Spot Forecast for Menegers Dam...Tohono Oodham OEM
National Weather Service Tucson AZ
607 PM MST Wed Sep 17 2025

Forecast is based on forecast start time of 1800 MST on September 17. 

.DISCUSSION...
For the rest of the evening chances for storms and showers will continue
to diminish. There is currently one storm just to the south of Menegers but 
it is mostly staying to the south. The main concern with storms and showers 
is brief heavy rainfall leading to flash flooding. Tomorrow, there is a 30 
to 50 percent chance for storms and showers in the afternoon to evening hours. 
Again, the main concern with storms and showers is heavy rainfall leading to
flash flooding. There is a 20 to 40 percent chance for greater than 1 
inch of rainfall. By the weekend, storm chances diminish significantly
and an increasing temperature trend begins.
