AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
329 PM MDT TUE MAR 11 2008

.DISCUSSION...

TONIGHT THROUGH THURSDAY...THE SHORTWAVE TROUGH OVER THE PACIFIC
NORTHWEST AND SOUTHWEST CANADA THIS AFTERNOON WILL CONTINUE TO
MOVE EAST ACROSS MONTANA TONIGHT. THIS WILL CONTINUE THE STRONG
WESTERLY DOWNSLOPE WINDS ACROSS MOST OF THE AREA...EXCEPT FOR THE
PROTECTED VALLEYS OF SOUTHWEST MONTANA. RAIN AND SNOW SHOWERS WILL
ALSO BE LIKELY OVER THE MOUNTAINS THIS EVENING JUST AHEAD OF THE
SHORTWAVE...WITH ONLY ISOLATED SHOWERS OVER THE PLAINS. SHOWERS
WILL GRADUALLY DECREASE OVERNIGHT AS THE SHORTWAVE MOVES INTO THE
AREA. A STRONG BUT MORE NORTHWESTERLY FLOW ALOFT WILL BE OVER
NORTH CENTRAL AND SOUTHWEST MONTANA ON WEDNESDAY IN THE WAKE OF
THE SHORTWAVE...WHICH WILL KEEP A CHANCE OF SHOWERS MAINLY OVER
THE MOUNTAINS. HOWEVER...DISTURBANCES IN THE FLOW OVER THE EASTERN
ZONES WILL KEEP A SLIGHT CHANCE OF SHOWERS THERE. STRONG WESTERLY
SURFACE WINDS WILL ALSO CONTINUE THROUGH THE DAY. DESPITE
TEMPERATURES COOLING SOMEWHAT WITH THE PASSAGE OF THE
SHORTWAVE...THE DOWNSLOPE WINDS WILL KEEP TEMPERATURES NEAR TO
SLIGHTLY ABOVE NORMAL. THE UPPER LEVEL RIDGE OVER THE WESTERN
CONUS WILL BUILD NORTHEAST INTO WESTERN AND CENTRAL MONTANA
WEDNESDAY NIGHT INTO THURSDAY...WHICH WILL DECREASE THE WINDS
ALOFT AND AT THE SURFACE. HOWEVER...MOISTURE WITHIN THE WESTERLY
FLOW OF THE RIDGE WILL MOVE INTO SOUTHWEST MONTANA DURING THIS
TIME...FOR AN INCREASING CHANCE OF PRECIPITATION THERE AND INTO
THE WESTERN MOUNTAINS. THE PLAINS WILL REMAIN DRY DURING THIS
TIME. TEMPERATURES WILL COOL A BIT MORE WEDNESDAY NIGHT INTO
THURSDAY...BUT THEY WILL REMAIN NEAR NORMAL.  COULSTON

THURSDAY NIGHT THROUGH SUNDAY NIGHT...MODERATE WEST FLOW ALOFT
WILL CONTINUE OVER THE ZONES BUT SEVERAL WEAK DISTURBANCES WILL
KEEP THE AIRMASS UNSETTLED. A LOW PRESSURE TROF WILL MOVE OVER
THE WEST COAST SATURDAY MORNING AND MOVE THROUGH THE PACIFIC
NORTHWEST DURING THE DAY. WEAK HIGH PRESSURE WILL REMAIN OVER THE
ZONES INTO SATURDAY BUT FLOW ALOFT WILL SWITCH TO THE SOUTHWEST
DURING THE DAY AND HEIGHTS WILL BEGIN TO FALL. DYNAMICS WILL BE
WEAK OVER THE REGION AND ANY PRECIPITATION WILL BE RATHER
DISORGANIZED...AND WILL CONTINUE WITH SLIGHT CHANCE TO CHANCE
POPS ACROSS THE AREA. THE UPPER LEVEL TROF WILL BE OVER THE ZONES
SUNDAY WHILE TO THE NORTH...SURFACE HIGH PRESSURE WILL BE OVER
ALBERTA. THIS HIGH PRESSURE WILL ACROSS THE BORDER DURING THE
DAY. TIMING IS STILL AN ISSUE BUT WILL BUMP POPS A BIT TO CHANCE
TO ACCOUNT FOR THE SOUTHWARD PASSAGE OF THE COLDFRONT AND
RESULTING UPSLOPE FLOW. TEMPS WILL GENERALLY REMAIN ABOVE NORMALS
UNTIL COOLING ON SUNDAY...MAX TEMPS ACROSS NORTH CENTRAL MONTANA
WILL DROP BELOW NORMALS. ZELZER

MONDAY AND TUESDAY...LATEST MODELS DEPICT A NORTHWEST FLOW WITH
PACIFIC DISTURBANCES FLOWING THROUGH. MAINTAINED A CHANCE FOR
PRECIPITATION FOR THE MOUNTAINS AND THE PLAINS. TEMPERATURES ARE
EXPECTED TO BE NEAR NORMAL THROUGH THE PERIOD. SAUCIER

.AVIATION...
UPDATED AT 1745Z.
A WEATHER DISTURBANCE ALOFT WILL BE MOVING THROUGH THE AREA THIS
AFTERNOON. ALTHOUGH THERE IS SOME MOISTURE WITH IT THE AIRMASS
LOOKS FAIRLY STABLE SO EXPECT PRECIPITATION TO BE CONFINED MAINLY
TO THE MOUNTAINS. THE MAIN FORECAST PROBLEM WILL BE WINDS FOR
THIS AFTERNOON. ALTHOUGH AM CONFIDENT THERE WILL BE GUSTY WINDS
BY LATE AFTERNOON AM UNSURE AS TO EXACTLY WHAT HOUR THEY WILL
DEVELOP AT KHVR/KLWT/KHLN/KBZN. THEY ALREADY HAVE DEVELOPED AT
KGTF AND KCTB. AT KCTB WOULD NOT BE SURPRISED TO SEE BRIEF WEST
WINDS OF NEAR 40KTS WITH GUSTS TO 50KTS. FOR TONIGHT WINDS WILL
DIMINISH BUT AGAIN AM UNSURE EXACTLY HOW MUCH THEY WILL DROP OFF.
THE PASSAGE OF ANOTHER WEATHER SYSTEM IN THE NORTH WILL BRING
SOME CLOUDINESS TO KHVR OVERNIGHT BUT AGAIN DO NOT SEE MUCH
CHANCE OF PRECIPITATION.
