Late spring storm arrives this weekend

1 week ago | idahonews.com | Roland Steadham

CBS2 Boise — A significant change in our weather is poised to move into Western Idaho this weekend as a strong trough of low pressure moves in from the Pacific. Thursday will be sunny and warm. We'll likely notice the winds picking up in the afternoon and highs will reach the low 90's. Look for partly cloudy skies on Friday as a mostly dry cold front sweeps through the area. This will bring windy conditions to the area in the afternoon. The main low swings in on Saturday.

While the main storm cell is weakening, another batch of moisture over Central Oregon could triggers additional pockets of rain tonight and another line of thunderstorms tomorrow.
Recent storms have been busy in our local mountains

CBS2 Boise — While we have been mostly dry in the Treasure Valley, the mountains have been getting a lot of snow over the weekend! This snow stake at Tamarack shows over 14" of snow in 24 hours. That's a beautiful sight for our local mountains. But, over the last 48 hours, Tamarack has had 30", Brundage has reported 22" and Bogus received 18" of fresh powder. Our snowpack levels are definitely moving in the right direction.
Chilly air and storm to return this week

CBS2 Boise — Unseasonably warm temperatures will continue across Western Idaho through Tuesday with highs warming into the 60's. This will be in anticipation of another big change expected Wednesday as a series of fronts will move in from the Pacific Northwest. While highs in the 60’s sounds nice, we need to crank up the snow in the mountains again if we hope to end the season on a good note.
Rain/Snow showers expected in the morning

CBS2 Boise — A storm will move across Nevada tonight and Thursday. There is a chance of some of that moisture moving through the Treasure Valley around the morning commute and through the first part of the day. The showers will fall as a rain/snow mix. No accumulations are expected at this time as temperatures will be above freezing. The Owyhee mountains to the south of the Treasure Valley will see significant snow of 3-6” with up to 6-10” above 6,000’. High pressure will rapidly return on Friday.

CBS2 Boise — Treasure Valley resident, Justin Harrison went snowmobiling on Friday and sent me this picture from Mores Creek Summit. One picture tells a story and that story is that we are looking good for snowpack across all of Southern Idaho for right now. The following numbers do not take into consideration the additional 6-8” of snow we have had. For example, the Boise Basin is now 125% of normal snow for the season. The Weiser Basin is 135% and the Owyhee Basin is 120% of normal.
Major winter storm plows toward Idaho

Feb 12, 2025 | idahonews.com | Roland Steadham

CBS2 Boise — After days of blue skies and frigid temperatures, a significant change is expected in our weather on Friday as a strong winter storm moves in from the Pacific. We have two ingredients in place that will enhance the potential for the storm to make snow. First, is the frigid air trapped in Western Idaho. Highs have only been in the 20's and lows again tonight will drop into the single digits. So as the storm approaches, the air will be frigid and the ground is already in a hard freeze.
Frigid air expected before the next storm arrives on Thursday

CBS2 Boise — This week has given us a great volley of storms raising our snowpack levels to above normal readings once again. We're now averaging 125-138% of normal in our local snow basins. With more storms on the way this week, these numbers will look even better by next Sunday. But for now, it's about to get very cold and very dry before the next storm arrives. Look for sunny to partly cloudy skies on Monday with chilly temperatures. Daytime highs will only reach the low 30's.
Atmospheric River means much more rain and snow

Feb 2, 2025 | idahonews.com | Roland Steadham

CBS2 Boise — A persistent trough of low pressure has parked itself along the Pacific Northwest. As it spins counterclockwise it is pumping in a lot of moisture from the West Coast. This scenario is often referred as an "Atmospheric River". As temperatures get colder tonight, much of the valley rain will change over to snow. I do anticipate snow for the Monday morning commute. This will make for slick driving conditions in the Treasure Valley.
Are you ready for a big change in the weather?

CBS2 Boise — High pressure will keep the sun shinning through Wednesday with highs in the mid to upper 30's. The pattern has been too dry for too long. The last time we had measurable precipitation in the Treasure Valley was January 10th. If the computer models hold true, the high pressure will be replace by a trough of low pressure by the end of the week and that will open the window for storms to return to the state.
