Area Forecast Discussion
National Weather Service Tucson AZ
156 PM MST Sun May 21 2017

.SYNOPSIS...Above normal high temperatures will continue through
much of the week. Tuesday and Wednesday will be warmest days while
Thursday and Friday see an uptick in wind speeds.


.DISCUSSION...Clear skies and above normal temperatures will
prevail through next week. A weak disturbance moving across the
Four Corners area could bring a few clouds to far eastern areas
Monday. High pressure will then build into southeast Arizona
Tuesday and Wednesday, when triple digit temperatures are likely
to return to the lower deserts.

The high will break down during the latter half of the work week
as troughing dominates the western U.S. This will bring an uptick
in winds Thursday and Friday. While dry conditions will continue,
high temperatures may drop to near seasonal averages by Friday.


.AVIATION...Valid thru 23/00Z.
Generally SKC with FEW-SCT clouds over the mountains near the
AZ/NM border mainly on Monday. SFC wind W/NW at 10-14 kts this
afternoon becoming ELY/SELY less than 10 kts overnight. W or NW
winds Monday afternoon will be slightly stronger than Sunday, in
the 12 to 20 kt range, especially east of KSAD-KFHU. Aviation
discussion not updated for TAF amendments.


.FIRE WEATHER...Dry conditions and above normal temperatures will
occur through Thursday. Expect an uptick in WNW 20-ft winds Monday
as the area is brushed by a weak disturbance moving across the
Four Corners area. 20-foot winds in eastern areas could briefly
reach 20 mph with higher gusts Monday afternoon. Otherwise, 20-ft
winds at or below 15 mph are forecast Tuesday and Wednesday.
Somewhat stronger west to southwest winds may occur Thursday and
Friday, especially near the Int`l border. A few spots in the
southern portions of fire weather zones 151 and 152 may reach
critical fire weather conditions Thursday and Friday.
