Marine Weather and Tide Forecast for Lemon Hill, CA

DISCUSSION

...Today - This Weekend... Current GOES-West imagery shows a broad stratus deck continuing to cover the Delta, Valley, and adjacent lower foothills this afternoon. This cloud coverage has kept temperatures quite cool in those areas today, 10-15 degrees below normal for this time of year, while higher elevations have been sunny and mild. The low clouds also greatly limited the development of fog last night into this morning. The patchy fog that developed over the lower Motherlode foothills and for portions of the northern Sacramento Valley diminished by mid- morning, with some mist and haze persisting into the afternoon.
Dense fog may return to some portions of the area this evening into Saturday morning, but the persistent low cloud cover will likely be a limiting factor again for fog development.
Probabilities of fog (visibilities less than a half-mile)
currently sit around 50 to 70 percent for the northern and central Sacramento Valley and the lower foothills, while the Delta, southern Sacramento Valley, northern San Joaquin have probabilities around 30 to 40 percent. Aside from periodic fog development and low clouds, cool Valley/Delta temperatures and dry weather are expected to persist through the weekend.

Next Week
Breezy north to east winds will be possible late Sunday into Monday, around 20 mph in the Valley, with the strongest wind gusts up to 35 mph expected along the Sierra. With a more persistent offshore(north-east) wind pattern setting up late weekend into next week, fog development is expected to be less relative to this past week. More normal temperatures are expected with less low cloud coverage over the Valley. Ensemble guidance then indicates some potential for an inside slider type system dropping into the Great Basin, bringing the potential for breezier north to east winds and another slight chance for mountain showers will be possible. Currently these showers look light and limited to the Sierra south of I-80.


AVIATION
MVFR conditions linger at TAF sites in BR/low stratus through the afternoon and early evening, with IFR/LIFR conditions returning in areas of FG/BR and low stratus cigs after 06z. Light and variable winds expected to persist at low elevations next 24 hours, with breezy, downsloping east winds along the Sierra after 06z.
