109 pm pst Sun feb 17 2019
Precipitation will end from north to south across central
california late this afternoon into tonight. A cold air mass will
settle over the san joaquin valley early next week. The next
storm system should impact central california around the middle
of next week. Temperatures will remain below normal for this time
of year for at least the next several days.
An upper-level trough of low pressure will swing through central
california this evening into tonight. Precipitation will end from
north to south late this afternoon into tonight. A few hundreths
of an inch of rainfall is expected in the san joaquin valley.
There may be a couple of inches of snow in the higher elevations
of the mariposa, madera, fresno, and tulare county foothills as
well as in the southern sierra nevada. Meanwhile, farther south
in the kern county mountains, travel could be very treacherous,
with significant winter weather impacts on the grapevine and
tehachapi passes. A winter weather advisory is in effect for the
kern county mountains above 2,000 feet until 3 am pst tonight.
West to northwest winds should increase in the kern county desert
late this afternoon. Wind gusts up to 55 mph from late this
afternoon into tonight will make travel difficult, especially for
high profile vehicles. A wind advisory is in effect for the kern
county desert from 4 pm pst this afternoon until 3 am pst tonight.
The aforementioned trough of low pressure aloft will slowly
progress eastward through the desert southwest Monday through
Tuesday. Minimum temperatures in the san joaquin valley late
Monday night through early Tuesday morning in rural locations
should generally be between 28 and 32 degrees. A freeze watch is
in effect for the san joaquin valley from late Monday night until|
9 am pst Tuesday morning.
The next storm system will begin to slide southward through
western canada Tuesday night. This low pressure system will
progress to the south-southeast across the pacific northwest
Wednesday. The storm system will move southward through the golden
state Wednesday night and Thursday. Right now, it looks as if the
best chance of precipitation in the forecast area is Wednesday
night. This is another cold storm system. As a result, snow levels
could drop down to around 1,000 feet early Thursday morning before
precipitation ends. This low pressure system will move eastward
through the desert southwest late this week into the upcoming
weekend. An upper-level ridge of low pressure may be finally be
responsible for moderating temperatures late next weekend. Up
until that point, temperatures will remain below normal for this
time of year.

precipitation across the southern sierra nevada, the mariposa,
madera, fresno, and tulare county foothills through Sunday evening.

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.
