PHILADELPHIA (CBS) — An unsettled, steamy pattern will keep the Delaware Valley sweltering in 90-plus degree heat through Thursday.
With humidity factored in, heat indices will skyrocket to the triple digits. Meanwhile, any showers or thunderstorms would most likely fire up during the p.m. hours, and could even be locally strong Tuesday or Thursday. An excessive heat watch is in effect for Philadelphia and surrounding counties from Thursday morning through Thursday evening.
Thursday’s stifling high of 96 degrees challenges the record of 98 last set in 1994.
Heat indices may soar to 105 degrees Wednesday and Thursday given the combination of high humidity and scorching heat.
Though scattered, any storms that ignite Tuesday could produce locally drenching downpours or damaging wind gusts.
