Southern Idaho Weather Forecast
CHIEF METEOROLOGIST ERIC BRILL – EVENING UPDATE
Wednesday, August 05, 2020
There is another red flag warning in place for the majority of the Mini-Cassia Region and Eastern Idaho for Thursday. The possibility for thunderstorm and lightning development will be around for Thursday afternoon and evening, and the combination of that, breezy conditions, dry weather over the past few weeks and low humidity values means that fires could start and spread quickly due to Mother Nature. With that already working against us, please do your best to avoid starting fires on Thursday!
Temperatures that won’t be as warm as Wednesday afternoon are expected to return to Southern Idaho as the last two days of the week develop.
A cold front moved through the region, which is the culprit for the cooler temperatures. By cooler, I don’t exactly expect highs in the 70s, but middle to upper 80s are expected area wide for Thursday, while lower 80s will be back in play for Friday. Speaking of Friday, that will likely have the ‘coolest’ high temperatures over the next week. Like Wednesday, showers and storms could develop during the afternoon and evening hours, and that would prevent temperatures from reaching the warmest possible numbers that they could. Thursday does have a little bit better chance of rain than that of Friday. Breezy weather is also in the forecast for Thursday and Friday, as a lot of Southern Idaho will see sustained winds in the 10-20 mph range for most of the afternoon and evening. As far as the weekend goes, some great weather is expected! Mostly sunny to sunny skies are within the forecast, which also means that it will be dry. Temperatures within the Magic Valley and Mini-Cassia Region will reach the middle to upper 80s, while the Wood River Valley will top-off in the lower to middle 80s. A lingering breeze will be around as well, but I anticipate that the weather will be too nice to really notice it!!
Early next week does start off slight warmer under mostly sunny skies. Both high and low temperatures are expected to be within a few degrees of average, and that pesky lingering breeze is expected to be in place.
Slight chances of showers and storms will be back in the forecast for Tuesday and Wednesday, but there is some disagreement within that. Some of the computer data that I’ve seen indicates that areas to the north of Southern Idaho have a better chance of those showers, while others indicate that our region could get a little bit wet. I’m leaning towards the drier side of things right now, but won’t completely rule out the possibility for showers next week. Temperatures during that time will continue to be near average, so there really aren’t any BIG temperature swings ahead over the next seven days.
Those of you that enjoy the hot temperatures need to take advantage of what we have! While the next seven days won’t exactly be anything most people would call chilly, they won’t be as warm as the previous seven days. As a whole, some nice weather is on tap more often than not over the next week!
