AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
253 PM MDT FRI MAR 27 2009
...SPRING SNOW STORM TO IMPACT NORTH CENTRAL IDAHO AND WESTERN
MONTANA THIS WEEKEND...
.DISCUSSION...A STRONG PACIFIC STORM SYSTEM WILL MOVE THROUGH
NORTH CENTRAL IDAHO AND WESTERN MONTANA LATE SATURDAY THROUGH
SUNDAY. A SURFACE COLD FRONT ASSOCIATED WITH THIS SYSTEM WILL HELP
LOWER SNOW LEVELS TO THE VALLEY FLOORS BY SUNDAY MORNING AS IT
SWEEPS THROUGH THE REGION. AN INCREASED PRESSURE GRADIENT WITH
THIS SYSTEM WILL RESULT IN AREAS OF WIND AND BLOWING SNOW. THIS
WILL LIKELY INCREASE THE POTENTIAL FOR HAZARDOUS DRIVING
CONDITIONS OVER LOOKOUT AND LOLO PASSES AND MARIAS PASS ALONG THE
DIVIDE. ALSO...LOCATIONS IN NORTH CENTRAL IDAHO OVER THE CENTRAL
AND SOUTHERN CLEARWATER MOUNTAINS AND THE WHITEBIRD AND GREER
GRADES OF IDAHO ARE EXPECTED TO BE IMPACTED. THE POTENTIAL FOR
LOCAL BLIZZARD CONDITIONS EXISTS FOR ALL THE ABOVE MENTIONED
REGIONS SATURDAY NIGHT THROUGH SUNDAY EVENING. THE MODELS ARE IN
DECENT AGREEMENT WITH THIS SYSTEM...BUT DO DIFFER SOMEWHAT ON
SURFACE FEATURE TIMING AND BEST PRECIPITATION AMOUNTS AS WELL AS
PLACEMENT ON SUNDAY...ESPECIALLY IN SOUTHWEST MONTANA. THIS WILL
BE AN AREA TO WATCH AS THE MODELS COME INTO BETTER AGREEMENT.
THEREFORE A WINTER STORM WATCH HAS BEEN ISSUED. PLEASE SEE
HEADLINE SECTION BELOW FOR LOCATION AND TIMING SPECIFICS.
THIS SYSTEM WILL MOVE SOUTHEAST OF THE REGION SUNDAY NIGHT...BUT A
MOIST NORTHWEST FLOW BEHIND IT WILL KEEP SHOWERS IN THE
FORECAST. A JET ON THE BACK SIDE OF THE EXITING SYSTEM DOES KEEP
THE POSSIBILITY OF STRONG SNOW BANDS SETTING UP IN WEST CENTRAL
MONTANA TOWARD MONDAY MORNING.
ANOTHER SYSTEM LOOKS TO IMPACT THE INTERMOUNTAIN REGION EARLY NEXT
WEEK. AT THIS TIME THERE ARE SOME TIMING ISSUES...BUT MONDAY NIGHT
THROUGH WEDNESDAY IS THE GENERAL TIME FRAME TO KEEP ALERT TO.
&&
.AVIATION...A WEAK DISTURBANCE WILL CROSS THE NORTHERN ROCKIES
TONIGHT PRODUCING RAIN AND SNOW SHOWERS. NORTHWEST FLOW ALOFT
COMBINED WITH A JET STREAK ENTERING THE AREA WILL PROVIDE THE
FOCUS FOR UPSLOPE-ENHANCED PRECIPITATION AFTER MIDNIGHT. THIS
PRECIPITATION WILL BE LOCATED PRIMARILY ACROSS NORTHWEST
MONTANA...THE GLACIER PARK AREA...THE MISSION MOUNTAINS AND THE
CLEARWATER MOUNTAINS OF IDAHO. MOUNTAINS AND PASSES WILL BECOME
OBSCURED AFTER MIDNIGHT. AIRFIELD OPERATIONS IMPACTED BY LOWER
CEILINGS AND PRECIPITATION WILL MAINLY BE KGPI. A POTENT SPRING
SNOW STORM WILL IMPACT THE NORTHERN ROCKIES LATE SATURDAY THROUGH
SUNDAY.
&&
.MSO WATCHES/WARNINGS/ADVISORIES...
MT... WINTER STORM WATCH FROM SATURDAY EVENING THROUGH SUNDAY EVENING
FOR LOWER CLARK FORK REGION-WEST GLACIER REGION.
