Area Forecast Discussion
National Weather Service Tucson AZ
335 AM MST Sat Apr 22 2017

.SYNOPSIS...Very warm and dry weather will persist into at least
early next week. Occasional high clouds, and gusty afternoon winds
at times will occur as systems brush by to our north. Stronger winds
will be possible especially late next week along with a slight
chance of showers and thunderstorms across the White Mountains.

&&

.DISCUSSION...The upper ridge axis, which extended from central
Nevada too off the northern Baja coast this morning, will move
across the state today resulting in slightly warmer daytime
temperatures. These well above normal high temperatures will
continue Sunday into Monday then a cooling trend thru the end of
next week. Most of next week will see gusty afternoon winds which
will bring some fire weather concerns Mon thru Wed. A deeper trof
passing across northern Arizona on Thursday may bring a slight
chance of showers to mainly the White Mountains. High temperatures
by the end of next week could be below normal.

&&

.AVIATION...Valid through 23/12Z.
SKC thru valid pd. Sfc wind WLY/NWLY at 10-14 kts with some gusts to
around 25 kts during the afternoon and early evening hours.
Otherwise, sfc wind will be terrain driven at less than 10 kts.
Aviation discussion not updated for TAF amendments.

&&

.FIRE WEATHER...Dry conditions and above average daytime
temperatures will continue into next week. Minimum daytime
humidities will be in the single digits and teens. For the most
part, 20-foot winds will follow normal diurnal trends at less than
15 mph with daily afternoon and early evening gustiness. A few
systems passing north of the region next week may bring breezy to
windy conditions creating critical fire weather conditions
mainly near the NM border and through the Gila River Valley.
