Area Forecast Discussion
National Weather Service Flagstaff AZ
258 AM MST Wed Sep 18 2024

.SYNOPSIS...Slightly below normal temperatures and breezy conditions
continue for the rest of this week. Only a slight chance of showers
for late Friday and Saturday over northern Arizona, but mostly dry
conditions otherwise. A benign and warmer weather pattern develops
for next week.

&&

.DISCUSSION...There are two areas of low pressure over the western
part of the US this morning. One low is over Montana and Wyoming.
This the low that brought windy conditions over northern Arizona
on Monday. Another low is quickly following on the first`s heels
and is currently just along the coast near the OR/CA border. The
second low will move south along the coast reaching the LA Basin
by Thursday afternoon before moving east to the Las Vegas area by
Friday afternoon. The low will weaken and eject to the Four
Corners area by mid-day Saturday. A ridge will then build over the
Great Basin and extend southwestward well in into the Pacific
through Tuesday.

This pattern will bring daily south to southwest winds in the 15
to 25 mph range, followed by crisp and cool nights as the winds
decrease.

As the low transitions across Arizona later this week and into
the weekend, a few light showers may develop. Additionally, high
temperatures will dip a few degrees below average.

High temperatures will warm to above average as high pressure
returns next week, for a early fall warm- up.
