Area Forecast Discussion
National Weather Service Phoenix AZ
130 PM MST Wed Nov 30 2016

&&

.SYNOPSIS...

Dry northerly flow aloft will result in below normal temperatures
and low humidity through Thursday. Another dry and cold weather
disturbance is forecast to move into the region later Friday and
Friday night. A slight chance of showers are forecast over portions
of south central Arizona, generally from Phoenix eastward Friday
evening. Gusty north winds will also resume along the Colorado River
Valley Friday. Mostly clear skies and warmer temperatures are
expected this weekend through early next week. A turn toward colder
and more unsettled conditions is possible for the middle of next
week.

&&

.DISCUSSION...

Tonight through Thursday...

Dry northwest flow with nearly cloudless skies and low humidity will
continue this period. Mostly light winds are forecast, with
afternoon temperatures about 5 to 6 degrees below normal. Overnight
lows tonight will remain below normal as well, with the coldest
lower desert locations once again seeing lows near the freezing mark.

Friday and Saturday...

Little change in forecast thinking is expected this period. Models
continue to forecast another deep and cold low pressure system to
move into Arizona on Friday. Antecedent dry air over the region, and
the fact that this approaching disturbance will track inland from
Canada and away from the Pacific, suggests very little in the way of
increased deep humidity and precip. However, disturbances undergoing
a rapid southward latitudinal change usually intensify (conservation
of vorticity).  Therefore anticipating increased upper level
dynamics, and a strong upward vertical motion field over central AZ,
these factors should wring out every water molecule in the
atmosphere, enough to produce considerable mid level clouds and
threatening skies Friday afternoon and evening mainly from Phoenix
eastward. Therefore slight chance precip will continue across
southern Gila County late Friday afternoon and night. Additionally,
another episode of gusty north winds will develop down Colorado
River Valley Friday and Saturday. Clearing skies are expected
Saturday afternoon as the low pressure system continues to deepen
into Mexico throughout the day.

Sunday and Monday...

Dry northwest flow aloft will develop over the region this period.
Nearly cloudless skies are expected with afternoon temperatures
approaching seasonal normals.

Tuesday and Wednesday...

Confidence is increasing that a turn towards cooler and more
unsettled weather is on the way during this period. The GFS, EURO,
and many of their respective ensemble members are in remarkable
agreement that a very deep long-wave trof will be dropping southward
into the western US during this period as strong ridging builds
northward into the Gulf of ALaska. A very cold airmass, with its
origins from eastern Siberia is forecast to be pulled eastward and
southward across the Bering Sea into Alaska and NW Canada, then into
the Western US. Although the bulk of this very cold air will likely
remain north of our cwa, there is a decent chance that enough of it
will make its way into our cwa to produce a significant drop in
temperatures, with lower desert highs potentially struggling to make
their way out of the 50s. Although moisture will likely be limited
with this system, there now appears that there will be at least
enough moisture/dynamics to at least justify introducing some slight
chance pops over the higher terrain of South-Central AZ.

&&

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

With no aviation impacts throughout the period expect light winds
favoring typical diurnal patterns and occasionally becoming light
and variable or calm. Light northwesterly winds will also be favored
from mid to late afternoon. Skies will be clear to mostly clear with
periods of FEW-SCT high clouds until very late tonight when BKN high
cloud CIGS near 25kft. could move in.

Southeast California/Southwest Arizona including KIPL and KBLH:

Winds will be light and variable and also tend towards normal
diurnal patterns. Skies will be clear to mostly clear with
occasional FEW-SCT high clouds at 25kft. No aviation impacts are
expected.

Aviation discussion not updated for amended TAFs.

&&

.FIRE WEATHER...
Friday through Tuesday:

Elevated Fire Danger for southeast CA and the lower Colorado River
Valley Friday and Saturday afternoons. A dry low pressure storm
system will move through the region from the north beginning on
Friday bringing strong gusty winds and drier air out west and only a
slight chance of rain showers to the south central deserts and the
eastern high country on Friday and Saturday. As a result, Joshua Tree
N.P., higher elevations of eastern Riverside County CA, northern
Imperial county CA and the lower Colorado River valley can expect
several hours of elevated fire danger on both Friday and Saturday
afternoons and early evenings. Very breezy to windy northerly winds
of 20-30 mph sustained with gusts of 32-46 mph will develop from
southeast CA to southwest AZ on Friday morning through Saturday
evening. Min RH values of 12-17 percent on Friday over southeast CA
will fall to 8-15 percent on Saturday before beginning a gradual
rebound on Sunday. The south central deserts and the higher
elevations out east will have lighter winds and min RH values of
20-30 percent or better with excellent overnight recovery. Expect
breezy westerly winds with gusts of 15-22 mph to develop on Tuesday
across the region with the next cold low pressure system.

&&

.SPOTTER INFORMATION STATEMENT...
Spotters are encouraged to report according to standard criteria.
Spotter reports of wind and dust may be needed Friday across
southeast CA and southwest/west AZ.

&&

.PSR WATCHES/WARNINGS/ADVISORIES...
