Synopsis
Slow moving low pressure over arizona will continue to bring
showers to portions of the state today, although drier air and
warmer temperatures will gradually take hold tomorrow through the
end of the week. Rain chances will once again return this weekend
as moisture moves into the area, resulting in another round of
showers, cloudy skies, and below normal temperatures.

Discussion
Early afternoon satellite imagery reveals upper level low pressure
over arizona, with an extensive amount of cloud cover across the
northern 2 3rds of the state. Phoenix remains right on the edge
of the thickest cloud cover, whereas locations along interstate 8
from gila bend to yuma and westward to EL centro are seeing
virtually cloud-free skies. Not surprisingly this has produced
quite a temperature gradient across the area with 20z temps in the
low mid 60s around phoenix whereas temps were approaching 80 in
southeast california.

The forecast for the rest of the afternoon evening hours will be
one of decreasing rain chances and decreasing cloud cover. Little
to no rain is occurring across the area at present although a few
wraparound showers are still possible until sunset (per hrrr and
nbm solutions). From there, expect clouds to dissipate with only a
few clouds lingering north east of phoenix. This should allow
temps to fall well into the 50s tonight with some of the normally
cooler areas approaching the upper 40s.

Wednesday through Saturday should see drier and slightly warmer
air as shortwave ridging takes hold across the area. Some degree
of southeasterly upslope flow could bring increased clouds to the
mountains east of phoenix but not enough to warrant a mention of
rain chances. Look for desert temps to steadily climb through 70s
into the 80s and even close to 90 in spots by the weekend.

Looking at the latter half of the weekend into next week, the
deterministic GFS and ecmwf, along with their ensembles and other
post-processed guidance suggest that a moist plume of air will be
drawn northward into arizona from mexico, resulting in an
unsettled pattern and increased rainfall chances. Pops remain well
above normal for late october for next week.

Aviation
South-central arizona including kphx, kiwa, and ksdl:
clouds remain in place across the valley with CIGS around 6500ft.

Expect CIGS to gradually thin out later this afternoon and lift to
a broken mid deck around 15kft before scattering out overnight.

Winds should remain light but out of the east for the duration of
the forecast period.

Southeast california southwest arizona including kipl and kblh:
north winds expected at both sites along with clear mostly clear
skies through at least Wednesday afternoon.

Aviation discussion not updated for amended tafs.

Fire weather
Friday through Tuesday:
increased temperature will prevail through the first half of the
weekend, although a slight decrease is forecast Sunday into next
week. Moisture will move into the area resulting in increased
humidities and rain chances. There will be a noticeable increase
in winds on Saturday as the moisture moves into the area,
especially in the mountains east of phoenix, but otherwise winds
should remain at 15-20mph or less area-wide.

Spotter information statement
Spotters should follow standard reporting procedures.

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.
