The stretch of dangerous heat tied the record Monday and is set to reach 19 days on Tuesday. > Nighttime has offered little relief from the brutal temperatures. Phoenix's low of 95 F (35 C) on Monday was its highest overnight low ever, smashing the previous record of 93 F (33.8 C) set in 2009. It was the eighth straight day of temperatures not falling below 90 F (32.2 C), another record.
