The Treasure Valley saw a nice break of sunshine after over night snow hit the gem state. The next wave will begin again on Thursday with morning overcast followed by increasing snow throughout the day.
A cold front passed through yesterday triggering thunderstorms, strong wind gusts (50-70mph wind gusts) and whiteout conditions for some areas. Mountain Home AFB measured a wind gust of 67mph, Boise's top wind gust hit 49mph and Twin Falls experienced a 59mph wind gust. Highway 20 is closed in both directions (as of 4:15 AM) from Dixie to Fairfield due to blizzard conditions.
A second cold front made its way across the Treasure Valley with heavy snow showers impacting the Wednesday morning commute. The National Weather Service in Boise measured nearly 3 inches of snowfall in less than 3 hours! Snow will came to an end by 9:00 AM in the Treasure Valley, with snow continuing through lunchtime in the Magic Valley.
Windy conditions will persist throughout the day, with gusts to 35mpg in the Treasure Valley and 50mph in the Magic Valley. The mountains could see gusts topping 40mph, and brief whiteouts are possible. A Blizzard Warning remains in effect for the Owyhees and Camas Prairie.
Heavy snowfall is expected to continue in the mountains until Sunday morning, with mountain valleys receiving 1-2 feet of snow and higher terrain and ski resorts receiving 3-4 feet or more. The west central mountains will see the heaviest amounts.
In the lower valleys, there will be on and off snow showers until Friday, but a stronger system is set to impact the area on Friday night into Saturday. Several inches of snow are possible, especially in the Boise foothills. Temperatures will remain in the 30s for the rest of the week, and a drier and colder air mass will arrive over the weekend and into next week, with highs struggling to reach the 20s.
