Area Forecast Discussion
National Weather Service Flagstaff AZ
1020 AM MST WED AUG 03 2016

.SYNOPSIS...Expect frequent and widespread storm activity through
Thursday. Deep moisture will mean that stronger storms will contain
torrential rainfall. A slow drying trend begins Friday, lasting
through the weekend and into next week.

&&

.DISCUSSION...An active morning already, several MCVs are rotating
around an upper low that will drift north through Arizona through
Thursday. A strong gravity wave emanated from the Four Corners last
night and this is already into central Yavapai County. Activity
along this wave will be the focal point for stronger storms today.
Secondary areas may form in Apache County and near the Utah border
later today as skies clear. Mogollon Rim country may be to worked
over and rain-cooled to generate fresh convection today.

We have expanded the Flash Flood Watch to include all of our CWA
through this evening. The watch may be extended into Thursday when
the afternoon package goes out. The mid-levels begin to dry out on
Thursday and Friday, with some added shear. This may be a recipe for
stronger and more organized storms, before the drying really settles
in by the weekend.

Pops will be tweaked for today as well, to better reflect the
mesoscale trends stated above. No other updates are planned at this
time.

&&

.AVIATION...For the 18Z package...BKN-OVC150 over much of northern
Arizona with ISOLD-SCT -SHRA/TSRA and ISOLD MVFR conditions in
RA/BR. Some terrain obscured. An area of -RA/RA from KFLG-KP23-K40G
is moving south with TSRA on the southern edge. This area will
slowly move south through 23Z and impact KPRC and KSEZ. TSRA will
develop over other areas of northern Arizona until around 02Z. SCT
-SHRA could continue through the night. Aviation discussion not
updated for TAF amendments.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...Flash Flood Watch through this
evening all of Apache, Coconino, Northern Gila, Navajo and Yavapai
Counties.
