Severe Weather Outlook – Sunday (Based on Latest SPC Forecast)
The NOAA Storm Prediction Center (SPC) has issued an Enhanced Risk (Level 3 of 5) for severe thunderstorms late Sunday afternoon through Sunday night across parts of the Mid-South, Lower Mississippi Valley, and Lower Ohio Valley, with storms moving east toward the Appalachians overnight. 
This means organized severe thunderstorms are likely, with damaging winds being the primary concern.
Main Threats
Storms developing later today could produce:
• 💨 Damaging straight-line winds, potentially exceeding 60 mph
• 🌪️ A few tornadoes, especially within stronger storm cells
• 🧊 Large hail in isolated storms
• ⛈️ A developing squall line capable of widespread severe wind gusts
The strongest winds may occur within a fast-moving line of storms that forms along a cold front pushing east across the Mississippi Valley during the afternoon and evening hours. 
Meteorological Setup
A deepening low-pressure system and strong upper-level trough are moving across the central United States today. As this system strengthens, strong winds throughout the atmosphere and a developing cold front will help thunderstorms organize into a large squall line capable of producing widespread damaging winds. 
Moist air returning from the Gulf of Mexico will provide enough instability for storms, though limited moisture may keep the overall tornado threat somewhat lower than in stronger outbreaks. 
Timing
• Afternoon: Storms begin developing along the cold front.
• Evening: Severe storms intensify and form a squall line.
• Overnight: Storms push east toward the Appalachians and Southeast.
Key Takeaway
Residents across the risk areas should remain weather aware Sunday evening and overnight, especially since storms may arrive after dark. Damaging winds appear to be the primary hazard, but isolated tornadoes are possible within stronger storms.
