Marine Weather and Tide Forecast for Neah Bay, WA

SHORT TERM /TODAY THROUGH MONDAY/
Surface high pressure over W WA leading to mostly calm winds observed so far this morning. As a result, patchy morning fog is developing with most of the coverage expected over the Chehalis River valley. For today, we'll begin to see pattern progression as an upper low well offshore gently tracks eastward. The aforementioned low center is becoming ingested into the mean- flow before looming just off the CA/OR coast on Sunday with upper-level ridging over the Gulf of Alaska. Slight PoPs may sneak their way into SW WA on Sunday however, conditions are slated to remain mostly dry and trend that way into Monday as the ridge axis begins to position overhead. High temperatures are to top out in the upper 40s to near 50 F with overnight lows cooling into the 30s each night.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
An upper-ridge continues over the PNW on Monday night. The next front looks to arrive by Tuesday evening with a chance of widespread lowland rain and mountain snow. Afterwards, conditions are forecast to remain active into Friday. At this time, the potential for significant weather hazards appears low and the precipitation looks primarily beneficial for the region, adding some much needed snow to the snowpack in the mountains.
That said, given a weak favoring of above normal temperatures, snow levels may limit the overall additions.
