PHOENIX — After a stormy night in the Valley, we cooled down for Sunday but the heat returns for the start of the week.
The heat dome over the west is strengthening for the start of the week which will dry out our monsoon moisture for a few days and send temperatures soaring 10-15 degrees above normal around the state.
An Excessive Heat Warning for parts of Maricopa and Gila counties and along the lower Colorado River Valley will be in place Monday and Tuesday.
Temperatures are expected to range between 110-115 degrees in our lower deserts
That means both days will be ABC15 Weather Action Days now is the time to prepare you and your family for the dangerous heat.
Consider changing outdoor plans, limiting outdoor activities between the hours of 10 a.m. and 6 p.m., stay hydrated with plenty of water and electrolytes, seek A/C, use sunblock and never leave pets or kids inside hot cars.
Risk for heat related illnesses will be elevated to Major for Monday and Tuesday meaning everyone is at risk for heat exhaustion or heat stroke.
Phoenix is in the middle of the longest stretch of triple-digit days ever recorded!
As of Sunday, we've had 84 days in a row at 100 degrees or hotter. The previous record was 76 consecutive triple-digit days set in August of 1993.
As temperatures heat up, we're also getting close to the all time record number of days with lows in the 90s.
Saturday morning not only tied the record for overnight warm low at 93 degrees but it also put us at 35 days with overnight lows in the 90s. The record is 35 days, set just last year. We could break that record as we head into Monday.
