We’re almost two weeks into spring, and so far our temperatures have really given us the guesswork over whether we need shorts or a winter coat every day. Although March has been a mild start, we have been on the cool side lately.
As April approaches, overall cold weather continues. We have what is called a weather trough in our upper-level winds. This translates to cooler and wetter weather for us. While our average high starts the month around 60 degrees, this volatile weather will keep our high near or below average for the next week and a half. The Climate Prediction Center’s official April temperature outlook places Indiana and surrounding states in an “equal probability” of temperatures approaching, below, or above average. The above trough is expected to move out of the region relatively soon. This means we should see slightly above average temperatures in the second half of the month. Our average high is about 70 degrees by the end of April.
April’s rain certainly looks into our future. Trough keeps our season active for the beginning of the month. We have almost daily chance of rain in the first seven days of April. This wetting pattern is enough for the Center for Climate Prediction to keep above average chances of rain this month. Models are mixed on the likely outcomes in the second half of the month when it comes to looking at the chance of rain.
Like any month in central Indiana, April can bring us some extreme weather. In 1997, our temperature has warmed from 18 degrees to 90. Spring storms can also bring us heavy rains and severe weather. So it’s a good time to make sure you have WRTV’s free Storm Shield app. It acts like a weather radio and sends weather alerts to your phone itself.
