Heating up for Mother’s Day weekend

PHOENIX — High pressure is building up and sending temperatures soaring.

Here in the Valley, temperatures will top out near 104º Saturday and 106° by Mother’s Day.

Breezes remain in place through Sunday with Valley gusts near 25 mph.

By Monday, we could see our hottest day of the year so far with a high of 108º in Phoenix.

An Extreme Heat Warning has been issued for Sunday and Monday for the Valley.

Heat risk will be moderate to major with our dangerous heat.

Heat Risk is the level of danger for developing heat-related illnesses like heat exhaustion or heat stroke, based on how hot it is and how your body handles the heat.

We will be under a moderate heat risk through the weekend and climb to the major risk on Monday.

Stay safe by drinking plenty of water, taking breaks in the shade or AC, and avoiding strenuous activity during the hottest part of the day.

Air Quality will also be an issued through the weekend.

An Ozone High Pollution Advisory is in place Saturday through Sunday for Maricopa County due to unhealthy air quality.

If you suffer from respiratory issues such as asthma or COPA limit time outside, carpool, ride public transportation, avoid idling in drive-thru lines, refuel your car after dark and don not use leaf blowers.

On average, it doesn’t get that hot in Phoenix until the end of May. But this year we’ve already hit 105 degrees three times in March, marking the earliest on record.

Temperatures will gradually drop next week, but the triple digits are here to stay through at least next Friday.
