.SHORT TERM...Tonight through Sunday night.

A steady stream of precipitation extends from eastern Idaho to
northern California where a low pressure system is centered this
afternoon. This low pressure system will move into eastern Idaho
tonight which will bring an end to the rainfall across the region.
Expect dry weather for most locations on Saturday. However,
another storm system will arrive Sunday. This will overspread
precipitation Sunday afternoon into Sunday evening with rainfall
amounts between a quarter and a half an inch likely. Snow levels
will remain high, generally greater than 9000 feet. Therefore
expect few snow impacts from this next system.


.LONG TERM...Monday through Friday night. Initially models show
drying conditions and slightly warmer than normal temperatures
by Halloween afternoon Monday. Another system bringing mostly
mountain rain and snow showers will move through on Tuesday.
Look for a drying trend under high pressure Wednesday and Thursday
bringing slightly above normal temperatures on Wednesday and well
above normal temperatures on Thursday and Friday. On Friday,
models continue to show differences with the GFS model showing
dry conditions and the ECMWF model bringing another moist system
into through the area Friday through Saturday morning. Wyatt


.AVIATION...A very moist system is moving through the area this
afternoon into early evening. Expect MVFR/IFR conditions with
intermittent rain showers on station. Rain will end around midnight
for our most Western TAF sites and a little later with our most
Eastern TAF Sites. Expect lingering MVFR Cigs until around Mid morning.
Also...Expect winds to slightly pick up in the early morning and
continue through the early afternoon. Expect a brief dry period
Saturday before another moist system moves through the area on Sunday.
