National Weather Service Pocatello ID
344 AM MDT MON SEP 5 2016

.Discussion...Today through next Monday. Today look for lingering
isolated showers and thunderstorms with light high mountain snow
mainly over the Central mountains and the Upper Snake Highlands
from an exiting upper level low system. Temperatures will remain
well be normal today and continue into Tuesday. A frost advisory
has been issued for Tuesday from 3 am to 9 am for the Snake River
plain.

Expect a rather mild remainder of the week with below normal
temperatures. A weak system will move through late Tuesday into
Wednesday morning bringing breezy winds with isolated showers over
the Northern Central mountains. Another weak system moves through
on Thursday continuing the breezy winds.

For the weekend...the models have now changed. Instead of
building in high pressure with warmer temperatures...the models
are now showing an upper level low dropping over our Eastern areas
late Sunday into Monday bringing back precipitation chances and
much cooler temperatures. Wyatt
