.DISCUSSION...Rain and snow showers will continue into this
afternoon as a trough continues to move through Idaho and western
Montana. Showers will decrease by this evening and skies will
begin to clear once the system moves off to the east. Decreased
cloud cover tonight will result in a combination of patchy fog and
cool Monday morning temperatures. Places that end up with clear
skies and without fog will fall below freezing with low
temperatures in the upper 20s. Spots that have had precipitation
today are more likely to see patchy fog so temperatures may not
drop quite as low.

High pressure Monday into Tuesday will produce very nice spring
days with above average high temperatures and sunshine. Tuesday
still looks like the warmest day, with many valley locations
expected to reach into the mid to upper 70s!

Wednesday will bring a change in the weather as an upper level
trough of low pressure and associated cold front will move through
the region. This will result in cooler temperatures, increased
clouds, showers and breezy winds.

Forecast models have been inconsistent in the timing of weather
systems beyond Thursday. But the overall pattern through Sunday looks
like a typical spring pattern with a few showery/breezy days and
high temperatures around the 60s.

.AVIATION...Cloud cover remains through much of north central
Idaho and western Montana this afternoon as a weather system
begins to exit the region. Rain and snow are still common along
the divide and showers are quickly developing in western Montana.
High resolution model guidance agree that precipitation will
decrease late this afternoon as well as cloud cover from west to
east. Clearing skies overnight along with precipitation from the
day will allow for patchy fog to develop in many of the valley of
north central Idaho and western Montana Monday morning. After fog
dissipates mid-Monday morning high pressure will result in mostly
sunny skies and light winds.
