Area Forecast Discussion
National Weather Service Phoenix AZ
245 PM MST Mon Dec 5 2016

.SYNOPSIS...
Dry weather with seasonably temperatures, and passing high clouds at
times are forecast the remainder of this week and weekend.

&&

.DISCUSSION...

Tonight through Monday...

A series of fast moving Pacific weather systems are forecast to move
through the western states this week and weekend. A dry cold front
will become nearly stationary over northern AZ, the geographical
limit where most of the cold air will remain located. Therefore dry
west to northwest flow aloft, with occasional high clouds, and near
seasonably normal temperatures are forecast across our forecast
area, southeast CA to south central AZ, through the remainder of the
week and weekend.

.AVIATION... South-Central Arizona including KPHX, KIWA, and KSDL:

No aviation concerns through this TAF period. Winds will stay very
light, primarily aob 8 kts, and follow typical diurnal headings.
