UPDATE
A convergence zone lacked enough moisture to form showers this evening, ending the last chance for precipitation for the next few days. Low stratus will develop across portions of the Puget Sound and along the coast early this morning, though likely not as extensively as last night. Conditions will improve as the sun comes up, leading to a mostly sunny and mild afternoon across western Washington. No updates this evening.
SYNOPSIS
Building high pressure will allow for temperatures to rebound upward Tuesday and Wednesday. Weak systems will bring temperatures back down by Friday into the weekend and may bring with them chances for precipitation across the region.
SHORT TERM /TONIGHT THROUGH FRIDAY/
Upper level ridging will nose into the region Tuesday and build through Wednesday allowing for temperatures to rebound up both days. Slight cooling is expected Thursday as a wave flattens the ridge. HeatRisk levels will remain in the green and yellow categories through the period.
LONG TERM /SATURDAY THROUGH TUESDAY/
Forecast confidence wanes somewhat Friday through the weekend as ensemble guidance continues to struggle with the synoptic flow. The general consensus is for additional waves to move through the area keeping temperatures mild and precipitation chances in the forecast. That said, even at the extremes of the ensemble envelope there doesn't currently appear to be a signal for any significant weather hazards during the extended period. -Wolcott-
AVIATION
Mostly low end VFR with areas of MVFR behind the passage of a cold front. Mid level ceilings are anticipated to lower during the early morning hours of Tuesday with a low probability of ceilings getting below MVFR for most inland areas.
Ceilings will improve throughout the late morning Tuesday as high pressure builds into the region. Onshore flow will continue with north/northwest flow with breezy winds at KHQM/KCLM/KBLI generally lessening this evening to 8 kt or less overnight.
KSEA...Low end VFR with northeast surface winds 10-13 kt decreasing into the evening to 8 kt or less. Ceilings hold a low chance (20% to 30%) of lowering to MVFR 2000-2500 ft between 08z-15z Tues, so left as SCT for now. Ceilings will scatter out by the late morning with dry conditions and north/northeast surface winds 10 kt or less Tuesday.
AL
MARINE
Gusty SCA winds behind the passing of an upper level trough in the Central/East Strait of Juan de Fuca and the Admiralty Inlet will continue through the late evening. High pressure will build off the coast during the week, with troughing to the east. Strong northwesterlies will translate downward towards the surface, so a couple periods of gusty winds are possible in the outer coastal waters Tuesday evening into Wednesday, as well as the central Strait of Juan de Fuca. A stronger push looks probable Wednesday into Thursday for these areas, and again Friday for the coast.
Seas will hold around 6 to 8 ft through Friday before increasing 8 to 12 ft from Friday into the weekend.
