Area Forecast Discussion
National Weather Service Spokane WA
931 PM PDT Mon Mar 18 2024

.SYNOPSIS...
High pressure will slowly break down early this week bringing
warm and dry conditions through Tuesday. Over the second half of
the week, temperatures will cool and chances of lowland rain and
mountain snow will return through the weekend.

&&

.DISCUSSION...
Today through Wednesday: Ridging will slowly weaken the next couple
days but we remain warm and dry today and tomorrow. Orographic
ascent from west flow increases precipitation chances Wednesday in
the Cascades and Panhandle. Snow levels ranging from 4500-6000 feet
Wednesday will lead to minimal impacts.

Thursday through Monday:
Snow chances increase in the mountains Thursday as a shortwave
approaches from Oregon. Snow levels start around 4500 feet but
warming daytime temperatures Thursday minimize snow impacts again in
the mountain passes. Even into Friday impacts appear minimal. A
backdoor cold front coming from the northeast will bring cooler air
to support snow first at Lookout Pass and the Northern panhandle
lowlands Friday night into Saturday and eventually the Cascade
passes into Saturday. Continual cold air advection may bring snow as
far southwest as Spokane Sunday. Additional chances for rain and
snow reach into the beginning of next week.

Chance of 4" or more/8" or more/12" or more Fri-Mon:
Stevens - 65%/25%/0%
Lookout - 85%/65%/40%
Sherman - 55%/20%/0%

Chance of 1" or more/2" or more/4" or more Fri-Mon:
Spokane - 40%/25%/10%
Lewiston - 0% for all
Pullman - 10%/0%/0%
Wenatchee- 0% for all
Sandpoint - 75%/67%/45%
