Marine Weather and Tide Forecast for Ocean City, WA

SHORT TERM /TONIGHT THROUGH SUNDAY/
Not much to add this evening regarding the upcoming change in the weather. Shower coverage will increase through the day on Friday. Models continue to lock into the idea of the most widespread precip coverage being early on Saturday as moisture wraps around the departing upper low. Sunday will be a transition day as temperatures rebound and drier conditions return.
Summer in its recent familiar form returns for Monday and Tuesday.
Conditions are still slated to cool down a bit for the later half of next week, but the jury is still out on how significant of a cooling trend it will be. Previous discussion follows with updates to marine aviation portions. 27
