.KEY MESSAGES...

- Dry and tranquil weather conditions with well above normal
  temperatures will prevail across the region through early next
  week.

- A more unsettled weather pattern is likely to develop later
  next week with cooler temperatures and increased precipitation
  chances

&&

.SHORT TERM /TODAY THROUGH SATURDAY/...
Unseasonably warm weather remains in place to finish out the
workweek as afternoon readings will top out around 10-15 degrees
above normal. This is thanks to a strong ridge situated over the
Desert Southwest with the center of the high positioned to the
west of the Baja Peninsula. This patttern will persist into the
weekend allowing for continued well above normal temperatures as
well as dry, tranquil weather conditions. Afternoon temperatures
on Saturday are expected to be around 2-3 degrees cooler than
today as highs across the lower deserts are forecast to top out
in the mid to upper 70s.

&&

.LONG TERM /SUNDAY THROUGH LATE NEXT WEEK/...
Upper-level ridging will continue to dominate the overall weather
pattern across the Desert Southwest through the first half of
next week, continuing the dry and tranquil conditions.
Temperatures will continue to remain unseasonably warm as
afternoon highs top out in the upper 70s to around 80 degrees
across the lower deserts. There continues to be a high probability
(>70% chance) of Phoenix at least tying to even breaking daily
record highs both on Sunday and Monday according to the latest
NBM.

A more unsettled weather pattern then is likely to ensue heading
towards the middle and latter portion of next week as the upper-
level ridge shifts eastward into the southern Plains, allowing a
deep trough to build just off the west coast. The deterministic
and ensemble model suite continue to diverge significantly on the
overall strength and positioning of the trough as it deepens off
the west coast, leading to a low confidence forecast heading
towards the latter portion of next week. Abundant moisture is
likely to spread northeastward from the subtropical Pacific into
the region from late Tuesday into Wednesday, with both the EPS and
GEFS showing PWATs rising above 200% of normal. Guidance is
showing a lead shortwave out ahead of the main trough moving
through the Great Basin, which combined with the moisture that
will be in place, could generate shower activity across portions
of the region during the day on Wednesday. Precipitation chances
after Wednesday will then be dependent on the overall strength and
positioning of the main trough off the west coast as it
eventually migrates inland. With more abundant cloud cover and
potential precipitation as well as the decreasing heights aloft,
temperatures are likely to cool down later next week by about 5-10
degrees from the readings earlier in the week but still remain
above normal.

can be expected throughout the TAF period. Winds will remain light
with subtle diurnal directional shifts. Extended periods of
variable and calm conditions will be common as well.

.FIRE WEATHER...
High pressure across the region will continue to promote dry and
tranquil weather as well as unseasonably warm temperatures, 10 to
15 degrees above normal, into early next week. Winds will
generally be light under 15 mph. Afternoon MinRHs will range
between 20-35% with good overnight recoveries of 40-70%. A more
unsettled pattern in form of cooler temperatures and increased
precipitation chances is likely later next week.
