I'm looking at my first 100F+ commute this PM - forecast to be 109F.

While 109F is relatively cool for mid-summer, it has come suddenly - all previous PM commutes this year have been 90F and under.

"A STRONG AREA OF HIGH PRESSURE ALOFT WILL MAKE FOR UNSEASONABLY HOT
TEMPERATURES THE FIRST COUPLE OF DAYS THIS WEEK...WITH AFTERNOON HIGH
TEMPERATURES FROM 15 TO 20 DEGREES ABOVE NORMAL. IN FACT...IF THE
OFFICIAL HIGH TEMPERATURE AT PHOENIX SKY HARBOR REACHES THE PREDICTED
HIGH OF 110 DEGREES TODAY /MONDAY/...IT WILL MARK THE FIRST TIME IN
RECORDED HISTORY THAT THE INITIAL 100 DEGREE HIGH TEMPERATURE OF THE
SEASON WAS IMMEDIATELY FOLLOWED THE NEXT DAY BY THE FIRST 110 DEGREE
READING."
