WESTERN MONTANA AND NORTH CENTRAL IDAHO FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
908 AM MDT SAT OCT 19 2002

.SHORT TERM...WILL UPDATE ZONES ONLY.
GOING FORECAST IN PRETTY GOOD SHAPE...BUT WILL MAKE SOME MINOR
WORDING CHANGES TO CLOUD COVER.  WEAK WAVE ALOFT PUSHING THIN HIGH
CLOUDS INTO THE CWA...BUT WILL LIKELY NOT HAVE A BIG IMPACT ON THE
NICE DAY AHEAD.  THEY MAY BE A BIT THICKER IN THE FAR NORTH THIS
AFTERNOON.  TEMPERATURE FORECAST LOOKS PRETTY GOOD AS THIS WAVE AND
HIGH CLOUDINESS COULD RESULT IN A DROP OF A FEW DEGREES FROM
YESTERDAY.             WHITMORE

.LONG TERM...MADE A FEW CHANGES IN THE LONG TERM...MAINLY TO
REDUCE TEMPS AND TO MAKE SOME PRECIP ADJUSTMENT ON TIMING. MOVED
PRECIP OUT OF THE REGION ABOUT 12 HOURS SOONER ON TUE NIGHT. EXPECT
WINDY CONDITIONS TUE WITH TIGHTENING PRESSURE GRADIENTS OVER THE
NRN ROCKIES.  RETROGRADING TROF TUE WILL BRING COOL NE WINDS ALONG
WITH PRECIP. TEMPS WILL TAKE A DIVE INTO THE 40S FOR HIGHS TUE-THU...
REBOUNDING SLIGHTLY AHEAD OF A TROF MOVING INTO THE PAC NW LATE THU
AND FRI. THIS TROF CONTAINS AMPLE MOISTURE...MORE THAN WE HAVE SEEN
IN QUITE SOMETIME. THE W-E JET SEEMS TO PUSH THROUGH WHAT REMAINS OF
A WEAKENED RIDGE IN THE PAC NW. THIS IS THE SECOND MRF RUN IN A ROW
THAT SUGGESTS A PATTERN CHANGE FROM RIDGE TO TROFINESS OVER THE
NORTHWEST...HENCE CONFIDENCE WAS HIGH ENOUGH TO PUT CHC PCPN CWA WIDE
FRIDAY. RPN

.MSO...NONE.

...7-DAY SPOT TEMPS AND POPS...
