Marine Weather and Tide Forecast for Mountlake Terrace, WA

SHORT TERM /TODAY THROUGH WEDNESDAY/
The upper low that brought showers and mountain snow on Sunday has now shifted to our south, with dry northerly flow currently over western WA. Gusty NE Fraser River outflow winds will ease across western Whatcom and San Juan counties this afternoon. The focus now shifts to overnight lows as they will be quite chilly. With clear skies and lighter winds, Tuesday's lows will drop into the lower to mid 30s - mainly interior areas away from the sound. This will be the coolest of the season so far and a Frost Advisory is in effect.
Wednesday morning temps will also be cool but the flow will turn onshore during the day. Expect highs around 60 with clear skies otherwise. 33

LONG TERM /THURSDAY THROUGH SUNDAY/
Weak high pressure will nudge inland on Thursday but some warm frontal precip may clip the coast for a chance of light rain. A weak cold front will follow Thursday night but overall QPF is light with just a few hundredths. Showers will linger into Friday with ongoing onshore flow. A wetter Pacific storm system is slated to move inland this weekend (mainly on Sunday) for more rain, mountain snow, and locally windy conditions. 33

Small Craft northerlies will continue over the Puget Sound and over the outer coastal waters through the afternoon before easing this evening, as well as through the Eastern and Central Strait of Juan de Fuca through the early morning Tuesday. High pressure will build over area waters through Thursday, bringing light onshore flow and calmer conditions over the waters.
