PHOENIX -- Monday's forecast of significant rain for the Valley has been, so far, pretty much a bust. The upper level disturbance that looked like it would enhance our monsoon thunderstorms Tuesday pretty much was sheared apart. Now we’re looking at a more typical monsoon forecast for the rest of Tuesday, a chance for scattered evening storms.
An area of low pressure passing to the north of Arizona is drawing enough moisture into the state for an active day and, in the deserts, we’ve gotten the daytime heating and also helps to trigger storms. Northern Arizona received some significant rain Tuesday and may see more overnight.
As the low pressure system passes to the north and east away from Arizona on Wednesday, we’ll see a drying trend that will also result in much warmer temperatures. In fact, by the weekend, we may see some highs around metro Phoenix in the 110-degree range. It’s also looking very dry through the weekend.
Some of the rainfall totals in northern Arizona include ½” at Concho, 1/3” at Prescott and ¼” of rain at Clarkdale.
