TUCSON - Will today mark the final appearance of big thunderstorm activity?

According to News 4 Meteorologist Jeff Beamish, a slow-moving low pressure center over southern California will be the trigger for scattered thunderstorms this afternoon & evening.

Unlike yesterday, we're starting off with more sunshine. That should help instigate a couple severe storms, capable of damaging winds in excess of 60 MPH, hail & flash flooding.

The best chance for storms should be from the Tucson metro, Nogales and points west. Areas east of the I-19 corridor will see storms of the isolated variety.

Drier air starts winning the atmospheric battle by tomorrow, leading to a decrease in thunderstorm activity. By the weekend, southern Arizona looks rain free.
