Synopsis Lingering showers will continue over the region
through late this evening, especially over the central coast and
east bay hills with snow showers in elevations generally above
3,500 feet. Dry conditions develop on Thursday and persist into
Friday before rain returns to northern california during the
weekend and into early next week.

Discussion As of 01:39 pm pst Wednesday... Isolated showers
will continue over the central coast and out over the coastal
waters through this afternoon. Seeing some showers on radar in far
eastern napa county as well that will slide down into the east
bay and then forecast to push into santa clara, monterey and san
benito counties through early this evening. Overall, rainfall
amounts are generally a few hundredths to one- tenth of an inch
with each passing showers. Given the cold air mass aloft, small
hail will also be possible within the heavier showers and snow is
likely occuring in elevations at or above 3,500 feet. Lingering
showers look to potentially continue over the mountains above the
big sur coast into Thursday morning. Otherwise, showers will
tapper off late this evening and tonight across much of the region
as the short-wave disturbance exits.

Sky conditions will clear late tonight into Thursday with
temperatures again turning colder. Look for more widespread 30s for
inland areas and lower 40s near the coast on Thursday morning.

Daytime temperatures will warm into the 50s for most urban locations
while areas in the hills higher elevations will be slightly cooler.

This trend will continue into Friday with ongoing dry conditions as
a weak short-wave ridge develops.

The forecast models are converging in their solutions heading into
the weekend with increasing chances of precipitation over northern
california. At this time, the best chance for rainfall will be over
far northern sonoma and napa counties Saturday morning and then
southward to around the golden gate by the afternoon evening. Most
areas south of san francisco look to remain dry through this period.

Rain chances potentially shift southward on Sunday and linger across
the region during the first part of next week. However, the best
chances for widespread rainfall look to stay over the northern
portion of the region. If even a weak atmospheric river takes aim at
the north bay late in the forecast period, the potential for
flooding concerns would greatly increase. Folks are urged to monitor
the forecast in the coming days.

Looking out a bit further, longer range guidance suggest an
unsettled pattern with potential for widespread rainfall over the
region heading into the beginning of march. The CPC has our entire
region depicted in a 50% probability of above normal precipitation
from february 28th - march 6th. Stay tuned... The winter season
continues.

Aviation As of 09:30 am pst Wednesday... For 18z tafs. Still
expecting CIGS to lower this morning, but generally remain above
4,000 ft. BorderlineVFR MVFR CIGS through the early afternoon
before CIGS begin to rise. Showers to remain in the vicinity

gusts 20 to 30 kt with the windiest conditions still forecast for
the bay area TAF sites. Winds should taper off tonight.

4,000 ft into the afternoon before CIGS are expected to lift.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
