– Freak July cold front brings snow to Northern Rockies (Ice Age Now, July 28, 2015):
Shatters daytime temperature records across Idaho.
The combination of moisture and cold air was expected to settle over Idaho, Montana and Wyoming through Tuesday in a pattern rarely seen in those states before late August or September, said forecasters with the National Weather Service.
More than an inch of snow was reported on Monday in the mountains of western Montana, central Idaho, and at the Jackson Hole, Wyoming ski area.
With a possible freeze in the forecast, farmers in Salmon, Idaho, scrambled to cover their crops.
Peak daytime temperatures set cold records in much of Idaho on Monday, with highs running 10 degrees colder than usual, said Travis Wyatt, a Weather Service meteorologist in Pocatello.
In Idaho Falls the mercury climbed to just 68 F on Monday, six degrees below the previous record low high for the date set in 1993. In Challis, Idaho, the daytime temperature rose to only 66 F, shattering the previous record of 72 set on July 27, 1940, some 75 years ago.
“It’s very rare for a cold front to move through in July. It has happened before, but it’s anomalous,” Wyatt said.
