Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis High pressure aloft will build over the region
Thursday into Friday. The next pacific storm system will move into
utah and southwest wyoming on Saturday, continuing to impact the
area through Tuesday.
Short term (through 12z Saturday) The low pressure system that
had been over the forecast area is currently centered over north
central wyoming. Lingering shortwave energy on the back side of
the system is providing the instability for popcorn convection,
greatest in coverage over northern utah. These storms will tend to
weaken due to the loss of daytime heating and the storm system
continuing to pull northward.
Behind the exiting storm system, high pressure aloft will move
into the region for tomorrow into Friday, resulting in a drying
and warming trend. Cannot rule out a few showers over the higher
terrain, but overall the drier and more stable airmass will tend
to suppress convection. Utah and southwest wyoming will see
noticeably warmer temperatures tomorrow with maxes running in
excess of 10f above seasonal normals, with the mild temperatures
continuing into Friday.
Long term (after 12z Saturday) The unsettled, cut-off low pattern
continues with the next trough digging south through the great basin
as we head into the weekend. While this system appears to be lacking
in moisture (as of now, fairly weak), with precipitable water values
less than half an inch, the diffluent flow aloft and strong
(relatively) jet dynamics should be enough instability to generate
afternoon showers and (isolated) thunderstorms. Global models are in
rather good agreement through most of the extended period, for
better or worse.
Prior to this system swinging through, temperatures will be running
warm. This system draws in some cooler air aloft, and with increased
cloud cover, day time highs early into next week will be a bit
cooler than days before, however still remaining near seasonal
Winds on Saturday look to be the strongest of the period, as the|
storm creates a tight gradient pushing through the desert southwest.
As the low slowly weakens and opens up by early next week, heights
will build (although, for a short period of time) under weak
ridging. For the extended period kept the going forecast while
adjusting the pops on Saturday and Sunday to better reflect the
coverage of showers.
Aviation There is a 30 percent chance of showers thunderstorms
impacting the slc terminal between 21z and 03z, with erratic winds
as the most likely impact. Otherwise, light northerly winds will
likely prevail, before switching to the southeast around 01-03z.
Fire weather The storm system that has been impacting the
district is heading northward out of the area today and will fully
exit tonight. Behind it, high pressure aloft will build in for
Thursday into Friday, resulting in drier, warmer, and more stable
conditions. Winds will pick up Friday ahead of the next system,
resulting in breezy conditions for some locations, particularly
over southern and western utah. The airmass will be dry enough by
then for there to be isolated severe fire weather conditions but
fuels are not yet critically dry. The pacific storm system will
move into the district Saturday, slowly moving across through
Tuesday. This will result in noticeably cooler temperatures, and a
return of showers and thunderstorms, especially over northern

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.
