Phoenix weather: Storm chances slimPosted: Updated:
PHOENIX -- here is still potential for monsoon storms today and tomorrow in the Valley, but chances are looking slim.
As our high-pressure ridge shifted to the east over the weekend, a southerly flow of moisture moved in from the south, leading to isolated thunderstorms in Southern and Eastern Arizona.
Today, there is a 20-percent chance of storms in the Valley, and that chance continues into tonight and tomorrow, as well. The storms could bring gusty winds, blowing dust and rain.
Afternoon highs today will top out near 106 in the Valley, and near 108 tomorrow. By Wednesday, our high-pressure ridge begins to retrograde west, which will bring temperatures up to at least 110 degrees during the afternoons, and cut off the supply of monsoon moisture from the south.
Look for hot and dry weather from Wednesday all the way through next weekend.
There is an Ozone Health Watch today for the Valley. Ozone, which is harmful to breathe, is expected to approach unhealthy levels. If you have a sensitive respiratory system, you are urged to limit your time outside today. Everyone is urged to carpool and refuel after dark.
