Synopsis
A fast moving and potentially windy storm system drops into the
great basin on Thursday and Thursday night. A best, spotty
showers will also be observed during storm passage. High pressure
will return for more springlike conditions for the weekend.

Discussion
Upper level ridge over the west coast today provided for sunny
conditions and warm temperatures. While snow cover continues to
keep some of the higher elevations of the sierra nevada on the
cool side, valley temperatures were able to reach into the lower
70s. Furthermore, winds continue to remain light across the region
ahead of another storm currently pushing through the pacific
northwest. Current timing has this next storm moving closer to the
district late overnight into early Thursday morning.

Change will usher into the district late overnight as short range
meso-scale models prog a return to unsettled conditions on
Thursday. Precipitation is expected, mainly over the mountains
north of kern county, and across the northern portions of the san
joaquin valley on Thursday. In addition, the best chances of
precipitation will exist over the higher terrain, with minimal
accumulation expected. The big concern with this next storm system
is in the field of wind. A strong temperature gradient from north
to south along with a plus 130 knot jet MAX over central
california on Thursday will support strong surface winds during
the day. A wind advisory is currently in effect as winds are
expected to gusts in the excess of 50 mph across the kern county
mountains and deserts.

The next storm will begin to exit the region on Friday as it
pushing into the four corners area. While lingering cyclonic flow
will keep the district unsettled, the potential for precipitation
will diminish on Friday. Ridging will not exist over the region
until Saturday as a weak short-wave ridge crosses the region. The
transitory ridge will allow another trof to enter the region
early next week. While more uncertainty exist with the second
storm system, clouds and winds could reach the central california
interior on around Monday. Higher confidence level exist with the
timing of this storm then with the amplitude. Because of the
higher confidence in timing, will expect another ridge pattern
over the region toward the middle of next week.

Aviation
Vfr conditions are expected across the central ca interior for
the next 12 hours. Possible mountain MVFR and local ifr conditions
may be observed after 12z Thursday, north of kern county. Strong
winds may develop after 18z Thursday, especially over the kern
county mountains and deserts.

Air quality issues
None.

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.
