Area Forecast Discussion
National Weather Service Tucson AZ
348 AM MST Wed Nov 14 2018

.SYNOPSIS...Periodically gusty winds will continue through
Wednesday coincident with unseasonably cool daytime temperatures.
Warming high pressure will gradually spread into the region during
the latter half of the week resulting in daytime temperatures
returning to near normal.

&&

.DISCUSSION...Gusty winds continued across the area overnight, with
a few mountain locations experiencing gusts to over 50 mph. A wind
sensor on Mount Hopkins reported a gust to over 80 mph. That said,
strong and gusty winds will hang around through this afternoon
before diminishing in speed this evening. A ridge of high pressure
aloft extending over California into the Great Basin will weaken
Thursday through the weekend. Before then, the high pressure ridge
will help daytime temperatures warm a few degrees to more seasonable
readings. This weakening of the high pressure ridge will open the
door for a weather system to enter southern California early next
week. This system will bring a chance of showers to the area around
Tuesday into Wednesday as it tracks through Arizona.

&&

.AVIATION...Valid through 15/12Z.
FEW-SCT cirrus at or above 20k ft AGL this morning becoming SCT-BKn
this afternoon. Gusty easterly winds diminishing at all sites except
KTUS today. Enhanced downsloping effects will allow for gusts up to
25 knots to persist into the early afternoon. Winds will finally
weaken below 12 knots at KTUS late this afternoon and continue at 12
kts or less tonight. Aviation discussion not updated for TAF
amendments.

&&

.FIRE WEATHER...
Periodically gusty east winds will persist today with speeds
slightly lower than Tuesday, but still some areas in excess of 25
mph - particularly over ridge tops, foothills and in portions of the
Tucson Metro. While the overall fire danger will remain low and
temperatures will stay much cooler than normal, the wind and very
low RH conditions could result in challenges with any grass/brush
fires during the afternoon hours. Temperatures will moderate into
the weekend with humidity levels increasing somewhat, yet remaining
quite low. The next chance of wetting rains is not expected until at
least the middle of next week.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...None.
