So far showers have eluded us for most of Saturday in the Treasure Valley but that is expected to change as we get through the rest of the night and into Sunday. Winds will die down a bit overnight and they will also help keep us mild for the rest of this evening.
Showers in the form of snow will continue overnight in the West Central and Central mountains. The Treasure Valley will see some rain between the 9 and 10 o'clock hours.
A cold front will pass through overnight into early Sunday which will drop snow levels, change the direction of the wind, and bring an ample supply of snow to the mountains. In fact, we have a Winter Weather Advisory for the West Central mountains and a Winter Storm Warning for the Central mountains through Sunday.
A rain snow mix early Sunday will turn to mostly snow in the Treasure Valley with that cold front, however, we are not expecting any accumulation in the valley. The mountains could see upwards of a foot of snow in some areas.
Look for lingering scattered snow showers on Sunday to finally taper off late Sunday night. By Monday we should be mostly dry but much colder every where across southern Idaho.
We will see a gradual drop in temperatures for Sunday but by Monday lows will dip into the mid-20s and highs will be just above freezing. Tuesday will be even cooler as overnight lows will be back in the low-to-mid-teens for the first time since December, marking the coldest temperatures of 2018. Highs that day will only be in the upper 20s.
Temperatures will begin to warm into next weekend by Wednesday, reaching the mid-40s by Saturday. A persistent low pressure system locked in place to our north will keep us in the realm of a series of weak waves of possible showers into next weekend.
