AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1040 PM MST MON JAN 24 2011

UPDATED AVIATION DISCUSSION

.UPDATE...
AREA OF LIGHT VALLEY RAIN AND MTN SNOW CONTINUES OVER PORTIONS OF
CENTRAL AND SOUTHWEST MONTANA.  BASED ON SURFACE OBSERVATIONS SNOW
LEVEL IS ABOUT 5000 FT OVER CENTRAL MT AND ABOUT 4000 FT OVER
SOUTHWEST MT.  PRECIPITATION IS DRIFTING SLOWLY TO EAST-SOUTHEAST
WITH ITS BACK END CURRENTLY ALONG LINE FROM CHOTEAU TO HELENA.
THUS EXPECT SEVERAL LOCATIONS WILL SEE DRY CONDITIONS FOR MUCH OF
THE OVERNIGHT PERIOD BEFORE NEXT PLUME OF MOISTURE ARRIVES TUES
MORNING IN CONJUNCTION WITH THE UPPER LOW PRESSURE AREA PRESENTLY IN
ERN WASHINGTON.  DID NOT MAKE ANY FURTHER GRID ADJUSTMENTS AFTER
INCREASING PRECIP AREA IN CENTRAL MT...GOING FORECAST IN GOOD SHAPE
AT THIS POINT.  WARANAUSKAS

.DISCUSSION...
TONIGHT THROUGH WEDNESDAY...A WEATHER DISTURBANCE ALOFT NEAR
THE CASCADES MONDAY AFTERNOON WILL DIVE SOUTHEAST MONDAY NIGHT
WITH THE NORTHERN PORTION CLIPPING SOUTHWEST MONTANA LATE TONIGHT
AND EARLY TUESDAY. ALTHOUGH THE AIRMASS WILL BE MOIST LIFT IS NOT
REAL IMPRESSIVE. WILL CONTINUE WITH THE IDEA OF LIGHT
PRECIPITATION AMOUNTS. PRECIPITATION SHOULD BE IN THE FORM OF SNOW
OVER SOUTHWEST MONTANA BUT THE EAST SLOPES OF THE ROCKY MOUNTAINS
ARE EXPECTED TO SEE A MIX OF SNOW AND RAIN WITH A RISK OF FREEZING
RAIN. PRECIPITATION AMOUNTS OVER THE EAST SLOPES SHOULD BE MINIMAL
SO AM NOT PLANNING ON ANY ADVISORIES. OVER NORTH CENTRAL MONTANA
EXPECT PRECIPITATION TONIGHT INTO TUESDAY WILL BE MAINLY IN THE
FORM OF SNOW. AS THE DISTURBANCE MENTIONED ABOVE MOVES SOUTHEAST
TUESDAY AN UPPER RIDGE WILL BE DEVELOPING OFF THE PACIFIC
NORTHWEST COAST AND OVER BRITISH COLUMBIA. THIS UPPER RIDGE WILL
MOVE EAST TUESDAY NIGHT WITH ANY LINGERING SNOW SHOWERS OVER THE
WESTERN MOUNTAINS ENDING BY EARLY WEDNESDAY MORNING. THE FORECAST
AREA WILL CONTINUE UNDER THE INFLUENCE OF THE UPPER RIDGE ON
WEDNESDAY FOR DRY WEATHER. AS FOR THE WIND SITUATION..WILL
CONTINUE WITH THE HIGH WIND WARNING FOR THE ROCKY MOUNTAIN FRONT
INTO EARLY MONDAY EVENING. WINDS SHOULD DIMINISH BY LATE MONDAY
EVENING. THEN WINDS ARE EXPECTED TO INCREASE WEDNESDAY OVER THE
PLAINS WHICH WILL AIDE IN THE WARMING TREND. WINDS COULD APPROACH
HIGH WIND CRITERIA OVER THE ROCKY MOUNTAIN FRONT WEDNESDAY AFTERNOON
BUT THERE ARE SOME DIFFERENCES AMONGST THE MODELS. FOR NOW WILL HOLD
OFF ON ISSUING ANY HIGH WIND WATCH IN THAT AREA FOR WEDNESDAY. BLANK

WEDNESDAY NIGHT THROUGH MONDAY...EXPECT A RATHER QUIET AND MILD
PERIOD OF WEATHER FOR WEDNESDAY NIGHT THROUGH THURSDAY
NIGHT...BEFORE THINGS GET A BIT MORE ACTIVE AND UNSETTLED BEGINNING
ON FRIDAY. WITH AN UPPER LEVEL RIDGE OF HIGH PRESSURE OVER THE
REGION ON THURSDAY...EXPECT ONE MORE MILD AFTERNOON BUT A WINDY DAY
OVER THE REGION. THERE IS A POTENTIAL FOR HIGH WINDS AT LEAST OVER
THE ROCKY MOUNTAIN FRONT IF NOT FARTHER EAST...AND THIS WILL BE
MONITORED CLOSELY OVER THE NEXT FEW DAYS. FOR FRIDAY THROUGH
MONDAY...GENERALLY THE GFS/ECMWF HAVE DIFFERENT SOLUTIONS...AND THUS
WENT MORE WITH A COMPROMISE BETWEEN THE TWO MODELS. OVERALL...COOLER
TEMPERATURES SHOULD START TO MOVE BACK INTO THE REGION ON
FRIDAY...WITH SEASONABLE AIR RESIDING OVER THE REGION FOR THE
WEEKEND. THE COOLEST AIR WILL BE FOUND IN THE HAVRE AREA...WHILE
SOUTHWEST MONTANA WILL BE COOLER THAN IT HAS BEEN...BUT STILL COULD
HAVE AFTERNOON TEMPERATURES A FEW DEGREES ABOVE NORMAL THIS WEEKEND.
IN TERMS OF SNOWFALL...EXPECT SCATTERED SNOW SHOWERS OVER THE REGION
THIS WEEKEND...WITH THE BEST CHANCE FOR SNOW IN THE MOUNTAINS. AS OF
NOW...NO MODEL INDICATES ANY SIGNIFICANT SNOWFALL THIS
WEEKEND...THUS LOW CHANCES OF POPS...BUT WE WILL CONTINUE TO MONITOR
THIS. BRUSDA
