Weather forecasters say a winter storm is expected to bring freezing rain and ice accumulation in parts of Tennessee and Arkansas this week. The National Weather Service in Memphis has issued a winter storm watch for eastern Arkansas and western Tennessee for Wednesday evening and Thursday morning. The watch area includes Jonesboro, Arkansas, and Memphis, Tennessee, and its suburbs. Forecasters say freezing rain could lead to ice accumulation of up to one-half inch. The weather service says power outages and tree damage are possible and travel will likely be difficult and hazardous. Wind chills may drop into the single digits this weekend.
