Area Forecast Discussion
National Weather Service Phoenix AZ
131 PM MST Sat Feb 14 2026

.KEY MESSAGES...

- Dry and warm conditions are expected this weekend with highs
  mostly in the mid to upper 70s across lower deserts.

- A strong weather system arriving Monday and Tuesday should
  bring better rain chances, breezy to windy conditions, and
  noticeably cooler temperatures.

- Another weather system clipping the area Wednesday will bring
  additional breezy to windy conditions and rain chances, and yet
  another drier system Thursday into Friday will help keep
  temperatures cooler through the end of the week.

&&

.SHORT TERM /TODAY THROUGH SUNDAY/...

Mid level WV imagery shows upper level ridging and dry air aloft
setting in over the Desert SW with H5 heights expected to be between
575-577 dam over the region today. This upper level ridging will
drive temperatures 4-6 degrees above normal across the lower deserts
today with afternoon highs in the mid to upper 70s. Additionally,
the region will be under mostly clear skies throughout this
afternoon into the early evening hours before cloud coverage begins
to increase by Sunday morning. With this increase of cloud coverage
Sunday morning's low temperatures will be slightly elevated, in the
upper 40s to mid 50s in the lower desert regions. By tomorrow
afternoon the center of the ridge will be to our east, centered over
New Mexico. However, continued SW flow aloft will push highs in the
mid to upper 70s with a few areas reaching 80 degrees.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...

A large blocking high is forecast by global models to sit over
the north-central Pacific and Bearing Sea through the next week to
week and a half. This positioning will allow a series of several
troughs to drop south along the U.S West Coast, bringing a few
rounds of precipitation and breezy to windy conditions to much of
the Western CONUS. Following the transient ridge this weekend, a
large Pacific trough/low will dip far enough south to tap into
some rich subtropical moisture and draw it up into the Desert
Southwest beginning Monday. IVT values are forecast as high as
400-500 kg/ms in southern AZ by late Monday, with PWAT values up
to 150-200% of normal. Models are in good agreement that the
central low pressure will only drop as far south as San Francisco,
CA before weakening and moving eastward inland, but with at least
a couple embedded, fast-moving, shortwave troughs rounding the
base of the parent trough. A very strong and deep upper level jet
streak will also set up on the south side of the trough, with
250mb wind speeds forecast as high as 150-170kts directly over
the local area.

Even though the coastal low stays well to the northwest of the
area and the first shortwave rounding the base of the low takes a
trajectory from LA up through southern NV, there will still likely
be considerable impacts across the Desert Southwest. Perhaps most
notably from wind, with the very strong jet overhead and low and
mid level southwesterly winds increasing up to 30-50kts. Despite
the track of the first shortwave, guidance still shows a fairly
strong cold front dragging through the area later Monday through
Monday night. This front, along with the jet dynamics, and strong
upslope flow through the AZ terrain look to be the primary forcing
mechanisms to drive scattered showers across the area. However,
the window for this all coming together may be relatively short,
especially for lower desert precip chances. Models show a mid and
upper level punch of dry stable air above 600mb, cutting off the
deep layer moisture, right around the same time, if not just
before, the front moves across the area.

Latest NBM continues to hone in this window for precipitation
with a west to east progression of PoPs, peaking around 70% in
south-central AZ Monday night that then falls to under 20% by
late-Tuesday morning. Given the shorter window and likely fast
moving showers, QPF is not very high, with amounts anywhere from
0.00-0.25" across the lower deserts. Higher amounts are likely to
occur across higher terrain areas north and east of Phoenix. Even
though this system will be a bit colder, accumulating snow levels
are likely to mostly stay above 6500 feet.

Tuesday, during the day, may bring some additional isolated
shower activity with the second aforementioned shortwave rounding
the parent trough and passing over the area. Another couple of
troughs then look to clip through the region Wednesday and again
Thursday into Friday, but the subsequent troughs will be working
with less moisture and the forecast tracks of the troughs are not
ideal for precipitation production across southern AZ and
southeast CA. Energy with the Wednesday trough may miss just
north. There is potential for light accumulating snow in western
Joshua Tree NP Wednesday if the lower level Pacific moisture can
penetrate the tall SoCal mountains. With tight pressure packing,
the strong jet streak overhead, and strong west to east flow
Wednesday, surface winds will likely be an impact again,
especially across southeast CA where downsloping enhancements may
lead to windy conditions and blowing dust.

Temperatures next week will easily be the coolest so far this
month, but the NBM only shows readings falling a few degrees below
normal starting Tuesday. Lower desert forecast highs from
Tuesday-Friday are mostly in the middle to upper 60s. Once drier
air and calmer winds develop later next week, some rural desert
areas may see overnight lows dip into the 30s.

&&

.AVIATION...Updated at 1730Z.

South Central Arizona including KPHX, KIWA, KSDL, and KDVT;
Southeast California/Southwest Arizona including KIPL and KBLH:
No aviation concerns are anticipated through the forecast period.
Winds will be light through the period (aob 6 kts) and follow
typical diurnal trends at all terminals. High clouds will move
into the region from W to E throughout the afternoon, becoming
widespread SCT by this evening.

&&

.FIRE WEATHER...
Warming and drying conditions will last throughout this weekend
with MinRH values around 20-30%. Sunday can expect occasional
breeziness, mostly in the western districts and higher terrain.
Multiple weather systems will then impact the region next week,
with greatest impacts expected Monday through Wednesday. The
weather systems will bring a chance for scattered rain showers,
mainly Monday night through Tuesday morning and on Wednesday.
Breezy to locally windy conditions are also expected, with gusts
up to 20-30 mph likely and 35+ mph in mountains and east-facing
downslope areas. Winds will be strongest Monday-Wednesday. MinRH
values are only forecast to improve to 25-35% through the first
half of the week, with gradual drying during the second half.
