.SYNOPSIS...Scattered to numerous showers and thunderstorms will
continue over the region through Sunday. Some stronger storms may
contain large hail, damaging winds, and very heavy rainfall, which
could lead to flash flooding. Conditions dry out by early next week.
&&
.DISCUSSION...Low pressure will continue moving SSE toward Yuma
today, where it will then stay through Saturday night. The southern
progression of this low is allowing for more easterly flow over
Arizona, which is currently moving the convective boundary westward.
As a result, we expect more of Yavapai County to become involved
today, especially along the I-17 corridor.
This will continue to be the case Saturday as the low entrains more
moisture, with convection eventually reaching the Lower Colorado
River. Shear, helicity and CAPE values over parts of central and
western Arizona today and Saturday continue to support isolated
severe. Roughly the next 24 hours continues to support isolated
rotating cells.
By Sunday, the low opens up and ejects. We expect another day of
numerous showers and thunderstorms Sunday, but the air mass will
have become fairly cold and stabilized at that time, so the threat
of severe will diminish.
Much drier westerly flow sets up in the wake of this ejecting low
and PoPs approach zero from Monday onward.

OUTLOOK...Saturday 27/18Z through Monday 29/18Z...VFR to MVFR
conditions expected. Scattered to numerous SHRA/TSRA during the

diminish west to east Sunday evening. Winds SE-SW 10kts daytime,
light and variable overnight.
&&
.FIRE WEATHER...Friday and Saturday...Expect thunderstorm coverage
to shift southwestward today, with eastern Yavapai County and the
Mogollon Rim seeing enhanced activity. Storm activity will decrease
overnight, but may stay active over the far southern portions of the
district. Scattered storms then continue on Saturday. Winds outside
of any thunderstorm activity will be southerly at 5 to 15 mph.

thunderstorms continue through Sunday, with much drier and slightly
warmer conditions for Monday and Tuesday. Winds outside of any
