.SHORT TERM...Today and Sunday
Early morning satellite imagery is again void of any appreciable
cloud cover across eastern Idaho. To our west, do see some mid/high
level clouds across central and eastern Oregon that will eventually
move our way later this afternoon but for the first half of the day,
skies will again remain clear. Upper level flow will become more
southwesterly later today and temps will warm around 5 up degrees
from their Friday highs across the Magic Valley and Snake Plain.
This should bring daytime highs up into the 50s today in the
aforementioned areas with 40s lingering across the upper Snake and
into the eastern highlands. Winds will remain light and skies will
be mostly clear early but clouds will gradually begin increasing
from west to east later this evening with mostly cloudy skies likely
by daybreak on Sunday. Will likely see some high elevation precip
(mainly snow) but a little rain/snow mix could occur in the lowest
of elevations across the central mountains, eastern highlands and
around Island Park on Sunday. Any precip should be pretty low impact
however has QPF totals are just a few hundredths at best so not
anticipating anything of significance. McKaughan

.LONG TERM...Monday through Saturday
Trends show things slowing down a bit on Monday, with most of the
precipitation arriving later in the afternoon for the central
mountains, then impacting the rest of eastern Idaho Monday night
and Tuesday. At the moment, not much rain and snow is expected
outside of the Sawtooths and eastern highlands/Tetons. We could
see 0.25-0.35" for higher elevations of the Albion Mountains and
southeast highlands through Tuesday night. For the eastern
highlands, the latest forecast has around 0.33" to just over 0.75"
for the Tetons. There is a 40-50% chance of exceeding 0.75" and
15-25% chance of more than 1". For the Sawtooths, the latest
forecast has 0.50-1.0" of moisture falling...with a 15-25% chance
of exceeding 1". Looking at snowfall, we could see some light snow
showers across the Snake Plain and Magic Valley but anything
accumulation-wise or impact- wise looks minimal. Up to 4" looks
common for many mountain ranges outside of the Sawtooths and the
eastern highlands/Tetons. 4-10" in those areas is possible with
locally higher amounts. We do expect these totals to change over
the next 24-48 hours, so certainly make sure you keep track of the
forecast through the weekend. We should see a lull in rain and
snow Wednesday before things pick back up for the latter half of
next week. Keyes

.AVIATION...
VFR conditions expected through the period. Skies will be clear to
mostly clear with early with light and variable winds everywhere
except KSUN where the usual upvalley/downvalley flow will be
present. Clouds will begin to increase later this afternoon around
KSUN and then overspread the rest of the area into the day Sunday.
CIGs will remain high though allowing for VFR to continue but we
definitely transition to more clouds than sun as we get into Sunday.
Any precip Sunday should be focused around the higher terrain so
KSUN and KDIJ will likely see VCSH mention for subsequent
forecasts. McKaughan
