Severe weather is unlikely, but a few strong storms with gusty winds, localized heavy rainfall, and frequent lightning may occur. Typical hot summer weather is otherwise expected with highs in the mid 90s to 100°.

Next week will bring typical July weather, with daytime highs ranging from the mid-90s to around 100 and overnight lows in the mid 70s to low 80s.
