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 and clear conditions will continue this week. A
warming trend will result in the hottest temperatures of the year so
far occuring on Friday. Temperatures will then moderate over the
weekend and into next week. Some moisture will move into the area
over the weekend for increasing clouds and possibly a build-up or
two southeast of tucson.
Discussion Clear skies across southeast arizona this evening with
very dry conditions as the 00z ktwc soudning depicts pwat values of
0.40 inches with surface dewpoints in the teens and 20's. Latest wv
satellite imagery shows the subtropical high centered just to our
west. The subtropical high will remain nearly overhead into Friday
as daytime temperatures continue to warm across the area with Friday
looking to be the hottest day before modest cooling this weekend.
Current forecast in good shape this evening, no updates. See
previous discussion for additional information.
Aviation Valid through 22 06z.
Clear skies with light diurnally driven winds and the occasional
afternoon gust. 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 around 105-
110 degrees across the lower deserts on Friday. Daily wind patterns
remain diurnally driven and generally 15 mph or less, although some
afternoon breeziness is forecast Friday through Sunday with speeds
up to 20 mph possible. The strongest winds should occur Saturday,
particularly across areas northeast to east of tucson.
Prev discussion Clear skies will continue across southeast
arizona into Friday as high pressure aloft shifts into region from
the west. This ridge of high pressure will be nearly overhead
Thursday into early Friday, resulting in warmer daytime
temperatures, with readings peaking Friday when the hottest|
temperatures of this year are possible. An excessive heat watch
continues in effect for Friday for the lower elevations of pinal,
pima and graham counties. Still uncertain if temperatures will be
quite as hot as initially thought on Friday as the latest guidance
numbers continue to trend a little lower in most places (except the
gila river valley at safford). These lower guidance values are in
response to a trough which will move across the great basin on
Friday and begin to suppresses heights and thicknesses values.
By late Friday into early Saturday, the center of the upper high
shifts westward into the eastern pacific ocean west of the baja
peninsula. The ridge of high pressure will then move north into
california on Sunday and near las vegas by Tuesday. This will result
in moderating daytime temperatures, as readings lower from near
normal on Saturday, to a couple of degrees below normal Sunday and
Monday. Wind speeds will increase into the breezy category on
Saturday and Sunday, mainly across eastern areas (and especially in
the upper gila river valley near safford).
As the upper high retreats westward late Saturday and Sunday it will
allow a little moisture to seep northward along the international
border from nogales to the new mexico state line. We will likely see
a CU field set up over portions of our eastern counties and even the
possibility of a build-up or two. However, precipitation is not
likely as very warm mid-level temperatures remain a prohibiting
factor for convection.
The models then diverge considerably mid late next week as the gfs
shifts the upper ridge to our east, while the ECMWF digs an upper
low southward along the california coast. Confidence remains low
during this time frame.

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.
