Synopsis
Temperatures around average thru mid-week, then warming above

thunderstorms possible over the mountains thru Wednesday.

Discussion
Some mid and high clouds possible today across interior norcal in
the deformation area to the north of the upper low off the central
california coast, and some smoke haze could linger due to numerous
wildfires still burning across oregon and NW california. However,
overall conditions should be pretty good for eclipse viewing this
morning.

Upper low lingers off the central california coast through mid-
week. This will continue a chance of afternoon and evening
thunderstorms over mainly the mountains through Wednesday.

Thunderstorms may be more extensive on Tuesday as a wave lifts up
from the southeast, and a fire weather watch has been posted
across the far northern portion of the forecast area due to the
potential for abundant lightning.

Moisture and instability forecast to be scoured eastward by
Thursday as a trough in the northern stream moves through the
pacnw. Temperatures expected to be below average early this week
then warm back to above average after mid-week.

.Extended discussion (Friday through Monday)

upper level high pressure positioned over the west will keep clear

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.
