Update Updated aviation weather discussion.

Synopsis A weak weather system will move across the region
through Thursday. However, moisture will be insufficient for
rainfall. Slight cooling will take place through Thursday, but
temperatures will remain at or above normal. There will be off and
on periods of thicker high clouds Friday through Sunday before a
very slight chance of showers develops next Monday through

The center of the closed low that split from the main trough is
over the northern baja california peninsula, placing the western
portion of our forecast area under northerly flow and the eastern
portion under southwesterly flow. The axis is stretching from yuma
county northeastward into central maricopa county, with thicker
cloud cover to the west of the axis. GOES total pws is showing
less than .4 inches across our cwa, so as this low continues its
eastward progression precipitation chances will remain near zero.

However, we can expect a few high clouds to move through the area
today from time to time. Despite less cloud cover today, decreased
heights and slightly cooler temperatures aloft will lead to a
temperature drop today, with highs a few degrees cooler than
observed yesterday.

The low will weaken by early this morning around the time it gets
to northern mexico right as the main trough dives south towards
the four corners area. This will drive a dry cold front across our
forecast area overnight into tomorrow and bring breezy and drier
conditions to the region. Breeziest conditons will exist along and
west of the colorado river alley and along the higher terrain in
southwest and south-central arizona. The gustiest winds will be
observed along ridge tops in southeast california (gusts to 25 to
35 mph) and in southern gila county (gusts to 35 to 45 mph). Some
portions of these areas where greatest wind speeds will be
observed will be at wind advisory levels, however low coverage
precludes insurance of an advisory at this time. Due to cold air
advection behind the cold front, temps will be a few degrees
cooler tomorrow, with highs in the mid to upper 60s.

High pressure is still on track to quickly build behind this
trough Thursday night into Friday and persist through the the
early part of the weekend. This will cause a gradual warming
trend, with high temperatures rising from the mid upper 60s on
Friday into the upper 60s low 70s by the weekend.

Models continue to indicate an unsettled weather pattern Saturday
through the early part of next week. The most noticeable
difference compared to previous model runs is that there is an increase
in the amount of moisture expected to advect into the region.

Gefs plumes mean pws has shown an upward trend, with values now
approaching .7 inches across the forecast area by Monday. Thus, as
the front passes across our region Monday through Tuesday, there
will be slight precipitation chances, with accumulations expected
to be less than a tenth of an inch. Ridging will build behind
these series of systems by Wednesday and bring back dry
conditions and warmer temperatures.

South-central arizona including kphx, kiwa, and ksdl:
with no aviation concerns winds are expected to be light to light
and variable through the period and favor normal diurnal
headings. Skies will also be clear to mostly clear with some
occasional few mid to high level clouds.

Southeast california southwest arizona including kipl and kblh:
expect light to light and variable winds at kipl favoring the east
today and the west this evening and tonight. Light and variable
winds at kblh will become northerly and breezy by late afternoon and
early evening near 10-15kt. Skies will remain clear to mostly
clear with an occasional few mid to high level clouds.

Aviation discussion not updated for amended tafs.

Fire weather
Friday through Tuesday:
minimal fire weather concerns through the period. High pressure
will build over the region on Friday before an unsettled weather
pattern develops Saturday through the early part of next week.

Minimum afternoon humidity levels will be on the increase, with
values around 15 to 25 percent on Friday, rising into the 30 to 40
percent range Monday and Tuesday. Overnight recoveries will be
good to excellent. Wind speeds will remain light through Monday,
before some breeziness develops on Tuesday (mainly along ridge
tops in southwest az and southeast ca).

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.
