AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MISSOULA MT
747 PM MDT SUN MAR 28 2010

.UPDATE...CANCELLED THE WIND ADVISORY FOR THE HELLS CANYON/CAMAS
PRAIRIE REGION.

&&

.DISCUSSION...THE LOWER ATMOSPHERE HAS STABILIZED ENOUGH IN THE
ADVISORY LOCATIONS ALLOWING WINDS TO DECREASE BELOW ADVISORY
CRITERIA. WINDS WILL CONTINUE TO BE GUSTY OVERNIGHT TONIGHT WITH
SUSTAINED 15-25 MPH AND GUSTS HIGHER THAN 30 MPH. MODEL CROSS
SECTIONS AND SOUNDINGS SUGGEST THAT THE CAMAS PRAIRIE WILL QUICKLY
DESTABILIZE MONDAY MORNING WITH WIND GUSTS IN ACCESS OF 40 MPH
POSSIBLE THROUGH MONDAY EVENING. THIS COULD WARRANT ANOTHER WIND
ADVISORY FROM MONDAY MORNING THROUGH MONDAY EVENING.

&&

.AVIATION...MOIST SOUTHWEST FLOW WILL INCREASE MID LEVEL MOISTURE
AND KEEP BREEZY SURFACE TO MID LEVEL WINDS ACROSS THE NORTHERN
ROCKIES THIS EVENING AHEAD THE NEXT MAJOR WEATHER SYSTEM. RADAR
RETURNS SHOW LIGHT SHOWERS ACROSS CENTRAL OREGON AND SOUTH CENTRAL
IDAHO THAT WILL CONTINUE TO DRIFT AND DEVELOP THROUGH THE REGION
OVERNIGHT SUNDAY. SHOWERS WILL BECOME MORE WIDESPREAD AND
IMPACTING NORTHERN AIRFIELDS..SPECIALLY KGPI AND KMSO BY MONDAY
MORNING BETWEEN 29/0700Z AND 29/1100Z RESPECTIVELY. INCREASED
SURFACE WINDS WILL START UP AGAIN AS SECOND AND STRONGER FRONT
ENTER THE AREA BY LATE MONDAY MORNING...ALSO INCREASING SHOWER
COVERAGE NEAR OR AT ALL AIRFIELDS BY 29/1800Z. EXPECT LOWERED
CEILINGS...REDUCED VISIBILITIES AND TERRAIN BLOCKING FROM
THICKENING CLOUDS AND SHOWERS.

&&

.PREV DISCUSSION... /ISSUED 301 PM MDT SUN MAR 28 2010/

..A VERY MOIST AND DYNAMIC PACIFIC STORM SYSTEM WILL IMPACT THE
NORTHERN ROCKIES TONIGHT THROUGH WEDNESDAY MORNING...

DISCUSSION...A SERIES OF IMPACTS WILL BE EXPERIENCED ACROSS
WESTERN MONTANA AND NORTH CENTRAL IDAHO THROUGH THE NEXT THREE
DAYS.

FIRST...GUSTY WINDS WILL CONTINUE ACROSS CENTRAL IDAHO AND WESTERN
MONTANA THROUGH THE REMAINDER OF THIS AFTERNOON AND INTO THE
EVENING HOURS. THE ATMOSPHERE HAS BECOME QUITE UNSTABLE WHICH HAS
ALLOWED STRONGER MOUNTAIN TOP WINDS FROM ALOFT TO MIX TO MANY
VALLEY FLOORS. A WIND ADVISORY WILL REMAIN IN EFFECT ACROSS THE
GRANGEVILLE...CAMAS PRAIRIE...LOWER SALMON RIVER AND HELL'S CANYON
REGIONS THROUGH 03Z THIS EVENING. BREEZY WINDS WILL LIKELY
CONTINUE THROUGHOUT THE NIGHT WHICH WILL HELP KEEP VALLEYS FROM
STABILIZING AND THUS LEAD TO WARM OVERNIGHT TEMPERATURES. TOMORROW
WILL BE YET AGAIN ANOTHER BREEZY TO WINDY DAY WITH THE POTENTIAL
YET AGAIN DURING THE AFTERNOON FOR SOME DECENT GUSTS. HOWEVER
WITHOUT THE PRESENCE OF A MOUNTAIN TOP STABLE LAYER IN THE
GRANGEVILLE/CAMAS PRAIRIE REGION TO HELP MIX UPPER LEVEL WINDS TO
THE SURFACE...BELIEVE AN ADVISORY MAY NOT BE NECESSARY. HOWEVER
WIND SPEEDS ACROSS THE REGION MAY INCREASE IN ADVANCE OF A SERIES
OF COLD FRONTS APPROACH THE REGION LATE MONDAY AFTERNOON THROUGH
TUESDAY.

SECONDLY...A DEEP FETCH OF SUB-TROPICAL MOISTURE...BETWEEN 175% AND
200% OF NORMAL...WHICH SPANS EAST ALMOST AS FAR AS HAWAII CAN
CLEARLY BE SEEN ON SATELLITE IMAGERY. THE FIRST WAVE OF THIS
MOISTURE MOVED INLAND THIS MORNING/AFTERNOON ALONG WITH A WARM
FRONT AND UPPER LEVEL JET MAX. THIS RESULTED IN A QUICK BURST OF
HEAVY PRECIPITATION OVER THE COLUMBIA MOUNTAINS AND BROUGHT MUCH
OF OUR WIND TODAY ACROSS THE REGION. BELIEVE THIS IS ONLY THE
BEGINNING OF A EXCEPTIONALLY WET NEXT FEW DAYS WITH THE POTENTIAL
FOR SOME FAVORED UP-SLOPE LOCATIONS...SUCH AS THE
BITTERROOT/CLEARWATER MOUNTAINS...PIERCE...HEADQUARTERS...LOWELL...
LOLO/LOOKOUT/LOST TRAIL PASSES...SEELEY LAKE AND PORTIONS OF
GLACIER NATIONAL PARK TO RECEIVE BETWEEN 1 AND 2 INCHES TOTAL
LIQUID BY EARLY WEDNESDAY MORNING. FORECAST MODELS CONTINUE TO
HONE IN ON THESE AREAS AS FOCUS FOR HEAVIEST PRECIPITATION AND THE
TIMING OF THIS PRECIPITATION. LIGHT PRECIPITATION WILL START LATE
TONIGHT BUT THE HEAVIEST AMOUNTS ARE NOT EXPECTED UNTIL THE
STRONGEST FRONTAL PASSAGE ANTICIPATED BETWEEN MONDAY AFTERNOON AND
TUESDAY MORNING. THE PROLONGED PERIOD OF MODERATELY HEAVY RAIN AND
HIGH MOUNTAIN SNOWFALL WILL BE ACCENTUATED BY A SLOW MOVING...VERY
DYNAMIC FRONT AND ASSOCIATED 150 KNOT JET STREAM.

THIRD...SNOWFALL FROM THIS STORM SYSTEM WILL FIRST BE CONFINED TO
THE HIGHEST TERRAIN AS WARM AIR IN ADVANCE OF THE SYSTEM WILL
RAISE SNOW LEVELS ABOVE ALL PASS LEVELS. SNOW LEVELS ARE EXPECTED
TO FALL TUESDAY NIGHT AS COLD AIR MOVES INTO THE REGION BEHIND THE
STRONG COLD FRONT. GIVEN THAT THE HEAVIEST PRECIPITATION IS
EXPECTED BEFORE THE COLD AIR ARRIVES...BELIEVE AT THIS TIME STORM
TOTAL SNOW AMOUNTS WILL BE BELOW WARNING AMOUNTS AT LOOKOUT AND
LOLO PASS. HOWEVER THERE WILL BE A TIME...LIKELY ALONG AND JUST
BEHIND THE FRONT TUESDAY NIGHT WHERE A BRIEF BURST OF HEAVY...WET
SNOWFALL IS POSSIBLE GENERATING QUICK ACCUMULATIONS OF 3 TO 6
INCHES. BUT WARMER ROADWAYS IN LATE MARCH WILL LIKELY PREVENT
MUCH OF THIS FROM STICKING ALL AT ONCE.

..TUESDAY NIGHT...EXPECT NUMEROUS SHOWERS TO CONTINUE ACROSS THE
NORTHERN ROCKIES AS AN UPPER LEVEL FEATURE MOVES THROUGH BEHIND
THE EXITING COLD FRONT. THERE IS SOME UNCERTAINTY AS TO THE EXACT
LOCATION OF THE SHORT WAVE BUT SOME MODERATE MOUNTAIN SNOWS MAY BE
POSSIBLE WHERE THE SHORT WAVE MOVES THROUGH.

WEDNESDAY...THE ELONGATED UPPER LEVEL TROF WILL EXTEND FROM THE
NORTHERN ROCKIES THROUGH THE DESERT SOUTHWEST THROUGH MUCH OF
THURSDAY. THE STRONGEST DYNAMICS AND PRECIPITATION IS EXPECTED TO
BE IN THE GREAT BASIN AND SOUTHWARD. BUT THERE WILL BE PLENTY OF
INSTABILITY AND LOW LEVEL MOISTURE IN THE NORTHERN ROCKIES TO
PRODUCE SHOWERS THROUGHOUT THE PERIOD...ESPECIALLY IN THE
AFTERNOONS AND EVENINGS.

FRIDAY AND SATURDAY...MODELS ARE INDICATING ANOTHER STRONG UPPER
LEVEL FEATURE TO PENETRATE THE PACIFIC NORTHWEST AND NORTHERN
ROCKIES. TIMING AND STRENGTH IS SOMEWHAT UNCERTAIN AT THIS TIME
BUT CONFIDENCE IS HIGH IN YET ANOTHER UNSETTLED PERIOD LATE NEXT WEEK.

AVIATION...MOIST SOUTHWEST FLOW WILL INCREASE MID LEVEL MOISTURE
AND KEEP BREEZY SURFACE TO MID LEVEL WINDS ACROSS THE NORTHERN
ROCKIES THIS EVENING AHEAD THE NEXT MAJOR WEATHER SYSTEM. RADAR
RETURNS SHOW LIGHT SHOWERS ACROSS CENTRAL OREGON AND SOUTH CENTRAL
IDAHO THAT WILL CONTINUE TO DRIFT AND DEVELOP THROUGH THE REGION
OVERNIGHT SUNDAY. SHOWERS WILL BECOME MORE WIDESPREAD AND
IMPACTING NORTHERN AIRFIELDS..SPECIALLY KGPI AND KMSO BY MONDAY
MORNING BETWEEN 29/0700Z AND 29/1100Z RESPECTIVELY. INCREASED
SURFACE WINDS WILL START UP AGAIN AS SECOND AND STRONGER FRONT
ENTER THE AREA BY LATE MONDAY MORNING...ALSO INCREASING SHOWER
COVERAGE NEAR OR AT ALL AIRFIELDS BY 29/1800Z. EXPECT LOWERED
