Temperature departures of 15-20° in Central Indiana provide the back drop for a chilly weekend. Clouds clearing this evening will allow the minimal heating from this afternoon to quickly escape due to raditional cooling. The end result will be a period of sub-freezing temperatures.
For good reason a Freeze Warning is in place overnight/predawn Sunday. I highly recommend you bring in any plants you don’t want to lose, and cover up tender vegetation outside.
Sunday highs will be warmer than Saturday, but still well below normal for April 21st.
The temperature timeline below shows sub-40° readings into the 9am hour.
For now Monday is my pick-of-the-week in the 7 day forecast… with a good dose of sun and spring-like highs in the mid 60s. Thankfully the next 60 hours will be dry, which will allow most river levels to drop below flood stage. Our next chance of rain will during the second-half of Tuesday into Wednesday morning.
Enjoy the rest of your weekend and thanks for visiting the blog – Sean Ash
