TUCSON - If this ends up the swan song for the Monsoon, Mother Nature's making sure we'll go out with a bang.
According to News 4 Meteorologist Jeff Beamish, a storm system moving across the Great Basin & high pressure over northern Mexico is streaming Monsoon moisture up from the Gulf of California. This will help develop scattered thunderstorms later this afternoon & tonight.
A few storms will be capable of gusty winds and small hail.
Storm chances remain high through the weekend thanks to this "gulf surge". By Sunday night, at least a quarter-inch of rain is possible for southern Arizona, with a few spots seeing over 1".
Flash flooding may become a concern as the weekend progresses, especially if the same areas get daily rounds of storms. As always, the highest risk for flooding will be in the wildfire burn areas.
Storm chances start decreasing Monday, with a possible Monsoon shut-down by late next week.
