.SHORT TERM /Through Thursday Night/...
Issued 138 PM MST TUE NOV 3 2026
High clouds will continue to increase through the afternoon, as
a low moves eastward across northern Nevada (currently over
northern California). While most of the area area will remain
dry overnight, portions of southwestern Idaho near the Nevada
border will get into the wrap around portion of the low, with
isolated to scattered showers. Snow levels will be around 6-7kft
MSL, although little if any accumulation is anticipated in
regard to both liquid and frozen precipitation. Temperatures
this afternoon will warm to be around 60 degrees in lower
elevations, and 50s in the Oregon high desert and mountain
valleys. Breezy west/southwest winds will also set in, strongest
in the typical windy portions of the Snake River Plain with
gusts to 20-30 mph. Gusts will taper off this evening with light
winds overnight.

A brief period of ridging will bring clearing skies and lighter
winds Wednesday, with high temperatures similar to that of today
if not a degree or two warmer. This ridge will be short-lived,
however as a short-wave and it`s associated cold front will
break it down and cross over our area Thursday. This will allow
for slightly cooler temperatures (although seasonable for the
time of year). While moisture looks to be rather limited with
this front, it will serve as the focus for increased
precipitation chances, 20-40% chance mainly in our northern
zones, as it passes through from west to north. Precipitation
chances will taper off quickly behind the front with northwest
winds of 5-10 mph with gusts up to 20 mph in open terrain.

.LONG TERM /Friday through Tuesday/...
Issued 138 PM MST TUE NOV 3 2026
Troughing moving onto the coast of British Columbia on Friday,
paired with a building ridge over California, will shunt the
majority of tropical moisture coming in on an atmospheric river
to the north. This flow will keep our area dry throughout much
of the period. Periodic short-waves will work to break down the
ridge beginning early next week, but with much of the moisture
wrung out in the Cascades, the only tangible evidence would be
increased mid-high cloud cover. Uncertainty in pattern evolution
increases come Tuesday, although cluster analysis favors the
pattern persisting.
