The weather is about to remind us that it's still winter!
A pair of low pressure systems are about to move into the region. With the cold air already in place, the snow will commence in the Treasure Valley late Friday. With the combination of the two low pressure systems moving through, we’ll see even more cold air pumped into the state. The front associated with the second low will also kick up winds of 20-30 mph in some areas of southwest Idaho. The bottom line is that winter has returned and it’s going to stay winter-like for the next week. Here’s how things should play out:
SATURDAY: Look for periods of snow in the Treasure Valley. The snow will be heavy at times in the mountains. We’ll also see breezy to windy conditions in the afternoon which could cause some blowing and drifting of snow in wind prone areas. Highs will only be in the 30’s.
SUNDAY: The potential for snow in the valley will be greatest in the morning. However, the unstable air behind the front will bring occasional snow showers. Breezy to windy conditions are expected. The mountains will still see steady snow which could be heavy at times.
MONDAY: There is still a chance of snow again! In fact, the models keep periods of snow in the forecast through Tuesday. Highs will remain in the 30’s.
ESTIMATED SNOWFALL TOTALS: The mountains above 5,000’ will see between 10-15” of snow with some areas possibly seeing more. The mountain valleys and passes below 5,000’ will see about 8-11” of snow. The Lower Treasure Valley will see about 2-4” of snow. The Upper Treasure Valley will see about 2-3” of snow. All these estimates are between now through the end of the day Sunday. The funny thing about estimating snowfall is that the second you think you really know what’s going to happen, some mini, micro process takes place and some areas get more while others get less.
POTENTIAL IMPACTS: Regardless of how much snow you end up getting, the cold temperatures will ensure that any snow that does fall will likely start accumulating on the roads. Please take that into consideration if you plan on traveling. If you go long distance, please be sure and check road conditions before departing. Otherwise, we’ll be watching.
