Area Forecast Discussion National Weather Service Tucson AZ 800 AM MST Thu Jul 17 2025
SYNOPSIS
Low-grade monsoon pattern through the weekend with high temperatures around normal.
UPDATE
Mostly clear skies this morning with some developing clouds along the International Border and along the Sky Islands.
The passing upper level low, currently located off the northern coast of Baja, will draw moisture out of our area pushing it into northern Arizona keeping PWATs between 0.9 to 1.2 inches this afternoon here in southern Arizona. Today, very slight chance (15 to 30 percent) for isolated showers and thunderstorms. The greatest chance for storms and showers will in the White Mountains. High temperatures will be around 95 to 100 degrees, 4 to 9 degrees warmer than yesterday.
PREV DISCUSSION
/issued 305 AM MST Thu Jul 17 2025/
DISCUSSION
Infrared satellite imagery this morning showed considerable cloud cover west of Tucson into SW AZ associated an MCV. Water vapor imagery showed upper low near the Baja Spur lifting slowly to the north. PWAT values this morning, per GOES-19, ranged from 0.90" to 1.40" with the drier air over Santa Cruz county. At the surface dewpoints were in the upper 50s to upper 60s.
Today: The Baja Spur upper low will continue to lift slowly north with southerly flow over the area. Low grade monsoon day with mostly isolated storms as surface dewpoints mix down into lower to mid 50s. Better chances of storms in the Whites. Thanks to more sunshine, highs will run 4 to 9 degrees warmer than yesterday.
Friday: Flow aloft remains southerly with the Baja upper low near San Diego by early evening. Once again looking at a low-grade monsoon day with surface dewpoints mixing down into the upper 40s to mid 50s. Highs around 2 to 4 degrees warmer than today. There is the potential for a few storms moving into the area during the overnight hours thanks to outflows from Sonora MX. These outflows will bring an increase in low-level moisture.
This weekend: Slight uptick in chances of afternoon/evening storms as we work on recycled moisture. Highs right around normal.
Next week: Chance of afternoon/evening storms each day with no day sticking out to be more active than the other. Highs right around normal.
