Satellite imageries show a ridge lingering over the area, holding a trough to the west and south, and a shortwave trough to the east-northeast. Open-cell cumuli clouds associated with the ridge continues to move across the territory, increasing the potential for passing showers. This is also reflected on the upper air observations (RAOB) from this afternoon (11/00Z)-stable atmospheric profile with a gentle east-northeast breeze. Models are suggesting the ridge to remain over the area through at least late Tuesday. Thus, scattered showers with a gentle east breeze is expected for this time frame. By midweek, models are showing the aforementioned shortwave trough moving over the area. This feature will likely increase the potential for showers and possible thunderstorms over the coverage area. Once the trough passes the area on late Thursday, a high pressure system to the southeast will produce a gentle to moderate easterly flow with embedded showers over the area. Therefore, expect numerous showers with a gentle east breeze for the rest of the forecast period. && .Marine... The latest PacIOOS buoy observations show seas around 4 to 6 feet. Model data show these heights remaining in the area throughout this forecast period. A light to gentle breeze with an intermittent moderate easterly breeze from time to time will prevail for this week. No other significant swell is expected for this week. && .PPG WATCHES/WARNINGS/ADVISORIES... NONE && $$ JTAllen
