.SYNOPSIS...A slow moving weather system will bring scattered
rain and mountain snow showers to the area into tonight. This
will be followed by cold overnight temperatures this weekend into
Monday. It will be dry next week and becoming much warmer by
midweek.

&&

.DISCUSSION...Scattered light valley rain and mountain snow
showers since late last night have been occurring mostly north of
a Sells to Tucson to Clifton line. Rainfall amounts have mostly
been less than a tenth of an inch with localized amounts up to a
quarter of an inch across parts of Pinal county. No snow reports
have been called into the office as of this writing but some of
the mountain cameras show some minor accumulation. Scattered
showers will continue today into tonight before ending from west
to east. Maintained the Winter Weather Advisory above 6500 ft
until early Saturday morning for the mountains of Graham and
Greenlee counties. Depending on how fast clouds clear up tonight
into Saturday morning, could see some patchy fog develop,
especially across eastern Pinal county.

Colder air mass settles in over the weekend with cold overnight
lows with Sunday morning the coldest. As the previous discussion
mentioned, it still appears that a few of the outlying areas of
the Tucson metro and the colder areas in southeast Pinal county
may approach freezing Sunday morning.

High pressure next week will bring warmer temperatures with highs
Tue thru Fri running, depending on location, 6 to 12 degrees
above early December climo.
