AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
940 AM MST FRI JAN 4 2008

.UPDATE...AN EXTREMELY UNUSUAL WEATHER PATTERN IS IN PLACE ACROSS
MY FORECAST AREA TODAY AND TONIGHT. BIGGEST PROBLEM IS A STRONG
LOW AND MID LEVEL JET STREAK THAT MOVES ACROSS SOUTHWEST AND
CENTRAL MONTANA DURING THIS PERIOD. ALL INDICATIONS ARE THAT WINDS
OF ANYWHERE FROM 50 TO 70 KNOTS WILL MIX TO THE SURFACE...
ESPECIALLY ON THE NORTH AND NORTHEAST SIDE OF MOUNTAIN RANGES.
WILL ISSUE A HIGH WIND WARNING FOR ALL OF SOUTHWEST MONTANA AND
PORTIONS OF CENTRAL MONTANA. WINTER STORM WARNINGS THAT ARE ALREADY
IN PLACE AND SET TO BEGIN AT MID-AFTERNOON STILL LOOK GOOD AND
WILL REMAIN IN EFFECT. CLOUD COVER AND PRECIPITATION HAVE BEEN
DELAYED A BIT THIS MORNING AS THE SYSTEM ALONG THE COAST HAS BEEN
SLOWER TO MOVE INLAND THAN ORIGINALLY PROGGED. HAVE LOWERED POPS
AND SKY CONDITION TO ACCOUNT FOR THIS...BUT THINGS STILL LOOK GOOD
FOR CLOUDS AND PRECIPITATION TO MOVE IN THIS AFTERNOON. MORNING
SUN AND DOWNSLOPE WINDS ARE ALSO AFFECTING TEMPERATURES SO HAVE
TWEAKED TODAYS HIGHS UP A BIT IN SEVERAL LOCATIONS. MPJ

&&

.AVIATION...
A VIGOROUS UPPER LEVEL TROUGH MOVES ONSHORE IN THE PACIFIC NW
TODAY WITH A STRONG MID TO UPPER LEVEL JET STREAM ROTATING
THROUGH THE BASE OF OF THE TROUGH AND UP THROUGH WESTERN AND
CENTRAL MT THIS AFTERNOON AND EVENING. PRECIPITATION WILL MAINLY
BE CONFINED TO THE MTNS THROUGH THE PERIOD...WHERE LOCAL MVFR TO
OCCASIONAL IFR CONDITIONS IN SNOW WILL INCREASE LATER THIS
AFTERNOON AND EVENING AS MOISTURE ASSOCIATED WITH THE SYSTEM MOVES
INLAND. OVER THE PLAINS AND VALLEYS VFR CONDITIONS WILL GENERALLY
PREVAIL THROUGH THE NEXT 24 HRS. MAIN IMPACT TO AVIATION AT ALL
TERMINALS WILL BE INCREASING WINDS AS THE UPPER LEVEL JET MOVES
OVER THE REGION THIS AFTERNOON AND EVENING. WINDS IN EXCESS OF
60KTS ARE LIKELY ACROSS RIDGETOPS OF MOST OF CENTRAL AND SOUTHWEST
MT. OCCASIONAL GUSTS IN EXCESS OF 50KTS WILL BE POSSIBLE AT TIMES
IN SOME OF THE SW MT VALLEYS AND ACROSS PORTIONS OF CENTRAL
MT...POSSIBLY IMPACTING THE KGTF AND KLWT TERMINALS. TIMING OF
STRONGEST WINDS SHOULD BE BETWEEN 22Z AND 06Z WITH WINDS GRADUALLY
DIMINISHING THEREAFTER. HOENISCH

.PREV DISCUSSION... (ISSUED 432 AM MST FRI JAN 4 2008)

DISCUSSION...
ANOTHER VERY INTERESTING WEATHER DAY FOR THE AREA. WINDS HAVE KEPT
TEMPERATURES RATHER WARM OVERNIGHT SO TEMPERATURES HAVE A GOOD
START TO BE ABOVE NORMAL AGAIN TODAY. GUSTY WINDS OVER MOST OF THE
AREA WILL ALSO HELP KEEP TEMPERATURES WARM. HAVE NEAR RECORD HIGH
TEMPERATURES FORECAST FOR PORTIONS OF BEAVERHEAD AND MADISON
COUNTIES INCLUDING THE CITY OF DILLON. STRONG PACIFIC STORM SYSTEM
IS STILL FORECAST TO MOVE TOWARDS THE AREA THIS AFTERNOON AND
TONIGHT. PRECIPITATION WILL BE RESTRICTED MAINLY TO THE WESTERN
AND SOUTHWESTERN MOUNTAINS DUE TO THE VERY STRONG WINDS OVER MOST
OF THE AREA. WINTER STORM WARNING FOR THE SOUTHERN PORTIONS OF
SOUTHWEST MONTANA WILL BE CONTINUED. HAVE CANCELLED HIGH WIND
WATCH FOR THE NORTHERN ROCKY FRONT AND HAVE ISSUED A WINTER STORM
WARNING FOR SNOW AND WINDS ABOVE 5000 FEET. MODELS BEGIN TO BRING
COOLER AIR TO THE AREA SATURDAY BUT WINDS CONTINUE TO BE STRONG
SO HAVE GONE ABOVE GUIDANCE FOR TEMPERATURES. WINDS BEGIN TO
DECREASE SATURDAY NIGHT AND SUNDAY AND HAVE LOWERED TEMPERATURES
CLOSER TO NEAR NORMAL. SEVERAL DISTURBANCES IN UPPER LEVEL FLOW TO
KEEP CHANCE OF PRECIPITATION OVER THE WESTERN AND SOUTHWESTERN
MOUNTAINS. CAMP

SUNDAY NIGHT THROUGH WEDNESDAY NIGHT...A PROGRESSIVE UPPER LEVEL
PATTERN WILL CONTINUE THROUGH THE EXTENDED FORECAST PERIOD. MODELS
ARE IN GENERAL AGREEMENT ON A BROAD TROUGH OVER THE REGION SUNDAY
NIGHT THOUGH MONDAY...FOLLOWED BY WEAK RIDGING FOR THE MONDAY NIGHT
THROUGH TUESDAY PERIOD WITH A RETURN TO BROAD TROUGHING OVER THE
REGION TUESDAY NIGHT THOUGH THURSDAY NIGHT. CONFIDENCE IN DETAILS OF
SPECIFIC SYSTEMS EMBEDDED WITHIN THE FLOW ALOFT IS MUCH LOWER THAN
FOR THE OVERALL PATTERN...ESPECIALLY LATER IN THE PERIOD...AS MEDIUM
RANGE MODELS DIFFER WITH TIMING AND STRENGTH OF THESE FEATURES...AS
IS USUALLY THE CASE IN FAST WESTERLY FLOW PATTERNS. HAVE GENERALLY
MAINTAINED A BROADBRUSH APPROACH TO POPS THROUGH THE PERIOD WITH A
CHANCE OF SNOW OVER THE WESTERN AND SOUTHWEST MTNS THROUGH MUCH OF
THE PERIOD IN A MOIST AND AT TIMES UNSTABLE WESTERLY FLOW ALOFT.
POPS THEN TREND CLOSER TO CLIMO FROM TUESDAY NIGHT THROUGH WEDNESDAY
NIGHT AS ADDITIONAL ENERGY MOVES THROUGH THE FLOW WITH A BROAD
TROUGH TROUGH REDEVELOPING OVER THE REGION. TEMPERATURES WILL BE
NEAR SEASONAL AVERAGES THROUGH THE PERIOD. HOENISCH

THURSDAY AND FRIDAY...LATEST MODELS INDICATE AN UNSETTLED WEST TO
NORTHWEST FLOW THROUGH THE PERIOD. A CHANCE FOR SCATTERED SNOW
SHOWERS FOR THE MOUNTAINS AND A SLIGHT CHANCE FOR THE NORTH AND
CENTRAL PLAINS. TEMPERATURES ARE EXPECTED TO BE NEAR SEASONAL.
