PHOENIX -- After a very active thunderstorm day around the state on Monday, Tuesday has featured fewer thunderstorms statewide. Most of the storms were in northern Arizona but we also had a few isolated thunderstorms in the northeast and southeast portions of the Valley. For the rest of Tuesday night, there’s still a chance some more of those isolated storms could form. Overnight lows will be in the 80s.
Wednesday will feature an upswing in monsoon activity around the state. And right now, Thursday is looking like a very active rain day as we tap into moisture from Mexico, much of which is the remains of Tropical Storm Fernand. We also expect a weather disturbance in the upper atmosphere to enhance thunderstorm growth late week.
Besides the increasing chances for rain, we’re also going to see rather cool temperatures for this time of year as we head toward the Labor Day holiday weekend. We’re looking at highs in the 90s. That’s below average for this time of year.
