TWIN FALLS, Idaho (KMVT/KSVT) The week started cool and comfortable as we had temperatures near 80 on Monday and only in the low 70s on Tuesday. These temperatures were 5 to 10 degrees cooler than average, as we should be in the mid 80s this time of year. The cool start was thanks to a trough or dip in the jet stream over the Pacific Northwest. In fact, as most of the country baked and endured high record setting heat, the Pacific Northwest was one of the more cool and comfortable places in the United States. That is all going to changes for the Independence Day holiday and beyond.
The trough that kept our weather nice and comfortable moves out midweek and the jet stream starts to rise as the high pressure that baked the central and eastern United States moves into the western United States. This will jump temperatures up 20 plus degrees from Tuesday’s afternoon highs to Wednesday’s afternoon high temperatures. In fact, from Wednesday morning when we’re in the 40s, to the 90s in the afternoon, we will experience a 45 to 50 degree increase in daytime temperatures.
Once we get into the 90s, the heat is going to stick around through the end of the week, the weekend and the start of next week. Using common sense when it comes to the heat, like taking frequent breaks while outside, drinking plenty of fluids, checking on the elderly, and making sure our fur kids are cool and safe during these hot temperatures. You can find out how hot it is going to be on our KMVT Weather page.
