It is a beautiful day here in Acadiana. It all part of some colder than normal weather we’ve seen this week… normal. An interesting word but what does it mean exactly and did you know in the next few weeks our normal will be changing for good?
Climate Normals are used in meteorology to put our weather in perspective. Are we warm? Are we cold? Well, the climate normals help us determine that. These numbers are made up of historical weather data and is updated by NOAA every 10 years.
With the start of a new decade we are entering a new climate period and there are a few things we can take away from these new “normals”. Across the US we are seeing overall warmer weather with more precipitation in the central and eastern US.
Taking a closer look here in Lafayette, there is a clear warming trend but it isn’t all equal. Our normal morning lows have warmed up much more in the past 10 years with the winter, spring and fall months leading the way. Looking at our normal highs, we see a very similar trend but notice how the summer months haven’t warmed as fast though and there is a simple reason why. More rain. While our changes in normal amounts of rain are a mixed bag we have seen a large increase in our expected late spring and summer rainfall.
While our numbers today were approximated, the real climate normals will be coming out from NOAA on May 4th, this is when we will know our new normals going forward. From Lafayette, I’m Storm Track 15 Meorologist Cory Smith.
