Temperatures will be above average for many this week across the Lower 48. High temps across the northern & central Plains could be 20-25 degrees above average tomorrow. By Thursday the Northeast will see temps well into the 90s. Prepare for extreme heat ahead of time: weather.gov/safety/heat

Extreme Heat Planning Timeline. Pre-Season - Start Planning before hot weather arrives: build an emergency kit, make a plan for power outages, become trained in first aid for heat-related emergencies and check that your air conditioner and fans are in working order. A few days out - If the forecast calls for extreme heat, be ready: gather food, water & medication; make a list of friends and family to check on and help prepare; know your local cooling stations or other cool locations; reschedule outdoor events. During and After - Remain vigilant and stay informed: stay in A/C and out of the sun if possible, check on friends, family, neighbors and pets, drink plenty of water, take breaks and use a buddy system if working outdoors.
