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 A low pressure system over central california will
move east into the great basin Saturday. This low pressure will
generate widespread precipitation and cooler temperatures across
mainly northern and central utah through the holiday weekend.
High pressure is expected to return for the middle of next week.
Short term (through 06z Tuesday) The upper low over central
california this evening will work slowly east into the western
great basin Saturday morning. From there this low will expand
across the rest of the basin and then stall over the area for
the balance of the holiday weekend.
Through Saturday morning dry and breezy conditions will continue
with temps remaining above late may norms ahead of the advancing
upper low. Terrain-based convection should begin to show up during
the afternoon, though with little moisture to advect north into
utah this convection will likely produce more clouds than precip.
Convective precip will likely expand quickly late Saturday
evening across southwest through northern utah. Increasing
synoptic-scale lift along with increasing moisture and significant
mid-level cooling will create a more favorable environment for
convection Saturday night. Precip will become widespread and more
stratiform as the upper low stalls over utah Sunday Monday.
Embedded convection will remain a possibility, with Sunday the
mostly likely time for this to occur. The heaviest precip should
remain along the northern and eastern flanks of the upper low,
with lesser areal coverage of convection across southern eastern
utah through the holiday weekend.
Precip will begin to wind down and turn more convection again late
Monday afternoon evening as the center of the low lifts north
toward the northern rockies. Precip for the most part should end
by late in the evening as high pressure aloft to the west advances
across the great basin.
Previous long term (after 06z Tuesday) The closed low from the
memorial day holiday will continue to fill and weaken as it pulls|
northeast of our area late Monday into Tuesday. A few lingering
showers are possible (especially if the closed low slows down),
but otherwise clearing skies and a warming trend can be expected
by later Tuesday as a ridge builds in over the great basin.
The weather pattern over the western us begins a notable transition
towards the middle of next week. The general theme over the last few
weeks has been a parade of closed lows meandering into the great
basin. In contrast, global models are showing a consolidated
longwave trough developing along the west coast by the middle of
next week. In advance of that trough, models indicate strengthening
southwest flow over our area, bringing warmer temperatures and
breezy conditions for the Wednesday Thursday timeframe. Afternoon
showers thunderstorms can't be ruled out under this pattern,
mainly over the higher terrain of utah with a slight chance for
northern utah and southwest wyoming valleys. Forecast confidence
then drops off quickly with the evolution of the aforementioned
trough. Models struggle with the trough as it moves inland; the
ecmwf pushes a weakening trough axis through the great basin
Thursday into Friday with a chance of precipitation and cooling
trend for us, while the GFS and canadian push a deeper trough
inland about two days later. In either case, the general theme is
cooler and perhaps wetter towards the end of next week.
Aviation Vfr conditions under clear skies will continue at the
slc terminal through Saturday morning. Southeast winds will develop
at the terminal between 05z and 06z, then turn to the south early
Saturday. Winds will become gusty out of the south by late

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.
