.SYNOPSIS...Mainly dry conditions are anticipated over northern
Arizona today with an increasing chance of showers and isolated
thunderstorms overnight and on Tuesday. Lingering moisture will
then lead to a continued chance of showers and isolated storms
through Friday. Drier air from the west will move in over the
weekend. Look for near normal temperatures through the period.


Moist and mild conditions will develop this work week over much
of the area, with an increasing chance of precipitation through
the middle of the week as southerly fetch between a low pressure
system off the coast of California and a ridge of high pressure
over the West Texas.

Topographical enhancement will allow for showers to develop over
the higher terrain of the Mogollon Rim and White Mountains tonight
and into Tuesday. As that moisture moves across Northern Arizona,
precipitation changes will increase across the area, with the best
chance of widespread precipitation occurring Tuesday and

A large scale closed low will move over the Pacific Northwest
towards the end of the week, as this system moves inland the high
pressure ridge over Texas will flatten out in response and
southerly flow will give way to a more zonal pattern limiting
moisture transport through the weekend.


.AVIATION...For the 18Z package...Winds will be generally light
for most locations tonight, though locally gusty northeast winds
will continue, mainly southwest of KFLG. Breezy winds will become
easterly this afternoon. Chances for showers southeast of KSOW,
with the potential for precipitation shifting north and west
Monday Night and Tuesday. Aviation discussion not updated for TAF
