.SHORT TERM /Today through Monday/...
Current objective analysis reveals a Rex block setting up over
the western tier of the CONUS which will be the main weather focus
over the next few days for the Desert Southwest. The area of low
pressure associated with this type of setup is currently centered
over the Baja Peninsula and has helped set off some breezy to
locally windy conditions for parts of the region due to the
enhancement of the local pressure gradient. Elevated gusts are
likely to persist into Monday, especially for foothills and
higher elevations areas, as the gradient only relaxes slightly.
Observations of 25-35 mph will be common for these areas with
locally higher gusts closer to 40 mph possible for the highest
ridge tops east of the Phoenix metro. However, due to the limited
scope of advisory level winds, no wind products will be issued.
After a chilly end to the previous week, temperatures will
gradually climb back toward near and above normal levels by the
start of the upcoming workweek as lower desert highs rebound into
the upper 60s and lower 70s.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Ensemble members are in good agreement that the rex blocking pattern
will hold through at least the beginning of the upcoming workweek
before the low finally starts to break down during the middle to
latter half of the workweek. At the same time, the high pressure
will maximize. As the high strengthens throughout the week, heights
aloft will gradually rise resulting in gradually warming
temperatures. The warmest temperatures of the week are forecasted
for the end of the workweek, coinciding with when the high is
forecasted to maximize. Afternoon high temperatures on Tuesday are
forecasted to be in the low to mid 70s across the lower deserts and
in the 60s across the higher terrain. Then for the latter half of
the week high temperatures warm into the mid to upper 70s to near 80
degrees across the lower deserts and in the mid 60s to low 70s
across the higher terrain. Temperatures in this range will be 7-10
degrees above normal for the middle of January. Additionally morning
lows will be on the rise, going from the 40s (30s) across the lower
deserts (higher terrain areas) on Tuesday to the upper 40s to low
50s (low to mid 40s) to end the workweek. Dry conditions will also
continue through this upcoming week.

.AVIATION...Updated at 0005Z.

South Central Arizona including KPHX, KIWA, KSDL, and KDVT:
Gusty E`rly winds will subside this evening, but sustained speeds
will mostly remain around 5-10 kts through the night. While east
winds will be preferred throughout the day Monday, it would not be
unusual for KPHX to experience a few hours of variable or light
SW winds around sunrise Monday morning. Marginal LLWS impacts are
expected again tonight through early Monday morning, with shear
magnitudes around 20-30 kts. E`rly wind gusts up to 15-25 kts will
return again Monday morning beginning around 17Z, but will
gradually subside through the afternoon. Skies will remain mostly
clear through tonight followed by SCT cirrus during the day
Monday.

Southeast California/Southwest Arizona including KIPL and KBLH:
No major weather issues will exist through Monday. Confidence is
very good that a northerly wind component will be preferred
through the period with a tendency for directions to back to
westerly at KIPL this evening/tonight before returning northerly.
Clear skies will eventually give way to FEW to SCT cirrus
beginning Monday morning.

.FIRE WEATHER...
Temperatures will be near to slightly above normal today and will
gradually warm through the workweek. Temperatures will go well above
normal by the middle of this coming week. MinRH values of 15-35% and
overnight recoveries of 40-70% will continue through this coming
week. Breezy to locally windy conditions will continue today. The
highest gusts will be across the eastern districts, especially
ridgetops, where gusts in excess of 40 mph are likely through the
early afternoon. Wind speeds will return to more seasonable levels
this evening and continue into next week. Winds will maintain a
northeasterly to easterly prevailing direction today and possibly
into early next week.
