Area Forecast Discussion
National Weather Service Tucson AZ
257 PM MST Fri Nov 4 2016

.SYNOPSIS...Some clearing from the west tonight with a general
drying trend over the weekend. A weak system could bring another
chance of showers in eastern areas around mid week. Daytime highs
will be close to or slightly above seasonal averages for early
November, with overnight lows seasonably cool.

&&

.DISCUSSION...The low has lifted just north of our area near the
central Arizona border with New Mexico. A partial clearing trend
with some cumulus popping up on recirculated boundary layer
moisture. Greenlee county will still be going for a few more
hours, but most of the activity will be north and east of our
area. Patchy fog possible in eastern areas Saturday morning.

The latest HRRR shows diminishing dew point trends, and along
with the partial clearing, a few spots will drop a degree or two
lower tonight. Tonight and Saturday night we will see chilly
seasonal temperatures with coldest isolated eastern valley
locations in Cochise county dropping into the middle to upper 30s.

Daytime highs will climb a few degrees as a shortwave ridge phases
across the area from the west over the weekend, but not far from
seasonal averages for early November. However, the main strength
of the ridge will probably stay west of our area with impulses
sagging back into the front of the ridge and into New Mexico. Some
easterly spill-over from that could bring a few showers to eastern
areas the second half of the new week.

&&

.AVIATION...Partial clearing from the west with isolated showers
and thunderstorms possible near the New Mexico border. Brief
patchy fog possible overnight for eastern sites including KSAD
and KDUG. Normal diurnal wind trends through the period.

&&

.FIRE WEATHER...A few showers in mainly far eastern areas tonight
and Saturday, otherwise a general drying trend from the west into
early next week. Normal diurnal wind trends. 20-foot winds will
generally be less than 15 mph, except for some afternoon
gustiness.

&&

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