Marine Weather and Tides
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.

Anticipate little change in temperatures Friday as high pressure
remains situated across northern mexico. Temperatures increase
over the weekend. Storm chances return to the higher terrain as
well. Temperatures start to decline on Monday but still
excessively hot in some areas. Modest additional cooling is
anticipated Tuesday and Wednesday.
Mid-afternoon temperatures are running several degrees lower than
those observed 24 hours ago. This is due in large part to the
increase in low-level moisture. Surface dewpoints are running 5 to
as much as 20 degrees (across SE ca) above what they were this
time yesterday. Moisture however remains too low to generate cape
and initiate convection across the lower deserts.
Isolated shower and thunderstorm activity has mainly been
confined to the mogollon rim this afternoon. Westerly flow around
the anticyclone to the south will continue to steer storms away
from the lower deserts and pops are near 0 percent for tonight.
Otherwise, temperatures overnight will be cooler than those the
past few nights but still above normal.
Friday through Sunday...
the high will sag southward on Friday and dew points will decline
as well. Anticipate little change in temperatures. Over the
weekend, ridging consolidates over the west and the high
strengthens. Accordingly, temperatures increase at least a few
degrees. Expecting to stay below records but we may be only a few
degrees below the peak values we saw on Tuesday. A complicating
factor will be the return of deeper moisture into arizona as a
backdoor front pushes against the southern continental divide.
However, models are not indicating a major influx that would lead
to widespread storms. Rather, it would be more like what we've
seen the past couple days with high-based storms over the favored
higher terrain areas of arizona sending outflow pretty far afield
to the lower elevations. Unfavorable steering flow will also tend
to prevent storms from getting to the central arizona deserts
(including metro phoenix). Anticipate Sunday afternoon evening
being more active than Saturday.
Monday through Wednesday...
a combination of higher dew points and debris clouds will nudge
temperatures down a bit on Monday. However, a number of locations
will still reach high to very high heat risk levels. Thus,
extended the excessive heat warning to Monday for portions of our
forecast area including metro phoenix. A trough passing to the
north will weaken the ridge leading to a modest cooling trend
Tuesday and Wednesday. Anticipate a decrease in storm activity
over arizona but not altogether since there will still be some
lingering moisture over the southeast third of the state.
South-central arizona including kphx, kiwa, and ksdl:|
west winds occasionally gusting to around 20 kts will continue
through late afternoon, subsiding after sunset. The switch to
easterly winds will occur later than normal, around 10z at kphx.
Temperatures will be slightly cooler than previous days, and
should remain critical thresholds. Intermittent high clouds will
continue through tomorrow afternoon.
Southeast california southwest arizona including kipl and kblh:
no aviation impacts through Friday morning as skies remain mostly
clear. Winds will favor a southerly direction, especially during the
afternoon and early evening hours. Some afternoon breeziness is
likely at kblh with gusts near 20 kts.
Aviation discussion not updated for amended tafs.
Sunday through Thursday:
high pressure will generally remain positioned over the southwest
through late next week, maintaining above normal temperatures. A
modest increase in moisture will occur next week, but still should
see minimum rh values in the 10-20% range each afternoon. Isolated
thunderstorms are possible each afternoon across the higher
terrain of south-central arizona, including southern gila county,
but rainfall amounts will be light. Lightning ignitions remain a
concern given the dry sub-cloud layers, along with gusty outflow
winds. For now, it appears any significant moisture intrusion will
hold off until after the period, maintaining dry fuel conditions

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.
