WESTERN MONTANA AND NORTH CENTRAL IDAHO FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
240 PM MDT THU APR 30 1998

COOLEST AIR FROM NORTHERN SYSTEM PUSHING INTO EASTERN MONTANA WELL
EAST OF THE DIVIDE. LOOKS LIKE INTERACTION BETWEEN THAT AND THERMAL
LOW IN OREGON WILL CREATE INCREASED EASTERLY FLOW AT VERY LOW
LEVELS...BUT COOLING DOES NOT LOOK LIKE MUCH. BEST NEWS IS THAT
SLIGHT INCREASE IN WIND SHOULD HELP THE HAZE SITUATION. WILL KEEP MIN
TEMPS UP TONIGHT DUE TO ENHANCED DRAINAGE WINDS IN THE EAST/WEST
VALLEYS...AND KEEP HIGHS ON FRIDAY STEADY AS COOLER AIR PULLS OUT TO
EAST. THEN COOLER FRIDAY NIGHT WITH REDUCED WIND...AND STEADY TEMPS
ON SATURDAY MOST AREAS SINCE HEIGHTS AND TEMPS INCREASE BUT SHOULD
SEE AN OFFSETTING INCREASE IN CLOUDS AS WELL. DONT SEE ENOUGH
MOISTURE YET ON SATURDAY TO INDICATE ANY CHANCE OF THUNDERSTORMS
EXCEPT IN WESTERN IDAHO. BARKER.

...FORECASTS BELOW ARE PRELIMINARY AND SUBJECT TO CHANGE...
