There is a marginal risk of severe storms on Wednesday for a portion of central and all of southern Indiana.  A shortwave trough will move through the area on today and bring showers and thunderstorms to the area. While dynamics overall are not overly impressive, it should be sufficient enough for isolated storms to reach severe limits by this afternoon, with damaging winds as the primary threat.Slide15There is a marginal risk of severe storms on Thursday for southeast Indiana as the shortwave trough progresses eastward.  Showers and thunderstorms will likely be ongoing at the start of the period, but should clear out by the mid to late morning hours.  This should allow for some clearing and possible reloading of the atmosphere.  While shear and lapse rates will be weak, instability should be on the moderate side and a stronger low to mid level flow should allow for new storm development during the afternoon hours, some of which could reach severe limits, with damaging winds as the primary threat.  We will need to monitor this area closely for possible upgrades in future outlooks.  Otherwise, severe weather is not expected Friday for Indiana.
