Area Forecast Discussion
National Weather Service Tucson AZ
323 AM MST Thu May 24 2018

.SYNOPSIS...Dry conditions will continue into the upcoming holiday
weekend and likely through the end of the month. Gusty winds will
return again this weekend as a low pressure system moves north of
the area. Afternoon highs will remain above seasonal normals today
and Friday before cooling a few degrees over the weekend.

&&

.DISCUSSION...High pressure aloft will strengthen today and Friday
in advance of a weather system approaching the California coast.
This strengthening of the high pressure ridge will result in high
temperatures about 4 to 8 degrees above normal. Readings will peak
Friday before the system moves inland and into the Great Basin
region by Saturday. Wind speeds will be on the increase as early as
Friday afternoon and more so Saturday as the weather system passes
north of the area. A Fire Weather Watch has been posted for the
White Mountains of southeast Arizona on Saturday. Please refer to
the Fire Weather section in this product for more details. The
system will also help lower high temperatures a few degrees over the
weekend into early next week.

&&

.AVIATION...Valid through 25/12Z.
Clear skies. Surface wind 10 kts or less early this morning, then
increasing out of W-SW at 10-15 kts after 24/17z. Winds diminish to
10 kts or less again after 25/03z. Aviation discussion not updated
for TAF amendments.

&&

.FIRE WEATHER...A few afternoon breezes are expected both this
afternoon and Friday afternoon. A low pressure system will approach
our area this weekend bringing a round of breezy/windy conditions on
Saturday, with critical fire weather conditions possible mainly
across the White Mountains. Thus, a Fire Weather Watch has been
issued for Saturday afternoon into early evening for northern
portions of Fire Weather Zone 153. Some afternoon breezes will
continue Sunday through the middle of next week, though not quite as
strong as Saturday. Generally seasonable temperatures through the
weekend with a more significant warming trend next week. No
precipitation expected.
