Area Forecast Discussion
National Weather Service Boise ID
334 AM MST Fri Nov 14 2025

.SHORT TERM...Today through Sunday night...An upper level trough
is splitting off from the parent flow into southern CA later
today. The northern portion of the system is bringing scattered
showers to the area this morning. Showers will taper off later
this morning with clearing by the afternoon, as the main jet
stream lifts northward and the cutoff low remains near southern
CA. Temperatures will remain mild with highs around 10-15
degrees above normal through Saturday. Temperatures in the
Snake Plain will be in the low to mid 60s today and again on
Saturday. The upper level trough over southern CA will move
northward into the Great Basin on Sunday, with showers likely by
Sunday afternoon. Snow levels remain around 7000-8000` with this
system.

.LONG TERM...Monday through Friday...Forecast confidence is low
in the extended period. Quite a change in the extended period
with the models from previous runs. The latest projections
weaken the trough over the Great Basin and bring another system
down the West Coast into another cutoff low off the CA coast by
Tuesday and Wednesday. This would bring drier and warmer
conditions Tuesday through Thursday with upper level ridging
over southwest ID and southeast OR. With this new solution,
high temperatures could be 5-10 degrees warmer than the current
forecast.
