June 1st begins the start of meteorological Summer for the northern hemisphere. To explore what to expect this upcoming summer for Central Missouri, we must first look back to the past expanding back to 1970. From 1970 through 2021, research has shown that the average temperatures from June through the end of August show a warming increase of 1.7 degrees.
This increase in the average temperature trends ties into what Missouri is expected to see this upcoming summer when taking a look at the three-month outlook.
Trends point towards the majority of Central Missouri seeing a 40-55% chance of above average temperatures.
When peaking into the precipitation outlook, the northwestern half of Missouri looks to expect conditions to be slightly dryer than average, while the southeastern segment can expect normal amounts of rainfall.
When comparing Central Missouri to the rest of the United States, research shows only a slight increase in temperatures while the majority of the west coast has seen sharp increases of 3 degrees on average per summer season.
The reasoning behind forecasted high temperatures this summer is due to a La Nina pattern currently in effect. The current La Nina pattern forces the Polar Jet Stream to rise north funneling warmer air across the majority of the United States.
