MEMPHIS, TN (WMC) - As the Beale Street Music Festival draws closer this upcoming weekend along with so many other outdoor festivities, the forecast becomes a big player in it all. It seems like the first weekend in May every year is always rain in the forecast.
Just how many times has it rained on the first weekend in May? We examined the data and in this Breakdown we are going to discuss the results. We will take a look back at the climatology to see how often rain occurs and why. These findings are based on data from the first weekend in May from 1990 to 2018.
Let’s first start by talking about “why” the first weekend in May can be so wet. April and May may not be the wettest months of the year but it rains frequently due the collision of warm and cold air as frequent fronts push though the region. April and May are months of transition from the cool to mild to the heat of the summer.
April and May also mark the peak of severe weather season.
There have only been three first weekends in May where it was dry the entire weekend. Those dry weekends were 1993, 1996 and 2015.
The rest of the first weekends in May it has rained at least one of the days including Friday. Seven of those weekends resulted in substantial rain of 1 inch or more.
Check out this chart below that breaks down the amount of rain based on the day of the week. Sunday is the day that had the least amount of rain while Friday and Saturday were equal. Friday and Saturday were also tied for days that produced rain more than 0.51 inches or greater.
