Area Forecast Discussion
National Weather Service Tucson AZ
408 AM MST Sat Nov 18 2017

.SYNOPSIS...Dry conditions will continue through next week.
Slightly cooler temperatures will occur this weekend and early next
week, with freezing temperatures possible Sunday and Monday mornings
for eastern valley locations. Daytime temperatures rebound quickly
to near record or record levels by Thanksgiving.


.DISCUSSION...High clouds have thinned considerably since last
night while a weak cold front continues to sag south across the
state. Cooler high temperatures this weekend but still running
above normal. The cooler airmass will also lead to colder
overnight lows with the coldest eastern valleys around freezing.
Upgraded the freeze watch to warning for both Sunday and Monday
mornings for portions of Cochise and Graham counties.

After the nice relative cool down this weekend, high temperatures
will ramp back up to well above normal values next week with
record or near record highs once again returning to the area
during the first half of the 4 day Thanksgiving holiday weekend.


.AVIATION...Valid thru 19/12Z.
Mostly clear skies with diurnal and terrain driven winds less
than 12 kts. Aviation discussion not updated for TAF amendments.


.FIRE WEATHER...Dry conditions are likely through the end of next
week. Lingering breeziness is possible east of Tucson into early
this evening as a trough departs the area, otherwise winds will
follow typical upslope/downvalley patterns through much of the
upcoming week.



 Freeze Warning from 1 AM to 8 AM MST Sunday for AZZ507>509.
 Freeze Warning from 1 AM to 8 AM MST Monday for AZZ507>509.
