Area Forecast Discussion
National Weather Service Flagstaff AZ
245 PM MST Thu Jul 10 2025

.SYNOPSIS...Expect hot temperatures to continue at least through
the weekend and into early next week. Moisture will be sparse, with
only isolated activity through the weekend, primarily over the
eastern portions of Arizona.

&&

.DISCUSSION...Our ridge continues to flatten just a little bit and
retrograde westward into the coming weekend. This will continue to
cap our atmosphere and any moisture that may have a chance will be
driven southward by northerly streamlines. NBM guidance continues to
be driven by climo and we continue to tamp down PoPs, mainly in the
first few days. The bottom line, don`t expect very much for at least
the next 3-5 days, except for more heat. Some longer range guidance
indicates the possibility of an easterly wave and a weak s/wv trough
that may ramp up our activity for a few days, but confidence is low.
