A slow-moving upper level low will push east across Southern California and the Desert Southwest over the next 48 hours bringing corridors of heavy rainfall and a low risk for a couple of strong storms.
Weak instability and general messiness will limit the extent of any severe hail or wind risk, but don't be surprised to see a severe thunderstorm warning polygon or two in parts of SoCal or Arizona on Friday afternoon and evening.
Of higher likelihood is the potential for several corridors of heavy rainfall exceeding 2" to 3" by the time the upper level low pulls away from the area on Saturday morning. As such, Flood Watches have been hoisted by the National Weather Service ahead of the event.
