Cool conditions will continue to affect the region through the
weekend with several passing weak weather systems. Breezy
conditions will continue this afternoon and evening across
southeast california creating some areas of blowing dust. A few
showers may develop on Friday, mainly across northern arizona, as
a weak storm system affects the southwest. A slight warming trend
is expected early next week before another weather system moves
into to the area early next week bringing another chance for
showers along with cooler temperatures.

Satellite trends show low-level moisture advecting eastward
towards the coastal ranges of southern california, with some
cumulus development noted more recently across parts of imperial
and eastern riverside county. Wind speeds have gradually increased
across southeast california, with blythe reporting gusts near 30
mph this afternoon. Still expecting the strongest wind speeds to
materialize across parts of jtnp, where a wind advisory remains in
effect for western portions of the park through 10 pm pst.

The primary vort MAX associated with a deepening upper trough over
the western u.S. Is centered near the central sierra. The current
forecast trajectory of this system will keep it focused across far
northern arizona into utah, which has been the case for most of
the season. This will bring the upper jet along the basal portion
of the trough through central arizona, focusing the strongest jet
dynamics across northern arizona. As a result, any precipitation
will likely be confined from the phoenix area north eastward, with
amounts remaining on the light side. Can't rule out a few showers
developing Friday afternoon evening across the phoenix area.

In the wake of the Friday storm system, the pattern will remain
active across the southwest, with the next in a series of storm
systems more progressive and positioned farther to the north as it
quickly moves across northern arizona Sunday morning. This should
have little effect on our temperatures, paving the way for a
warming trend into Monday, with a brief return of the 70 degree
mark expected.

Still looking at a potentially more significant, but still
uncertain, storm system developing across the southwest into early
parts of next week. The ECMWF deterministic solution still favors
a stronger, closed low which would be ideal for a longer duration
of elevated precipitation chances, while most mean ensemble
guidance maintains an open wave across the southwest. Regardless,
should see another cool down with this system, and the return of a
chance of precipitation Tuesday into Wednesday. There does appear
to be a little more moisture associated with this storm system
than the preceding systems, and a closed low solution would be
beneficial for advecting more moisture north eastward into the
forecast area. For now, maintaining chances of precipitation
peaking late Tuesday into Wednesday across most of the region.

South-central arizona including kphx, kiwa, and ksdl:
through about 18z tomorrow, aviation concerns will be minimal,
thereafter winds will start to pick up and bkn cloud decks around
5 kft will move into the area.

Today and tonight winds will follow normal diurnal headings and
remain light with mostly clear skies. Winds will shift to the west
tomorrow morning around 16 17z and be a bit breezy with sustained
wind speeds near 10 to 15 kts and gusts to 20 kts. An increase in
low-level moisture will allow bkn cloud decks near 5 kft to move
into region during the mid to late morning hours.

Southeast california southwest arizona including kipl and kblh:
winds will become breezy to windy out of the west. Wind gusts to
25 kts at both kipl and kblh are likely through early evening with
some slackening of gusts during the overnight hours tonight. Wind
speeds will pick up again early in the morning, especially at
kipl, where gusts to 30 kts are possible. Skies to remain clear to
mostly clear through about 12 13z. Thereafter, bkn cloud decks
near 5 kft will move into the region from the west.

Aviation discussion not updated for amended tafs.

Fire weather
Saturday through Wednesday:
drier westerly flow aloft will develop Saturday into early next
week, allowing temperatures to gradually climb and approach
seasonal normals by Monday. Minimum rh values will drop into the
12 to 18 percent range through Monday with improvement into the
20s by next Tuesday. Winds will be fairly light Saturday through
next Monday. A weather system is likely to affect the region for
the middle of next week bringing increasing chances for rain and
breezy conditions.

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.
