Synopsis Temperatures will rise back to above normal levels
this weekend as high pressure strengthens over the region. Dry
conditions will prevail this weekend except for the possibility
of an isolated thunderstorms over the southern sierra nevada
Sunday. A moist southerly flow will bring a chances of
thunderstorms to the mountains and kern deserts on Monday and
Discussion Large upper ridge over the south central CONUS is
progged to retrograde westward this weekend which will bring a
warming trend to our area as heights and thicknesses rise after
two days of near seasonable daytime temperatures. A weak
disturbance pushing inland just to the north of our area
overnight brought some mid high clouds to the northern most
portions of our cwfa overnight. Otherwise clear skies prevailed
although smoke from the detwiler fire persists over the southern
sierra foothills as well as portions of the higher southern sierra
Meanwhile, WV imagery indicating another shortwave near 36n 134w
which is progged to reach the norcal coast on Sunday then remain
quasi-stationary on Monday and Tuesday as the retrograding ridge
halts it's eastward progression. Interaction between this system
and the ridge to our east will result in increasing southerly
flow which will allow for increasing mid upper level tropical
moisture to stream into socal Sunday through Tuesday providing
for a slight chance of afternoon evening thunderstorms near the|
southern sierra crest on Sunday and increasing chances of diurnal
convection on Monday and Tuesday over the mountains and kern
The medium range models remain in good agreement with an upper
trough pushing into the pac NW on Wednesday which will turn the
upper flow westerly resulting in any tropical moisture over
central ca to be pushed east of the area resulting in a drying
trend and only minimal chances of mountain convection. The ridge
is progged to strengthen again over ca later next week.
Temperatures will lower to near normal by the middle of next week
as the ridge temporarily weakens then rebound to above normal
levels by the end of next week. Some uncertainty exists if any
mid upper level tropical moisture will return to our area late
next week. For now will opt to keep the forecast dry until there
is better models consensus on increasing moisture late next week.

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.
