Marine Weather and Tide Forecast for Belfair, WA

SHORT TERM /TONIGHT THROUGH THURSDAY/
Dry and mostly sunny conditions dominate across western WA this afternoon as a ridge of high pressure noses into the region. Another cool night is expected overnight with areas of isolated fog and frost possible again. That said, temperatures are expected to be slightly higher, limiting the frost extent even more than this morning.

The ridge will shift east across the region Wednesday and Thursday allowing for a significant warm up. By Thursday, afternoon highs will reach into the low to mid 70s across the region.

LONG TERM /FRIDAY THROUGH TUESDAY/
By Friday, a trough off the coast will elongate and cluster analysis now slightly favors a cutoff low bringing the bulk of the energy south of the region Friday through Sunday and leaving western WA warmer and somewhat drier. Still there is a ~40% chance that the trough holds together and brings more of the energy our way leading to a wetter and cooler solution.

There remains a signal in ensemble guidance for weak and potentially transient ridging in the Monday/Tuesday timeframe next week. All in all, little impact is expected at this time.
