The National Weather Service today issued the region’s first extreme heat warning of the summer. It begins this weekend, meaning your Father’s Day is going to be extra toasty.
Maricopa residents should expect “dangerously hot conditions.” Afternoon temperatures will climb as high as 114 degrees, according to the Arizona Department of Health Services.
Meteorologists expect the region will see its first 110-degree day tomorrow, which is roughly six degrees above normal temperatures, according to NWS. The extreme heat warning is in effect tomorrow morning and through Monday night.
NWS Meteorologist Mark O’Malley cited high pressure building in the eastern part of the state for the raising temperatures in central Arizona, including Maricopa.
“High pressure during the summertime is like a large dome of warm air,” the weatherman told InMaricopa earlier this week. “When that moves over an area, that creates a lot of warming.”
Temperatures will approach but not surpass historic daily records this weekend.
Day temps will hit 110 degrees tomorrow (the record is 111 degrees), then expected to peak at 113 degrees Sunday and Monday (those records are 115 and 114 degrees, respectively).

Temperatures will cool Tuesday to 109 degrees, which is still slightly above normal.
Normal day-temperature ranges at this time of year are between 102 and 104 degrees, O’Malley said.
NWS advises Maricopa residents to limit time outdoors to avoid heat cramps and heat exhaustion.
“When possible, reschedule strenuous activities to early morning or evening,” NWS said in a statement attached to the extreme heat warning. “Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible and drink plenty of water.”
