Mountain snowpack levels improving after parade of storms

Heavy mountain snowfall over the past several weeks is starting to make a dent in our snowpack deficit. Looking at some of the current reading across the state the Weiser, Payette, and Boise basins have all made an improvement in the amount of moisture locked in the snowpack. It wasn't too long ago when these water basins were closer to values currently seen in the southwest region of the state.

An area low-pressure parked off of the Oregon coast has brought significant moisture to the region over the past 72-hours. One particular area that saw a tremendous amount of snowfall was Sun Valley. They reported 21 inches of snowfall in the past 48 hours. An area that hasn't seen too many storms this season, primarily due to the direction our storms have been coming from(the northwest) but did really well with this storm which brought up moisture from the southwest.

The same storm that brought heavy snow to our mountain regions has been pounding the eastern half of the state and northern Utah. The center of the storm is expected to move over southwest Idaho overnight, bringing occasional showers to the mountain regions, and slide east of the area by tomorrow afternoon. Most forecasts are calling for 3-7" of snow in the eastern valleys and 1-2' in the mountains of eastern Idaho and northern Utah.

As I mentioned before, the storm will move right over the Gem state through Sunday afternoon, the biggest impact on the Treasure Valley will be cooler temperatures and breezy winds. Wind speeds are expected to be 10-20 mph Sunday afternoon and temperatures will be in the low 40's. Our weather pattern turns quiet for the first half of the work week, our next storm will likely arrive on Thursday.
