Area Forecast Discussion
National Weather Service Pocatello ID
1043 AM MST Thu Feb 9 2017

.UPDATE...Model updates this morning were primarily focused on
adjusting forecast liquid precipitation amounts for the next 24
hours. Looking at trends last night and the 12Z model runs this
morning, the adjustments resulted in roughly a 20-30 percent
reduction, depending on location, over the previous forecast. A
good deal of the snow melt we have experienced lately is from
temperatures. Both temperature and new rainfall on existing snow
are important considerations when estimating how much water makes
it into local rivers. RS

&&

.PREV DISCUSSION... /issued 235 AM MST Thu Feb 9 2017/

SHORT TERM...Today through Saturday. Another storm system moving
into the Pac NW today will continue to spread rain and high
elevation snow across the area through tonight. Snow levels will
be pushing 8000 ft today...lowering tonight to around 7000 ft. The
heaviest snow is expected in the central mtns where an additional
6 to 12 inches is possible thru tonight. The upper Snake
Highlands may see an additional 3 to 6 inches above 7000 ft. The
main area of precip shifts to the southeast highlands on
Fri...while coverage and amounts decrease elsewhere. By Sat...most
of the precip is in the eastern highlands with fairly light
amounts. Temps will be a few degrees cooler Fri and Sat...but warm
enough to continue melting the low elevation snowpack. Hedges

LONG TERM...Sunday through Thursday...High pressure will be in
control of the weather pattern the latter half of the weekend and
going into early next week. This will allow for clear skies but
foggy mornings. Chilly temperatures are expected on Sunday as
northerly flow spills into the northern half of our region. Eastern
Magic Valley and the Southern Snake Plain areas are expected to
remain at near normal temperatures. Warmer conditions are expected
for all Monday and Tuesday with a further increasing temperature
trend Wednesday. Temperatures are then likely to settle as the next
weather system approaches from the west on Thursday with increasing
cloud cover and a chance for rain and snow showers is forecast.
NP/Hedges

AVIATION...Wind shear will be a concern at KSUN throughout the
day. Expect shear in the 30 to 35 kt range but it will not be
impossible for higher amounts of shear to be reached. MVFR ceilings
are forecast to drop to IFR this morning and remain down through
this evening. For KBYI, ceilings will be VFR but it may rain. Even
though we are not forecasting thunderstorms in this region in
particular, there is a slightly elevated concern here for downburst
potential should any convective activity develop nearby. Sounding
data is too favorable to ignore in the late morning to early
afternoon hours of this potential. Ceilings at KDIJ, KIDA and KPIH
are forecast to vary between IFR and MVFR today due to precipitation
activity once again. Winds are expected to be gusty this afternoon
to 30 kts. NP/Hedges

HYDROLOGY...Rain across the area today and tonight...combined
with warm temps will result in more snowmelt and continuing
flooding problems at lower elevations. Precip is expected to
diminish on Fri...but continued warm temps will prolong the
flooding threat for at least a few more days.
