Cooler and damp is a fitting description for most of central Indiana... with temperatures in the 50s and nearly 20 degrees below average. We're still eyeing the eastern-southeastern portion of the viewing area (including Columbus, Richmond, Seymour, North Vernon) for severe storm potential. This area is just outside of a Tornado Watch and within a highly sheared atmosphere that's capable of producing quick spin-ups in any low-topped showers or storms that can overcome limited instability. Be weather aware this evening.
For the moment rain has eased across the I-70 corridor, but we fully expect the wetness to ramp up again this evening with additional 1-2" possible in areas that see "training" rain develop. Flooding and Flash Flooding is a concern the next 24 hours.
Unseasonably cold air steals the headlines Thursday and Friday... when "high" temperatures will be at or below the average low (53) for this time of year. Record low maximums will be rivaled Thursday (48) and Friday (46). Anyway you slice it it's going to be chilly for mid-May standards.
The cold spell bottoms-out Saturday morning with near record lows in the mid/upper 30s and possibly areas of frost. Morning sun will give way to building cumulus clouds in the afternoon and isolated showers/sprinkles. Sunday will be warmer (though still below normal) and brighter.
A more reasonably warm patterns arrives next week and highs eventually return to the 80s. Have a great evening despite the rain.
