Area Forecast Discussion
National Weather Service Spokane WA
207 PM PDT Tue Apr 23 2024

.SYNOPSIS...
Mild and dry weather continues with 60s and 70s through Wednesday.
A subtle cooling trend arrives late Wednesday into Thursday with
breezy winds and increasing chances for rains. Unsettled weather
continues late through the weekend and early next week with better
chances for precipitation across the lowlands.

&&

.DISCUSSION...

Tonight through early Thursday: A weak Low will pass through Central
BC and push weak cold front through the region. With the zonal flow
pattern, precip associated with the front will mainly be confined to
the Cascades. The main concern with the front is the winds on
Wednesday. The winds will be in the upper teens and 20s MPH range
mainly in the Cascade Valleys and Waterville Plateau. Highs will dip
with cooler air mass and increased clouds. Highs will be in the
upper 50s to low 70s.

Late Thursday through Friday: The Low will breakdown the ridge and
allow for another Low to quickly move through the Pacific Northwest.
It is expected to bring a round of much needed showers to the Inland
Northwest with most areas with at least a 30% probability of at
least a tenth of an inch of precip. Higher terrains of the Cascades
and northern mountains could receive near a quarter of an inch. The
east slopes of the Cascades is expected to be impacted by the
rain shadow effect and should receive less. Increased cloud cover and
cooler airmass will lead to cooling trend for the rest the of
period. Thursday and Friday highs will in the mid 50s to 60s.
Overnight lows will be in the 30s and low 40s.

Saturday through Tuesday: Models are keeping the region in a cooler,
wet pattern as a strong Low slowly moves through the Gulf of Alaska.
The region can expect periods of mountain snow for the Cascades and
rain showers for the rest of the Inland Northwest. Highs will
continue to be in the mid 50s and 60s. OVernight lows will generally
be in the 30s and low 40s. Some areas in the northern valleys could
see upper 20s. /JDC

from the west and thicken through Tuesday afternoon. Winds this
afternoon will be light, but will become breezier on Wednesday
