.KEY MESSAGES...

* Isolated afternoon showers and thunderstorms will be possible
  again today in Northwest Arizona.

* Dry and breezy conditions are expected across most of the area
  today and tomorrow along with slightly below normal temperatures.

&&

.DISCUSSION...through Sunday.

A low pressure system will move into the Pacific Northwest today,
ushering in dry air form the southwest. Moisture will be scoured out
of the area over the next few days, but it will happen slowly and
enough moisture should remain to support isolated shower and
thunderstorm potential over high terrain Mohave County today and
tomorrow. Precipitation totals should be light. Afterwards,
precipitation is not in the forecast through the end of the week.

Breezy southerly winds pick up across much of the area on Monday and
Tuesday as the low pressure system pushes into the Pacific Northwest
and the pressure gradient tightens over the Southwest U.S. These
winds combined with the drying trend will result in elevated, but
not quite critical, fire weather concerns each afternoon, mainly in
southern Nevada. In addition to dry and breezy conditions, the lower
500 mb heights associated with this trough will result in cooler
than normal temperatures across our forecast area. Temperatures will
remain a few degrees cooler than normal through the end of the week.
