Area Forecast Discussion
National Weather Service Phoenix AZ
334 AM MST Tue Dec 19 2017
.SYNOPSIS...
Near to slightly above normal temperatures will persist through
mid-week amidst mostly clear skies. A strong storm system will move
into the Great Basin Wednesday and Thursday bringing an increase in
winds, and substantially cooler temperatures into the second half of
the week. However, rainfall chances will remain very low.
&&
.DISCUSSION...
The Southwest is currently in between storm systems, as the upper
disturbance that affected us over the weekend is moving into the
southern High Plains, and another more potent upper trough digs
across the Pacific Northwest. The latter feature will bring a
significant cooling trend and increase in winds beginning
Wednesday into the weekend. Prior to that, temperatures a few
degrees above normal with mostly clear skies and light winds will
prevail, bringing pleasant conditions for late December.
A general increase in southwesterly winds will increase area-wide
on Wednesday afternoon in response to surface pressure falls over
the central and northern Rockies. This will occur ahead of a
fast-moving cold front entering southeast California Wednesday
afternoon, which will demarcate an abrupt wind shift out of the
northwest into Wednesday evening. Advisory-level wind speeds are
forecast to occur across most of eastern Riverside County and
parts of Imperial County in the wake of the cold front, as 850-mb
flow strengthens to around 40 kt overnight. As such, a Wind
Advisory has been issued from 04Z-23Z Thursday, with the strongest
winds expected across the highest elevation locations of eastern
Riverside County, including Joshua Tree National Park. Breezy
conditions will spread across the remainder of the area on
Thursday, and patchy blowing dust will be possible.
The other big impact will be the much cooler temperatures in the
wake of the cold front, and high temperatures may struggle to get
out of the 50s in some lower desert locations, including the
Phoenix area. The coldest temperatures of the year are expected
Friday morning, and 30s will be common overnight in many
locations. A Freeze Watch has been issued for parts of southern
Gila County, where the first widespread freezing temperatures of
the season are expected. Similar temperatures can be expected into
Friday, before a gradual warming trend begins into the weekend as
upper ridging slowly expands eastward from the eastern Pacific.
Precipitation chances are expected to remain quite low throughout
the period given the over-land trajectory of the mid-week storm
system. The best shot for light precipitation may clip parts of
southern Gila County on Thursday, but potential will be quite
limited. The large-scale pattern will continue to favor dry
conditions for the foreseeable future.

.FIRE WEATHER...
Wednesday through Sunday...
Southerly winds will begin to pick up over SE California late on
Wednesday as a dry weather system approaches our area. A cold
front will then move through early Thursday switching winds to a
dry northwest flow. This will certainly bring a period of elevated
fire danger and will need to be watched closely as critical fire
weather thresholds could be met. Low 60s and upper 50s will be
common through the lower deserts Thursday and Friday while minimum
relative humidity bottoms out near 10-25% each afternoon. Winds
weaken dramatically on Friday as the system exits to our east with
wind speeds remaining relatively light through the weekend. A
subtle increase in temperatures and humidity look to occur over
the weekend but conditions remain largely unchanged.
