.SYNOPSIS...Above normal high temperatures return to southeast
Arizona today and will continue for the next seven days with
Wednesday being the warmest day of the upcoming week.


.DISCUSSION...Abundant sunshine and the warmest afternoon in over
a week or more is in store for southeast Arizona today. Tucson`s
high temperature forecast of 98 degrees would be a degree warmer
than last Saturday the 13th when Tucson topped out at 97.

A few clouds could build up over the Chiricahua and White
Mountains late today, but a deeper moisture layer will exist
farther east in New Mexico where a few thunderstorms could occur.

No changes to the going forecast at this time.


.AVIATION...Valid thru 22/18Z.
Generally SKC with FEW-SCT clouds this afternoon over the
mountains near the AZ/NM border. SFC wind ELY/SELY 8-12 kts this
morning becoming WLY/NWLY at 10-14 kts this afternoon. Wind speeds
will diminish to less than 10 kts this evening. Aviation
discussion not updated for TAF amendments.


.FIRE WEATHER...Dry conditions and above normal temperatures will
occur this week. 20-ft winds will generally be at or below 15 mph
with some afternoon gusts due to strong daytime heating through
Tuesday. Slightly elevated west to southwest winds may occur for the
second half of the work week, especially near the Int`l border. A
few spots in the southeast portion of fire weather zone 152 may
reach critical fire weather conditions Thursday and Friday.


.PREV DISCUSSION...A clear sky prevailed across SE Arizona this
morning which will lead to another bright sunny day with high
temperatures today returning to above normal territory for the
first time in almost a week. Warmer temperatures during the week,
peaking on Wednesday, as high pressure aloft builds over the area.
Slightly cooler with an uptick in winds to end the week as
weather systems pass by to our north. Some mid level moisture will
be edging west across southern NM this afternoon and Monday
afternoon cloud build- ups near the AZ/NM state.
