Area Forecast Discussion
National Weather Service Flagstaff AZ
350 PM MST FRI AUG 26 2016

.SYNOPSIS...Expect a chance of thunderstorms and cooler than
normal daytime temperatures through the weekend as a weak low
pressure system moves into Arizona. A drying and warming trend may
start early next week, before increasing moisture and storm chances
return by mid week.

.DISCUSSION...A trough of low pressure is dropping south through the
Great Basin this afternoon while deep monsoon moisture (1-2 inch
Pwat) resides over Arizona. Scattered showers and thunderstorms
produced hail and localized minor flooding across northern Arizona
today. The low will provide enough lift for some storms to continue
through the night tonight...especially northwest of a Bagdad-Flagstaff-
Four Corners line.

Saturday is expected to be active again as the trough moves over the
state. Sunday will see a decrease in storm coverage.

Drier and warmer weather is forecast Monday into Tuesday with the
best chance of storms near the AZ/NM line. Later Tuesday into
Thursday, a trough over the west coast could pull deeper moisture
back north into the area increasing our thunderstorm chances.


.AVIATION...For the 00z package...Thunderstorms and showers
diminishing to isolated after 03z. Monsoon moisture will remain in
place so Look for another round of scattered showers and
thunderstorms on Saturday. Away from storms light winds with scatter
to broken ceilings 5-7 kft above ground level. Aviation discussion
not updated for TAF amendments.
