Temperatures are expected to hit the low to mid 90s today, with humidity driving the heat index into the high 90s.
The heat, the National Weather Service warns, has the potential of increasing the risk for heat-related illness.
The NWS recommends limiting exposure to heat outside if possible and drinking plenty of fluids.
The weather forecast for tomorrow is scattered thunderstorms in the morning, becoming more widespread with possible severe storms in the afternoon.
The storms, which could extend into the night, may produce large hail and strong winds.
