.SHORT TERM...Mid/high clouds from tropical storm Madeline east
of Hawaii have streamed into our CWA.  No rain is expected until
late Tuesday when we have a slight chance of thunderstorms in
Baker County and northern-most Harney County.  The cloud band
will shift to Idaho Wednesday and a slight chance of thunder-
storms is forecast for Twin Falls County and northward into
Camas County Wednesday afternoon.  Tuesday will be hot with
highs 95 to 100 in the Treasure Valley and western Magic Valley,
and 85 to 95 elsewhere.  Wednesday will cool 3 to 5 degrees as a
north Pacific upper trough moves onshore.  Southwest winds aloft
should push the smoke out of the Treasure Valley tonight and
Tuesday.  Gusty southwest winds at the surface also expected
in southern Malheur and Harney Counties late today and again
Tuesday afternoon and evening.  Not so windy elsewhere.

.LONG TERM...Wednesday night through Monday...An upper low off the
British Columbia coastline tracks southward Thursday increasing
precipitation chances, mostly for our northern zones. The associated
cold front starts to pass through our Oregon zones Thursday morning
and our Idaho zones by Friday afternoon. This frontal passage will
cause temperatures to drop about 10 degrees from Thursday`s highs
which puts most places 5-8 degrees below normal. The forecast
remains unsettled through the end of the period with some shortwaves
passing through, but the majority of the moisture stays north of
our area.


.AVIATION...VFR with areas of MVFR/IFR conditions in and around
wildfires. Surface winds, variable 5-10 kts with gusty winds 15-25
kts around KBKE/KMYL through Monday evening. Winds aloft to 10k feet
MSL, southwest 10-30 kts.


ID...Red Flag Warning from 2 PM MDT Tuesday until 9 PM MDT Tuesday
OR...Red Flag Warning until 9 PM MDT /8 PM PDT/ Tuesday
