Phoenix weather: Another round of hot temps expectedPosted: Updated:
PHOENIX -- High pressure still in control of the southwest will bring another round of hot temperatures in the Valley of the Sun.
On Tuesday, Phoenix Sky Harbor saw its hottest temperature so far of 2014 when the mercury rose to 107. Wednesday’s forecast calls for repeat performance with an afternoon high of 107.
As high pressure shifts to the east late Wednesday and into Thursday, a southerly flow will pump in some tropical moisture from Amanda. This moisture will increase cloud cover Wednesday afternoon from south to north. This southerly flow will also keep smoke from the Slide Fire in the Flagstaff and Oak Creek Canyon area, but it may be seen as far west as Williams.
Thursday, a weak disturbance tracking into the area from the northwest will help spark isolated storms. The best chances for storms will be in the high country, but a storm cannot be ruled out in the Valley. For the most part, any storms that develop will be moisture starved, so dry lightning is a threat.
Temperatures are expected to drop to the upper 90s in the Valley Thursday afternoon, before rebounding back into triple-digit territory for Friday and into the weekend.
