Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Periodically gusty winds will continue through Wednesday coincident
with unseasonably cool daytime temperatures. Warming high pressure
will gradually spread into the region during the latter half of the
week resulting in daytime temperatures returning to near normal.
With high amplitude ridging sharpening along the west coast of north
america, strong sfc pressure rises over the great basin have forced
the coldest airmass of the season to spill into SE arizona. The
magnitude and depth of the cold air have been most pronounced as
despite 500mb heights near the seasonal average, 850mb temperatures
were sampled on the 12z ktwc sounding below the lowest 5th
percentile (and very near daily records). The enhanced low level
pressure gradient and baroclinicity have supported a persistent llj
within the 925-850mb layer centered directly over the forecast area
resulting in ridge top winds gusting 40-50 mph and valley gusts near
35 mph. With only modest weakening of this gradient and maintenance
of the cold airmass through Wednesday, near persistence conditions
will exist yielding a wide range of mid 20 to lower 40 overnight
lows in the main population centers.
Through the latter half of the week, the upstream ridge amplitude
will dampen with marginally higher 576-579dm 500mb heights spreading
into SE arizona. More importantly, the loss of the more prominent e
to NE winds will allow some of the colder boundary layer to be
scoured from the region. While typically slower to occur this time
of year with reduced mixing depths, under good insolation afternoon
temperatures should rebound close to the seasonal average by the end
of the week. Given the very dry airmass and calmer winds, morning
lows may still fall cooler than average - especially for the more|
sheltered valley locations. Though notable operational and ensemble
model spread exists beyond the weekend, there are good signals
suggesting a hemispheric pattern change and better chances for
pacific storm systems moving into the SW CONUS next week.
Aviation Valid through 15 00z.
Gusty easterly winds will affect all TAF sites this afternoon in
response to a strong pressure gradient behind a backdoor front.
Winds at ktus will remain sustained at 20-25 knots with gusts of
30-35 knots, whereas sustained winds and gusts will be about 5-10
knots weaker at kols and kdug. Wind gusts should fall below 15-20
knots around 00-01z at all sites, but this will be brief at ktus
as enhanced downsloping effects will allow for gusts up to 25
knots to return after 04z and persist into tomorrow morning. Winds
will finally weaken below 10 knots at ktus late tomorrow
afternoon. Aviation discussion not updated for TAF amendments.
Periodically gusty east winds will persist on Wednesday with speeds
slightly lower than Tuesday, but still some areas in excess of 25
mph - particularly over ridge tops and foothills. While the overall
fire danger will remain low and temperatures will stay much cooler
than normal, the wind and very low rh conditions could result in
challenges with any grass brush fires during the afternoon hours.
Temperatures will moderate into the weekend with humidity levels
increasing somewhat, yet remaining quite low. The next chance of
wetting rains should not arrive in any district until at least the
middle of 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.
