TUCSON - Weekend storm chances on the rise courtesy of the eastern Pacific.
As Tropical Storm Ivo churns in the Pacific moisture surges our way, according to Meteorologist John Patrick. Scattered storms are in the forecast starting Saturday afternoon with periods of heavy rain the biggest concern.
Moisture really starts to increase across the region heading into Sunday which looks like our most active day for showers and storms. The heaviest rain should stay west of Tucson, however, many locations may pick up 0.50"-1.00" of rain through this weekend.
Enough moisture lingers into Monday bringing another round of scattered storms before we start to turn our storm chances back down.
