Tuesday will be calm and mild during the day, but lingering cold air will bring lower overnight temperatures Tuesday night into early Wednesday morning. Frost/freeze conditions may be present in the Rogue, Applegate, and Illinois valleys, and frost conditions may be present in the Umpqua Valley. East side areas and Siskiyou County will also see lower overnight temperatures. Another weak system may bring more showers to west side areas Wednesday afternoon into Thursday, but hazardous conditions are not currently expected. A stable upper pattern will keep active weather generally out of the forecast for Friday and through the weekend, although occasional coastal and Cascades showers may develop if atmospheric moisture is available.
