PHOENIX -- Today will likely be the hottest day of the week for the Valley of the Sun. The National Weather Service has issued an Excessive Heat Warning from 10 a.m. Wednesday until 8 p.m. Thursday for near-record hot temperatures.
After a record warm morning low of 92 degrees, the Valley will warm up to about 112 degrees this afternoon under mostly sunny skies. The average high for today's date is 105 degrees and the record is 115 degrees.
Tomorrow won't bring much relief with a forecast high of 110 degrees. Drier air keeps storm chances slim today and tomorrow in the Valley, with only slim chances for isolated storms today in the high country.
Monsoon moisture is forecast to return Friday, bringing a slight chance of storms, higher humidity and lower temperatures for Friday through the weekend.
The Valley is also under an Ozone Health Watch today. Those with a sensitive respiratory system are urged to limit their time outdoors, and everyone can help out by carpooling or refueling after dark.
