CHIEF METEOROLOGIST ERIC BRILL – EVENING UPDATE

Friday, July 23rd, 2021

An excessive heat watch has been issued for all of Gooding, Jerome and Twin Falls Counties through the end of Monday. Temperatures all throughout the weekend will likely be in the 90s for most towns and cities over the weekend and into Monday. This will likely transition over into a heat advisory for Monday. Make sure to take it slow if you plan on being outside during the heat of the day (which is usually 2 PM until 8 PM), drink plenty of water and utilize air conditioning and shade when you can!

High pressure is going to build near Southern Idaho and result in hotter temperatures for the weekend and early next week.

Expect afternoon high temps to climb to near average values this weekend and then above average values for Monday. While no daily record high temperatures are expected to be broken, it will still be a toasty three-day span! This is typically the hottest time of the year, so it isn’t like this is something completely out of nowhere. Saturday and Sunday will be on the breezier side of things, but it shouldn’t be an over-the-top breeziness, which is of course a good thing.

The weather pattern that we have seen throughout most of the week that just came to an end is expected to be back from Tuesday through the end of next week. That means that there will be more moisture in the air of Southern Idaho, which will result in more clouds and more showers. Per usual, the South Hills will have the best chance of showers during that time frame, in which Tuesday and Friday have the highest overall chances of precipitation. At this point, no severe weather or extended periods of crazy rainfall is within the forecast. Any sort of shower activity does help the drought situation within Southern Idaho, though!

Stay cool this weekend! This could end up being the hottest temps that we will see for the rest of 2021, but there is still a little bit of July and the rest of August to go!
