Much lower coverage of thunderstorms is expected across the forecast area today compared to that of yesterday. Chances for isolated lower desert storms remain, with the best chances during the mid to late afternoon. Isolated shower & storm activity will likely linger into the evening and taper off with time. All the typical hazards remain on the table: strong, gusty outflow winds, areas of blowing dust/sand, and localized heavy rainfall.
Early next week, subtropical high pressure will migrate from the Southeast US back to the Desert Southwest and build over the region. This will result in hotter temperatures with little overnight relief in the urban lower elevations. An Extreme Heat Watch has been issued for the Phoenix Metro Area and will be in effect Monday through Wednesday next week.
