Area Forecast Discussion
National Weather Service Tucson AZ
312 AM MST Mon Oct 23 2017

.SYNOPSIS...Record or near record high temperatures can be expected
today. Temperatures will gradually decrease the rest of the week,
but remain elevated above normal. Dry conditions will also prevail,
with a period of strong easterly breezes on Tuesday into early
Wednesday.

&&

.DISCUSSION...Record and/or near record high temperatures can be
anticipated today as a ridge of high pressure aloft peaks in
amplitude. Latest models continued to show this ridge of high
pressure remaining over the region for most of the week. After today
though, height and thickness values will lower through the week.
This will result in a gradual lowering of high temperatures.
However, high temperatures will stay well above seasonable normals.
Needless to say, dry conditions can be anticipated this week as
well. Strong and gusty east to southeast winds will develop Tuesday
into Wednesday in response to a tight surface pressure gradient.

&&

.AVIATION...Valid thru 24/12Z.
Clear skies and SFC wind generally NELY-SELY less than 12 kts
through the forecast period. Aviation discussion not updated for TAF
amendments.

&&

.FIRE WEATHER...Dry conditions will persist through the week.
High temperatures will warm and surpass record values today and
reach near record values again on Tuesday before a gradual cooling
trend begins. Light easterly winds today will strengthen from the
east/southeast on Tuesday into Wednesday, with gusts to 25-35 mph at
times. A few locations in Fire Weather Zone 151 may briefly reach
critical fire weather thresholds late Tuesday morning into the early
afternoon hours. Winds will turn west/northwesterly Thursday and
Friday and become breezy once again, especially for areas east of
Tucson.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...None.
