Area Forecast Discussion
National Weather Service Spokane WA
1134 AM PDT Thu Jun 27 2024

.SYNOPSIS...
A passing cold front continues to bring showers and
thunderstorms through Thursday. Mild and dry weather is likely for
Friday followed by heat Saturday. The next system will move
through on Sunday with more wind and thunderstorms. Mountain
showers and seasonal temperatures will continue through the early
week. Temperatures look to trend warmer and drier by the middle to
the end of next week.

&&

.DISCUSSION...
Today through Friday night: The upper level trough will continue to
slide through the region. The chance of thunderstorms expands on
Thursday to Eastern WA and the ID Panhandle, with lightning being
the main concern. The timing of these storms looks to start late
morning, continuing through the afternoon as they move east. Breezy
winds will continue through the morning with increasing speeds into
the afternoons. Gusts of 30 to 40 mph will be common across the
Columbia Basin extending east towards Spokane and the Palouse.
Humidity will be higher which will decrease the threat of fire
concerns. Temperatures will be cooler today, with highs in the 70s.

A ridge move in behind todays system, leading to a mild, dry Friday.
A few lingering showers are expected over North Idaho through the
morning. Highs will be in the upper 70s and 80s. Lows will be in the
50s. /KM

Saturday through Thursday: Saturday will be mostly dry and mild
thanks to a shortwave ridge. There is a small chance (20%) of
showers at the Cascade crest and Okanogan Highlands Saturday
afternoon thanks to deep moist southwest flow. Temperatures will be
in the 80s to low 90s.

Thunderstorm chances increase Sunday as a trough comes ashore. The
moist system will need to be monitored to flash flooding potential,
especially vulnerable burn scars. Winds behind the front passage
will be breezy Sunday evening, but fire risk should be reduced
thanks to the moist nature of this system. Precipitation chances
stick around through late next week as the progressive pattern
continues.

.AVIATION...
18Z TAFS: Breezy westerly winds will continue through the
afternoon with gusts between 20-30 kts, with better mixing
potential in the afternoon. Scattered showers and embedded
thunderstorms will increase through the early afternoon for
Northeast Washington and North Idaho and reaching into the
Spokane and Pullman areas. Impacts possible are heavy rain,
lightning, and small hail.


FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
High confidence in VFR conditions through the TAF period. There is
a moderate chance for thunderstorms across the Spokane/Coeur
d`Alene corridor in the afternoon. These areas could experience
brief periods of MVFR conditions with ceilings under 3000ft. /JDC
