WEST PALM BEACH, Fla. — More storms are moving in today and will stick around through the weekend, bringing much-needed relief from the recent scorching temperatures.

While it'll still be hot and humid, the extra clouds and rain should help knock the temperature down a few degrees from the extreme heat we've been experiencing.

Today, temperatures will climb to around 92 to 94 degrees under partly sunny skies, but don't let that fool you. Scattered showers and thunderstorms will start popping up late morning and become more common throughout the afternoon. Some storms could pack a punch with heavy rain, frequent lightning, and gusty winds, so keep an eye on the sky.
