AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
321 AM MST TUE NOV 13 2007

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH THURSDAY...
COLD FRONT IS CURRENTLY NEAR REGINA...SACO AND WINNETT. THIS
FRONT WILL BLOW THROUGH THE FORECAST AREA DURING THE NEXT FEW
HOURS WITH UPPER LEVEL SHORTWAVE PASSING THROUGH LATER THIS
MORNING. THE BEST COLD AIR ADVECTION...PRESSURE RISES AND WINDS
ALOFT WILL PASS THROUGH NORTHEAST MONTANA BY 15Z THIS MORNING.
THIS PUTS IT OUTSIDE THE FAVORABLE TIME OF DAY FOR HIGH WIND
WARNING CRITERIA WINDS. EXPECT THE WINDS TO BE NEAR WARNING
CRITERIA TODAY WITH 40 TO 45 KNOT 850 MB WINDS EXPECTED THIS
AFTERNOON BUT THE WINDS SHOULD FOR THE MOST PART STAY BELOW
WARNING CRITERIA OF 40 MPH FOR ONE HOUR AND GUSTS TO 58 MPH. MAY
SEE ISOLATED GUSTS TO 60 MPH IN SOME FAVORED LOCATIONS. WILL
CANCEL HIGH WIND WATCH. TEMPERATURES THAT ARE NEAR 60 AT 10Z WILL
FALL INTO THE 40S THIS MORNING WITH THE COLD AIR ADVECTION. THEY
SHOULD RISE BACK UP A FEW DEGREES WITH DAYTIME HEATING. MOISTURE
WITH THIS SYSTEM WILL STAY TO THE SOUTH OF THE FORECAST AREA FOR
THE MOST PART. WILL LIMIT SLIGHT CHANCE OF SHOWERS TO SOUTHERNMOST
AREAS THIS MORNING.

A SECONDARY COLD FRONT ON NORTHWEST FLOW ALOFT WILL DROP SOUTH
THROUGH NORTHEAST MONTANA THIS EVENING WHICH WILL KEEP THE
NORTHWEST WINDS GOING ALTHOUGH NOT AS STRONG AS DURING THE DAY.
TEMPERATURES WILL FALL INTO THE 20S ACROSS THE AREA FOR LOWS
TONIGHT.

HIGH PRESSURE WILL START BUILDING INTO MONTANA FROM THE WEST ON
WEDNESDAY BUT EXPECT NORTHWEST WINDS TO CONTINUE THROUGH THE DAY
WITH THE STRONGEST WINDS IN THE EAST. THE HIGH PRESSURE MOVES
THROUGH EASTERN MONTANA WEDNESDAY NIGHT ALLOWING THE WINDS TO
BECOME LIGHT.

UPPER RIDGE BUILDS INTO MONTANA ON THURSDAY BRINGING SOME WARMER
TEMPERATURES BACK INTO THE REGION. THE WARMING WILL BE FELT IN THE
WESTERN ZONES THE MOST SO WILL GO WARMER THERE THAN ANYWHERE ELSE
ON THURSDAY. FORRESTER

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...
THE PERIOD BEGINS SOMEWHAT AMPLIFIED WITH AN UPPER RIDGE OVER THE
INLAND WESTERN STATES FRI AND SAT...AND A STRONG CLOSED LOW OVER THE
GULF OF ALASKA. THEN THE UPPER LOW AND THE RIDGE WEAKEN. MODEL
CONSENSUS HAS A SHORTWAVE TROUGH MOVING ACROSS OUR AREA ABOUT SUN
AND SUN NIGHT. TIMING AND INTENSITY HAVE VARIED QUITE A BIT
BETWEEN THE MODELS AS WELL AS RUN TO RUN. 18Z GFS WAS MUCH
STRONGER THAN THE PREVIOUS RUN...00Z RUN IS NOT QUITE AS STRONG.
MEANWHILE THE 00S ECMWF WAS MUCH SLOWER. PREFER THE FASTER
MOVEMENT OF SYSTEMS LATELY...SO LATEST GFS IS REASONABLE. SURFACE
AND UPPER SUPPORT AS WELL AS APPEAR ENOUGH TO MERIT A COUPLE
PERIODS OF NEAR 20 POPS FOR THIS SYSTEM. ANYTHING WE GET FROM THIS
AGAIN WILL BE MAINLY LIGHT RAIN...BUT MAY END AS LIGHT SNOW SUNDAY
NIGHT.

OTHER WEAK SHORTWAVES DURING THE PERIOD WONT AMOUNT TO MUCH OTHER
THAN PERIODS OF CLOUDINESS...SO THE NET RESULT WILL BE SKIES
AVERAGING PARTLY CLOUDY MUCH OF THE TIME.

COOL FRONT WITH THE SUNDAY THEN IS FOLLOWED BY COOL ADVECTION IN
NW WINDS COOLING TEMPS OFF TO CLOSER TO NORMAL FOR MON AND TUE.
LAST 2 GFS RUNS LOOKED JUST A LITTLE TOO COOL FOR THE PATTERN
COMPARED TO PREVIOUS RUNS AND OTHER MODELS THOUGH. SIMONSEN

&&

.AVIATION...
VFR...BUT VERY WINDY TODAY. WEST WIND SHIFTING TO NW THIS
MORNING...AND INCREASING TO 30 TO 35 KT...WITH GUSTS UP TO 45 KT.
WINDS TO DIMINISH ON A LITTLE TONIGHT. CLOUD LAYERS WILL BE
SCATTERED TO BROKEN AT 10K FT AGL. SIMONSEN

&&

.FIRE WEATHER...
DOWNSLOPING WINDS HAVE MADE FOR A VERY DRY AIRMASS ACROSS THE
CENTRAL PART OF THE STATE...WITH DEWPOINTS IN THE SINGLE DIGITS TO
LOWER TEENS. THIS DRY AIRMASS WHEN COMBINED WITH STRONG WEST TO
SOUTHWEST WINDS HAS THE POTENTIAL TO MAKE FOR CRITICAL FIRE
WEATHER CONDITIONS INTO THIS AFTERNOON. GILCHRIST

&&

.CLIMATE...
