Marine Weather and Tide Forecast for Boulevard Park, WA

SHORT TERM /TODAY THROUGH WEDNESDAY/
A dissipating frontal system will bring about light rain for much of the area through this afternoon. Rain amounts are going to be light, anywhere from around a tenth of an inch within the Puget Sound region to three quarters of an inch in the mountains. High resolution guidance is suggesting some weak convergence zone activity this evening along the King and Snohomish county line. Temperatures will retreat back into the mid to upper 50s.

High pressure will build back in through the middle of the week.
With light winds expected and grounds still moistened from recent precipitation, patchy fog will be possible Tuesday morning and potentially again on Wednesday. Dry conditions are expected throughout the day on Tuesday, with light rain filling in Wednesday morning as the next system arrives.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
The forecast is still showing a more active pattern taking over in the later half of the week and into the weekend. The precipitation on Wednesday is not looking particularly impressive, yet there are still details to be resolved in regard to the track of the associated low pressure system. The ensemble cluster analysis shows a trough parked over the west coast broadly, but there are some variations in whether the trough moves inland via California or nudges more north into the Pacific Northwest. This will have implications on the amount of precipitation received, but will continue to monitor for consensus on a solution in the coming forecasts.
