...RED FLAG WARNING IN EFFECT FOR HOT, DRY, AND UNSTABLE CONDITIONS

.DISCUSSION...Hot and dry conditions continue through this weekend.
Highs in the 80s and 90s with minimum RHs form 15-30% are expected
across much of the mountains and the lowlands south of Puget Sound.
Overnight RH recoveries will be poor to moderate due to offshore flow.
Increasing instability going into the weekend will lead to critical
fire weather conditions through the weekend over the mountains with
elevated conditions across the lowlands south of Puget Sound. These
conditions look to persist into next week as temperatures/humidity
slowly moderates throughout the week.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
