The Storm Prediction Center shortly after 3 p.m. upgraded part of southern Arkansas to high risk of severe weather. Almost the entirety of Arkansas remains under a tornado watch until 9 pm. It will be extended as warranted.
Significant severe weather episode still expected this afternoon/tonight centered on Arkansas where a few strong/long-track tornadoes will be possible.
With warm, humid conditions in place, and a high wind sheer profile, Arkansas remains at risk for large hail, high thunderstorm winds, and the potential exists for strong tornadoes as a system moves closer from the plains.
Ongoing Sunday storms have already produced numerous hail reports in Oklahoma, Arkansas, and Mississippi. Some wind damage has also been reported. The greatest risk will be Sunday afternoon into Sunday evening. Additional watches, and warnings will likely be issued by the National Weather Service in Little Rock or the NWS in Jackson, Miss for Ashley and Chicot counties.
In addition to the tornado threat, the possibility of squall lines with bow echo structures increases tonight. These will be warned as severe thunderstorms. Ouachita, Bradley, and Drew counties suffered wind damage from a bow echo earlier this month, with winds in Camden exceeding 85 miles an hour. Please closely monitor the National Weather Service for additional threats today and please heed warnings issued.
