Synopsis
Low pressure and associated cold front will move
through the area this evening. Weak high pressure will return
to the area later Friday and Friday night before moving off the
coast Saturday. A warm front will stall out overhead later
Saturday through Sunday. A stronger cold front will pass through
the area Monday.

Near term until 7 am Friday morning
Cutoff low that produced the widespread showers thunderstorms
this afternoon evening now pushing eastward, and
coverage intensity of the activity will continue to decline
during the remainder of the evening. Will see westerly flow
increase behind the departing system, so some upslope rain
showers likely overnight into Friday morning. Otherwise, for the
rest of the area, drying conditions likely, with even some
breaks in the clouds developing. There may also be some patchy
fog develop in areas that can decouple. Temperatures not going
to fall much more, generally holding or falling slightly into
the 50s.

Short term 7 am Friday morning through Saturday night
Low pressure will continue to move away from the area Friday
while high pressure approaches from the west. A west to
northwest flow will usher in seasonable conditions... But it will
be breeze due to a tight gradient between the departing low and
building high. An isolated shower cannot be ruled out from
daytime heating... But much of the time will be dry.

Weak high pressure will build overhead Friday night before
moving off off the coast Saturday. A warm front will stall out
over the area later Saturday through Saturday night. Marine air
will allow for cooler conditions across northeastern portions of
the CWA while much warmer and more humid conditions are expected
across central and western areas behind the boundary. There is
still some uncertainty as to exactly where the boundary will
setup. However... With warm and humid conditions in place showers
and thunderstorms will likely develop. Sufficient shear suggests
that some storms could be severe... Mainly along and south west
of the boundary. Convection should dissipate in coverage later
Saturday night due to the loss of daytime heating.

Long term Sunday through Thursday
A warm front will settle near over our CWA Sunday
before a cold front moves across late Sunday night into Monday
morning. Showers and thunderstorms possible with periods of
heavy rain during these days. Conditions start to dry out into
Tuesday as westerly flow settles in. Another -weaker- front
approaches on Tuesday night into Wednesday, increasing pops
slightly. Several pieces of upper level energy could bring a
chance of precip to our area Wednesday into Thursday, but
looking into mostly dry conditions.

High temperatures will be in the 70s and 80s... Some 60s at
higher elevations.

Aviation 02z Friday through Tuesday
Showers and thunderstorms and their associated sub-vfr
conditions and gusty winds are weakening and decreasing in
coverage. This will lead to the return of primarilyVFR
conditions overnight. There may be some patchy fog around, but
have kept out of the tafs for now given increasing low level
wind field.

Vfr conditions are expected most of the time Friday through
Saturday night. West to northwest winds will gust around 20 to
25 knots Friday. A few showers and thunderstorms are possible
Saturday. Some storms may become strong to severe during the
afternoon and evening hours.

Sub-vfr conditions expected Sunday into Monday with
rounds of showers and thunderstorms moving through our region
with a boundaries stalled moving through. Conditions become
drierVFR Monday night into Tuesday.

Marine
Showers thunderstorms will decrease in coverage through the
evening. A small craft advisory is in effect for most of the
waters tonight as westerly flow increases behind departing
system. Gusts up to around 20 knots expected overnight.

A small craft advisory is in effect for all of the waters Friday
due to gusty west to northwest winds expected behind departing
low pressure. Winds will quickly diminish toward sunset. Weak
high pressure will build overhead Friday night before moving
offshore Saturday. A warm front will stall out near the waters
later Saturday through Saturday night. Additional showers and
thunderstorms are possible during this time... Especially
Saturday afternoon and evening.

Tides coastal flooding
Combination of high astronomical tides due to a new moon and
onshore flow will result in minor coastal flooding near times of
high tide through tonight for most areas into Friday morning.

Coastal flood headlines are in effect during this time.

Tidal anomalies should decrease rapidly later Friday due to
strengthening west to northwest flow.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
