national weather service san joaquin valley - hanford ca
422 am pdt Tue oct 17 2017

Synopsis
There is a slight chance of a few showers and thunderstorms this
afternoon and evening. Little if any rainfall is expected with the
main threat being dry lightning along with gusty and erratic winds.

Otherwise, temperatures will remain above normal through Wednesday
then trend much cooler through Friday. There is a chance of light
rain Thursday night and Friday along with increasing winds. Dry
conditions return this weekend with temperatures trending warmer.

Discussion
Goes-16 IR satellite imagery is showing a large area of convection
centered about 300 miles southwest of point conception this morning.

This wave of sub-tropical moisture is moving towards the northeast
and will shift inland over the central coast later this afternoon
and tonight. Most of the model solutions indicate little activity
as it does so. But the hrrr shows an area convection crossing into
the san joaquin valley from fresno county to kern county late this
afternoon and evening and have added slight chance pops for this.

Convection would be elevated with moisture generally above 10,000
feet. So unless a strong thunderstorm were to develop, mainly just
sprinkles or brief light rain is expected. Any thunderstorm would
bring the potential for dry lightning as well as gusty and erratic
downdraft winds. A slight chance of showers and thunderstorms will
remain across the high sierra on Wednesday afternoon.

Broad high pressure remains over the southwest with a mild air mass
in place. Temperatures are forecast to be around 4-8 degrees above
normal today and Wednesday. A sharp cooldown will occur by the end
of the week as a trough drops down from the gulf of alaska. High
temperatures by Friday are expected to be around 10 degrees below
normal with some upper 60s in the san joaquin valley.

While some precipitation is still expected, the models have trended
drier the last couple of days. Some light rain is possible around
merced county to yosemite np by Thursday evening. Chances spread
southward through Friday and a few showers could make it all the
way down to kern county. But rainfall amounts should generally be
less than a tenth of an inch throughout the district. The trough
axis quickly shifts east Friday night, ending any rain chances.

The surface flow will begin to transition to onshore today with
some moderately gusty conditions through passes by this evening.

Winds will increase Thursday into Friday with the arrival of the
trough. Gusts may approach advisory levels by Friday, especially
through and below the kern county mountain passes.

There is good model agreement with strong high pressure building
in from the pacific over the weekend and into next week. So the
cooler weather will be short-lived with highs bouncing back to
near normal by Sunday then well above normal early next week.

Aviation
Areas of MVFR visibilities due to smoke can be expected in the san
joaquin valley, southern sierra foothills and higher elevations of
the southern sierra nevada for at least the next 24 hours, withVFR
conditions prevailing elsewhere across the central california
interior. Isolated thunderstorms possible in the san joaquin valley,
foothills, sierra nevada, and kern county mountains from 20z
Tuesday through 06z Wednesday.

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.
