.DISCUSSION...Cooler weather is expected today behind the cold
front. Winds will remain breezy for some but not quite as windy as
yesterday. A low pressure system will drop in from Montana on
Wednesday. This will bring a few showers and thunderstorms to the
central mountains and upper Snake highlands for Wednesday,
Thursday, and possibly into Friday. Another low pressure system
will track south of the region through Utah over the weekend.
Parts of the region closer to the Utah border might see a stray
shower from this system as it passes by. Pattern remains somewhat
active headed into next week as models show a couple more weak
systems moving onshore which could produce a few showers and
thunderstorms. Temperatures will remain cool over the next 7 days.

&&

.AVIATION...Breezy and gusty winds throughout the Snake Plain this
afternoon. Low pressure trough settles southward into the central
mountains Wednesday afternoon with a slight chance of thunderstorms
developing over the higher terrain north and east of KSUN. No
significant weather expected at the other TAF sites. RS

&&

.FIRE WEATHER...The surface pressure gradient remains
moderately strong today from Richfield to Craters of the Moon, east
to about Wayan, and south to Oakley. Minimum relative humidity 8 to
14 percent. The limiting factor is the wind gusts, estimated to be
25-30 mph between Richfield and Pocatello this afternoon and up to
25 mph around Oakley. No Red Flag was issued for today, but it will
still be on the breezy side. Wednesday and Thursday, a low pressure
disturbance will slide  south from Canada into the central Idaho
mountains and bring isolated showers and thunderstorms north of a
line form Galena Summit to Island Park on Wednesday; and Thursday
further south to a Line from Hailey to Chesterfield
Reservoir.Afternoon temperatures cool to the middle 70s on those
days, and humidity mostly upper teens and lower 20 percent range.
Friday and Saturday will be mostly shower free under west-southwest
winds aloft. Then Sunday, a new disturbance is expected to form
near the coast and slowly move inland. Models have been rather
inconsistent with respect to any precipitation at this time. RS
