However, the more significant threat Friday night will be isolated strong to severe storms developing overnight. A marginal risk for severe weather is in place for Friday evening. Overnight lows will drop to 73 degrees as storms move through the area.
Saturday: Scattered Storms, Still Hot
Saturday will remain hot with a high near 91 degrees and a heat index around 100 degrees. Scattered storms are expected to move into the area during the afternoon and evening hours, with some storms capable of becoming strong. A marginal risk for severe weather is also in place for Saturday evening. Overnight lows will settle near 72 degrees.
Sunday and Beyond: Gradual Cooling
Sunday will see a slight cooldown with a high near 88 degrees and a heat index in the upper 90s. Hit-or-miss storms are possible throughout the day. The overnight low will dip to 70 degrees.
Monday will continue the cooling trend with a high near 87 degrees and a heat index in the mid to upper 90s. Another chance of scattered storms is expected. The overnight low will be near 70 degrees.
What You Need to Do
During the extreme heat warning, limit outdoor activities during peak heating hours (10 a.m. to 4 p.m.). Drink plenty of water, check on elderly neighbors and relatives, and never leave children or pets in vehicles. If you must be outside, wear light-colored, loose-fitting clothing and take frequent breaks in the shade or air conditioning.
As storms develop Friday through Sunday, stay weather aware and keep your phone nearby for First Alert Weather updates. Damaging winds and heavy rain will be the primary threats with any strong storms that develop. Have a plan in place to get to shelter quickly if severe weather approaches your area.
