Boise is going to get unseasonably warm, then unseasonably cold weather within two days, according to the National Weather Service.
Treasure Valley residents will get warm weather Monday with highs in the mid-70s to low-80s. Then a cold front will bring a dramatic cool-down to the valley, bringing temperatures down to the low-40s, according to Les Colin, meteorologist for the National Weather Service's Boise office.
The strong cold front will bring rain, snow and wind with it Tuesday, Colin said.
The winds will be about 25 mph in Boise with gusts of 40 mph. East of Boise will get even stronger winds, though. Mountain Home, Twin Falls and Jerome will likely get a wind advisory Tuesday. Residents there could see sustained winds of 30 mph with gusts of 50 mph, Colin said.
Never miss a local story.
Snow and rain will fall in the Treasure Valley Tuesday, but it likely won't accumulate. Bogus Basin is expected to get 6 inches of snow, Colin said.
The erratic weather is hitting two extremes for April, but it's normal to have fluctuating temperatures, he said.
"This is April. This is what it's supposed to do for a while," Colin said.
