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 && .AVIATION...-- Changed Discussion --06z TAFS: A dry cold front will move through central Washington tonight and into eastern Washington and north Idaho by early Sunday morning.
