PHOENIX -- Phoenix hit a record high for today’s date. At 1:28 p.m., the temperature reached 115 degrees at Sky Harbor Airport. Some other metro-Phoenix reporting stations were even hotter, with a thermometer at Desert Botanical Garden reaching 118 degrees as of 2 p.m.
Around the state, Gila Bend was one of the hotter temps in the early afternoon with a high of 120 degrees.
The morning low at Sky Harbor Airport was 93 degrees, breaking the record for the warmest low on this date.
A strong high-pressure system is forecast to continue over the region through the end of the week. That will result in very hot temperatures through Friday.
Sufficient moisture will be in place for at least a slight chance of thunderstorms on most days through the middle of next week, but no major monsoon outbreak of storms is foreseen.
Slightly cooler afternoon temperatures are forecast for Friday as the upper-level high weakens a bit and a little more monsoon moisture spreads into the region.
A better threat for afternoon and evening convection is expected on Saturday and Sunday, as the upper-high center shifts a little further east allowing a deeper southeasterly flow to develop over the region. That will import more moisture into the desert Southwest.
Another weak shortwave embedded in this flow appears that it will move across the state on the weekend and enhance the number of thunderstorms.
Also by the weekend, temperatures will be well off the record highs we’ve seen that past couple of days with highs around metro Phoenix in the 106-110 range on Saturday and Sunday.
