A similar pattern in thunderstorm development is anticipated this afternoon, with storms initially forming in the typically favored Northern and Eastern AZ high terrain as well as portions of Southeast AZ. Storm chances then spread to the lower deserts of South-Central AZ (including the Phoenix Metro) by the evening and linger into the overnight period. Thunderstorm hazards will be similar to that of Sunday/Sunday night, with strong, gusty outflow winds that could bring dense dust with them, locally heavy rainfall, and frequent lightning. There is once again a low chance for a few strong to severe, isolated afternoon T-storms to form in Southeast CA (Imperial County).
Lower deserts highs will top out at 110 degrees today, resulting in areas of Major HeatRisk. Temperatures gradually cool through the upcoming week. Deeper moisture will lead to better chances for more widespread shower and thunderstorm activity through the middle of the week with Monday and Wednesday into Thursday looking like the most active periods at this time.
