Area Forecast Discussion
National Weather Service Tucson AZ
300 AM MST Sun Jul 6 2025

.SYNOPSIS...Expect scattered storm coverage today focused on
locales generally south and southwest of Tucson. With deep
moisture in place across Southeast Arizona, the main hazard from
the storms today will be their capability to produce heavy rain.
Otherwise, temperatures will warm back up to above normal levels
this weekend with the potential for extreme heat to return to
Southeast Arizona by the middle of next week.

&&

.DISCUSSION...The sky was clear this morning across most of SE
Arizona. The exception was scattered clouds NE of Safford. GOES-19
PWAT imagery showed values ranging from 1" near the AZ/NM border
to 1.40" over western Pima county.

The main theme this week will be an expanding strong ridge of high
pressure aloft over the state resulting in very hot, near record
high temperatures mid-week and a low grade monsoon pattern.

For today, latest CAMs show scattered showers/storms this
afternoon and early evening S and SE of Tucson. Brief heavy rain
and gusts up to 45 mph main threats with the storms.

As mentioned above, its going to get hot again with Wednesday
being the hottest day with near record highs. For Tucson the
record high for Wednesday (9th) is 111 degrees with latest NBM
probabilities having a 62% chance for 110, 35% chance for 111 and
11% chance for 112. With all that said, an Excessive Heat Watch
has been hoisted for the lower elevations of Pima, Pinal and
Graham counties.

&&

.FIRE WEATHER...A decrease in thunderstorm activity is expected
today into early this week as the area transitions into a low
grade monsoon pattern. An eventual uptick in monsoon activity is
possible the middle of next week but will be dependent on how
quick the high pressure aloft shifts north. Temperatures heating
up this week with hottest temperatures mid-week. Winds generally
light and under 15 mph with the exception of gusty and erratic
winds up to 35-45 mph near any thunderstorms.
