Area Forecast Discussion
National Weather Service Tucson AZ
327 PM MST Thu May 23 2024

.SYNOPSIS...
Seasonably warm and dry conditions will continue for the next few
days with breezy conditions on tap each afternoon. Saturday will
see the strongest winds as a weak disturbance moves through this
weekend. Highs will climb and potentially exceed 100 early next
week as weak high pressure ridge builds over the region.

&&

.DISCUSSION...
Latest water vapor imagery continues to depict broad zonal flow
across the western states, driven between a series of disturbances
over the rockies and high pressure aloft centered over northern
Mexico. Pattern will sustain breezy afternoons and near to slightly
above normal high temperatures for this time of year over the
next few days. Temperatures will approach and potentially exceed
100 early next week, in response to a weak ridge of high pressure
aloft building. Strongest winds will be on Saturday, in response
to a weak upper level trough passage over the region.

Ensemble guidance continues to favor building an upper level ridge
across the Rocky Mountain chain and four corners by the middle of
next week. Outcome will sustain reduced afternoon winds and favor
lowland high temperatures from the mid to upper 90s across
Cochise, Graham, Greenlee and Santa Cruz counties, to lower 100's
across Pima and southwestern Pinal county.

&&

.AVIATION...Valid through 25/00Z.
SKC through 24/03Z. Then SCT-BKN 250 between 24/03Z and 24/12Z
for all areas. SKC returns after 24/14Z. SFC winds W-SW 12-18 kts
with gusts to 25 kts through 24/02Z then light and variable
overnight. SFC winds SW 15-22kts with gusts to 30kts after 24/19Z.
Aviation discussion not updated for TAF amendments.

&&

.FIRE WEATHER...
Dry conditions with breezy afternoons at times will continue
Friday and especially Saturday. Minimum RH values to the single
digits in valleys with poor to fair overnight recoveries remain
forecast. Temperatures In an environment supportive very low fuel
moistures Saturday for the foreseeable future, the combination
20-foot sustained wind speeds to 20 mph or more Saturday should
favor the development of Critical Fire Weather Conditions across
the lowlands in Cochise, southern Graham, Greenlee and northeast
Pinal counties. Seasonably warm temperatures will continue through
the weekend, with hotter afternoons on tap early next week.
