.KEY MESSAGES...
- Cooler and locally breezy Thursday
- Warmer again with above normal temperatures this weekend and
into next week
&&
.SYNOPSIS...
After a brief cool down on Thursday, warm temperatures will
return over the weekend into next week. Winds will also be
locally breezy at times on Thursday headinto into this weekend
especially in Central Washington.
&&
.DISCUSSION...
Evening update: The Red Flag Warnings were allowed to expire at
8 PM PDT this evening. Winds are on the gradual decline along
with increasing relative humidity across the region. JW
&&
.AVIATION...
06Z TAFS: VFR conditions are expected to continue for all TAF
sites through 06z Friday. A weak weather system passing north
and east of the area on Thursday will bring a 20% chance of a
rain shower to the North Idaho Panhandle otherwise dry
conditions are expected. This will also bring about a wind
shift, from west- southwest tonight to north-northwest heading
into Thursday afternoon and evening. Winds will also be locally
breezy on Thursday, with gusts of 15-20 kts, except 25 kts at
KEAT.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence
that VFR conditions will continue at all TAF sites. The Hope
and Western Pines Fires over NE Washington could advect some
smoke into the Spokane/Coeur d`Alene area late Thursday
afternoon into the evening with the northwest wind shift.
But given decreased heat on satellite tonight, and that the
smoke would more likely be aloft, surface visibility is not
expected to remain above 6 miles. JW
-----------------------
Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
