Update Updated aviation and fire weather discussions.

The streak of drier weather and above normal temperatures will
persist through the week with unseasonable warmth quickly
returning the next several days. In fact, record highs will be
likely by the middle of the week and into the long holiday

Overnight conditions similar to those last evening with thin high
clouds, and some patches of thicker cirrus, streaming across the
region from the northwest. Unseasonably strong ridging continues
to build into the region with the circulation center off the
central baja coast and ridge heights lifting the storm track and
upper jet well into the pac NW and western canadian provinces.

21 00z regional RAOB flights sampled 500mb heights in the mid 580s
on the north northwest periphery of the ridge center and 500mb
height progs paint low to mid 590s possible over northern baja,
colorado river valley and southern california by Wednesday and
Thursday. Values in this range climb into record-territory on
numerous parameters including ml height and temperature fields and
resultant surface temperatures. Cirrus cloud coverage will thin
and dissipate as strong ridge subsidence and displacement of the
upper jet occurs, clearing skies by Wednesday. Forecast
temperatures remain unchanged, painting one of the warmer (if not
the warmest) thanksgiving on record for many southwest locales.

Temperature records for both phoenix and yuma are referenced in
the climate section below.

Area of strong troughing moving through northeast pacific will
transition on-shore by the late week early weekend, flattening
ridge heights across the intermountain west. Subtle cooling will
result for much of the region, however still remain above late
november normals with temps still holding in the 80s. Highly
amplified wave pattern remains over the north american continent
into the weekend with broad ridging remaining over the four
corners on up through central canada. This will keep the current
dry streak count running and climbing north of 90 days since
measurable rain occurred at phoenix sky harbor. Rank for this
streak stands at the 39th driest as of Mon nov 20, tied with a
streak that ended in july 2010.

In the extended forecast, strong jet streak (180kt or stronger)
progged to develop off the asian continent should break down the
larger blocked pattern feeding several smaller shortwave and
progressive features into the north pacific. A more open pattern
should lend itself towards more forecast temperature variability
and some periods of elevated winds, however moisture parameters
still look lacking.

South-central arizona including kphx, kiwa, and ksdl:
high pressure aloft centered to our west will continue to give a dry
northwest flow aloft into the greater phoenix area today into
Wednesday. There will be periods of embedded high clouds, mostly
aoa 25k feet. We can expect bkn CIGS much of the time but cirrus
will often be on the thin side. Otherwise, gradients remain weak and
wind at the TAF sites will be light, favoring typical diurnal
tendencies. Much of the time, ksdl will be light variable or calm.

There are no aviation concerns today, tomorrow or for most of this
week at least.

Southeast california southwest arizona including kipl and kblh:
dry northwest flow aloft will persist today into Wednesday and there
will be periods of high cloud embedded in the flow with bases mostly
aoa 25k feet. There will be bkn CIGS at times with the high cirrus
often thin. Winds will be very light at the TAF sites next 24 hours,
often light variable or calm. No aviation impacts expected for at
least the next 24 hours.

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.
