Synopsis Showers will come to an end this evening. Gusty
southerly winds and wet weather will return to the area late
Sunday into Monday morning. Wet weather will continue
intermittently through much of next week. A few thunderstorms
will also be possible on Monday.

Discussion Shortwave trough is currently traversing the area
which has led to numerous showers across the interior. As the sun
sets and instability wanes, most of these showers will come to an
end leading to a clearing evening as weak ridging builds in.

Clearing skies will allow for radiational cooling this evening
across the interior and interior mendocino county may see some
patchy frost develop tonight. The one question regarding frost
formation would be how much low level moisture remains present as
this may prevent temperatures from dropping as low as expected.

Sunday will also be a pleasant day however upper level cloudiness
will be on the increase ahead of the next low pressure system. As
the low approaches the coast, southerly winds will be on the
increase Sunday night and will peak Monday morning. As the low
and cold front move across the region Monday moderate rain will
come to an end but a more unstable airmass will move in. Steeper
lapse rates and increasing MUCAPE will lead to more showers and a
marginal thunderstorm risk mainly across the northern half of the
area Monday afternoon.

A broad upper level trough will remain across the northeastern
pacific ocean for most of the week with disturbances rotating
around it. This will lead to several rounds of precipitation
throughout next week. Early indications are that the pattern may
become more progressive late next week which may bring an end to
this wet period. Wci

Aviation MostlyVFR to MVFR conditions are expected at all
terminals through the TAF period, though showers will linger across
the interior through this evening. Mainly light winds are forecast
across the area through tonight, with scattered cloud cover
anticipated through this evening. Skies should be mostly clear by
tonight, but some low clouds and valley fog will be possible.

Marine Generally light westerly winds will become southerly late
tonight and increase Sunday afternoon as the next system approaches.

Winds will be around 20 to 25 knots across most of the waters by
late Sunday evening. Winds will decrease overnight on Monday and
increase again Tuesday afternoon. Seas will remain elevated through
tonight, before briefly coming down Sunday morning. The increasing
southerlies will result in the development of short-period wind
waves through Monday. Combined seas will be around 12 to 13 feet
from Sunday evening through early Monday morning across the outer
waters and around CAPE mendocino. Seas will begin to come down
Monday afternoon, eventually dropping below 10 feet across all zones
on Tuesday. Additionally, another westerly swell will move through
the waters later on Monday and into Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
