"An approaching cold front is likely to bring a line of thunderstorms, along with the threat of some severe weather, tonight and Thursday.
The thunderstorm threat will probably hold off in the northwest corner of Arkansas until this evening. Then, from late evening on into the overnight hours, chances for severe weather should diminish somewhat while spreading across approximately the western third of the state.
Initially, the weather system is likely to produce some tornadoes, but this will be in areas to the northwest of Arkansas. The tornado threat should diminish somewhat by the time the storms reach Arkansas, but an isolated tornado cannot be ruled out. Overall, however, damaging winds should be the main severe weather threat with a lesser chance of large hail.
On Thursday, as the cold front makes its way across the rest of Arkansas, damaging winds should be the main severe weather threat, though there could be a few instances of hail. An isolated tornado can't be ruled out entirely, but chances are pretty small.
Instability will not be all that great as the storms move across Arkansas, so this will limit the amount of severe weather that might otherwise occur. On the other hand, winds aloft will be fairly strong, so I do think we will see at least a few severe thunderstorm warnings issued.
Rainfall amounts should average 1/4 to 3/4 inch, but there will be some local amounts to at least an inch.
I will issue an update around 3:30 PM this afternoon, but I suspect there will not be a lot of changes to the above thinking.
