Area Forecast Discussion
National Weather Service Spokane WA
1006 PM PDT Sat Jun 22 2024

.SYNOPSIS...
A dry cold front on Sunday will create elevated to critical fire
weather concerns over portions of central and eastern Washington
with widespread breezy to windy conditions. This will likely be
followed by temperatures cooling back down towards normal values
by Monday. Another warm up arrives on Tuesday and Wednesday before
the next weather system arrives on Thursday.

.DISCUSSION...

Evening update: The Red Flag Warning has been expanded into the
Wenatchee, Chelan, and Waterville areas as well as the Okanogan
Valley for Sunday afternoon and evening. While the relative humidity
Sunday afternoon may be marginal for Red Flag criteria (20
percent or less) around Wenatchee and Waterville, sustained winds
of 15 to 20 mph will begin by 10 or 11 am and increase to 20 to 25
mph with gusts to 40 mph by 3 pm. The duration of the wind,
magnitude of the gusts, and recent dryness tipped the scales to
adding these areas to the Red Flag Warning. /GKoch
