Heat related illnesses like heat exhaustion and heat stroke are possible today, especially for those who spend time outside, those without air conditioning, the young, the elderly, and those with health issues.
Reschedule strenuous activities to the early morning or wait until after dark. Wear light weight, light colored, loose clothing and drink plenty of water. Seek shade and take breaks in the air conditioning. Watch your pets and never, ever leave kids in cars, as lethal temperatures can develop in minutes.

Temperatures will drop back to the 90s after 10 p.m. and lows will fall to the mid 80s by daybreak on Tuesday. Highs on Tuesday will "only" reach 105°. Humidity is back by midweek and that fuels a few pop-up storms, delivers more clouds, and limits highs to the 90s.
