AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
340 AM MDT WED APR 12 2006

.DISCUSSION...

TODAY AND TONIGHT...THE UPPER LEVEL FLOW WILL TRANSITION FROM
WESTERLY TO SOUTHWESTERLY AS WEAK UPPER LEVEL RIDGING SHIFTS EAST OF
THE AREA. EXPECT A FEW SHOWERS AND ISOLATED THUNDERSTORMS TO DEVELOP
LATE THIS AFTERNOON AND EVENING ACROSS THE PLAINS AS A SHORT WAVE
TROUGH ENTERS THE REGION. SCATTERED TO NUMEROUS SHOWERS ARE ALSO
EXPECTED OVER THE MOUNTAINS. EXPECT A HIGH WIND EVENT TO COMMENCE
ALONG THE ROCKY MOUNTAIN FRONT STARTING LATE TONIGHT AS THE SHORT
WAVE ENERGY PASSES ALONG THE CANADIAN BORDER. HAVE UPGRADED THE HIGH
WIND WATCH TO A WARNING ALONG THE ROCKY MOUNTAIN FRONT. TEMPERATURES
WILL BE MILD.

THURSDAY AND THURSDAY NIGHT...BRISK WESTERLY FLOW ALOFT WILL
CONTINUE OVER MONTANA. ISOLATED SHOWERS WILL DEVELOP ACROSS THE
PLAINS AS WEAK ENERGY PASSES THROUGH THE REGION. MORE NUMEROUS
SHOWERS ARE AGAIN EXPECTED OVER THE MOUNTAINS. PRESSURE GRADIENTS
WILL QUICKLY TIGHTEN IN THE LOWER LEVELS. THE STRONG WINDS AT
MOUNTAIN TOP LEVEL WILL HAVE NO PROBLEM MIXING DOWN TO THE PLAINS.
THERE IS A BIT OF CONCERN FOR MOUNTAIN WAVES GIVEN THE EXPECTED
TEMPERATURE AND WIND PROFILES. WILL LEAVE THE HIGH WIND WATCH GOING
FOR EASTERN GLACIER COUNTY AND PASS THESE CONCERNS ON TO THE DAY
SHIFT. THE STRONG WINDS OVER THE PLAINS WILL QUICKLY DECREASE
THURSDAY EVENING. ANOTHER PIECE OF ENERGY WILL KEEP THE WINDS GOING
ALONG THE ROCKY MOUNTAIN FRONT...SO WILL KEEP THE HIGH WIND WARNING
GOING THERE THROUGH 12Z FRIDAY. TEMPERATURES WILL REMAIN MILD.

FRIDAY...THE UPPER LEVEL FLOW WILL TURN MORE SOUTHWESTERLY AS
HEIGHTS LOWER ACROSS THE PACIFIC NORTHWEST. ENOUGH MOISTURE AND
INSTABILITY WILL EXIST BY THE AFTERNOON TO GENERATE SHOWERS AND
ISOLATED THUNDERSTORMS. BREEZY WEST TO SOUTHWEST WINDS ARE AGAIN
EXPECTED OVER THE PLAINS. TEMPERATURES WILL BE WELL ABOVE NORMAL.
SCHAUMANN

FRIDAY NIGHT THROUGH MONDAY NIGHT...AN UPPER LEVEL HIGH PRESSURE
RIDGE WILL MOVE EAST OF THE ZONES FRIDAY NIGHT WHILE LOW PRESSURE
MOVES OVER THE WEST COAST. MOIST SOUTHWEST FLOW AHEAD OF THIS LOW
PRESSURE SYSTEM WILL KEEP THE AIRMASS MOIST AND UNSETTLED.  MOST
AFTERNOONS AND EVENINGS WILL SEE THE AIRMASS BECOMES SLIGHTLY
UNSTABLE THROUGH SUNDAY. SEVERAL STRONGER DISTURBANCES MOVE THROUGH
THIS UPPER FLOW AND ON SATURDAY...A COLDFRONT ASSOCIATED WITH ONE OF
THESE DISTURBANCES MOVES ACROSS THE ZONES AND TEMPS WILL DROP BACK
TO NEAR OR SLIGHTLY BELOW NORMALS THROUGH THE PERIOD. BY
MONDAY...THE MAIN UPPER LEVEL SYSTEM WILL BE APPROACHING THE ROCKIES
AND MOVING OVER THE ZONES DURING THE NIGHT.  ZELZER

TUESDAY THROUGH WEDNESDAY...MODELS PRESENT A SIMILAR SOLUTION DURING
THIS PERIOD...HOWEVER ECMWF IS MORE PROGRESSIVE THAN GFS.  I WENT
WITH A COMPROMISE SOLUTION OF AN AN UPPER LEVEL LOW PRESSURE SYSTEM
MOVING ACROSS THE FORECAST AREA TUESDAY.  MOSTLY CLOUDY SKIES ARE
EXPECTED WITH ISOLATED TO SCATTERED RAIN OR SNOW SHOWERS FOR MOST
AREAS...SNOW SHOWERS ARE LIKELY ALONG THE NORTHERN CONTINENTAL
DIVIDE.  NO REAL COLD AIR WITH THIS SYSTEM...SO TEMPERATURES SHOULD
BE ONLY A FEW DEGREES BELOW SEASONAL NORMALS.  WEAK HIGH PRESSURE
BUILDS OVER THE NORTHERN ROCKIES WEDNESDAY FOR DRIER AND WARMER
CONDITIONS.  HOWEVER THERE WILL BE ENOUGH MOISTURE IN A WESTERLY
UPPER AIR FLOW FOR SCATTERED SHOWERS OVER THE WESTERN AND NORTHERN
MOUNTAINS.  EK

.AVIATION...
UPDATED 2330Z
VFR CONDITIONS. ISOLATED MVFR CEILINGS IN RAIN SHOWERS AND ISOLATED
THUNDERSTORMS WEDNESDAY AFTERNOON. GUSTY WINDS TO INCREASE AGAIN ON
WEDNESDAY AROUND 18Z. CAMP

.HYDROLOGY...
WITH ABOVE NORMAL TEMPERATURES AND SCATTERED SHOWERS EXPECTED OVER
THE HIGHER ELEVATIONS FOR THE REST OF THE WEEK...EXPECT RIVERS AND
STREAMS TO SHOW SOME RISES DUE TO RUNOFF AND SNOWMELT. HOWEVER...NO
MAJOR HYDRO ISSUES ARE EXPECTED IN THE SHORT TERM.
