LITTLE ROCK, Ark. — We managed to enjoy a short period of comfortable weather conditions. After a week of already extremely hot temperatures across the mid-South, we’re expecting another wave of intense heat to hit later this week.
Tuesday marks the first day of summer, and it will sure feel like it as temperatures surge back into the upper 90s, and likely into the 100s as early as Tuesday.
So far, the hottest temperature we’ve reached Little Rock this year was 98° on June 17. To be considered a heat wave, temperatures need to exceed 95° for at least three days in a row.
We’ve been stuck in this pattern thanks to a ridge of high pressure that has been meandering over the region, putting us under a heat dome. This ridge blocks most organized storm systems from entering, which is why we have gone so long seeing little to no rain.
When we go this long without seeing substantial rain, the ground dries out. This allows for temperatures to heat up faster, resulting in higher temperatures.
Unlike last week, the humidity won’t be as high, with dew points in the 60s and 70s. Once the heat index reaches 105° heat advisories are issued by the National Weather Service. This will be a good possibility for parts or all of Arkansas this week.
Although not unheard of, it is a bit early in the season to be dealing with these high temperatures. On average our first 100° day is not until mid-July.
A look at our weather history shows the lack of 100 degree temperatures we have seen over the years. The first and only time in 2021 we saw 100° in Little Rock was back on September 1st. Prior to that, we hadn’t observed 100° since July 15, 2018.
Be prepared for uncomfortable sleeping weather and dangerous heat during the afternoon. Stay hydrated and take frequent breaks.
Check on your neighbors and don’t forget to keep the pets cool and hydrated.
