BOISE, Idaho — After several days in a row with measurable rain in the valleys and several inches of snow in the mountains, drier conditions settled in briefly Monday morning and afternoon, another round of rain and snow will roll through thanks to the last in what has been a parade of low pressure systems to skirt our area.
Monday will start off drier and sunnier, but additional showers are expected in the afternoon/evening hours as another low pressure center approaches the Gem State. While the core of this system is expected to remain to the north, a cold front with accompanying rain and snow showers will swing through Monday afternoon/evening and early Tuesday, with a few flurries possible down to the Boise foothills as snow levels drop early Tuesday morning.
Scattered showers could linger through midday Tuesday but it will likely be the wind that is the bigger weather worry on Election Day, with a frigid northwest wind gusting up to 40mph at times across the I-84 corridor. That means anyone headed to the polls on Tuesday will want to bundle up bigtime, especially if you find yourself waiting outdoors at your polling place.
A high pressure ridge begins to increase in strength on Wednesday, locking in some colder air in valleys and setting the stage for a cold and dry stretch. From Wednesday through the rest of the week, mornings look particularly frigid, with lows in the 20's in the valleys, meaning extra layers at the bus stop or for your morning walk will definitely be needed. Inversion conditions also look possible as the high pressure ridge traps colder air at the surface with stagnant conditions likely through the end of the workweek.
