Temperatures will be hot with highs in the upper 90s. It will feel like it is the 100s when you factor in the higher humidity. An isolated storm could develop in the afternoon, but coverage will be very low.
Deeper Gulf moisture will increase across the area tomorrow and thru the week as an area of low pressure in the upper levels of the atmosphere pushes westward thru the Gulf of Mexico.
Rain chances will increase Friday and Saturday as a weak cold front slides into that moisture coming in from the Gulf of Mexico. I would expect scattered thunderstorms Friday and on Saturday with the front nearby.
