LITTLE ROCK, Ark.- 5 PM Update– A system is moving across the Central Plains today and will continue its journey overnight. Out ahead of this system, showers and thunderstorms have developed as forecast and will continue to spread west to east across Arkansas this evening and into the overnight hours. A few of those storms could become strong to severe.
While the greatest severe weather risk tonight will reside outside of Arkansas to the west and south, we cannot rule out that some of those stronger storms could still be at or reach severe status near the state line. This is why the slight risk was expanded to include far west and southern Arkansas.
THREATS: The main concern will be brief but strong wind gusts that could reach 60 MPH. Hail up to 1″ in diameter cannot be ruled. The tornado threat is VERY low for tonight. The only area where a brief tornado may occur would be across FAR southern Arkansas.
ADDITIONAL CONCERN: Heavy rainfall may also become an issue where thunderstorms train over the same area causing isolated flash flooding. The southern 1/2 of the state would be where we watch this as 1 to 2 inches of rain is forecast for all the activity that is expected tonight.
TIMING: Showers and storms will continue to spread slowly west to east across Arkansas this evening. This main wave should begin to push out of Arkansas around midnight.
There is some data suggesting that past midnight, a final wave of storms should develop over Oklahoma and move east into Arkansas. While this scenario looks possible, its ability to remain intact as it moves over Arkansas is questionable. This evening, much of the state will have already been worked over from storms. This will reduce the atmosphere’s ability to support additional thunderstorm activity.
