Further, Β a blowing dust advisory is in effect Thursday for Pinal and eastern Pima counties from 3 p.m. to 8 p.m., the weather service says.
Thursday's heat warning means there are major risk levels for heat-related illnesses.
βItβs about five to seven degrees above normal for this time of year,β said Julia Tetrault, a National Weather Service forecaster.
While this may be the beginning of an earlier than predicted monsoon, Tatrault said, Tucsonans should still watch out for signs of heat stroke and know when to seek medical attention.
βI wouldnβt do anything strenuous until after the sun sets,β Tetrault said. βWhen we have really, really strong and high temperatures, checking in on your family and loved ones that might be more susceptible to heat (is important).β
Friday will offer some more cloud coverage, dropping high temperatures to about 103 degrees through the weekend.
Showers chances will reach into the weekend as well, with a 50% chance on Friday, followed by a 60% chance on Saturday and 50% chance on Sunday, the forecast says.
