Area Forecast Discussion
National Weather Service Spokane WA
350 PM PDT Mon Apr 15 2024

.SYNOPSIS...
A cold front will bring a return of cooler and showery weather
early this week. The front will bring breezy conditions tonight
through Monday. Warmer, dry weather is expect to return later this
week.

&&

.DISCUSSION...
Tonight and Tuesday: The cold front will exit the region. It will
usher in colder air and declining winds behind it. Snow levels
are expected to drop to near surface. Overnight lows will be in
the upper 20s and 30s. While the snow levels drop, the cold air
will be accompanied dry air. Most locations are expecting a precip
free period. Stevens Pass is expected to have snow overnight with
a 60% probability of at least 4 inches. Surface temps will make
it hard for accumulation on the roadways. Outside of the Cascades,
the shower activity is expected to be in the higher terrain along
the Canadian Border. Amounts will be light with little to no
accumulation expected. Winds will be weaker but still be breezy
with sustained in the teens and gusts in the 20 mph range. Tuesday
highs will be lower than Mondays. Highs will be in the upper 40s
and 50s. /JDC

Wednesday through Monday: Chances for showers and daytime temps
slightly below daily normals are expected Wednesday as a weather
disturbance drops southward across the Inland Northwest. The best
precip chances will be across NE WA and N ID. Conditions look to dry
out for Thursday and Friday. Though not with strong consensus,
several extended range models indicate a trough pushing though over
the weekend, with precip chances returning to the forecast Saturday
night and Sunday. Through the entire extended range forecast, temps
do not appear likely to stray very far from seasonal norms. /KD

.AVIATION...
00Z TAFS: Winds will continue to be breezy through the afternoon
with gusts into the 30s and low 40s. VFR conditions are expected
through the period. Localized visibility reductions due to blowing
dust from recently worked fields will be possible around Moses
Lake through 02z. Winds will calm slightly overnight into the
teens. Winds are expected to increase in during the daytime as
stronger low level winds mix down to the surface but be lower than
winds on Monday.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
Forecasting visibility reductions due to blowing dusts is a low
confidence endeavor due to the many variables involved. Soil
conditions and ag activity are a few variables.

-----------------------

Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
