Tonight through Thursday, a cold upper level will keep our weather cool and showery. A deep trough of low pressure is moving down the West coast and expanding. By tomorrow, it pivots into north Idaho, allowing a moist northeast flow to spill down from British Columbia. We can expect more cloud cover and spotty showers to increase from northwest to southeast through Thursday.

Winds will also increase out of the north by Thursday afternoon as cool temperatures persist. Most of the moisture tomorrow though will stay south of our area but we could see some scattered shower activity. The upper level low will slowly move through the region through Friday as high pressure begins to nose into the region from the west.

Temperatures will remain below normal for Friday and slightly below normal on Saturday but will begin to warm a few degrees each day. By Sunday and into next week that area of high pressure will bring us close to normal high temperatures, mostly sunny skies and light wind.
