For these reasons, the Storm Prediction Center has issued a somewhat rare "Moderate Risk" area that encompasses the tri-state for tomorrow. According to the NWS, only about 10 times a year are moderate risk areas issued for Day 2. The risk area is shown in the map below. The second map shows the probability of severe weather within 25 miles of any one point, with the hatched area (over west TN, N MS, and AR) indicating a 10% chance or greater of "significant severe" weather within 25 miles of any point. In other words, it appears our chance of seeing severe weather in the metro is about 50/50 (which is pretty high).
Thunderstorms are possible overnight tonight and early tomorrow as the warm front moves through the region from south to north, though these storms will stay below severe limits. A lull in the action is expected tomorrow morning and early afternoon before storms begin to fire to our west by mid-afternoon. I expect the greatest threat of severe weather, including tornadoes, to be between 5-10pm in the immediate area, earlier in east AR and later to our east. Very heavy rain, damaging straight-line wind, large hail, and frequent lightning are all possible to probable as well.
