Hot and dry weather can be expected again today, though a change in the weather is expected late Friday into Saturday morning as a cold front moves into the region. Showers and storms will be possible ahead of this front, and unsettled weather could continue into the weekend.

A few strong to severe storms will be possible Friday afternoon and evening, with locally gusty winds, heavy rainfall, and lightning being the main threats.

Additional rounds of thunderstorms through Wednesday will produce 2 to 4 inches of total rainfall, with locally higher amounts possible. Localized flooding is likely where heavier and/or repeated rainfall occurs.
