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 Dry conditions continue this week. A warming trend will
result in the hottest temperatures of the year so far occuring
Friday. Temperatures will moderate slightly over the weekend.
Discussion Sunny skies will prevail across the area today with
near normal high temperatures expected. Current temperatures in the
upper 70s lower 80s in the valley locations across southern arizona
will top out in the upper 90s to lower 100's during the mid to late
afternoon hours. Dewpoint temperatures in the 30's to lower 40's
this morning will mix out as the day progresses. Overall, forecast
package in good shape and on track. No updates this morning. For
more information on the latter periods of the forecast, please refer
to the prev discussion section below.
Aviation Valid through 21 12z.
Clear with light diurnally driven winds thru fcst pd. Aviation
discussion not updated for TAF amendments.
Fire weather Dry conditions persist through the forecast period,
although surface moisture does increase temporarily over the
weekend. Temperatures continue to warm each day, peaking near 110
degrees across the lower deserts on Friday. Daily wind patterns
remain diurnally driven and generally 15 mph or less, although some
late afternoon breeziness is forecast Friday through Sunday with
speeds up to 20 mph possible.
Prev discussion A clear sky prevailed across southern arizona this
morning under high pressure aloft. Last evenings upper air plots
placed the upper high center just off SRN ca NRN baja coast. This
upper high will expand across the desert southwest as the high
center moves across southern arizona. This will result in warmer
daytime temperatures for the remainder of the work week, peaking on
Friday, where the hottest temperatures of this year are possible.
Still some uncertainty on how hot it will get on Friday where we
currently have a excessive heat watch out for the lower elevations
of pinal, pima and graham counties. At this time will hold off on
upgrading the watch to warning.
The upper high is suppressed south over the weekend as weather
systems pass by well to our north. This will allow for moderating
temperatures this weekend, closer to normal values. Once the system
moves into the central plains early next week, the upper high will
re-establishes itself over the desert southwest. This will bring
back hotter daytime temperatures.
No rain in sight over the next 7 days and likely thru the end of the
On an astronomical note, the summer solstice is tomorrow at 3:07 am.

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.
