Area Forecast Discussion
National Weather Service Spokane WA
449 AM PDT Mon Jul 1 2024

.SYNOPSIS...
Mountain showers, seasonal temperatures, and breezy winds will
recur through Wednesday. A drier and much warmer pattern will set
up by the end of the work week.

&&

.DISCUSSION...
Today through Wednesday: Daily terrain based shower and
thunderstorms continue but the areal coverage decreases day over
day in the Inland Northwest. Another weak 500 mb shortwave just
off the coast of WA will assist the formation of showers and
thunderstorms in the northern mountains later this morning and
into the afternoon. Models suggest the best chance for
thunderstorms are along and north of highway 20 near the WA/ID
border (40% chance). Again, thunderstorms will be capable of brief
heavy rain, small hail, and gusty winds. Yet another shortwave
riding on top of a strong ridge forming over the Pacific will
bring additional shower and thunderstorm chances to northeastern
Washington and north Idaho Tuesday and Wednesday (20% chance).
Temperatures through Wednesday will be in the 70s and 80s. Winds
will also be breezy especially in the Cascade gaps gusting up to
30 mph in the evening hours. /butler

Thursday through Sunday: A building high pressure ridge will take
shape across the northwestern U.S. late in the week. This will
lead to dry and warming conditions for Independence Day into the
weekend. Afternoon highs for Friday and the weekend are forecast
to run about 10+ degrees above normal. Winds will be rather light
for most locations, with gusts generally remaining below 20 mph.

.AVIATION...
12Z TAFS: KSFF will experience patchy dense fog for the next few
hours. Otherwise expect VFR conditions with breezy winds this
afternoon. Thunderstorm acitvity later will be northeast of
Spokane (20-04z).

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in
VFR conditions. Low confidence in timing for improvement for KSFF.
