Today's Climate Data

Tropical Storm Arthur has formed in the Gulf as of this morning. The storm is expected to make landfall at some point this afternoon and quickly weaken. However, portions of central LA are likely to see flash flooding from this system as it moves northeast on Thursday.

Cannot rule out some excessive heavy rainfall overnight through Thursday across far Deep East Texas into portions of West and East Central Louisiana as the remnants of Arthur moves from Southeast Texas into Central Louisiana.

Scattered to numerous showers will be possible overnight, especially south of the I-20 Corridor as the remnants of Tropical Storm Arthur are forecast to move from Southeast Texas into Central Louisiana. Low temperatures will range mostly in the middle 70s.

Tropical downpours ahead of an approaching front will support a risk for localized flash flooding across parts of the ArkLaTex.

Showers and thunderstorms will be possible across portions of north Louisiana and Deep East Texas today with highs from the mid 80s to lower 90s.

Here are today's climate records for selected sites across the Four State Region.
