Although June 1st is the first day of Meteorological Summer, the official first day is June 21st. Even though summer hasn’t officially started yet we are certainly feeling like it! It’s not just us in the Tennessee Valley experiencing the extreme heat, it is the majority of the United States. On Wednesday, multiple Heat Advisories and Extreme Heat Warnings were issued.

Heat Advisory In Effect Again Wednesday

A broad upper-level ridge over the majority of the country will continue to be dominant. This ridge will help strengthen an area of high pressure, leading to the continuation of an increase of tropical-like air. With this occurring dew points will remain on the higher end leading to oppressive humidity through the end of the week.

A weak cold front will track through the region on Friday but will bring little relief from the heat. Even though we won’t see a break in the heat, the humidity will break. The upper-level ridge will retreat westward for the weekend, thanks to the frontal passage. This will lead to temperatures hovering at 90 degrees. By Monday, the ridge begins to shift back east.

What To Expect In The Coming Weeks

As we head into the second half of June, the Climate Prediction Center is forecasting above-average temperatures. The above photos show that North Alabama has a 70 to 90 percent chance of seeing above-average temperatures between June 20-28.

The average high temperature during the 6-10 day outlook (June 20-24) is 90.2 degrees and the average high temperature during the 8-14 day outlook (June 22-28) is 90.5 degrees. These two maps show that during these time periods we have a 50 to 70 percent chance to see temperatures at or above 90 degrees.

If the upper-level ridge remains strong, we will continue to see a large influence from high pressure. This is something we will continue to monitor closely.
