Area Forecast Discussion
National Weather Service Pocatello ID
130 PM MDT Tue Oct 31 2017

.SHORT TERM...Tonight through Thursday Night.

A low pressure system will drop out of Canada into the northern
Plains tonight. We are beginning to see moisture associated with
this system filtering into the region from the north. Meanwhile a
shortwave trough extends west from this system through British
Columbia. Winds ahead of this trough are increasing across the
region and we expect to see winds remain up through the night.
Expect strong winds for Wednesday afternoon ahead of this trough.
Sustained 25 mph with gusts to 50 mph are likely across the eastern
Magic Valley into the south and east highlands. We are also seeing
potential for stronger winds across the Snake Plain where sustained
30 to 35 mph with gusts of between 55 and 60 mph. Will issue wind
advisories and high wind watches for these areas accordingly. From
Mackay to Challis we expect winds near advisory levels, but will
hold off an advisory for that region for now. This trough will pass
through eastern Idaho Wednesday night. Deeper moisture will work
into the region from the north and we could see some light
precipitation across the central Idaho mountains into the upper
Snake highlands Wednesday night into Thursday. Snow levels will be
generally above 6000 feet but amounts look light, with snow amounts
less than an inch. If we can get enough clearing, there's some
indication that we may see wind advisory levels once again Thursday
afternoon across portions of the Snake Plain. By the time we get to
Thursday night, a strong low pressure system will have set up near
Seattle. This low will tap into Pacific moisture and direct this
moisture towards central and east Idaho. Expect to see precipitation
increase throughout the night. Snow levels with this initial surge
of moisture will start off high, generally near or above 7000 feet.

Valle

.LONG TERM...Friday through Tuesday...Main feature for the long-
term periods will be a broad upper trough that develops along the
Pacific Coast. Moisture embedded in the resulting southwesterly
flow will spread across southeast Idaho heading into the weekend.
A warm front may drive some of the precip northward around mid-day
Saturday, but a cold front will drive across the region Saturday
evening, resulting in areas of enhanced precip, strong winds, and
cooler temperatures. We may see a bit of a break after the cold
front passes early Sunday morning. The Pacific trough gets some
reinforcing energy from a second shortwave Saturday night. This
trough will then come into phase with an upper low that develops
off the California coast, which lifts across the Great Basin
Monday night into Tuesday, further enhancing precip along our
southern border. Variations among ensemble members lessen the
certainty of a dry forecast for Tuesday, particularly over the
Central Mountains. Have thus added some slight chance PoPs for
that area. Hinsberger

&&

.AVIATION...High clouds drifting in from the north ahead of a
shortwave still located in Central BC/Alberta. This shortwave energy
will be the primary driver of weather through much of the TAF period
as it drops into Idaho tomorrow morning. Winds are a primary concern
with gusts to 25kts today, and approaching 40kts late tomorrow
morning as the near-surface layer mixes out. Blowing dust will be a
concern tomorrow, but keeping VFR conditions in the terminals.
