Area Forecast Discussion
National Weather Service Phoenix AZ
1020 PM MST Mon May 29 2023

.Update...Updated Aviation

&&

.SYNOPSIS...
Dry conditions along with near to below normal temperatures will
prevail through next weekend. Breezy to locally windy conditions
are expected during the afternoon/evenings through at least mid-
week, with the strongest winds expected across portions of
Imperial County. As a couple of weather disturbances move across
the Desert Southwest through the middle to latter half of the
week, a cooling trend is anticipated with highs across most of the
lower desert communities only topping out in the lower 90s.

&&

.DISCUSSION...
Latest RAP analysis indicates the short-wave ridge has shifted
eastward into New Mexico. Meanwhile, further upstream a compact
upper low is evident in water vapor imagery off the central
California coast. Between these two systems, a dry southwesterly
flow predominates across the region. With the increased meridional
component to the flow, temperatures are somewhat lower than this
time yesterday across southern California, while further east
across central and eastern Arizona, warmer conditions prevail.

As we head through the middle of the week, the aforementioned upper-
level low will be drifting eastward across southern California
through northern Arizona. As it does so, the pressure gradient
will be tightening somewhat across the region, resulting in breezy
to locally windy conditions, particularly during the
afternoon/evening hours. The strongest winds are anticipated
Tuesday and Wednesday, especially across the western half of
Imperial County, where gusts between 35-45 mph are likely. The
strong winds could result in localized areas of blowing dust as
well. Elsewhere, into Arizona, wind gusts are likely to peak
between 20-30 mph.

A cooling trend is expected on Wednesday across most of the
region as heights aloft lower in response to the approaching
upper-level low, with highs across most of the lower deserts
likely only topping out in the lower 90s. These values will be a
good 5-8 degrees below normal for this time of the year. Similar
temperatures are expected for Thursday and Friday as another
weaker shortwave trough moves across the region, reinforcing the
lower heights aloft. A warming trend is then anticipated as we
head into next weekend as heights aloft rise with temperatures
warming back to near normal, which for early June is around the
century mark across the lower deserts.

.AVIATION...Updated at 0520Z.

South-Central Arizona including KPHX, KIWA, KSDL, KDVT:
Afternoon breeziness tomorrow will be the main aviation concern
during the TAF period. Winds tonight will be light with speeds
primarily aob 10 kts. By late tomorrow morning, winds will pick up
a more S'rly component, before an increase in speed during the
early afternoon hours. Continued veering is expected over the
course of the afternoon before winds eventually settle out W/SW by
early evening. Gusts during the afternoon and evening hours are
expected to be around 20-25 kts. Skies are anticipated to remain
clear over the course of the period.

Southeast California/Southwest Arizona including KIPL and KBLH:
No aviation concerns are expected through tomorrow morning.
Tonight, winds will be light out of the S at BLH, while IPL will
continue with light winds out of the W. By tomorrow afternoon,
speeds will increase with gusts 20-25 kts at both terminals, with
IPL seeing higher gusts around 35 kts by tomorrow evening. These
enhanced gusts at IPL will have the potential to generate areas of
blowing dust, which could inhibit visibility at times. Skies are
expected to remain clear through the period.

&&

.FIRE WEATHER...
Seasonably dry conditions are expected to prevail through the
period along with daily afternoon/evening breezes. Enhanced winds
are anticipated Tuesday and Wednesday as a weather disturbance
moves across the Desert Southwest with afternoon/evening gusts
ranging between 20-30 mph across most areas, with western Imperial
County likely to observe stronger gusts ranging between 35-45 mph.
MinRH values are expected to range between 8-15%. The combination
of the enhanced winds as well as the low RH values will result in
an elevated fire danger threat.

Below normal temperatures are expected later this week along with a
slight uptick in moisture. Thereafter, a warming trend as well as
slightly drier conditions are anticipated next weekend. Winds
will be weaker during the second half of the week through next
weekend, although the typical diurnal breezes will persist.
