The area highlighted in orange in the southeastern portions of our coverage area is where we anticipate the highest potential for severe storms will materialize later today.
Multiple rounds of additional rainfall are expected through the latter part of the week across North and Central Texas. Widespread rainfall amounts of 2 to 6 inches can be expected with isolated amounts up to 8 inches possible across eastern Central Texas through Thursday.
