AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
910 PM MDT TUE APR 27 2010

...WINDY WEATHER IN STORE FOR NORTHEAST MONTANA...

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH THURSDAY...
EVENING UPDATE...VERY DRY SOUNDING IN KGGW THIS EVENING WITH A
STRONG INVERTED V. LOTS OF RADAR RETURNS BUT LOOKING OUTSIDE IT'S
ALL VIRGA. EVEN THE STRONGER RETURNS OVER CENTRAL MONTANA HAVE
ONLY PRODUCED A TRACE TO .01 AT KGTF THIS EVENING. PRETTY COMPLEX
FORECAST COMING UP WITH THE LOW PRESSURE SYSTEM DEEPENING OVER SW
MT AT THE MOMENT. THE SYSTEM IS FORECAST TO MOVE SLOWLY NORTHWARD
OVER THE NEXT 24 HOURS CENTERING OVER SOUTHERN SASKATCHEWAN BY
TOMORROW NIGHT. MODELS ARE INCONSISTENT WITH PRECIPITATION
POTENTIAL. 18Z MODELS WERE PRETTY GENEROUS WITH AMOUNTS AND AREAL
COVERAGE STARTING TOMORROW MORNING BUT THE 00Z NAM CAME IN MUCH
DRIER PUTTING MOST OF OUR CWA IN A DRY SLOT EXPECT FOR THE EXTREME
WESTERN COUNTIES OF PHILLIPS AND PETROLEUM.

MAIN FORECAST ISSUE TONIGHT IS THE POSSIBILITY OF RED FLAG
CONDITIONS FOR A FEW HOURS WEDNESDAY AFTERNOON IN THE TWO WESTERN
FIRE WEATHER ZONES. THEY WILL HAVE A PERIOD WHERE THE SOUTHEAST
WINDS ABRUPTLY SWITCH TO THE WEST AND INCREASE INTO THE 20 TO 35
MPH RANGE WITH GUSTS TO 45 MPH POSSIBLE. 18Z GFS AND NAM GIVES
.25" OF PRECIP ACROSS SOME OF THE EASTERN ZONES WHICH WOULD ALLEVIATE
ANY FIRE CONCERNS IF IT REALLY HAPPENS. BUT THE 00Z NAM THAT IS
JUST COMING IN REALLY BACKS OFF ON US GETTING ANY MOISTURE IN THE
EAST. THE WESTERN ZONES WILL NOT SEE THE PRECIPITATION ASSOCIATED
WITH THE COLD FRONT UNTIL AFTER 4 OR 5 PM AND WHILE THE RH'S WILL
BE IN THE 20-30 PERCENT RANGE...WE STILL HAVE NOT HIT FULL GREENUP
AND WINDS OF THIS INTENSITY WILL CAUSE PROBLEMS WITH ANY FIRE
STARTS. FRANSEN

PREVIOUS DISCUSSION...AN APPROACHING PACIFIC STORM SYSTEM IS EFFECTIVELY
BREAKING DOWN THE SHORTWAVE RIDGE THAT DOMINATED TODAY. WEAK ECHOS
CONTINUE TO PUSH IN AHEAD OF THE STORM...BUT GIVEN VERY DRY LOW
LEVELS VIRGA IS ALL THAT IS EXPECTED THIS EVENING. THE EXCEPTION
TO THIS COULD BE THE LITTLE ROCKIES WHERE SOME LIGHT PRECIP COULD
FALL A BIT LATER ON IN THE EVENING AS THINGS MOISTEN UP. SHOWERS
WILL SLOWLY BUILD INTO THE WESTERN HALF OF THE CWA AFTER MIDNIGHT
TONIGHT. WINDS WILL STAY UP TONIGHT AS THE GRADIENT REMAINS TIGHT.
TEMPERATURES WILL ALSO STAY ON THE WARM SIDE GIVEN SAID WINDS AND
INCREASING CLOUD COVER.

WEDNESDAY IS GOING TO BE WINDY. THE ASSOCIATED COLD FRONT WILL
BEGIN TO PUSH THROUGH WEDNESDAY MORNING...ALLOWING STRONG WESTERLY
WINDS TO DEVELOP IN ITS WAKE. GFS MODEL IS CONSIDERABLY STRONGER
THEN THE NAM AND ECMWF WITH WIND SPEEDS FOR WEDNESDAY AFTERNOON.
FELT CONFIDENT IN ISSUING A HIGH WIND WATCH FOR THE FAVORED AREA
OF SOUTHWEST PHILLIPS COUNTY. MUCH OF THE REMAINDER OF THE AREA
WILL NEED TO BE WATCHED HOWEVER AS WINDS COULD CREEP UP TO WARNING
CRITERIA. A DRY SLOT CONTINUES TO LOOK LIKE A MAJOR PLAYER WITH
THIS DEVELOPING STORM...THUS CONTINUED TO BE CONSERVATIVE ON THE
POP FORECAST...ESPECIALLY ACROSS THE EAST. THAT BEING SAID WRAPAROUND
PRECIP LOOKS TO BE MORE PRODUCTIVE WITH THIS SYSTEM...AND IT LOOKS
TO MAKE ITS WAY INTO PHILLIPS COUNTY BY THE AFTERNOON.

WEDNESDAY NIGHT INTO THURSDAY WRAPAROUND PRECIPITATION LOOKS TO BE
THE BIGGEST PLAYER...ACROSS THE WESTERN HALF OF THE FORECAST AREA.
ALTHOUGH THERE IS NOW DECENT MODEL CONSISTENCY WITH THIS
SYSTEM...CONTINUED TO BE CONSERVATIVE REGARDING THE POP FORECAST
AS THE EXACT PLACEMENT OF THE LOW WILL MAKE OR BREAK THE FORECAST.
SNOW LEVELS BEGIN TO LOWER AS WELL BY THURSDAY AS COLDER AIR IS
PUSHED SOUTHWARD BY THE STRONG LOW. WENT AHEAD AND ADDED SNOW
ABOVE 4K FEET IN THE LITTLE ROCKIES FOR THURSDAY AFTERNOON. WINDY
CONDITIONS WILL CONTINUE THROUGH THURSDAY AS THE SURFACE GRADIENT
REMAINS TIGHT. GIVEN HIGH CONFIDENCE IN WINDY CONDITIONS...EXTENDED
THE CURRENT LAKE WIND ADVISORY THROUGH THURSDAY EVENING. GILCHRIST

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...
THE EXTENDED PERIOD BEGINS THURSDAY NIGHT WITH A UPPER LEVEL LONG-
WAVE TROUGH COVERING THE WESTERN HALF OF CONUS...WITH AN EMBEDDED
CLOSED LOW CENTER SPINNING OVER THE LOCAL CWA. MODELS SHOW THE
VERY BEGINNINGS OF THE ASSOCIATED SURFACE LOW CLOSING
OFF...TRENDING TOWARDS THE CYCLONIC SYSTEM STARTING TO STACK UP.
UPPER WINDS BEGIN TO LINE UP AT ALL LEVELS...SOME OF WHICH WILL
MIX TO THE SURFACE FOR RAPIDLY CHANGING WIND DIRECTION AS THE LOW
CENTER MOVES ACROSS THE AREA THURSDAY NIGHT AND FRIDAY. MODELS ARE
HAVING DIFFICULTY DETERMINING AREAS OF PRECIPITATION WITH WRAP-
AROUND DRY SLOTTING IN THE MIX. SO WILL CONTINUE WITH BROAD-BRUSH
HIGH CHANCE POPS THROUGH FRIDAY. THE 12Z EC CAME IN SUPPORTING THE
12Z GFS FOR A WET THURSDAY NIGHT AND FRIDAY. INCREASED POPS TO
LIKELY IN CONJUNCTION WITH NEIGHBORS.

FRIDAY NIGHT THROUGH SATURDAY NIGHT...THE LOW CENTER MOVES EAST OF
THE LOCAL AREA AND STRENGTHENS PRODUCING SOME WRAP-AROUND CHANCE
PRECIPITATION AND STRONG NORTHWEST WINDS OVER NEMONT. DRY SLOTTING
COULD BE MORE INFLUENTIAL IN INTERFERING WITH QPF AMOUNTS DURING
THIS PERIOD. AGAIN ADJUSTED POPS UPWARD WITH REGIONAL TREND.

SUNDAY AND BEYOND...MODELS CONTINUE TO HAVE PROBLEMS WITH CONDITIONS
BEHIND THIS STORM SYSTEM. THE EC MOVES THE TROUGH EAST AND
INTRODUCES ZONAL FLOW ALOFT...FOLLOWED BY ANOTHER TROUGH...WHILE
THE GFS BUILDS A RIDGE OVER THE WEST COAST AND KEEPS THE LOCAL
AREA WITHIN THE TROUGH. IN EITHER CASE..THE CHANCES FOR SHOWERS
REMAIN...BUT MUCH DIMINISHED. HOWEVER CONFIDENCE IS VERY LOW SO
DID NOT ADJUST POPS FOR THIS PERIOD. SCT

PREVIOUS DISCUSSION...
THE GFS...ECMWF AND GEM BEGIN THE EXTENDED PERIOD THURSDAY EVENING
IN AGREEMENT WITH A LONG-WAVE TROF SPREAD OVER THE WESTERN HALF
OF US. THIS HAS BEEN THE TREND FOR THE LAST SEVERAL MODEL RUNS
WHICH CONTINUES TO BE THE CASE. SO THE EXTENDED PERIOD WILL
PROVIDE NEMONT WITH A CHANCE OF PRECIPITATION EACH DAY.

ALONG WITH THE UPPER TROF A STACKED CLOSED LOW SYSTEM OVER THE
SOUTHERN SASKATCHEWAN...NORTHEASTERN MONTANA AND NORTHWEST NORTH
DAKOTA. THE MODELS DO VERY SOMEWHAT ON THE EXACT PLACEMENT OF THIS
SYSTEM BUT THEY ALL HAVE IT LOCATED IN THE REGION DESCRIBED ABOVE.
THIS THING WILL SIT AND SPIN OVER THE NORTHERN PLAINS AND IT WILL
BE THE MAIN WEATHER PLAYER FOR THE REST OF THE EXTEND PERIOD. SO
CONTINUED THE TREND OF INCREASING POPS WHERE MODEL CONFIDENCE
INCREASES...MATCHING UPDATES FROM SURROUNDING OFFICES.
TEMPERATURES LOOKS FINE SO FEW CHANGES THERE BUT MAY NEED TO BE
COOLED SLIGHTLY ON SATURDAY AS THE GFS IS HINTING AT UP ON SOME
STRONG CAA SHOWING UP FRIDAY AFTERNOON INTO SATURDAY.

SPEAKING OF FRIDAY AFTERNOON THINGS START TO GET INTERESTING.
FRIDAY AFTERNOON A SURFACE HIGH WILL SLIDE SOUTHWARD ACROSS
WESTERN MONTANA AND THAT WILL INCREASE THE PRESSURE GRADIENT WITH
THIS STACKED SYSTEM AT THE SURFACE. THE LATEST GFS IS SHOWING 850
MB WINDS SPEED BETWEEN 40 AND 50 KNOTS SLIDING ACROSS THE WESTERN
ZONES. WITH THE STACKED SYSTEM TO THE EAST...EXPECT THE WINDS TO
HAVE LITTLE PROBLEM MIXING TO THE SURFACE.

AT THIS POINT THE GFS IS SHOWING 40 TO 50 KNOTS WIND SPEEDS OUT OF
THE NORTHWEST ACROSS MOST OF THE CWA AT 850 MB. THE ADJDGX AND
ADJMEX MODEL GRIDS ARE SHOWING SURFACE WIND SPEEDS BETWEEN 30 AND
37 KNOTS WHICH WOULD RESULT IN SURFACE WIND SPEEDS BETWEEN 35 AND
43 MPH. THIS IS WELL WITH IN THE HIGH WIND WATCH CRITERIA. SO ONE
MIGHT BE NEEDED FOR FRIDAY AFTERNOON THROUGH SATURDAY MORNING. I
PUT THIS INFORMATION INTO THE HWO AND WILL LET THE DAY SHIFT TAKE
A LOOK AT THIS TO SEE IF THE 12Z GFS STAYS LIKE THIS. NEEDLESS TO
SAY IF THIS TREND CONTINUES A HIGH WIND WATCH WILL BE NEEDED.

DUE TO THE CAA ON THE GFS AND 850 MB TEMPERATURES BETWEEN 0*C AND
-3*C...ANY PRECIPITATION THAT DOES FALL ACROSS NEMONT FRIDAY
THROUGH SATURDAY MORNING WILL CHANGE FROM RAIN TO A RAIN SNOW MIX
AS THE COLD AIR SINKS INTO SOUTHERN MONTANA...AND THEN MAYBE TO
ALL SNOW ACROSS NEMONT. THE GFS THEN SHOWS THE PRECIPITATION MOST
OF THE WEEKEND AS SNOW. HOWEVER SINCE THE OTHER MODELS ARE NOT
THAT COLD YET KEPT THINGS AS A COLD RAIN SATURDAY AFTERNOON AND
SUNDAY AFTERNOON. MORE OF A RAIN SNOW MIX SATURDAY NIGHT AND
SUNDAY NIGHT. THE UPPER TROF WILL BEGIN TO BREAK DOWN ON MONDAY
BUT THE CHANCE OF PRECIPITATION SHOULD LAST INTO TUESDAY. RSMITH

&&

.AVIATION...
AN UPPER LEVEL RIDGE PASSING OVER THE LOCAL REGION WILL MAINTAIN
VFR CONDITIONS THROUGH TONIGHT. A SURFACE HIGH PRESSURE AREA OVER
NORTH DAKOTA WILL CONTINUE THE STRONG EASTERLY TO SOUTHEASTERLY
WINDS TONIGHT AROUND KGGW. WINDS ELSEWHERE WILL WEAKEN OVERNIGHT
TO AROUND 10-15KTS. HIGH CLOUDS WILL GIVE WAY TO MID LEVEL
TONIGHT.

WEDNESDAY A COLD FRONT TRAVELING EAST THROUGH THE REGION WILL
SHIFT WINDS AROUND TO THE NORTHWEST AND BRING A INCREASING CHANCE
FOR RAIN SHOWERS. WIND STRENGTH WILL RAMP UP AGAIN DURING THE DAY
TO 15-25 KTS. SCT

&&

.FIRE WEATHER...
WEDNESDAY MORNING WILL BRING AN ABRUPT WIND SHIFT TO THE WEST AS
A POTENT COLD FRONT PUSHES THROUGH. ALTHOUGH HUMIDITY WILL REMAIN
AT 25 TO 35 PERCENT...STRONG TO VERY STRONG WEST WINDS COULD MAKE
FOR ANOTHER ROUND OF CRITICAL FIRE WEATHER CONDITIONS INTO
WEDNESDAY EVENING ACROSS ALL OF NORTHEAST MONTANA. GILCHRIST

&&

.GLASGOW WATCHES/WARNINGS/ADVISORIES...
HIGH WIND WATCH FROM WEDNESDAY AFTERNOON THROUGH WEDNESDAY
EVENING FOR SOUTHWEST PHILLIPS.

LAKE WIND ADVISORY UNTIL 9 PM MDT THURSDAY FOR FORT PECK LAKE.

GUSTY SOUTHEAST WINDS WILL CONTINUE OVERNIGHT. A LAKE WIND
ADVISORY IS IN EFFECT ACROSS THE WATERS OF FORT PECK LAKE FOR 15
TO 25 MPH SOUTHEAST WINDS THROUGH THE MORNING.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

AN ABRUPT WIND SHIFT TO WESTERLY WINDS CAN BE EXPECTED WEDNESDAY
AS A COLD FRONT PUSHES EASTWARD ACROSS MONTANA. GUSTY WESTERLY
WINDS AT 25 TO 40 MPH...WITH GUSTS APPROACHING 50 MPH CAN BE
EXPECTED ACROSS MUCH OF THE AREA. IMPACTS FROM THESE WINDS WILL BE
FELT ALONG NORTH TO SOUTH ROADS...THIS IS ESPECIALLY TRUE FOR HIGH
PROFILE VEHICLES. ALSO...NON SECURED ITEMS AROUND THE EXTERIOR OF
YOUR HOUSE MAY BLOW AWAY IN THE WINDS.

WINDS COULD BE ESPECIALLY STRONG NEAR THE LITTLE ROCKIES IN
SOUTHWEST PHILLIPS COUNTY STARTING AROUND MIDDAY WEDNESDAY. WEST WINDS
COULD BE SUSTAINED AT 40 MPH...WITH GUSTS APPROACHING 60 MPH THERE.
A HIGH WINDS WATCH IS IN EFFECT FOR SOUTHWEST PHILLIPS
COUNTY...INCLUDING THE LITTLE ROCKIES.

THE STRONG LOW PRESSURE SYSTEM WILL CONTINUE TO MOVE OVER EASTERN
MONTANA AND WESTERN NORTH DAKOTA FRIDAY AND SATURDAY DRIVING
