Forecasters say severe weather is possible in the Southern Plains, with strong winds, hail and even a few tornadoes possible.
The Storm Prediction Center said the greatest risk for bad weather is possible Tuesday in eastern Texas, eastern Oklahoma and western Arkansas. Other storms are possible elsewhere in Texas and the Ozarks.
A cold front is approaching from the west. Forecasters say potentially severe storms could develop late Tuesday afternoon in Oklahoma and Texas, then merge with another set of storms later and shift into Arkansas and far western Louisiana.
NBC 5 Meteorologist Samantha Davies said Tuesday, "A low chance of rain is in the forecast for most of the day with higher storm chances east of Dallas by late afternoon and evening. Some of these storms could be severe. Cooler weather and sunshine returns Wednesday."
Wind shear could aid tornado development, but mainly in isolated storms and before nightfall. The threat will last longest in an area from south-central to eastern to southeastern Texas.
Wind gusts could reach 60 mph and hail could be quarter-sized.
