Some thunderstorms will probably develop this afternoon and evening over the southeastern half of Arkansas. An isolated severe storm or two cannot be ruled out.
However, John Robinson, Warning Coordination Meteorologist for the National Weather Service at Little Rock, says the big event will be a line of thunderstorms that takes shape well to the west of Arkansas today. This line should enter western Arkansas after midnight tonight and progress quickly eastward across the state during the daytime on Monday. I expect that we will see quite a few severe thunderstorm warnings issued. Damaging winds will be the main threat, by far. It’s possible that we could see some thunderstorm winds exceeding 70 mph, especially in the eastern half of Arkansas on Monday afternoon. Isolated tornadoes could occur as well. These storms should exit Arkansas before dark. However, it’s not out of the question that a few hail-producing storms could redevelop in western Arkansas during the afternoon and move eastward during the evening.
Rainfall amounts will average 3/4 inch to 1 1/2 inches, with local totals of at least 2 to 3 inches. Flash Flood Watches have already been issued for seven counties in northwest Arkansas, and the Watches may be extended to additional counties in forecasts issued later today.
