AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1125 AM MST WED FEB 23 2011

.AVIATION...
UPDATED 1800Z.
A BROAD UPPER LEVEL TROUGH OF LOW PRESSURE OVER MONTANA WILL
CONTINUE TO DOMINATE WITH SURFACE HIGH PRESSURE PULLING IN COLD AIR FROM
THE NORTH. MOISTURE MOVING OVER THE COLD AIR IS CREATING WIDESPREAD
AREAS OF SNOW WITH MVFR AND IFR CONDITIONS...PARTICULARLY OVER
NORTHERN ROUTES. IT IS EXPECTED THAT THESE CONDITIONS WILL PERSIST
OVER NORTHERN ROUTES THROUGH THE NEXT 24 HOUR PERIOD AS WELL AS
SPREAD INTO SOUTHERN ROUTES AFTER 03Z. JOH

.UPDATE...COMPLEX FORECAST SITUATION EXISTS THIS MORNING AS AN
UPPER LEVEL TROUGH CONTINUES TO DEVELOP OVER WESTERN USA. ARCTIC
AIR WILL CONTINUE TO FLOW INTO THE FORECAST AREA WITH TEMPERATURES
EXPECTED TO DROP BELOW ZERO ACROSS MUCH OF THE FORECAST AREA BY
TONIGHT. PRECIPITATION SITUATION IS A BIT MORE MUDDLED AS MOISTURE
CONTINUES TO FLOW OVER NORTH CENTRAL MONTANA BRINGING PERIODS OF
LIGHT SNOW TO THIS PORTION OF THE FORECAST AREA. HOWEVER...
PRECIPITATION IS GENERALLY MISSING SOUTHWEST MONTANA AND ONLY
SCATTERED SNOW SHOWERS ARE EXPECTED THROUGH THE DAY WITH THE
LIKELIHOOD OF SNOW INCREASING AGAIN LATER TONIGHT. AS A RESULT I
HAVE OPTED TO CANCEL THE WINTER WEATHER ADVISORY IN THE SOUTHWEST
BUT WILL LEAVE THE WARNING IN PLACE FOR THE MOUNTAINS OF GALLATIN
COUNTY. IT IS POSSIBLE THAT NEW HIGHLIGHTS COULD BE ISSUED FOR THE
SOUTHWEST WITH THE AFTERNOON PACKAGE...BUT WILL NEED TO LOOK OVER
THE LATEST MODEL RUNS TO BE SURE. ALSO...IT IS POSSIBLE THAT A WIND
CHILL ADVISORY COULD BE ISSUED FOR PORTIONS OF THE FORECAST AREA
AS TEMPERATURES FALL OVERNIGHT...BUT THIS ALSO REQUIRES FURTHER
STUDY WITH A DECISION EXPECTED IN TIME FOR THE AFTERNOON PACKAGE.
MPJ

&&

.HYDROLOGY...
NO CHANGES TO THE CURRENT ICE JAM FLOODING ON THE JEFFERSON RIVER
CONTINUES NEAR SILVER STAR IN NORTHWEST MADISON COUNTY. ADDITIONAL
STREAM RISES SHOULD BE SLOW AND FLASH FLOODING IS NOT EXPECTED.

&&

.PREV DISCUSSION...
/ISSUED 449 AM MST WED FEB 23 2011/
TODAY THROUGH FRIDAY EVENING...ANALYSIS THIS MORNING SHOWS BROAD
LONGWAVE TROF COVERING THE NORTHWEST QUARTER OF THE US AND WESTERN
HALF OF CANADA WITH SEVERAL AREAS OF MOISTURE EMBEDDED WITHIN THE
LARGE SCALE FLOW.  THIS SYSTEM IS EXPECTED TO REMAIN OVER THE REGION
TODAY...BRINGING WIDESPREAD OVERCAST SKIES...PERIODS OF LIGHT TO
OCCASIONALLY MODERATE SNOW...AND SHARPLY COLDER TEMPERATURES.
THOUGH THERE WILL BE BREAKS IN THE PRECIPITATION AT VARIOUS
TIMES/LOCATIONS THRU THE DAY...FORECAST IS STILL ON TRACK FOR AN
ADDITIONAL 2 TO 4 INCHES AT LOWER ELEVATIONS AND 3 TO 6 INCHES IN
THE MTNS...EXCEPT FOR BEAVERHEAD COUNTY WHERE SNOW TOTALS WILL BE
ABOUT HALF OF THESE VALUES. SO HAVE CONTINUED ALL CURRENT WINTER
STORM WARNINGS AND ADVISORIES WITH NO CHANGES AT THIS TIME.
HOWEVER...FOLLOWING SHIFTS MAY NEED TO CONSIDER EXTENDING CURRENT
SNOW HIGHLIGHTS FURTHER INTO THURS AS LATEST FORECAST MODELS KEEP
LIGHT AMOUNTS OF PRECIPITABLE MOISTURE OVER MUCH OF THE REGION INTO
THURS EVE.  ALSO AN ADDITIONAL WIND CHILL HIGHLIGHT IS LOOKING MORE
LIKELY AS WINDS ARE PROJECTED TO STAY ABOVE THE 10 MPH THRESHOLD
EARLY THURS MORNING.  MODELS ARE IN GOOD AGREEMENT THAT THE LONGWAVE
WILL GRADUALLY WEAKEN AND ASSOCIATED MOISTURE WILL DISSIPATE LATE
THURS INTO FRI.  THIS WILL BRING AN END TO THE SNOW...ALONG WITH
DECREASING CLOUD COVER WHICH UNFORTUNATELY WILL AID IN THE FORMATION
OF BITTERLY COLD TEMPS ON FRI MORNING.

MADE ONLY MINOR ADJUSTMENTS TO PREVIOUS TEMPERATURES VALUES FOR THIS
FORECAST PERIOD.  CHILLY ARCTIC AIRMASS WILL CONTINUE TO GRADUALLY
SPREAD OVER THE ENTIRE REGION TODAY.  EXPECT SINGLE DIGIT HIGHS FROM
GREAT FALLS NORTHWARD WITH TEENS AND 20S ELSEWHERE THIS AFTN.  LOW TEMPS
TOMORROW MORNING WILL BE ABOUT 15 DEG COLDER THAN THIS MORNING AND
THURS AFTN HIGHS WILL REMAIN IN THE SINGLE DIGITS BELOW ZERO OVER
CENTRAL MT AND HILINE COUNTIES.  STILL LOOKING FOR COLDEST TEMPS
FROM THIS SYSTEM TO OCCUR FRI MORNING WITH SINGLE DIGITS BELOW ZERO
IN THE SOUTHWEST...DOWN TO 20 TO 30 BELOW ACROSS THE CENTRAL AND
NORTH CENTRAL PLAINS WHERE RECORD LOW TEMPS MAY OCCUR AT SEVERAL
LOCATIONS.  WARANAUSKAS

FRIDAY NIGHT THROUGH WEDNESDAY...ECMWF AND GFS IN RELATIVELY CLOSE
AGREEMENT FOR THE EXTENDED FORECAST. PERIOD STARTS WITH THE
SPLITTING UPPER LEVEL LOW PRESSURE TROUGH EXTENDING FROM CENTRAL
CANADA TO OFF THE PACIFIC COAST WITH MAIN ENERGY BEGINNING TO MOVE
TO THE SOUTH AND EAST AND AWAY FROM MONTANA. AS TROUGH SLOWLY PULLS
AWAY AND BULK OF ENERGY MOVES INTO SOUTHWEST STATES...MODELS SHOW
PATTERN SHIFTING WITH HIGH PRESSURE BEGINNING TO BUILD INTO MONTANA
