Area forecast discussion 
National Weather Service Pocatello Idaho
213 PM MDT sun Aug 30 2015

Discussion...most of the precipitation associated with the trough
crossing northern Idaho tonight should remain north of this area.
Kept a slight chance of a shower in for a few hours this evening in
Custer County. Winds in the upper snake plain are expected to drop
off near sunset this evening. Both Monday and Tuesday are expected
to be dry under flat westerly flow pattern. Models have slowed the
development of the low pressure trough that develops middle week. There
will still be a dry cold front coming in Wednesday for a breezy day.
Another disturbance was expected on Friday but appears to be delayed
enough to keep southeastern Idaho in warm southerly air until
Saturday. High temperatures Friday were the single biggest change to
the current forecast. Receiver station


Aviation...southwest flow continues today...but more stable
conditions expected. Upper trough over central Washington may
produce showers/thunderstorms over central mountains but models keep
active weather north of ksun throughout the day. Thus expecting to
keep VFR conditions going through the period. Winds expected to be
gusty across the snake plain this afternoon/evening with strongest
winds at kida with gusts up to 30 kts. Hinsberger


Fire weather...upper trough is making its way across central Washington/or
with southwest flow ahead of it. Showers/isolated thunderstorms
development is possible over the central mountains and into Lemhi
County. A west/southwesterly flow will increase through the
afternoon as the trough approaches with some ridge-top wind gusts
near 35 miles per hour. Humidity is about 10 percent higher today on account of
the cooler airmass...but we may see downslope winds create low
humidity around the middle to upper teens in the valleys of fire zone
476 this afternoon. Not anticipating a red flag at this time...but
will closely monitor relative humidity trends through the afternoon. Monday will
generally be less breezy with no precipitation expected. Winds may pick up
again Tuesday afternoon across the central mountains along a weak
dry cold front...but the front will intensify on Wednesday as upper
level support provides reinforcement. Look for possible thunderstorm
development Wednesday afternoon/evening along with breezy
conditions. Hinsberger

Pih watches/warnings/advisories...none.
