AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
307 AM MST THU JAN 3 2008

.DISCUSSION...

TODAY THROUGH SATURDAY...THE HIGH PRESSURE RIDGE HAS MOVED OVER THE
MIDWEST AND THE NEXT WEATHER SYSTEM...A LOW PRESSURE TROF OVER THE
EASTERN PACIFIC...IS APPROACHING THE WEST COAST. SOUTHWEST FLOW WILL
CONTINUE ALOFT AND SATELLITE INDICATES NUMEROUS WEAK DISTURBANCES
MOVING THROUGH THE FLOW. BY THURSDAY NIGHT...A FAST-MOVING SHORTWAVE
CROSSES THE WESTERN US AND APPROACHES THE ROCKIES. WINDS WILL KICK
UP AGAIN...AND WILL ISSUE ANOTHER HIGH WIND WARNING FOR THE NORTHERN
ROCKIES TO ACCOUNT FOR THE SHORTWAVE PASSAGE. BY FRIDAY...A DEEP LOW
PRESSURE SYSTEM MOVES OVER THE WEST COAST...AHEAD OF THIS
SYSTEM...WIDESPREAD LIFT WILL DEVELOP ACROSS THE ROCKIES AND SPREAD
EAST DURING THE DAY. THE EXTREME SOUTHERN PORTIONS OF THE CWA BECOME
SATURATED BY LATE AFTERNOON. WE WILL ALSO SEE STRONG SOUTHWEST FLOW
ALOFT DEVELOP...AND WILL ISSUE A WINTER STORM WATCH FOR THIS AREA.
WILL STRESS HIGHER ELEVATIONS ALONG WITH BLOWING SNOW AND RESTRICTED
VISIBILITIES. FIRST GUESS OF SNOW WOULD BE 4-8 INCHES...10 TO 20
ABOVE 7000 FEET WITH MOST OF THE SNOW OCCURRING TO THE SOUTH. BY
SATURDAY MORNING...MOST OF THE LIFT HAS MOVED EAST AND SNOW WILL
TAPER OFF...AND DO NOT ANTICIPATE SIGNIFICANT ACCUMULATIONS. ZELZER

SATURDAY NIGHT THROUGH TUESDAY NIGHT...THIS FORECAST PERIOD WILL BE
CHARACTERIZED BY TEMPERATURES BEGINNING ABOVE THE SEASONAL
AVERAGE...MODERATING DURING SUNDAY WITH A SUBTLE LARGE SCALE PATTERN
CHANGE OVER THE WESTERN CONUS. IT APPEARS THAT THERE HAS BEEN A
SLIGHT CHANGE IN THE FORECAST UPPER LEVEL PATTERN DURING THE
EXTENDED FORECAST PERIOD IN THE PAST 24 HOURS. ONE NOTABLE
DIFFERENCE BETWEEN PREVIOUS AND CURRENT GUIDANCE IS THE LACK IN THE
INITIAL AMPLITUDE OF THE SOUTHWESTERLY FLOW ALOFT...PRESENT OVER THE
FORECAST AREA DURING SATURDAY NIGHT. THIS FLOW ALOFT IS GENERALLY
ASSOCIATED WITH ABOVE AVERAGE TEMPERATURES...HOWEVER THIS AFFECT IS
DIMINISHED SOMEWHAT WITH A LOWER AMPLITUDE UPPER LEVEL TROUGH OF LOW
PRESSURE JUST OF THE WEST COAST. THIS TROUGH WILL AMPLIFY DURING
SUNDAY AS IT PROGRESSES OVER THE GREAT BASIN. THE MOST SIGNIFICANT
FORCING ASSOCIATED WITH THIS TROUGH WILL BE FAR SOUTH OF THE
FORECAST AREA...HOWEVER THE PASSAGE OF A WEAK TROUGH OVER THE
FORECAST AREA DURING SUNDAY WILL ALLOW FOR COOLER TO AIR MIX DOWN TO
THE SURFACE BY SUNDAY EVENING. A DISTURBED WEST TO EAST FLOW ALOFT
BECOMES DOMINANT OVER THE FORECAST AREA MONDAY AND TUESDAY...WITH A
CLOSED AREA OF LOW PRESSURE DEVELOPING ON THE EASTERN SLOPE OF THE
ALBERTA ROCKIES TUESDAY EVENING...AND MOVING SOUTH INTO THE FORECAST
AREA OVERNIGHT TUESDAY. THIS LOW WILL LIKELY BRING COLDER AIR INTO
THE NORTH CENTRAL PLAINS...HOWEVER IT IS UNCLEAR IF THE DEPTH OF
THIS COLD AIR WILL BE SUFFICIENT TO INFILTRATE THE SOUTHWEST
VALLEYS. ZUMPFE

WEDNESDAY AND THURSDAY...MODELS NOT IN VERY GOOD AGREEMENT ON
THURSDAY. WILL GO WITH GFS MODEL. GFS HAS AN UPPER LEVEL LOW OVER
THE AREA WITH MOST DYNAMICS REMAINING SOUTH OF MONTANA. THUS...WILL
GO WITH NEAR SEASONAL TEMPERATURES WITH AT LEAST A SLIGHT CHANCE OF
SNOW BOTH DAYS. WILLIAMSON DC

.AVIATION...
UPDATED 0529Z.
MAINLY VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH 06Z ON FRIDAY
ACROSS THE REGION...AS AN UPPER LEVEL RIDGE SLIDES EASTWARD. MAIN
CONCERN THROUGH 06Z FRIDAY WILL BE THE WINDS. AT KCTB...KGTF...AND
KLWT...WINDS HAVE DIMINISHED QUITE A BIT...BUT OCCASIONAL 20 TO 30
KT GUSTS WILL STILL BE POSSIBLE DUE TO STRONG WINDS ALOFT. AFTER 18Z
THURSDAY...WINDS ALOFT INCREASE...AND MORE FREQUENT GUSTS BETWEEN 20
TO 30 KTS ARE EXPECTED AT KCTB...KGTF...AND KLWT. AT
KBZN...KHLN...AND KHVR...WINDS WILL BE LIGHTER. ADDITIONALLY...WITH
MOISTURE MOVING THROUGH THE FLOW ALOFT...HIGH CLOUDS ARE EXPECTED
ACROSS THE ENTIRE AREA...WITH CEILINGS GENERALLY AT OR ABOVE 12000
FEET. HOWEVER...CEILINGS DOWN TO 7000 FEET MAY OCCUR AROUND KCTB
BETWEEN 10Z AND 18Z THURSDAY. ALSO...SCATTERED SNOW SHOWERS WILL BE
POSSIBLE OVER THE NORTHERN ROCKY MOUNTAIN FRONT AFTER 10Z
THURSDAY...WHICH COULD LEAD TO MOUNTAIN OBSCURATIONS. COHEN
