Area Forecast Discussion

.UPDATE...

.KEY MESSAGES...

- A weak cold front will slide across the forecast area resulting in
breezy conditions for portions of the region today and Wednesday.

- Dry and mostly tranquil conditions will prevail through the
weekend with above normal temperatures.

&&

.SHORT TERM /Today through Wednesday/...
Water vapor satellite imagery and objective analysis early this
morning reveal a deep trough digging into the Plains and high
pressure across Mexico and the Baja. The high pressure to the south
will start to build into the Desert SW today and into tomorrow
resulting in H5 heights rising into the 588-590 dm range, peaking
late tonight. This will lead to temperatures warming a couple
degrees today. Afternoon high temperatures today are forecasted to
be in the low 90s across the lower deserts and in the mid 80s across
the higher terrain. The aforementioned trough digging into the
Plains will push a weak backdoor cold front through the region later
today and into Wednesday. Despite H5 heights being around 588 dm
tomorrow, this backdoor cold front will result in temperatures
cooling a degree or two on Wednesday.

Additionally, the backdoor cold front will lead to areas of breezy
to locally windy conditions across the CWA from this afternoon and
continuing into Wednesday. No products will be needed as wind gusts
are expected to stay below Advisory criteria (< 40 mph). Wind gusts
of 20-25 mph are expected this afternoon and evening across the
lower Colorado River Valley and the higher terrain to the north and
east of Phoenix. Wind gusts will then pick up (20-30 mph) during the
overnight hours into Wednesday morning across the higher terrain
areas of south-central and SW AZ. The highest gusts will be along
the ridgetops where gusts upwards of 35 mph are possible. Wind gusts
will then taper off Wednesday afternoon and evening.

&&

.LONG TERM /Thursday through Tuesday/...
On Thursday a weak shortwave trough will move through the region.
This will lead to lowering heights aloft with H5 heights falling to
around 581-585 dm. This in turn will result in temperatures cooling
a couple degrees, but remaining above normal. By the end of the
workweek and beginning of the weekend afternoon high temperatures
are forecasted to fall into the upper 80s to around 90 degrees
across the lower deserts and into the upper 70s to mid 80s across
the higher terrain. By the beginning of next week high pressure will
build back into the Desert SW. With high pressure building back in
H5 heights will rise back into a 589-591 dm range. This will result
temperatures warming a couple of degrees. With afternoon high
temperatures forecasted to be in the low 90s across the lower
deserts and in the mid 80s across the higher terrain. Despite the
minor changes in the overall weather pattern over the next week,
temperatures will remain 5-8 degrees above normal and dry conditions
will persist.

.AVIATION...Updated at 1705Z.

South Central Arizona including KPHX, KIWA, KSDL, and KDVT:
A non-typical wind trend will be the primary weather issue through
Wednesday afternoon under clear skies. E/NE wind directions will be
preferred for much of the time frame, however an attempt for
directions to become more NW late afternoon/early evening may
briefly cause a period of N/NW cross runway winds. Increased speeds
of east winds with gusts near 20kt may also be possible Wednesday
morning/early afternoon with conditions approaching LLWS criteria
around sunrise prior to achieving mechanical mixing.

Southeast California/Southwest Arizona including KIPL and KBLH:
No major weather issues should exist through Wednesday afternoon
under clear skies. North winds will be common through the period
with some tendency for KIPL to back to westerly during the
overnights. Some daytime gustiness may be common especially at KBLH.

&&

.FIRE WEATHER...
Temperatures will fluctuate a few degrees up and down through the
week, but remain around 5-8 degrees above normal for this time of
year. MinRHs will be around 10-15% for the lower deserts to around
20% for the higher terrain areas through the week, with good
overnight recovery. Wind gusts of 20-25 mph are expected across the
Lower Colorado River Valley and higher terrain in the eastern
district this afternoon and evening. Winds will then pick up across
south-central and SW AZ during the overnight hours tonight into
Wednesday morning, where gusts of 20-30 mph are expected. Gusts
upwards of 35 mph are possible along ridgetops. Winds will then
taper off through Wednesday afternoon and evening. With winds
returning to their typical diurnal tendencies and minimal afternoon
gustiness on Thursday.
