Lewiston, Idaho

Today we head off to the WA/ID border where we find Lewiston. Humorously, just across the border into WA we find Clarkson. I’m sure that’s totally a coincidence, right? Right.

At 605pm PST, the temperature at Lewiston, ID was 52 degrees with light rain falling. A cold front is shifting through the Pacific Northwest associated with an area of low pressure found over western Alberta. This front will continue pushing eastward through the region during the overnight hours and while widespread rain showers are found in the area currently, those will become fewer and further between as we pass midnight and into early Monday morning. A ridge of high pressure will nose over the region Monday afternoon into early Tuesday, but another frontal system looks to push into the Pacific Northwest Tuesday afternoon into Tuesday evening and will bring another round of rain to the Lewiston area by the late evening hours.The surrounding mountains will likely see some snow from this system, but Lewiston, lying lower in the valley floor, will likely just see a cold rain.
