A cold front associated with a vigorous upper air disturbance will trigger widespread thunderstorms across Arkansas starting Sunday afternoon and lasting through Sunday night. A line of thunderstorms will approach Western Arkansas on Sunday afternoon and reach Central Arkansas by later in the evening.
Storms will pose mainly a hail and tornado threat across Western and Northwest Arkansas during the afternoon. As the line of storms consolidates, the main threat will become very strong damaging wind gusts. A marginal tornado threat will exist with any discrete storms that manage to develop ahead of the main line of storms. Isolated tornadoes will also be possible along the main line itself, although any of these types of tornadoes would likely be weaker and short lived.
The timing of the storms is still a little uncertain with some discrepancies among the models. Storms will approach Northwest and Western Arkansas around 1:00 pm with storms approaching Central Arkansas around 5:00 pm. The time frame for the greatest risk of severe weather for Central Arkansas will be between 5:00 pm and Midnight
There will be a high end slight risk for all of Central Arkansas, with an area of enhanced potential for significant severe weather. Significant severe means the possibility of any of the following: EF2 or greater tornado, wind gusts exceeding 74 MPH, or hail size 2” diameter or greater. Wind appears to the primary concern.
An upgrade to moderate risk for parts of Central Arkansas is possible in subsequent updates.
