083 FXUS66 KSEW 162134 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 234 PM PDT Fri Apr 16 2021 .SYNOPSIS...Dry and warm conditions continue across the region into the weekend as upper level high pressure remains in place. Slight cooling arrives at the coast Sunday with a return of cooler onshore flow. Dry and mild weather will follow through mid week. && .SHORT TERM /TONIGHT THROUGH MONDAY/...Warm and dry weather will continue through the weekend with high pressure over the region. Temperatures are mostly in the 70s this afternoon with a few low 80s as well. Temperatures will peak on Saturday and will be a few degrees warmer compared to what we are seeing today. Temperatures will then nudge downwards a few degrees on Sunday (although still remain above average) as the thermal trough weakens and the flow flips onshore. The interior will still see highs in the 70s but cooler NW flow will keep the coast in the 60s. The flow turns offshore again on Monday while a frontal systems slides south through eastern WA. This will bring breezy NE/E winds to western Whatcom county and the Cascade gaps. Expect highs in the 60s along the coast with lower 70s inland. Fire Weather concerns remain elevated through the weekend due to warm and dry conditions (and low humidity). Finer fuels, like 100-hour fuels, are seeing record dryness for the season under these current conditions. The fire danger is lower in the mountains where the snowpack remains healthy. 33 .LONG TERM /TUESDAY THROUGH FRIDAY/...Western WA remains under weak high pressure through mid week for more dry and mild weather.
