Update Updated aviation discussion

Synopsis
Building high pressure this weekend will result in a significant
warming trend with high temperatures reaching into the middle 90s
by Monday. The very warm and dry conditions will last through the
coming week with highs nearing 100 degrees over the warmest
desert locations.

Discussion
Temperatures will continue to warm up over the next few days with
heights aloft rising slightly into the middle part of the week.

Current satellite imagery shows a weak cyclonic circulation over
the northern baja with modest upper level moisture now over much
of the desert southwest. As this weak circulation passes by mostly
to the south of arizona today, periods of mid and high clouds
will affect the region. Skies today will for the most part be
mostly sunny with temperatures rising a few degrees over
Saturday's highs.

Weak west to southwesterly flow will remain over the southwestern
u.S. Through the majority of the coming week with 500mb heights
rising slightly from 578-580dm to as high as 583dm on Wednesday.

Another weak upper level shortwave will bring a period of mostly
thin high clouds Monday night through early Wednesday, but these
clouds likely won't impact temperatures. Forecast highs for the
week fall mostly in the middle to upper 90s across the lower
deserts with little day to day variation.

Forecast confidence starting Friday drops considerably due to the
potential deep pacific low models keep advertising. Models are in
good agreement with the low developing off the west coast during
the middle part of the week and keeping the low fairly stationary
through Thursday, possibly into Friday. Model spread increases
starting Friday into next weekend with considerable differences
between the european and GFS operation runs and ensemble means.

Given the propensity of models being inaccurate with these deep
lows, forecast temperatures starting next Saturday are mostly a
blend between two extremes. If the pacific low end up lifting
northeast missing our region completely, temperatures will remain
well above normal. On the other hand if the low ends up close to
or into the desert southwest, then temperatures will dip closer to
normals and we will have to contend with another windy system.

Aviation
South-central arizona including kphx, kiwa, and ksdl and southeast
california southwest arizona including kipl and kblh:
no aviation concerns exist through our TAF period as only a few to
sct high clouds will pass by. For the phoenix area terminals,
diurnal winds will prevail with speeds generally staying at or below
10 kts. Further west at kblh, southerly winds will develop each
afternoon with light northerly drainage winds possible for a few
hours overnight (10-15z). Typical diurnal tendencies are expected
at kipl with speeds at or below 10 kts.

Aviation discussion not updated for amended tafs.

Fire weather
Tuesday through Saturday...

temperatures will warm to well above 90 degrees for lower desert
locations and into the upper 80's for the higher terrain in the
tonto nf. Minimum rh values will drop to near 10 percent with poor
to modest overnight recovery. Fortunately, the winds will stay
fairly light for much of the week. However, breezy conditions look
to resume next Saturday as another weather disturbance approaches
region.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code.

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.
