Monday’s Tucson Forecast: A brief glimmer of Monsoon hope

From excessive heat to isolated storms.

Enough Monsoon moisture is in play for a 10% chance of metro storms today. Cochise, Graham and Greenlee Counties appear to be the favored areas for isolated storm development between 1-8 PM. Most places stay thunder free to start the week.

For the 26th time this year, Tucson peaks in the 100s. This afternoon’s forecast high of 107° is 5° above average for late June.

Overnight lows bottom out in the low 80s in the Old Pueblo. Storms should quickly fade away after sunset.

High pressure parks west of the state for much of the week. This ensures dry air over the Sonoran Desert & keeps highs in the 104-107° range. Ample sunshine prevails in Tucson tomorrow through the upcoming weekend.

Long range models indicate high pressure drifting toward the Four Corners for 4th of July week. While it remains unclear if storm chances increase, this pattern is favorable for Monsoon moisture to enter the state.
