Area Forecast Discussion
National Weather Service Tucson AZ
122 PM MST Thu Nov 21 2024

.SYNOPSIS...
High pressure will bring warmer than normal temperatures to the
area through the weekend then temperatures gradually cool next
week leading up to Thanksgiving Day.

&&

.DISCUSSION...
A high amplitude ridge is centered over the Intermountain West
today, with deep troughs impacting both the West and East Coasts.
Weather is quiet under the ridge, with just a broad area of high
clouds moving overhead. We are on track to reach the 70s to lower
80s across the forecast area, warmest around Tucson and westward.
These high temperatures are on the order of 5 to 10 degrees warmer
than normal. Similarly warm temperatures (if not slightly warmer)
are expected Friday and Saturday under the influence of strong
high pressure.

A slow but steady cooling trend begins on Sunday and continues
next week as the atmospheric river impacting the West Coast
finally moves inland, pushing the upper ridge eastward. This may
also bring occasional breezy conditions to the forecast area. By
the middle of next week (Wednesday`ish), the upper trough clips
our region. The best chances of precipitation should stay to our
north, but we will continue to monitor weather trends as changes
could impact holiday travel.

northeast portions of the forecast area Tuesday into Thursday of

through Saturday, lowering back to 3-5 degrees above normal early
next week. Min RH values will be 8-15 percent in the valleys and
10- 20 percent in the mountains through the weekend. Min RH values
