WESTERN MONTANA AND NORTH CENTRAL IDAHO FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
835 PM MDT MON OCT 8 2001

.SHORT TERM...UPDATES PLANNED FOR ZONE/STATE BY 900 PM MDT THIS
EVENING. THE UPPER TROUGH AXIS WILL MOVE OVER THE AREA TONIGHT...WITH
SOME PRETTY COOL AIR ALOFT (H5 TEMPS -24 TO -27C). THE AIR MASS WILL
REMAIN UNSTABLE ENOUGH TO SUPPORT SCATTERED LIGHT SHOWERS AFTER
MIDNIGHT...BEFORE DECREASING PRIOR TO SUNRISE. HOWEVER...THUNDER
SHOULD BE ENDING SHORTLY WITH EVENING WEST WINDS ALREADY DIMINISHING.
WILL ADJUST FORECAST ACCORDINGLY.

THE UPPER TROUGH AXIS WILL SHIFT EAST OF THE CWA TUESDAY WITH A
NORTHWEST FLOW DEVELOPING. CURRENT FORECAST KEEPS OROGRAPHIC SHOWERS
IN THE MIX AND THIS LOOKS GOOD. SURFACE HIGH PRESSURE CONTINUES TO
BUILD INTO THE REGION FROM THE WEST...OFFERING ANOTHER BREEZY DAY
FOR TUESDAY CWA-WIDE . MSJ

.MSO...NONE.
