Strong to severe thunderstorms with gusty winds are possible in the afternoon and early evening, the outlook said. Heavy rain is possible and could cause flooding in low areas or those with poor drainage.
Lambert said the thunderstorms will be the result of conditions, not because of larger storms moving through the area. Watch out for lightning and high winds, he said. If you are outside, get inside. If you are inside, go to the basement or the lowest level of your house.
A high heat index creates problems for folks without access to air conditioning. LifePath Christian Ministries is trying to help those in York County by providing cooling stations.
