Update Updated aviation and fire weather discussions.

Synopsis
Warm and overall dry conditions will last into the early weekend
as temperatures continue to hit several degrees above average each
day. A couple of very weak weather disturbances today and
Wednesday may allow for a few showers across the higher terrain
of eastern arizona. A pacific low pressure trough in combination
with some potential for tropical moisture affecting the desert
southwest will bring a return of chances for showers and
thunderstorms Sunday night into early next week.

Discussion
Weak cyclonic westerly flow aloft continues across the desert
southwest with mid level moisture remaining across the eastern
half of arizona. This moisture will be slow to exit the area
allowing for additional slight chances for mainly afternoon
showers across the high terrain both today and again on Wednesday.

Locations across the south-central arizona lower deserts may see
periods of clouds during this time, but no chance of any rain.

Further west, skies will remain clear to mostly clear.

After a fast moving shortwave trough dives southeastward through
the four corners area into new mexico on Wednesday, higher heights
aloft will edge eastward into the desert southwest. These higher
heights will be in response to an amplifying ridge that gets
squeezed between a deep pacific low off the west coast and the
broad troughing over the central u.S. Warming conditions will take
place Wednesday and Thursday as highs easy surpass 100 degrees
across the lower deserts both days. Thursday and Friday look to be
the warmest days of the week before the ridge breaks down
starting Friday. High temperatures across the deserts of southeast
california and southwest arizona may approach excessive heat
criteria in localized areas as readings may hit 106-108.

A complex scenario is shaping up for this weekend into early next
week after the pacific low off the west coast opens up and the
main low center moves ashore into northern california Saturday
night. Things get complicated when we may have to worry about a
tropical system (tropical depression twenty-e) potentially
approaching from the south southwest Sunday into Monday. The
operational GFS has been fairly consistent showing some sort of a
tropical system moving into the desert southwest, but has mostly
been alone until the last couple models runs. A majority of the
00z GFS ensemble members now also support a potential tropical
system nearing the region while the 00z european still keeps the
system well out over the pacific until it falls apart. Persistent
broad troughing over the western u.S. Into early next week should
at least allow for some tropical moisture if not a full fledged
tropical system to get drawn northward near or into the desert
southwest. Confidence in timing and the extent of moisture are
still low at this point, but we have expanded pops some for Sunday
night through early next Tuesday. This will definitely be
something to watch over the next several days as it could bring a
significant rain event to the region.

Aviation
South-central arizona including kphx, kiwa, and ksdl:
broken cloud deck near 10-12 thousand feet will persist this
morning before breaking up by this afternoon. Winds will follow
typical diurnal wind directions, remaining less than 8 kt. No
aviation weather concerns are anticipated.

Southeast california southwest arizona including kipl and kblh:
little to no aviation concerns through Tuesday afternoon with
mostly clear skies. Winds to follow typical diurnal trends at
kipl while remaining mostly from a southerly direction at kblh.

Aviation discussion not updated for amended tafs.

Fire weather
Thursday through Monday:
temperatures will remain several degrees above seasonal normals
into the weekend with readings pulling back closer to average next
week. Dry weather will predominate all districts through Saturday.

Minimum afternoon humidity levels will range from the teens in
lower elevations to around 25% at higher terrain north and east of
phoenix with a trend towards higher values through the weekend.

Overnight recovery will be fair to good. Wind speeds should remain
typically light for early autumn with somewhat stronger southerly
winds and more pronounced gustiness late in the week.

Richer moisture appears likely to move northward into the
southwest Sunday and Monday, which may bring increasing chances
for showers and thunderstorms, along with potentially cooler
temperatures and increased humidities.

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.
