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.

The unsettled weather pattern with a trough over the western
united states will continue through Friday. There will be a
hiatus Saturday into Sunday with a weak ridge moving in between
systems but another trough returns early next week.
Short term (through 00z Sunday Easterly flow from southwest
wyoming has spread into the cache valley and portions of the
northern wasatch this afternoon. With the surface gradient
becoming more favorable and the mid level easterly winds at 700 mb
increasing to 35-40 kts the pattern will result in gusty
downslope canyon winds along the northern wasatch front and the
cache valley tonight into Thursday morning. Consequently the wind
advisory remains in effect with potential wind gusts over 50 mph.
Due to drier air being imported from the east the threat of
showers across northern utah, specifically the wasatch front from
slc northward will diminish early this evening. Farther south, the
latest trough developing over california will begin to influence
the weather over southwest and south central utah this evening
with an increase of showers and thunderstorms as a lobe of
vorticity advection swings northward.
A couple of 700mb circulations are expected to spin up overnight
with one near saint george and another near dugway by 12z
Thursday. These circulations will increase the shower activity
during the morning time frame. As the northern circulation becomes
dominant by afternoon the showers will decrease over southwest
utah but become more numerous over central and northern utah as
the instability due to the cold air aloft increases. In the path
of the main circulation and to the east another 0.20 to 0.50 of
an inch of rain is expected in the valleys with 0.25 to 0.75 in
the mountains through Thursday. Several more inches of snow above
7500-8000 ft can be expected as well.
The mid level circulation lifts northeast away from utah and sw
wyoming Thursday night into Friday. However, an elongated 500mb
trough remains in place from southeast idaho into southern
california through Friday which will keep a chance of showers
across central and northern utah, with likely showers to continue
in the northern and central mountains.
This trough fades away while a new one forms over california by
Saturday. This will result in a temporary break in the widespread
showers, although due to the incumbent moist air mass showers will
remain possible, especially over the northern mountains.
Temperatures will remain below normal through this period,
although temperatures could come within 5 degrees of normal by
Saturday which may feel like its above normal compared to recent
Long term (after 00z Sunday) The upper low drifting slowly south
through the pacific northwest will settle into central southern|
california and western great basin Sunday Sunday night. This
general location of this upper low is similar to recent storms,
and will likely result in another round of widespread precip early
in the week.
A warm and mostly dry southerly flow ahead of the main low should
make Sunday the warmest of the days in the long term forecast
period. Good diurnal heating working with limited moisture should
spawn mostly terrain-based convective cloud cover with some shower
and thunderstorm activity during the late afternoon.
The best chance at organized precip will likely hold off until the
first vorticity lobe rotates out ahead of the main low into
southwest utah late Sunday afternoon or evening. Widespread
convective precip will expand across the entire forecast area in
response to the approach of the upper low into southern western utah
by early Monday. This precip will turn more stratiform late Monday
through early Tuesday as the low moves east across the state. Near
700mb temps will be sufficiently cold to drive the snow level of
accumulating snow down to between 7000'-8000' during this timeframe.
The trailing cool and moist cyclonic north-northwest will maintain
precip Tuesday through early Tuesday evening. Snow levels will begin
to slowly climb as precip intensities decrease and temps aloft begin
to warm. Continued warming and gradual drying should limit any
precip to mostly terrain-tied showers for Wednesday.
Aviation Light rain over near the slc terminal expected through
the afternoon. Ceilings in precip will range between 2500-3500 feet,
otherwise ceilings at or above 6000 ft agl are expected through the
After 00z, winds will become the primary issue at the terminal.
Downslope winds are expected across the wasatch front, creating
northerly surface winds at the terminal as the winds flow south from
farmington. There is a 30% chance of the winds becoming southeast
as an eddy develops around the mountain or if the salt lake
county downslope winds are stronger than forecast. Also impacting
the terminal will be moderate to severe turbulence in the lowest
10 kft agl due to the downslope winds.

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.
