.SHORT TERM /Today through Monday/...

Current GOES Mid-level WV imagery shows broad troughing across the
west coast with the core of the system over the coastline between
Washington state and Canada. This system will continue pushing
inland through the weekend, tightening the pressure gradient causing
breezy to windy conditions over the weekend. Winds will be strongest
today as there are also multiple shortwaves embedded in the upper
level low and will work their way through the trough over the
weekend. Peak gust speeds will be in the southwestern corner of
Imperial Valley, however, widespread windy conditions will be
present across the Lower Colorado River Valley area as well. Due to
this wind advisories will remain in effect through today along the
Lower Colorado River Valley areas, and through Sunday night in the
far southwestern portion of Imperial County. Expect winds between 25-
35 mph and gusts up to 55 in these areas. These winds can make
travel difficult for high profile vehicles and may produce localized
dense blowing dust. Otherwise, in conjunction to the elevated winds,
very dry conditions will promote elevated to critical fire weather
conditions, especially in the eastern higher terrain/ Gila County.
That being said a Red Flag Warning remains in effect through Sunday
evening.

This large, and seasonably strong troughing feature will also bring
temperatures trending to below normal starting Sunday and into early
next week. H5 heights today will be between 588-591 dam dropping to
between 582-587 dam by Sunday. Resulting in temperatures 5F-10F
below normal, quite the treat for late June.

&&

.LONG TERM /Tuesday through Saturday/...

Once the Pacific trough settles over the Western CONUS negative
height anomalies will remain in place over the Desert SW through
early to mid week at the latest. The negative height anomalies
will keep temperatures between 98F-103F or around 4F-7F below
normal for this time of year. Guidance shows temperature beginning
to climb back towards normal by Thursday as the trough begins to
be displaced by the subtropical high building to the region`s SE,
returning H5 heights to near seasonal normal. By the next weekend
afternoon highs will yet again be in the 105F-110F range.

.AVIATION...Updated at 1740Z.

South Central Arizona including KPHX, KIWA, KSDL, and KDVT:
The primary aviation weather concern will be gusty southwesterly
winds during the afternoon and early evening, under clear skies.
Winds have already veered out of the south southwest this morning
and will remain southwesterly through the rest of the day into the
overnight hours. Late afternoon/early evening gusts will peak
around 25 kts. Gusts will subside by 03-05Z across the terminals,
remain generally below 10 kts overnight, with moderate confidence
in a later than usual, brief SE switch around sunrise at KPHX.
Winds are then likely to shift south then southwest within a few
hours after sunrise Sunday and develop gusts by late morning.

Southeast California/Southwest Arizona including KIPL and KBLH:
Strong, gusty winds out of the SW or W will continue to be the
main aviation concern through the next 24 hours under clear skies.
Gusts between 25-35 kts will be common, peaking during the
afternoon at KBLH and late afternoon/evening at KIPL. Temporary
surface VIS restrictions due to lofted/blowing dust will be
possible with the stronger gusts, though confidence is too low to
include MVFR or lower VIS in the TAF. Winds will gradually
decrease through the overnight period, possibly becoming light and
VRB for a period early Sunday morning at KBLH.

&&

.FIRE WEATHER...
Elevated to critical fire danger will continue today due to low
humidity, very warm temperatures, and afternoon upslope/upvalley
breezy conditions. Red Flag Warnings have been issued today through
Sunday for much of the area. Expect MinRHs to stay close to 5-15%
for the next several days. Winds will again increase this evening
with gusts in the 20-35 mph range and locally higher over higher
terrain areas. Winds are likely to peak on this evening with
gusts commonly reaching 25-40 mph. These windy and dry conditions
will combine with the very dry fuels to create a risk of extreme
fire behavior. Temperatures will cool this weekend reaching
slightly below normal levels starting Sunday and lasting into
early next week. Winds are expected to gradually diminish next
Monday into Tuesday.
