Climate Summary

59th Warmest on record at Indianapolis

26th Wettest on record at Indianapolis



 April started out on a warmer note for much of the area, especially in contrast to how cool temperatures were throughout most of March.  Southern portions of central Indiana made it to 70 degrees on the 1st but as a nearly stationary frontal boundary set up over the southern part of the state, high temperatures through the 3rd largely remained in the 50s and 60s. Cooler air returned with the departure of the front early on the 4th, with highs generally in the 40s and 50s over the next several days. A more substantial warmup commenced on the 9th as south-southwest winds developed on the back side of broad surface high pressure.  Many areas reached 70 degrees for the first time in 2014 on the 10th, beginning a string of four to five consecutive days with high temperatures into the middle and upper 70s. For Indianapolis, the high temperature of 74 on the 10th marked the latest first 70 degree day for a calendar year since 1984 and the 10th latest first 70 degree day on record.

The passage of a strong cold front on the 14th brought a rather abrupt end to the warmth enjoyed during the second week of the month, with winter once again returning. High temperatures on the 15th were 20 to 25 degrees below normal, with many locations remaining in the 30s with light snow showers. The coldest mornings of the month came during this stretch of cool weather, with most of central Indiana experiencing subfreezing temperatures on the 16th as lows bottomed out in the middle and upper 20s.  The return of high pressure and southerly winds kept the wintry weather short-lived, with high temperatures returning into the 70s by the 18th.  The remainder of the month was largely dominated by high pressure, with highs consistently in the 60s and 70s. A broad upper level low brought clouds and cooler weather at the end of the month as it meandered slowly east across the upper Mississippi Valley.

Additional strong thunderstorms on the 28th and 29th produced a few reports of small hail, mainly across southern and eastern portions of central Indiana.
