 Another steamy day today with the exception of the far down east coast where high temperatures could stay in the 70s. Elsewhere, though, 80s and 90s with some heat index readings getting up to about 100 degrees today. Tonight, we'll have a chance of showers, maybe a thunderstorm, some of which could produce some heavy rain. Overnight lows in the 60s. Then tomorrow, one more hazy, hot, humid day. High temperatures back into the 80s and 90s with showers and thunderstorms late.
