An Extreme Heat Warning is in effect today across portions of Northeast Texas, Southeast Oklahoma and Southwest Arkansas. A Heat Advisory remains in effect for the remainder of the Four State Region. Heat indices could climb as high as 113 across the Warning area and upwards of 110 degrees across the Advisory area. Take precautions if being outdoors is necessary today.
Late Today into the Evening and possibly the Overnight hours, some strong thunderstorms will be possible across portions of the Four State Region. Damaging wind gusts will be the main threat...mainly across Southwest Arkansas and Northern Louisiana.
The Heat Wave shows no signs of giving way as flash drought conditions continue across the entire Four State Region. As a result, much of the region is under a Burn Ban at this time. The wildfire threat will continue.
Another very hot day is forecast across the entire Four State Region where record high temperatures will be threatened. Highs will range from near 100 to near 106 . Slight storm chances are possible very late in the day but more likely after 5 pm.
Isolated to scattered thunderstorms will be possible this evening into the overnight hours across at least the northern and eastern half of the Four State Region. Some of these storms could be strong, producing gusty winds.
With oppressive heat expected to continue through much of this week, remember these heat safety tips.
