 Exercise heat precautions once again, water, shade, sunscreen, and limit time outside during the afternoon. Tuesday is a repeat, and both days will have isolated storm chances about 20% or less. So if you do get one of those thunderstorms, it won't last too long, but it will bring some heat relief temporarily. Better rain chances return Thursday and Friday as moisture from Beryl moves in toward the mid-Atlantic. That will lower the temperatures as well, down to 88 degrees.
