Synopsis A gradual warming trend is forecast through midweek
with very warm to hot temperatures expected across the interior.

Meanwhile, onshore flow and marine air will hold temperatures down
near the coast. Inland areas are expected to cool slightly during
the second half of the week.

Discussion As of 8:50 pm pdt Sunday... Low clouds this evening
are much less extensive compared to last evening, even through
synoptic pattern and marine layer depth have changed very little.

One possible explanation is that gravity waves propagating away
from widespread thunderstorms over the sierra may have produced
enough turbulent mixing to temporarily disrupt the marine layer.

In any case, expect low clouds to gradually become more widespread
overnight.

A strong upper ridge continues to dominate the southwestern u.S.

And currently extends from texas west to california. The ridge is
currently centered over new mexico, but is forecast to slowly
retrograde and be centered over southern california by midweek.

This will result in a gradual warming trend through the first
half of the work week, but primarily across inland areas. The
marine layer will likely compress slightly from its current depth
of 1500 feet, but onshore flow is forecast to persist and thus
coastal temperatures will remain mild. The warmest days for inland
areas this week are expected to be Tuesday and Wednesday. On
those days, highs will mostly be in the 90s across inland portions
of the sf bay area, with a few of the hottest spots reaching
triple digits. Farther to the south, across interior monterey
county and san benito county, widespread highs of 100 to 108 are
projected for Tuesday and Wednesday. In addition, areas in the
hills above 1000 feet will remain warm at night with overnight
lows forecast in the 70s. The combination of hot temperatures
during the day and warmth in the overnight hours will raise heat
risks into the high category across much of san benito county and
interior monterey county on both Tuesday and Wednesday. Thus, a
heat advisory is in effect for these areas from noon Tuesday until
9 pm Wednesday. One other isolated area that may also see high
heat risk in the Tue Wed time frame is the eastern portion of napa
county around lake berryessa.

The upper ridge is forecast to gradually weaken during the second
half of the week which will result in a modest cooling trend from
Thursday through Saturday. However, longer range models maintain
an upper ridge across the southwestern u.S. Through at least the
middle of next week and the latest 8-14 day outlook from the
climate prediction center indicates above normal temperatures
across all areas west of the rockies.

Aviation As of 10:30 pm pdt Sunday... Moisture in the mid
levels has weakened and disrupted the marine inversion and may be
causing less stratus this evening. Models forecast drier air aloft
during the night and the stratus is expected to return to the sfo
and mry bay area later tonight. Marine layer currently around
1500 feet is expected to compress a bit as upper level high moves
over the state. Typical onshore flow so typical burnoff time of
the stratus of around 17z.

Vicinity of ksfo... Ifr CIGS after 11z clearing after 17z.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals... Stratus over southern mry bay cleared
before sundown and is presently confined near wvi. Still expecting
cigs to come in after 08z clearing after 17z.

Marine As of 10:24 pm pdt Sunday... Generally light
northwesterly winds will continue across the coastal waters
through Tuesday except for locally stronger winds near coastal
jets. A mixed northwest swell and long-period south swell will
continue through midweek.

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.
