Signs of Monsoon life in the forecast

Posted: Updated:

TUCSON - Stars, stripes, but no storms for the 4th of July. The upcoming weekend is a different story.

High pressure gradually builds back toward the state, according to 4WARN Meteorologist Jeff Beamish. This feature cranks up the heat for the Old Pueblo as highs peak in the 102-105° range this afternoon & Wednesday. Highs close in on the 110° mark for portions of Metro Tucson by Thursday.

An Excessive Heat Watch is in effect Thursday for areas west of the Old Pueblo. Highs likely reach 110°+ in central and western Pima County.

Monsoon moisture slowly returns to the Sonoran Desert to wrap the week, potentially leading to a few isolated storms. Rain chances range from 10% Thursday and Friday to 20% on Saturday.

Models indicate high pressure in a favorable position for scattered storm development starting the second half of the weekend. Metro Tucson stands a 30% chance of storms Sunday and Monday. Scattered storm chances may continue into much of next week.
