Update Updated aviation discussion.
A warming trend will take hold this weekend and into early next
week as a ridge of high pressure develops over the southwest.
Temperatures will slowly warm to near seasonal normal values by
Sunday. Daytime temperatures will peak on Tuesday with highs
approaching 90 degrees across the lower desert.
The Friday forecast came to fruition as temperatures hit the mid
70s across the lower desert this afternoon. Temperatures will cool
tonight into the low 50s with overnight midlevel cloudiness
passing through the region.
There are no significant changes to the overall forecast with
zonal flow aloft persisting through the weekend before an
approaching pacific system allows the flow to amplify into
moderate ridging over the southwest by early next week. With the
thicker atmosphere, daytime temperatures will swell to near 90
degrees by Tuesday... Which would be the first 90 degree day of
the year for phoenix. The 30 year climatic average first 90 degree
day for phoenix is march 31st so we are nearly on target for the
season. As that afomentioned system moves across the west,
atmospheric heights will fall translating into surface
temperatures closer to seasonal normal values. Otherwise, breezy
conditions will spread across the southwest Tuesday through
Thursday with the strongest wind gusts across elevated peaks,
northern arizona and southeast california.
Quasi-zonal flow will resume in the wake of that trough by late
next week. While there is plenty of time for the atmospheric
pattern to change, the latest GEFS package suggests a second
shortwave diving into arizona very late next week, which if
nothing else, will serve well to keep temperatures at bay.

Aviation discussion not updated for amended tafs.
Monday through Friday:
there is minimal change to the intermediate forecast for next
week. The main weather concern for this period will be breezy
afternoons, especially across southeast california, western
arizona and any exposed ridge tops. The days with the strongest
afternoon breezes will be Tuesday through Thursday as a dry
frontal system pushes through the region with gusts as strong as
25 mph possible. Winds across central arizona will not be as
problematic until Wednesday afternoon. The region will undergo a
drying trend with minimum relative humidity values dropping below
15 each afternoon across the lower desert, while remaining near
20 percent in the mountainous areas. Overnight recoveries will be
in the 40-50 percent range. Otherwise, temperatures peak near 90
degrees Tuesday before a slight cooldown.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
