A bowing line segment in Latimer and Pushmataha counties will enter northern Le Flore Co. in about 25 min and into the Fort Smith area in about an hour. Wind damage is likely and a spinup is possible. – Dave
Severe storms coming into NW AR ahead of the Adair County storm activity… small circulations are noted along the line and wind damage is possible along the tracks of these features ….this will include Fayetteville and the University of Arkansas. -Dave
8:00 PM update: Keeping a close eye on a storm near McAlester. This storm is producing winds over 40 right now but is capable of up to 60mph. There are also signs of some rotation one the north side of the storm. We are keeping an eye on it as it moves toward eastern Oklahoma and the River Valley.
7:00 PM update: Non-severe storms are moving through northwest Arkansas now. These storms will exit the area quickly.
The main line of severe storms is still hanging back in Oklahoma from Tulsa to Oklahoma City then into south-central Oklahoma. A 72 MPH gust was clocked at Vinita, OK at 6:42. The storms still look to arrive in the area after 8PM
Here is the list of counties under a TORNADO WATCH till midnight: Benton, Carroll, Crawford, Franklin, Madison, Sebastian, Washington and Adair, Cherokee, Delaware, Haskell, Latimer, Le Flore, Muskogee, Pushmataha, Sequoyah,
5:30PM update: The line of storms ahead of the cold front now stretches from just west of Tulsa, through Oklahoma City and south into north Texas. Parts of the line will start to “bow” out, meaning there is a risk of damaging winds. However, there is enough low level wind shear that could lead to brief, “spin-up” tornadoes along the leading edge of the line. Looking at 8PM for the arrival of the storms in eastern OK.
5:00 PM update: We are watching a line of storm in central Oklahoma that are tracking our way. These storms are going to be moving into a favorable severe weather environment through the evening hours. Damaging winds will be the main threat with the storms but there is enough spin in the atmosphere for us to be concerned about an isolated tornado threat. More updates coming….-Joe
