COLD AND DAMP REST OF WEEK

The cool weather will hold as an upper low lingers for the next several days.  Rain chances come along with the cool, but likely to be much more scattered Thursday and Friday.  Dry time / rain free hours are likely the next 3 days but the chance of showers will grow during late morning and early afternoon hours Thursday, Friday and even Saturday as the heating of the day activates showers.

SEVERE STORM THREAT

A lull in the rain right now for most but it fills in and increases later this evening. Some storms are possible over SE and far East Indiana and they may turn severe – we are watching for the possibility that a few storms would spin and produce a tornado.  Low pressure riding north overnight bill strengthen and produce enough spin in the atmosphere that a few storms could spin up a tornado.  


Currently tornado watches are in effect over the far SE corner of the state.

A few storms could migrate north as the low pressure moves up later this evening and early tonight. Chances for a severe, tornado producing storm seem best from 4 pm to 8 PM
