Update Updated fire weather and aviation discussions.

The high pressure system over the region that produced above normal
afternoon temperatures will weaken tonight as several weather
systems move into the western states. Although dry weather is
forecast, gusty afternoon southwest winds can be expected through
Saturday. Also, afternoon temperatures on the lower deserts will
cool into the 90s, or below normal temperatures. Dry weather with
warmer temperatures are expected beginning Sunday and continuing
through next week.

Considerable high level cloudiness spans much of the az and SE ca
international border this early morning, moving SW to ne. Upper
ridge axis that brought us a stretch of warm weather has cleared
well to our east this morning as broad troughing spans from the
central canadian provinces, down through the northern rockies and
through northern ca. Subtropical jetstreak enhancement began last
evening over baja california, evident in cirrus blowoff over the
baja spine streaming into the area overnight. Mid-level height
falls and 1000-500mb thicknesses have begun to trend downward as
troughing sinks and turns to swing into the area. Combination of
height falls and upper jet proximity have created gusty pass level
winds across southeast california already this evening and those
will persist as well as expand down into the lower desert
elevations with the strongest winds focused along and west of the
colorado river valley. Gusts for the western CWA and southwest
arizona will range 30 to 40 mph by the afternoon and 20 to 30 mph
for the south-central az deserts. Visibility and air quality
impacts are anticipated in the dust sand prone areas, especially
across southeast california. Subtle CAA and theta-e ridging will
support a temperature cool down starting today with 8 to 12
degrees of cooling anticipated. Temperatures will cool further
still as troughing persists over the great basin and southwest for
the end of the week and early weekend, with slightly below normal
temperatures forecast through Saturday.

High amplitude ridging will build back over the west coast over
the weekend and transition back into the southwest for Sunday and
Monday. Desert temperatures will head north of triple-digit
readings again.

By late Monday and into early next week, high amplitude wave
pattern over the pacific and western CONUS will begin to be
undercut by a strong pacific jet. A piece of energy becomes
cutoff from the upper jet streak storm branch, developing off-
shore northern baja Tuesday. To our east, high pressure
circulation will develop over tx through the 850-700mb layer. Low
and mid-level flow will become southerly in nature, drawing
moisture northward into the eastern portions of arizona. Slight
chances for afternoon and evening thunderstorms remains for the
eastern most portions of southern gila county through midweek.

Breezy south to southwest winds are also expected to reappear
Tuesday and Wednesday afternoons. Temperatures will trend slightly
cooler with more atmospheric moisture and lower heights in the
region again, near late may early june normals.

South-central arizona including kphx, kiwa, and ksdl:
southeast california southwest arizona including kipl and kblh:
westerly winds will increase today area-wide, with the strongest
gusts expected across southeast california, where gusts to near 30
kt are forecast. Winds will be slightly weaker over metro
phoenix, but still expecting gusts to 25 kt to develop by 19z and
persist into the late evening. Winds should eventually weaken by
08z at kphx kiwa and switch towards the east. West winds will
persist throughout the entire TAF period at kipl. Periods of high
clouds will persist throughout the day, but should begin to clear
out overnight.

Aviation discussion not updated for amended tafs.

Fire weather
Saturday through Wednesday:
lighter wind speeds are expected this weekend as a pronounced
area of high pressure builds over the great basin. Temperatures
will also be near or slightly below seasonal normals on Saturday,
with highs in the low-mid 90s. Warmer temperatures will occur by
Sunday, with highs near 100 degrees, and will remain similar each
day through the middle of the week. Winds will also be generally
light during this period.

A weak pacific low pressure system will develop and move eastward
towards the southwest, and could result in a slight chance for
thunderstorms across the higher terrain of east-central arizona,
including southern gila county on Tuesday and Wednesday afternoons.

However, confidence in any rain or lightning potential is still
low this far out.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with 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 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.
