.SYNOPSIS...High temperatures will continue to be well above normal
today. Temperatures begin to lower Sunday into the middle of next
week, with near to slightly above normal readings by late next week.

&&

.DISCUSSION...Although High pressure aloft has started to shift east
of the region and the ridge axis is currently located across eastern
New Mexico, there will be one more day of well above normal high
temperatures today. Readings will top out around 10 degrees above
normal, with lower 80s from Tucson westward and highs in the 70s in
valley locations across eastern portions of the forecast area.

A series of systems will move across the northern tier of states
through the middle of next week, flattening the ridge and resulting
in zonal flow across the southwestern United States Sunday through
Tuesday. High temperatures will lower, but still remain above normal
as highs top out 4-7 degrees above normal Sunday through Wednesday.
A weak disturbance brushes northern Arizona Wednesday and Wednesday
night, resulting in a slight chance (10-15 percent) of precipitation
mainly across northern Graham/Greenlee counties. On the back side of
this disturbance late next week (Thursday and Friday), temperatures
will moderate but still be slightly above normal (1-3 degs) across
southeast Arizona.

There will be some breezy southwest to west winds across portions of
Cochise County Sunday afternoon, with winds speeds of 15-20 mph and
gusts to near 30 mph. The potential for more widespread breezy west
to northwest winds occurs next Wednesday as the disturbance moves
north of the area.

&&

.AVIATION...Valid through 24/12Z.
Clear skies to SCT clouds AOA 20k ft AGL thru 23/17Z, then
increasing high clouds with BKN-OVC clouds AOA 20k ft AGL thru the
remainder of the forecast period. SFC wind 10 kts or less, favoring
a SWLY thru NWLY direction during the afternoon/early evening hours
and variable in direction at other times. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...Dry conditions will continue through early next
week. There will then be a slight chance of showers mainly across
the White Mountains next Wednesday. High temperatures will be around
10 degrees above normal today, lowering back to 4-7 degrees above
normal Sunday through Wednesday and then 1-3 degrees above normal by
late next week. Min RH values will be 8-15 percent in the valleys
and 10-20 percent in the mountains through Sunday. Min RH values
will then increase 8-15 percent early to mid next week. 20-foot
winds will be 15 mph or less and terrain driven at most locations
through Tuesday of next week. Elevated southwest to west winds of 15-
20 mph and gusts to near 30 mph are expected Sunday across portions
of Cochise County, with the potential for more widespread elevated
west to northwest winds next Wednesday.
