Today looks sunny and hot, with a high near 99 and a low near 79. Heat index values may climb as high as 101, so it will feel a bit hotter than the thermometer at times.

The rain outlook is about as dry as it gets: little to no rain is expected for the rest of today through this evening, with chances staying at or below 1%.

Today’s high is about the same as yesterday, so there is not much change in the heat. Tomorrow stays sunny, with a high near 100 and a low near 79. That puts tomorrow near today’s level, with heat index values as high as 104.
