AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
330 PM PST Mon Nov 24 2014

.Synopsis...
High pressure will bring dry and increasingly mild weather
through Thanksgiving. Rain is expected to return to the region by
Friday and continue into early next week. Accumulating mountain
snow is likely to cause travel difficulties for the holiday
weekend.

&&

.Discussion...
High pressure ridging over the area has brought mostly sunny skies
and warmer temperatures. Temperatures are as much as 10 degrees
warmer (in Redding). Patchy fog and mist is expected to develop
in the Valley again early Tuesday, especially in the northern San
Joaquin Valley and southern Sacramento Valley.

Dry weather with more sun and and even milder temperatures
expected through Wednesday, with no travel concerns except for
occasional morning fog. Thanksgiving will be dry and pleasant,
with just some increasing cloud cover through the day possible. EK


.Extended Discussion (Friday through Monday)

Medium-range models continue to be in good agreement, swinging the
first in a series of cold fronts through Northern California on
Friday into Friday night. Unsettled weather will likely continue
through next weekend with strong jet dynamics and good diffluent
flow aloft. The strongest precipitation is likely to be toward the
end of the event -either Sunday or Monday- as the cold upper low
approaches the region. The trend for the last several runs of both
the GFS and ECMWF has been to both deepen and moisten this system.
With this in mind, it would not be surprising to see the models
prog this system to slow down a bit further. The primary impacts
anticipated will be to Thanksgiving holiday travel and the
potential for fallen leaves to cause clogged drains and localized
flooding.

.Aviation...

VFR conditions for today into early tonight as high pressure
remains in control. Northerly winds will generally be light under
7-8 kts. Valley fog expected again late tonight into Tues morning
with MVFR and possibly IFR/LIFR visbys under clear skies and light
flow.
