A cold front will enter Northwest Arkansas on Friday and sweep across the state Saturday, the National Weather Service said Thursday.
"A few severe storms could occur with the passage of the front, but widespread severe weather is not expected," Warning Coordination Meteorologist John Robinson said. He added that damaging winds will present the main weather threat.
Rainfall totals should average 1/4 inch to 3/4 inch, Robinson said, though eastern Arkansas will likely see more than an inch in places.
Sunday night temperatures should dip into the 40s, according to National Weather Service maps.
Tropical Storm Karen, which has formed in the Gulf of Mexico and sparked a hurricane watch along the Gulf Coast from Louisiana to Florida, could increase rain in the state's east, he said. While it's unlikely Karen will come north into Arkansas, tropical moisture could be drawn to the state and create rainfall totals of 2 to 3 inches in eastern Arkansas, Robinson said.
