.SHORT TERM...Today and Saturday
Early morning satellite imagery is void of any appreciable cloud
cover across eastern Idaho. Temperatures are chilly once again with
teens and 20s observed throughout the region. High pressure will
remain in control again today and into Saturday keeping things very
quiet around the region. Upper level northerly flow will wane today
becoming more southwesterly later this evening and especially into
the day on Saturday. This will allow temps to warm up somewhat today
but more so for Saturday when parts of the Snake Plain, Magic Valley
and valleys within the central mountains should climb in to the 50s
under ample sunshine. Winds will be light and skies will be mostly
clear of clouds today and again Saturday; although by later in
the day Saturday we`ll start to see an increase in clouds.

.LONG TERM...Sunday through Friday
It appears most of the moisture with Sunday`s storm will fall
across portions of the central mountains and eastern
highlands/Tetons. Highest elevations of the Sawtooths and Tetons
should see 0.10-0.20" of moisture, an inch or so in terms of snow
accumulations. Our next storm is still on track to impact us
Monday and Tuesday. There is some question about impacts lingering
into Wednesday. The latest GFS and ECMWF have the storm already
into the High Plains with northwest flow across Idaho. The
moisture train means we should see a decent amount of lingering
rain and snow especially across higher elevations. Only about 40%
of the clusters show the faster solution, with the rest still
having the low overhead by Tuesday evening. The latest forecast
spreads the moisture around a bit, but still favors the Sawtooths
and eastern highlands/Tetons. The latest forecast from WPC and
probability forecasts support 0.50-1.0" in those areas. There is a
20-30% chance of more than 1" of moisture across the Tetons, and
30-50% of more than that across portions of the Sawtooths. The
rest of central and eastern Idaho would see much lower amounts
especially with shadowing/downslope across portions of the Snake
Plain. More rain and snow is expected behind this low for the end
of next week. Temperatures should be near/just above average
Sunday and Monday, then drop quite a bit for Tuesday. We rebound a
bit for the latter half of next week. Keyes
