Area Forecast Discussion
National Weather Service Flagstaff AZ
926 PM MST THU JUL 28 2016

.SYNOPSIS...A cooling trend with increasing chances for showers
and thunderstorms is forecast from Friday into next week.


.DISCUSSION...A few strong storms impacted northern Arizona
today. The strongest storms were observed south of the Mogollon
Rim. A report of 1.5 inch hail was received around 4pm near the
city of Walker in Yavapai County.

Storm activity has largely diminished across northern Arizona
this evening. A few storms remain in portions of far southern
Coconino and Yavapai Counties, but this activity is expected to
dissipated of the next hour.


.PREV DISCUSSION /329 PM MST/...Strong high pressure over
northwestern Arizona will weaken as low pressure moves into the
Pacific Northwest. This will weaken the cap over our area and
allow for decent return flow that will begin to transport surge
moisture northward over the weekend, resulting in increased
thunderstorm coverage in the coming days.

In short, expect cooling temperatures and increased monsoon
activity for the remainder of the seven day forecast period.


.AVIATION...For the 00z Package...Expect mainly VFR conditions
over the next 24 hours. Look for a round of scattered afternoon
thunderstorms along and south of the Kaibab Plateau and Mogollon
Rim. Elsewhere...isolated storms are forecast. Aviation
discussion not updated for TAF amendments.


.FGZ WATCHES/WARNINGS/ADVISORIES...Excessive Heat Warning until 11 PM MST this evening FOR AZZ005-
