Area Forecast Discussion
National Weather Service Tucson AZ
228 AM MST Wed Jan 24 2018

.SYNOPSIS...High pressure aloft will result in a warming trend
through Thursday, with dry conditions and breezy winds at times. The
warming trend will be briefly interrupted Friday with several
degrees of cooling before resuming this weekend.

&&

.DISCUSSION...Dry and warm weather will be the main story into
next week. Our flow will continue to weaken at most levels as a
broad based ridge dominates the desert southwest today. Surface
high pressure building through the central and southern Rockies
will enhance the easterly flow across our area today, helping
another 6 or 7 degree jump in temperatures today. Quite dry, with
precipitable water values near or below 1/5 of an inch and surface
dew points in single digits (on both sides of the zero line).

A trough passing north of our area will knock several degrees off
of daytime highs Friday. After that interruption, afternoon highs
will climb to levels around 10 to 12 degrees above average by
Sunday (possibly near 80 around the greater Tucson area).

&&

.AVIATION...Valid thru 25/12Z.
Clear skies thru the period. SFC wind ELY/SELY generally 8-15 kts.
The strongest winds will occur late this morning, with a few gusts
to near 20 kts possible. Aviation discussion not updated for TAF
amendments.

&&

.FIRE WEATHER...Dry conditions will prevail over the next week.
Easterly 20-ft winds around 15 mph are expected today. Westerly to
southwesterly winds will occur Thursday and Friday. Light, easterly
winds will return this weekend and early next week.

&&

.CLIMATE...Based on temperatures to date and the 7 day forecast,
it looks like Tucson is headed for top 5 warmest January on
record. This would be the fourth straight month with top 5 warmest
ranking.

&&

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