Fairly strong tornado potential today through Thursday before a much quieter pattern takes over this weekend into early next week.
NOTE: If we leave for Chasecation 2017 at the end of this week, this will be the last forecast until we get back. If we don’t leave, I will probably keep forecasting until we do leave.
