NBC10 First Alert Weather: Excessive Heat Hits Area

Highs Monday afternoon may match the record high of 96, set back in 1957.

A First Alert is in effect until 9 p.m. Monday for excessive heat for most neighborhoods. We’re in for the hottest day of the summer season so far, and humidity will be noticeably higher too.

Afternoon readings will warm to near the record high of 96, set back in 1957. Monday’s additional humidity will make afternoon temperatures feel like they’re in the upper 90s to 100 degrees. Isolated thunderstorms are possible in the afternoon and evening, mainly from north and west of Philadelphia.

Air quality will decrease as the temperatures rise and may become unhealthy for sensitive groups. Sensitive groups include children and adults with suffering from asthma, heart disease or other lung diseases. The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors.

Be sure to wear sunscreen, drink plenty of water and avoid extended time outside, if possible.

Schools in the Camden City school district will close at 1 p.m. Monday due to the heat.

Another hot day Tuesday, near 90 degrees. However, humidity levels will drop during the day. Scattered thunderstorms are possible Tuesday afternoon, mainly across South Jersey into Delaware.
