AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
1023 AM MDT FRI APR 18 2008

..SIGNIFICANT WINTER WEATHER EVENT TO IMPACT WESTERN MONTANA AND
NORTH CENTRAL IDAHO THIS WEEKEND...

DISCUSSION...FOR TODAY...PRESSURE GRADIENTS WILL TIGHTEN THROUGH
THE DAY ACROSS SW AND WRN MONTANA. A PASSING COLD FRONT WILL ALLOW
FOR MODERATELY STRONG UPPER LEVEL WINDS TO MIX DOWN TO THE
SURFACE. AS A RESULT WIND ADVISORIES HAVE BEEN ISSUED FOR LEMHI
COUNTY. IN OTHER AREAS LIKE SW MT AND THE MISSOULA/BITTERROOT
VALLEYS...WINDS WILL BE GUSTY...BUT THEY SHOULD REMAIN BELOW
ADVISORY LEVELS (40 MPH.) AS THE FRONT MOVES INTO NORTH CENTRAL
IDAHO THIS AFTERNOON...SOME THUNDERSTORM ACTIVITY IS EXPECTED.
WITH THE GOOD MIXING ALONG THE FRONTAL BOUNDARY (AND GIVEN
SOMEWHAT STRONG PRESSURE GRADIENTS)...THERE IS SOME MINOR CONCERN
THAT A FEW OF THE STORMS COULD PRODUCE SEVERE WIND GUSTS OVER
LEMHI COUNTY. THE HWO WILL BE UPDATED TO MENTION THE CONCERN FOR
THIS AFTERNOON.

THE ONLY OTHER THING TO NOTE IS THAT THE MODELS CONTINUE TO SHOW A
CLASSIC ARCTIC SNOW/OVERRUNNING EVENT FOR THE SATURDAY EVENING
THROUGH SUNDAY TIME PERIODS FOR WRN MONTANA. THIS HAS THE
POTENTIAL TO BE A HIGH IMPACT EVENT. IN FACT...MOST WATCHES WILL
BE UPGRADED TO WARNINGS (ADVISORIES FOR THE LOWER VALLEYS) FOR THE
AFTERNOON FORECAST PACKAGE.

AVIATION...A PASSING FRONTAL SYSTEM AND TIGHTENING PRESSURE
GRADIENTS COULD CREATE SOME CROSSWIND CONCERNS AT AIRFIELDS ACROSS
WRN MT TODAY. IN ADDITION...A FEW STRONG TO SEVERE THUNDERSTORMS
ARE POSSIBLE NEAR KSMN THIS AFTERNOON.

PREV DISCUSSION... /ISSUED 505 AM MDT FRI APR 18 2008/

DISCUSSION...VERY ACTIVE WEATHER IS EXPECTED TODAY THROUGH THE
WEEKEND BEGINNING WITH THE PASSAGE OF A STRONG COLD FRONT THIS
AFTERNOON. THIS FRONT IS CURRENTLY IN BRITISH COLUMBIA...POISED TO
MOVE SOUTHEAST THROUGH IDAHO AND WESTERN MONTANA TODAY. SOME
PRECIPITATION WILL BE ASSOCIATED WITH THE FRONT...HOWEVER THE MAIN
STORY WILL BE WIND. AT THIS TIME WIND OBSERVATIONS IN CANADA
DIRECTLY AHEAD OF THE FRONT ARE SUSTAINED IN THE 20 TO 30 MPH
RANGE WHILE GUSTING OVER 40 MPH AT TIMES. I BELIEVE THE FRONT WILL
ONLY STRENGTHEN AS IT MOVES SOUTH INTO THE UNITED STATES TODAY.
THUS HAVE ISSUED A WIND ADVISORY FOR LOCATIONS ACROSS WEST CENTRAL
AND SOUTHWEST MONTANA. THE MISSOULA AND BITTERROOT VALLEY AS WELL
AS BUTTE WILL SEE VERY STRONG WINDS THIS AFTERNOON IN ASSOCIATION
WITH THE PASSAGE OF THIS COLD FRONT.

MODELS SUGGEST A BRIEF LULL IN PRECIPITATION OVERNIGHT TONIGHT
WHILE THE MAIN CLOSED LOW DROPS OUT OF CANADA AND OVER THE PACIFIC
NORTHWESTERN STATES. HOWEVER BY SATURDAY AFTERNOON A MID LEVEL
CIRCULATION AND CONVERGENCE BOUNDARY OR DEFORMATION ZONE WILL
DEVELOP OVER WESTERN MONTANA RESULTING IN WIDESPREAD HEAVY
PRECIPITATION. FORECAST MODELS ARE NOW CONSISTENTLY FOCUSING THE
HEAVIEST PRECIPITATION OVER SOUTHWEST MONTANA...THE CONTINENTAL
DIVIDE AND FAR EAST CENTRAL IDAHO. HAVE CONTINUED THE WINTER STORM
WATCH FOR THESE AREAS...ADDING THE GLACIER NP REGION...SEELEY/POTOMAC
AREA ALONG WITH WESTERN LEMHI COUNTY DUE TO EXPECTED HEAVY SNOWFALL.
HAVE ALSO CHOSEN TO ADJUST THE WATCH FOR EASTERN LEMHI COUNTY...MAKING
IT NOW ABOVE 6000 FEET AND FOCUSING PRIMARILY ON US-93 HEADING UP
TO LOST TRAIL PASSES. LOWER ELEVATIONS WILL EXPERIENCE
ACCUMULATING SNOWFALL...BUT AT THIS TIME DO NOT EXPECT WARNING CRITERIA
TO BE MET.

ALTHOUGH MODEL CONSISTENCY IS EXCELLENT WITH THIS STORM...THE
FORECAST PICTURE HEADING INTO SUNDAY IS QUITE MURKY. ONE THING
WHICH IS CERTAIN...HEAVY PRECIPITATION WILL CONTINUE THROUGH AT
LEAST EARLY SUNDAY. HOWEVER THE EXACT PLACEMENT OF WHERE THE BEST
FORCING WILL BE IN ASSOCIATION WITH THE 700MB CIRCULATION IS STILL
NOT COMPLETELY KNOWN. AT THIS TIME AM GOING WITH THE SLOWEST MODEL
TO MOVE THIS SYSTEM TO THE EAST...WHICH IS THE ECMWF. FORECAST
MODELS HAVE A STRONG TENDENCY TO MOVE THESE CLOSED LOW SYSTEMS OUT
OF THE REGION MUCH TOO SOON. THUS HAVE ADJUSTED THE FORECAST
TOWARDS THE ECMWF WHICH KEEPS CONTINUED PRECIPITATION OVER CENTRAL
IDAHO AND SOUTHWEST MONTANA THROUGH THE DAY ON SUNDAY. LOW AND MID
LEVEL WINDS DURING THIS TIME WILL BECOME QUITE FAVORABLE FOR
AREAS SUCH AS GRANGEVILLE TO RECEIVE ACCUMULATING SNOWFALL AND
POSSIBLY A FAIR AMOUNT. SO WILL CONTINUE TO HIGHLIGHT THIS POTENTIAL
IN A HAZARDOUS WEATHER OUTLOOK.

SUNDAY NIGHT THROUGH THURSDAY...THE CLOSED LOW WILL MOVE OFF TO THE
EAST DURING THE DAY ON MONDAY. A TROUGH WILL REMAIN OVER THE
REGION THROUGH THE REST OF THE WEEK...KEEPING A CHANCE OF SHOWERS
IN EACH DAY...ALONG WITH BELOW NORMAL TEMPERATURES.

AVIATION...CLOUDS WILL BE ON THE INCREASE TODAY AS THE NEXT
WEATHER SYSTEM BEGINS TO AFFECT THE NORTHERN ROCKIES. A COLD FRONT
ASSOCIATED WITH THIS SYSTEM WILL CREATE STRONG AND GUSTY
WINDS...MAINLY IN THE AFTERNOON AS SURFACE PRESSURE GRADIENTS
TIGHTEN. MOUNTAINS AND PASSES WILL BE OBSCURED AT TIMES IN THE
LATE AFTERNOON AND EVENING. THERE IS ALSO THE CHANCE FOR SOME
THUNDERSTORMS THIS AFTERNOON AND EVENING...MAINLY IN THE SOUTH.

PRAIRIE...GRANGEVILLE AND THE WHITE-BIRD GRADE. SNOWFALL
ACCUMULATIONS MAY BECOME MODERATE SUNDAY AND WARRANT THE ISSUANCE
