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.

Quiet weather is expected across the area through next week with
near normal temperatures and dry conditions in the forecast.
Breezy conditions are likely Friday and Saturday as a low pressure
system moves into northern arizona. This system will hang around
through the weekend keeping high temperatures in the 90s. Warmer
temperatures are likely for the first part of next week with highs
just over 100 degrees.
The early afternoon water vapor imagery still shows a broad upper
level low trough circulating over the great basin. This system
will continue to lift further north away from our area through the
day. Another trough of interest that will eventually impact
the region can also be seen in satellite imagery developing off
the california coast. Meanwhile, dry southwesterly flow aloft
will allow nearly cloudless skies across arizona and southeast
california to continue. So far today, temperatures are already
pushing 90 degrees across the desert with expected highs in the
There are no significant to the intermediate forecast. Some
ridging will take hold over the area over the next few days with
h5 heights rising to 584-587 dm over south-central arizona while
staying lower further west due to the approaching trough. This
will allow temperatures across the phoenix area to climb towards
100 degrees while staying in the mid-90's for EL centro and yuma.
As that trough makes way inland Friday, strong winds will spread
across the forecast area with the strongest gusts in southeast
california. Gusts of 35-40 mph are likely, especially in the
mountain springs area of southwestern imperial county. The windy
conditions may also be capable of producing areas of blowing dust
or sand. The stronger winds will continue and become more
widespread through Saturday evening lending to elevated fire
The models are in fairly good agreement keeping the trough over
our region through the weekend. The associated height falls and
cooler air will do well to ameliorate the warmer temperatures
bringing daytime highs a few degrees below seasonal normal values.
Unfortunately, this reprieve will be short lived as ridging is
likely to reform over the southwest early next week with
temperatures again surpassing 100 degrees for the hottest areas.
South-central arizona including kphx, kiwa, and ksdl, and
southeast california southwest arizona including kipl and kblh:
no aviation concerns through Thursday afternoon under clear skies.
Outside of some periods of variable direction, trends in wind speeds
and direction will be near persistence and very typical for mid late
Aviation discussion not updated for amended tafs.
Saturday through Wednesday:
dry conditions will prevail across the region as another dry
weather system moves through. Windy conditions will begin Friday
afternoon but become more widespread by Saturday with gusts as
strong as 25-35 mph. Daytime relative humidity values will still
be low with most places in the 5-10% range. Nighttime rh
recoveries will rise into the 20-30% range. Daily high temps will
climb back into the low 100's for the hottest locations by Monday
and remaining there through at least the middle of next week.

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.
