Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis Increasing temperatures through the remainder of the
week with an extended period of record or near record high
temperatures expected Wednesday through Sunday. Early next week a
low pressure system will push across the pacific northwest leading
locally breezy conditions and cooling temperatures. &&
Discussion Through Monday.
Warming trend already underway as a strong ridge of high pressure
builds over the southwest and remains in place for the coming days.
500mb heights of 588dm+ are already progged to be overhead by this
evening, with heights rising further Wednesday to 590+. That is much
more comparable to mid-summer heights than late fall. Despite the
abnormally strong ridge, the low Sun angle and lack of surface winds
will greatly limit the heating potential of this powerful ridge, but
we are nonetheless expecting record temperatures over the next few
days. Along with this ridge will come pesky inversions, especially
in the mornings, which will result in hazy smoggy skies for the urban
areas that will linger much of the week.
Currently anticipating tomorrow being the warmest day of the next
several as the ridge axis amplifies roughly along the colorado river
and abundant sunshine aids in warming. Without surface winds
promoting mixing, I somewhat question the ability for las vegas to
reach 80 degree temperature territory as 80f temperatures this late
in the year can be counted on just a few fingers. However, given the
strength of the ridge and consistency of MOS guidance, it's hard to
argue with it. Outside of vegas, should see temperatures in the mid
80s down the colorado river, and near 90 in the lower reaches of
Increased clouds move in Thursday which should reduce afternoon
temperatures a tad, though widespread record temperatures are still
anticipated. Our region will remain under the influence of broad
ridging through Saturday, with near record temperatures persisting.
Only glimmer of hope for a change in the weather comes late this
weekend as a trough moves across the great basin, dragging a cold
front and some sierra precipitation southward. Confidence is low on
the details at this point, so just added slight chances of precip to
the sierra Sunday-Monday and cooling temperatures.
Climate Temperatures during the latter half of this week will
jump to record territory. Below is a table of some of the threatened
high temperature records.

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.
