.SYNOPSIS...Breezy to windy conditions will continue through this
evening as a low pressure system approaches from the west. Expect
cooler temperatures Thursday behind this system, then a warming
trend will prevail Friday into early next week.
.DISCUSSION...A low pressure system approaching the area today was
producing strong and gusty winds across the area. The strong wind
combined with dry conditions had prompted a Red Flag Warning for
much of southeast Arizona through 7 pm mst this evening. A wind
advisory was also in effect through 7 pm mst this evening for
southern sections near the International Border. The low pressure
system will pass through Arizona tonight and Thursday. This will
result in cooler daytime temperatures tomorrow and a slight chance
of thunderstorms in the White Mountains. The region will be in
between low pressure systems this weekend with dry conditions
continuing and daytime temperatures warming a few degrees. Models
showed a weak low pressure trough moving into the desert southwest
early next week with very little affect on the weather.
.AVIATION...VALID THRU 27/00Z.
Mostly clear skies will prevail through at least Thursday morning.
Sfc wind SW 15-25 kts and gusts 30-40 kts this afternoon, with the
strongest winds along the International Border. Wind easing to 10
kts or less this evening except remaining gusty over higher terrain.
Aviation discussion not updated for TAF ammendments.
.FIRE WEATHER...A Red Flag Warning is in effect until 7 PM MST this
evening for zones 150 through 152. Winds are expected to settle down
this evening across the valleys but will remain elevated across the
higher terrain as the low pressure system continues to approach.
Then during the day Thursday the low will be centered just north of
the Whites allowing for a lighter west wind and a small threat of
high based mostly dry thunderstorms over the White mountains.
Friday the winds will be much lighter. However, there is still a
small threat of mostly dry thunderstorms over the White mountains
during the afternoon hours. Then dry and slightly cooler than normal
conditions are expected this weekend and early next week with
lighter, more typical diurnal winds.
Red Flag Warning until 7 PM MST this evening for AZZ150-152.
Wind Advisory until 7 PM MST this evening for AZZ507-508-512-513.
