Area Forecast Discussion
National Weather Service Tucson AZ
211 PM MST Mon Sep 26 2022

.SYNOPSIS...Widely scattered afternoon and evening showers and
thunderstorms are expected across parts of southern Arizona Tuesday
through Friday. These are expected primarily from Tucson south and
west and over the White Mountains. The locally gusty easterly breeze
will continue through Tuesday then gradually ease as temperatures
slide back a few degrees by the end of the week.

&&

.DISCUSSION...Thunderstorms are popping on schedule this afternoon
time wise with a few more to the southeast than anticipated earlier.
Gotta love over-achieving thunderstorms! Development will continue
into the late afternoon hours with areas south and southwest of
Tucson getting in on the action. Tucson will see a storm or two in
the vicinity into the evening as well. There will be a gradual
dissipation after sunset this evening.

The setup for Tuesday through Thursday is the east to southeast flow
will continue to maintain above average atmospheric moisture levels
for late September, enough to allow for continued convection each
afternoon and evening around parts of southern AZ. The primary areas
will be south and southwest of Tucson where the greatest moisture
will be and over the White Mountains. Temperatures will creep lower
through Thursday but remain warmer than average.

Beyond that an upper level trough will scoot across the northern part
of the western US which is only expected to have a slight affect on
the area this weekend, basically shift the winds, cool the temps a
degree or two and dry out the mid levels of the atmosphere with a
significant reduction in convective chances. Beyond that there is a
good deal of variance in the models but overall the main theme should
be near average temperatures and likely dry conditions.

&&

.AVIATION...Valid through 28/00z.
SCT clouds AOA 10k ft MSL. WDLY SCT -SHRA/TSRA mainly W and S of
KTUS through 27/04Z although there is some potential for KTUS to be
impacted by a TSRA into early this evening. WDLY SCT -SHRA/TSRA
expected again Tuesday afternoon mainly south and west of Tucson.
SFC winds E-SE less than 10 kts during the late afternoon and
evening hours incrg to 12-18 kts with ocnl gusts up to 30 kts during
the morning and early afternoon hours. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...Scattered afternoon and evening showers and
thunderstorms are expected through Friday, generally from the Tucson
area south and west and over the Mogollon Rim country. The main
threat from the storms besides lightning will be strong and gusty
outflow winds. Breezy, east to southeast 20 foot winds will continue
through Tuesday before easing Wednesday into Thursday and generally
becoming light and diurnal thereafter.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...
