Area Forecast Discussion
National Weather Service Flagstaff AZ
325 AM MST FRI JUL 29 2016

.SYNOPSIS...Expect a cooling trend and increasing chances for
showers and thunderstorms heading into the weekend.

&&

.DISCUSSION...Significant storm activity continues over the Gulf of
California tonight. A surge is underway in Yuma, with a steady seep
of higher moisture values evident across the remainder of southern
Arizona and the Imperial Valley. This was expected and this will
pave the way for higher pops over the weekend and into next week.
Moisture will be drawn northward each day, due to outflows and a
trough passage well to our north that will improve streamlines.
Heights fall each day as well, which will weaken the cap that has
been in place for a few days.

Naturally, added moisture will lead to more storms, which will lead
to more cloud cover. Therefore, temperatures will begin to decline
today, with 5 to 10 degrees of cooling over the weekend.

&&

.AVIATION...For the 12z Package...Look for mainly VFR conditions
over the next 24 hours. Scattered afternoon thunderstorms over the
higher terrain from the Grand Canyon and Flagstaff southeast to the
New Mexico border. Elsewhere...isolated storms. Showers/Tstorms will
diminish after sunset. Aviation discussion not updated for TAF
amendments.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...None.
