BOISE, Idaho (KBOI) — A series of weak storm systems have provided some relief from our inversion this past week. A cold front passed through the region early Saturday which allowed for enough mixing in the atmosphere to move out the colder air, temperatures reached the mid-40’s for many lower valley locations. Unfortunately, it’s a short-lived event and highs for New Year’s Eve will likely remain around freezing. If you have plans to take part in outdoor activities to ring in the New Year, be prepared for your typical bone-chilling temperatures. New Year’s Eve will be dry but temperatures will be in the low 20’s for much of the night.
Into the New Year, a ridge of high pressure will move over the region which will allow for an inversion to strengthen once again over the valleys. A gradual decline in daytime temperatures is expected next week with highs in the mid to upper 20’s starting on Monday, and temperatures will remain below average through the end of the week. So, we begin 2018 the same way we left 2017, only with a new batch of cold air. As with any inversion, the mountains will see gradually warmer temperatures over the next week, not the best news for skiers and snowboarders.
The next chance for new snow doesn’t arrive until the end of the week. Most models are hinting at a storm moving through late Friday into Saturday, the good news is that it could be a set up for a more active weather pattern for the following week. The forecast is still far out and could change quite a bit at this point, but we really could use a few feet of fresh snow in our local mountain ranges to help with the snowpack.
Have a safe and Happy New Year!
