Phoenix weather: Near-record heatPosted: Updated:
PHOENIX -- It was a record warm morning in the Valley, and the day ahead promises brutal heat by the afternoon. At Sky Harbor airport, the morning low was 91 degrees, which ties the all-time warmest low recorded on this date, a record set back in 2010.
This afternoon, look for a high of about 114 in the Valley under partly sunny skies. The record high for today's date is 115 degrees.
There is a slight chance of blowing dust or an isolated thunderstorm this afternoon and evening.
Storm chances increase and afternoon temperatures finally begin to decrease later this week.
An Excessive Heat Warning is in effect for the Valley through 8 p.m. Wednesday.
Highs Wednesday are forecast near 110 degrees, with a slightly better chance of storms late in the day. Overnight lows tonight are only forecast to drop to about 93 degrees.
There is an Ozone Health Watch for the Valley today, and that could be upgraded to a High Pollution Advisory tomorrow with even higher amounts of ground-level ozone likely to form.
Carpool if you can and refuel after dark. If you have asthma or a sensitive respiratory system, you are urged to limit your time outside.
