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.

High pressure will bring dry weather through the remainder of the
week, with temperatures peaking slightly above average on Friday.
A weak cold front will cross the region Saturday with a chance of
mountain snow showers and slightly cooler air to start next week.
* deteriorating air quality through tomorrow
* enhanced canyon winds possible Saturday night and Sunday
morning outlying washington county
exceptional drought is occurring near the four corners, with
extreme drought across weber county, uinta basin, and most areas
southeast of provo. The remainder of the state is under severe
drought, with exception of southwest utah and near the wyoming
border which is under moderate drought.
during the past 5 days, the pattern across the pacific has been
amplified but somewhat progressive. The eastern pacific ridge
briefly broke down, only to re-amplify of late.
Mdcars 400mb-200mb aircraft observations reveal a 90-135kt
cyclonic jet over the gulf of alaska becomes anticyclonic over the
eastern pacific into southwest canada.
12z kslc RAOB shows a dry and stable profile, with several
subsidence inversions below 500mb and a strong nocturnal inversion
in place. Winds were fairly uniform out of the northwest.
Precipitable water values range from 0.10"-0.20" mountains to
An expansive 1028mb surface anticyclone dominates the eastern
pacific, pacific northwest, northern rockies and the eastern
great basin. A surface trough is located from southern california
into southern arizona. This is supporting a 4mb northerly pressure
gradient across utah.
24 hour trends:
* precipitable water values are little changed
* temperatures are little changed
* rh values are 10-20% higher valleys, 15-30% lower mountains
a storm system sliding southeast into the upper plains will have
little effect on our sensible weather. With high pressure
continuing to dominate, inverted conditions will continue to
persist. Air quality is expected to continue to deteriorate
It looks like a cold front will scour out the haze Saturday, per
fv3 bufkit forecast soundings.
No changes to the forecast, other than to update the hourly t rh
curve based on the latest model data and observations.

Early this morning GOES 16 imagery shows hardly a cloud in the
sky across utah, save for a few high thin cirrus clouds passing
overhead at times. The clear conditions and light winds are making
for a another crisp morning with temperatures across the region
largely in the 20 and 30s.
This quiescent weather pattern will continue today and Friday as
a mid-level ridge axis over the great basin slowly weakens with
time. Continued airmass modification will result in high
temperatures today running a couple of degrees warmer than
yesterday and right near normal for this time of year.
Temperatures will peak on Friday, despite the mid-level ridge
being eroded by the impending wave for Saturday, as the subsidence
inversion weakens and allows for some better daytime mixing.
By Saturday, upstream amplification of the west coast ridge will
buckle the pacific jet sending a weakening shearing shortwave
southward across northeast utah southwest wyoming. The poor
dynamics and lack of moisture with this wave will result in little
sensible impact for much of the forecast area other than some
mountain snow showers for the northern wasatch and uintas, for
which some minor accumulations are possible. Cooler temperatures
will follow behind the wave passage for Sunday, however highs will
still top out just a few degrees below normal.
The amplified ridge taking shape over the great basin will
quickly break down, as forecast models have a quick moving trough
feature that will scoot through the desert southwest by Tuesday.
Models do have a tough time coming into agreement Wednesday and
beyond with another trough or slowing this trough down. Looking
farther upstream, a deepening trough dipping down from the gulf of
alaska begins to amplify the pattern in one model solution while
another begins to split the pattern flow which will result in less
precipitation chances for utah. That being said, with this
forecast package did not make many changes to the going forecast
with low confidence in any solution coming to light.
Temperatures will be on the mild side through the holiday period of
the extended forecast. The best chance for mountain snow (at this
time) looks to be a very weak chance Thursday and then better (more
agreement) chances by early Saturday. Again, this is 8-9 days out in
Light southeast surface winds currently in place are expected to
become light and variable during the 17-19z window today.
Thereafter a prevailing northwesterly surface wind will prevail
through the evening hours. AlthoughVFR conditions will be
maintained, slantwise visibility reductions are likely during low
sun angle periods.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
