National Weather Service Pocatello Idaho
635 am MDT Sat Mar 28 2015

Short term...today through Monday night. Cold front is on schedule
to pass during the daytime hours today...making the temperature
forecast difficult as temperatures will likely cool some during
the early afternoon. Not much moisture or cloudiness expected with
this...especially the farther south you are in the forecast area.
There is some instability...but with very limited moisture...on
the order of 0.25 to 0.40 inch of precipitable water. The no-
brainer for this front is the very windy conditions expected to be
brought to the Snake River Plain and the valleys in the south
Central Highlands. Southwest to west wind should peak around 1100
to 1400. Main focus is the Interstate 15/86/84 corridors...but
even the Arco desert and parts of the north side of the plain
should see some wind. Have added blowing dust trouble to the
grids. However...the term patchy blowing dust sounds strange and
kept it as areas instead...which may be a slight over-forecast.
The trough and front should be out of Idaho by early
evening...with breezy conditions left in its wake and temperatures
cooler. Skies clear rapidly and winds decrease substantially to
allow strong warming...though not back to near record warmth until
Monday. Messick

Long term...Tuesday through Saturday night. A strong upper trough
moving into the Pacific northwest on Tuesday will bring snow to the central mountains
Tuesday morning...and spreading to the eastern Highlands by Tuesday afternoon.
Precipitation will mainly impact the northern parts of the forecast area...but
the fast movement of the system will limit precipitation amounts. The Snake
River Plain and southern Highlands are expected to remain dry.
Strong winds are expected on Tuesday with a cold front passage. A few
snow showers will linger through Wednesday over the central mountains and upper
snake Highlands. A minor upper trough quickly follows the previous
system Wednesday night...with precipitation becoming more widespread on Thursday.
Broad ridging moves in for Friday...with the European model (ecmwf) being more amplified
than the GFS. A deep upper trough approaches the Pacific northwest coast late
Sat. This results in increasing SW flow...and increased chances for
mountain precipitation. Temperatures will remain cool through the end of the week...with a
little recovery by Sat. Hedges

Aviation...a cold front moving through the area today will bring
strong SW winds to the Snake River Plain today...diminishing
tonight. A few rain/snow showers are possible in the central
mountains...but not expected to have any sig impact on ksun. VFR
conditions will prevail. Hedges
