Area forecast discussion, Nov 10, 2:44 AM MST, 10 hours 18 minutes before
Area Forecast Discussion
National Weather Service Phoenix AZ
244 AM MST Sat Nov 10 2018
.SYNOPSIS...
A dry air mass will remain parked over the Southwest through next week,
as a cold front sweeps southward late Sunday and Monday. A period
of breezy to windy conditions can be expected, especially on
Sunday, along with slightly below normal temperatures. Towards the
middle of next week, stronger high pressure will return to the
area resulting in temperatures warming back near normal.
&&
.DISCUSSION...
Broad northwesterly flow remains firmly entrenched across most of
the CONUS this morning, featuring the coldest air of the season
across the Plains and Midwest. On the western periphery of this
flow regime, high pressure over the Great Basin will gradually
weaken in between storm systems traversing eastward. Across
Arizona and southeast California, a very dry air mass is in place
with surface dewpoints ranging from the lower teens to 30s in most
locations. This is allowing for cool overnight temperatures to
materialize amidst generally light winds. Daytime temperatures
will be very close to seasonal normals today.
A fast-moving shortwave trough will quickly progress generally
southward on Sunday, bringing an attendant low-level cold front
across Great Basin into the lower Colorado River Valley on Sunday
and early Monday. This will result in an increase in wind speeds
across the western deserts, with sustained wind speeds of 20-25
mph with stronger gusts possible. Some areas may approach advisory
thresholds, but for now, it appears too marginal to warrant
special highlights. Fire weather concerns may also increase given
the very dry air mass that will likely be in place. Precipitation
chances are expected to be minimal, with any substantial forcing
for ascent and moisture positioned across far eastern Arizona and
New Mexico.
Cooler temperatures will also advect into the region Sunday and
Monday, with high temperatures expected to fall into the low 70s
each day - a few degrees below seasonal normals. The potential for
the first freezing temperatures of the season will also exist
across parts of southern Gila County on Tuesday morning. By late
next week, upper ridging will gradually weaken while slowly
shifting eastward, bringing a warming trend with temperatures back
to near seasonal normals, and pleasant weather for mid-November.
&&
.AVIATION...
South-Central Arizona including KPHX, KIWA, and KSDL: Easterly winds
will prevail this morning with gusts up to 15 kts mid morning. The
switch to west this afternoon should be later than usual although
confidence on the timing is lower than usual. However, expect it to
occur within an hour or two from the time indicated in the TAF.
Clear skies will continue with no other aviation concerns.
Southeast California/Southwest Arizona including KIPL and KBLH: Very
light winds are expected at the terminals today with extended
periods of variable winds this afternoon. Light westerly flow will
likely return this evening while skies remain clear.
Aviation Discussion not updated for amended TAFs.
&&
.FIRE WEATHER...
Monday through Friday:
High pressure will generally predominate across the Desert
Southwest, resulting in drier than normal conditions. Below normal
temperatures are also anticipated, though a gradual warming trend is
likely through the week. Meanwhile, the pressure gradient will
weaken throughout the week, resulting in a gradual decrease in
average winds. Nevertheless, locally breezy conditions are
possibly, particularly early Monday as a low pressure system across
the Four Corners ejects eastward.
