.DISCUSSION...
Issued at 213 AM MST Fri Mar 6 2026

The upper trough axis is now shifting through UT/CO/WY with Idaho on
the periphery of an area of high pressure as we head into the
weekend, resulting in a transition to drier and warmer conditions.
Light snow showers will continue across the eastern mountains
through the afternoon, bringing another inch or two of snow to these
areas. Area observations indicate wind gusts still in the range of
25 to 30 mph early this morning across the South Hills and foothills
of the Beaverhead and Lost River mountains. Breezy winds will
persist in these areas and return elsewhere this afternoon before
becoming much lighter Saturday. Temperatures will gradually warm
today and Saturday, but northerly flow aloft will keep temperatures
only slightly above seasonal norms. Northerly flow will also
continue to usher in enough moisture to perhaps support some very
light snow showers in the high terrain during the weekend timeframe
but will ultimately remain inconsequential. Flow aloft will turn
zonal come Sunday, allowing temperatures to drastically warm into
the 50s and low 60s across the lower elevations for much of the
week. Weak disturbances will bring chances for more light, showery
precipitation mainly for the central and eastern mid to high
elevations throughout the week. The zonal regime will also lend to
breezy surface winds for the entirety of the week with winds
becoming near-advisory to advisory-level.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 827 PM MST Thu Mar 5 2026

A weakening upper level low over western Wyoming is bringing
lingering light showers to DIJ which is causing IFR/LIFR
conditions. These showers should end around 6Z though some
guidance suggests showers and MVFR/IFR conditions until around
12z. Weak high pressure will build in from the west this evening
into tomorrow. Once the showers have moved east in the next
couple of hours, VFR conditions are expected for all TAF sites.
Fog with MVFR/IFR VIS and CIGS is possible this evening but is
not that likely with cloud cover and slightly breezy winds. IDA
and DIJ have the best chance of winds dropping off and fog
development. But, fog development chances are low, 10 to 20%.
Clouds will gradually start clearing out by late tomorrow
morning into tomorrow afternoon. Expect wind gusts of 20 kts for
BYI, PIH and IDA tomorrow afternoon. Winds will drop off by
early evening with clear to mostly clear skies.
