.SYNOPSIS...A weak trough extending N from the remnants of
Tropical Storm Mario will push N into the southern waters tonight
through Thu, then dissipate Thu night. Meanwhile, a high pressure
ridge over the northern waters will shift SW of the area tonight
as a cold front moves S into the area. The front will dissipate
over the central waters Wed night. Behind the front, a coastal
trough will develop Wed night and persist through Thu night,
while strong high pressure well W of the area builds slightly E.
A weak area of low pressure will develop along the coastal trough
on Fri near Point Arena, then drift SW into the central waters
Fri night and Sat. The coastal trough will reform late Sat night,
as ridging becomes established over the northern waters, then
persist through Sun night. A cold front will move S into the
northern waters Sun before quickly dissipating. The USCG
transmitter at Point Reyes California is experiencing technical
difficulties. Technicians are aware of the problem. We apologize
for any inconvenience.
