Southern Idaho Weather Forecast
CHIEF METEOROLOGIST ERIC BRILL – EVENING UPDATE
Thursday, July 30, 2020
A heat advisory has been issued for all of Cassia, Minidoka and Lincoln Counties, as well as Southeastern Blaine County for Friday. What it comes down to is that temperatures are going to have the ability to be in the upper 90s to lower triple digits on both of these given days. This looks to be the case for a lot of the Magic Valley as well. Try to avoid being outside during the heat of the day (which is approximately 2 PM until 8 PM), make sure to take frequent breaks, drink plenty of water, and check up on the kids and elderly. While this heat isn’t the most uncommon thing for Southern Idaho to see, it doesn’t mean that it won’t be hot!
Hot weather conditions are expected through the beginning of next week before a cold front is expected to move through Southern Idaho.
There really aren’t many variances of the forecast over the next handful of days, as temperatures will be 5-10° above average for both highs and lows. Mostly sunny to sunny skies are expected more often than not, with the exception being on Saturday. That is when a very weak cold front is going to move through Southern Idaho, and knock temperatures down a couple of degrees. The hottest day during this span looks to be the last day of July, which is Friday.
For the beginning of next week, breezy weather will return to Southern Idaho for both Monday and Tuesday. The combination of dry weather, low humidity values, hot temperatures and breezy conditions will likely enhance the fire danger all around the area. Those are going to be days to keep an eye on when it comes to red flag/fire weather warning. One positive thing is that there doesn’t appear to be any lightning in the forecast for that given day, so that should help the cause slightly.
The breezy weather for Monday and Tuesday will be thanks to a cold front that will move through the area. This is going to knock temperatures down to near average values for Tuesday and Wednesday. That means that the Wood River Valley will top-off in the middle 80s for highs, while the Magic Valley and Mini-Cassia Region can expect some upper 80s. Sunshine filled skies will continue during this time period, and even into Thursday.
Keep cool, and drink plenty of water over the next few days! Southern Idaho is going to be HOT!! Make sure to wear loose clothing, keep an eye on the kids/elderly/pets, and take it slow out there! Taking frequent breaks, and avoiding being outdoors during the hottest portion of the day (approximately 2 PM to 8 PM) is also a great idea!
