The heat won’t break anytime soon

Although June 1 is the first day of meteorological summer, the official first day is June 21. Even though summer hasn’t officially started yet, we definitely want it! It’s not just us in the Tennessee Valley experiencing extreme heat, it’s the majority of the United States. On Tuesday, several heat advisories and extreme heat warnings were issued. Chicago, which was under an extreme heat warning, had a high temperature of 100 degrees.

Heat advisory in effect again Wednesday

The heat won't break anytime soon

A broad upper level ridge over the majority of the country will continue to be dominant. This ridge will help reinforce an area of ​​high pressure, leading to a continuation of rising tropical-like air. With this, dew points will remain at the high end, bringing oppressive humidity through the end of the week.

A weak cold front will cross 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. With some drier air filtering through, even with the lingering heat this weekend, it will be a bit more comfortable.

What to expect in the coming weeks

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

The average high temperature during the 6-10 day forecast (June 20-24) is 90.2 degrees and the average high temperature during the 8-14 day forecast (June 22-28) is 90.5 degrees. These two maps show that during these times we have a 50-70% chance of seeing temperatures at or above 90 degrees.

At Muscle Shoals, the rain deficit is 1.45 inches with only 0.85 inches so far for the month of June. Looking at the latest Drought Monitor, we continue to see isolated areas of abnormally dry conditions. The next Drought Monitor update will be released on Thursday, June 16.

As we head into the second half of June, the Climate Prediction Center predicts below average rainfall. The photos above show that northern Alabama has a 30-60% chance of seeing below average rainfall between June 20-28.

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