As of this afternoon, the air temperature stands at 88 degrees Fahrenheit, though it feels like 93 degrees due to the humidity. The relative humidity is 55 percent, with a dew point of 70 degrees Fahrenheit, creating a muggy atmosphere.

Winds are blowing from the south at 16 miles per hour, with gusts reaching 24 miles per hour. The sky remains cloudy, and residents should be prepared for isolated rain showers before 4 p.m., followed by scattered showers and thunderstorms. The high temperature is expected to reach near 93 degrees, with heat index values potentially climbing to 99 degrees.

There is a 35 percent chance of precipitation, with new rainfall amounts between a quarter and half of an inch possible.

Safety Reminders

Given the active flood watch and the potential for one to two inches of rainfall, residents should avoid driving through standing water and stay alert for flash flood warnings. The high humidity and heat index values today warrant staying hydrated and limiting midday exertion.
