Another weekend is set to bring another string of potentially record-breaking high temperatures to another part of the Western United States. This time, it is the northern Rockies and the High Plains, including parts of Montana, Idaho, Wyoming and Utah, that will be under a high-pressure system known as a heat dome, according to forecasts. That will set temperatures in those states soaring through the weekend and early next week, peaking on Monday. Bozeman, Mont., could record its hottest temperature reading ever by reaching 107 degrees, according to the private forecasting service AccuWeather. This will be the fourth major heat wave to afflict parts of the West since early June, bringing dangerously hot temperatures and helping fuel the deepening drought and exploding wildfires across the region.
