Dry weather and unseasonably warm temperatures will persist
through the weekend with record highs likely by the middle of the
week. High pressure may weaken early next week bringing cooler,
although still above average temperatures.

Latest satellite imagery shows high clouds over the desert
southwest this morning that are pinwheeling around an unusually
strong high pressure system positioned west of baja california.

Over the course of the next 12 hours, this expanding ridge of high
pressure will push these high clouds north and east out of our
area as the deserts bake under mostly sunny skies. Latest 12z
sounding from tucson, yuma, and san diego indicates heights of
587, 589, and 591 dm, respectively. These height values indicate
the unusually warm airmass that is present and exceed the daily
records for all locations expect tucson. However, with the ridge
expanding eastward, record heights will likely be reached at
tucson tomorrow morning, if not this afternoon.

Increasing heights will undoubtedly bring warmer surface
temperatures across the desert southwest today, a reflection of
the warm air advection that is happening aloft as the ridge
marches eastward. Latest model guidance suggest temperatures will
soar into the upper 80s by thanksgiving, and for a few unlucky
locations (or lucky depending on your perspective), eclipse the 90
degree mark. The warmest desert temperatures, by a degree or two,
will be found in california due to their closer proximity to the
high pressure center. In any event, temperatures will be
unseasonably warm with many locations forecast to reach and
possibly exceed many heat related records (see climate section

Very warm temperatures will persist through the weekend as the
ridge will be slow to progress eastward. It isn't until early next
week do models show a pacific trough passing to our north
suppressing heights and bringing some relief (low 80s and
possibly upper 70s). However, even readings of those magnitudes
are still above average. As it stands right now, above normal
temperatures with absolutely no precipitation is forecast for
the foreseeable future.

South-central arizona including kphx, kiwa, and ksdl:
no aviation concerns for the next 24 hours as winds follow typical
diurnal tendencies. Winds will remain weak through early tomorrow
morning as skies gradually clear. A weak backdoor front will
bring enhanced easterly flow later Wednesday morning (17-20z) as
the atmosphere mixes down higher momentum air to the surface, but
easterly gusts should stay at or below 15 kts. Winds may stay
easterly all day on Wednesday but will be rather weak by the late
afternoon hours.

Southeast california southwest arizona including kipl and kblh:
clearing skies with very light winds, following typical diurnal
tendencies will prevail for the next 24 hours. No other aviation

Aviation discussion not updated for amended tafs.

Fire weather
Thursday through Monday: strong high pressure aloft will persist
across the lower deserts for the rest of the week and likely into
early next week as well. This will keep high temperatures well above
seasonal normals with the warmer deserts into the mid to upper 80s
most every day this week. Sunny to mostly sunny days are on tap
through Saturday, with some increase in mid and high clouds expected
Sunday into Monday. Expect relatively dry conditions as well with
minimum rh values each day running from the teens to around 20
percent. Winds each day will be on the light side, favoring typical
diurnal tendencies especially across the south-central deserts.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
