONTINUE TO
SHOW A COLD FRONT MOVING INTO NORTHEAST MONTANA FROM THE
NORTHWEST ON THURSDAY COOLING THINGS OFF. THE SLIGHTLY COLDER
TEMPERATURES WILL LAST INTO SATURDAY BEFORE WARMING UP AHEAD OF
THE NEXT SYSTEM. SPEAKING OF THE NEXT SYSTEM...IT WILL ARRIVE
SATURDAY NIGHT INTO SUNDAY. A LARGE UPPER TROUGH OVER THE GREAT
BASIN WILL EJECT A SHORTWAVE TROUGH TO THE NORTHEAST. THIS
SHORTWAVE WILL ALLOW A SURFACE LOW TO DEVELOP AHEAD OF IT AS IT
TRACKS TOWARDS MONTANA.

THERE ARE DIFFERENCES IN THE LATEST ECMWF AND GFS ON WHERE THE
SURFACE LOW WILL TRACK. GFS TAKES THE SURFACE LOW INTO WESTERN
NORTH DAKOTA AND KEEPS NEMONT IN THE WRAP AROUND PRECIPITATION.
THE PRECIPITATION SHOULD FALL AS A RAIN SNOW MIX TO BEGIN WITH
BEFORE CHANGING OVER TO ALL SNOWFALL DUE TO 850 MB TEMPERATURES
DROPPING FROM AROUND 0 TO -5*C. THE ECWMF TAKES THE SURFACE LOW
THROUGH EASTERN MONTANA AND DRY SLOTS THE EASTERN PART OF THE CWA.
THE WESTERN PORTION OF THE CWA WOULD GET WRAP AROUND PRECIPITATION
IN THE FORM OF A RAIN SNOW MIX BEFORE THE PRECIPITATION CHANGES
OVER TO SNOW. THE STORM SYSTEM SHOULD LIFT OUT OF THE AREA BY
MONDAY AFTERNOON. RSMITH

PREVIOUS DISCUSSION...MODELS ARE IN BETTER AGREEMENT WITH
SOMEWHAT COLDER TEMPERATURES FOR THURSDAY WITH A SHORTWAVE UPPER
TROUGH MOVING THROUGH THE AREA. THE COLDER TEMPERATURES LINGER
INTO FRIDAY ALTHOUGH THE TROUGH MOVES TO THE EAST. WITH NIGHT TIME
TEMPERATURES EXPECTED TO BE BELOW FREEZING...SNOW MELT WILL SLOW
DOWN.

DEEP UPPER TROUGH MOVES INLAND FOR THE WEEKEND WITH A SURFACE LOW
DEVELOPING OFF THE LEE OF THE ROCKIES. MODELS DIFFER ON WHERE TO
DEVELOP THE SURFACE LOW. THEY DO AGREE ON BRING A DECENT SHORTWAVE
ACROSS EASTERN MONTANA SATURDAY NIGHT AND SUNDAY. AT THIS
POINT...IT LOOKS LIKE THE BEST CHANCE OF PRECIP WILL BE SATURDAY
NIGHT AND SUNDAY WITH TEMPERATURES COLD ENOUGH FOR SNOW. THE
SYSTEM LIFTS TO THE NORTHEAST EARLY NEXT WEEK. FORRESTER

.AVIATION...
PATCHES OF FOG ARE POSSIBLE LATE TONIGHT AND TUE MORN IN THE LOWER
MILK AND LOWER MISSOURI RIVER VALLEYS...INCLUDING TAF SITES GGW
AND OLF. THE FOG COULD REDUCE VISIBILITIES AS LOW AS 1 MILE AT
TIMES. OTHERWISE...VFR UNDER MOSTLY CLEAR SKIES. SIMONSEN

&&

.HYDROLOGY...
THE MUSSELSHELL RIVER BASIN... A FLOOD WARNING CONTINUES FOR
WESTERN GARFIELD AND PETROLEUM COUNTIES BASED ON REPORTS OF
MULTIPLE ICE JAMS THAT CONTINUE ON THE MUSSELSHELL RIVER AND
SURROUNDING CREEKS. WATER IN SOME CREEKS AND STREAMS CONTINUES TO
RUN BANK FULL WHILE IN OTHERS ARE SPILLING WELL OUT OF THEIR
BANKS. SOME NEARBY RANCHES ARE ALREADY BEING AFFECTED AS CALF
CREEK HAS SWOLLEN ALONG ITS BANKS AND IS CUTTING OFF OLD STAGE
ROAD NORTH OF HIGHWAY 200 ON THE GARFIELD COUNTY SIDE OF THE
MUSSELSHELL RIVER. FLOODING NORTH AND SOUTH OF HIGHWAY 200 IN THE
PETROLEUM COUNTY ALONG THE MUSSELSHELL HAVE ALSO BEEN REPORTED WITH
MOSTLY LOW LAND HAY FIELDS AND A FEW BARNS IMPACTED. LOCAL
DRAINAGES ARE SEEING PROBLEMS WITH FROZEN CULVERTS AND BLOCKED
FLOW FROM THE HIGH AMOUNTS OF SNOW AND ICE. EXPECT WARMER
TEMPERATURES TO CONTINUE TO MELT THE REMAINING SNOW WHICH WILL
PROLONG THE FLOODING ISSUES.

YELLOWSTONE RIVER BASIN... RIVER ICE HAS BEGUN TO BREAK UP ALONG
THE PRAIRIE AND DAWSON COUNTY SECTIONS OF THE YELLOWSTONE RIVER. AS
OF NOON THE MAIN AREAS OF FOCUS ARE NEAR GLENDIVE WHERE ICE HAS
BROKEN FREE FROM THE BELL STREET BRIDGE AND FLOWED TO A NEW ICE
JAM ALONG THE I-94 BRIDGE CAUSING MINOR FLOODING... AND 3 MILES
EAST OF TERRY WHERE AN ICE BLOCKAGE HAS BACKED UP ALL THE WAY TO
THE MOUTH OF THE POWDER RIVER. THESE ICE JAMS AT BOTH POINTS HAVE
RAISED THE RIVER SEVERAL FEET ABOVE NORMAL BUT ARE NOT IMPACTING
ANYTHING AS OF NOON. AS OF NOON RICHLAND COUNTY PORTION OF THE
YELLOWSTONE RIVER HAS NOT YET BROKEN UP OR FORMED ANY KNOWN JAMS.
SMALL STREAMS AND CREEKS THAT FLOW INTO THE YELLOWSTONE WILL
CONTINUE TO RUN HIGH DUE TO THE SNOW MELT...WHICH WILL ADD TO
FLOODING CONCERNS. THERE IS STILL PLENTY OF SNOW COVER TO MELT
THIS WEEK WHICH COULD LEAD TO CONTINUING PROBLEMS IN THE DRAINAGE
SYSTEM OF THE YELLOWSTONE.

MILK/MISSOURI RIVER BASIN... MAJORITY OF THE MILK RIVER TRIBUTARIES
ARE STILL FROZEN OR JUST BEGINNING TO THAW AS TEMPERATURES WARM
WELL ABOVE NORMAL. THERE IS STILL A FAIR AMOUNT OF FROZEN WATER
LOCKED UP IN THE HILLS AND FLATS. REPORTS FROM SOUTHWEST VALLEY
COUNTY HAVE SOME OF THE CREEKS ALREADY UP NEARING BANK FULL WITH
STILL PLENTY OF SNOW IN THE HILLS WAITING TO MELT. THE WARM UP
SHOULD BRING SOME RIVER GAUGE LEVELS UP AND MAY NEED SOME HYDRO
STATEMENTS ON RIVER RISES. GAH
