.DISCUSSION...Showers have ended across the area this evening in
the wake of today`s cold frontal passage. We expect the remainder
of the night to be dry, so we will remove the small chance of
precip in the northern mountains. No other changes will be made at
this time. Update out momentarily.


.AVIATION...Mostly VFR, with areas of MVFR in the mountains.
Mountains will be obscured at times. Surface winds: variable less
than 10 kt. Winds aloft at 10k ft MSL: SW to W 20-40 kt.


SHORT TERM...Tonight through Monday night...The cold front has
moved through the forecast area. Strong winds accompanied the
front as it moved through, with pockets of stronger wind lingering
over the Western Magic Valley this afternoon. Post-frontal showers
also continue to impact the area. Precipitation and wind activity
will weaken this evening with drier southwest flow moving over
the area. Mostly dry conditions and slightly warmer temperatures
expected on Sunday, which is expected to be a brief break from
activity. Low pressure moving south along the western coast will
send moisture over the forecast area on Monday, bringing a return
of mountain snow and valley rain, which will linger into the
evening hours. Temperatures will cool slightly on Monday, with
values near or slightly below normals.

LONG TERM...Tuesday through Saturday...Remnant moisture from a
nearby low pressure system will keep isolated showers over the area
for Tuesday/Wednesday. This low is expected to head southward along
the west coast and bring in cooler than normal temperatures for
Tuesday. This low will then continue to head south and eastward
Wednesday and Thursday, resulting in a drying and warming trend as
high pressure builds into the area. Temperatures should be near to
slightly above normal for Wednesday through Saturday. Latest model
runs indicate the return of showery conditions for late next
