AgWeatherNet Outlook for November 8 to November 14, 2021

Active pattern continues with repeated systems taking aim at the Pacific Northwest

Mark Ingalls, AgWeatherNet Field Technician

Synopsis:

The next disturbance to impact the region will be a warm front spreading rain inland and rising mountain snow levels overnight. It will be quickly followed by a cold front by Tuesday morning to keep rain in the picture and bring snow levels back down to around pass level. Things dry out during the day Tuesday east of the Cascades. Despite a break between disturbances Wednesday, areas in and west of the Cascades are likely to continue seeing rain and mountain snow.

A deepening trough offshore and ridge over Washington are forecast to send a Pineapple Express into the state, bringing more rain statewide. With the source of this moisture being well south, snow levels are expected to rise significantly. Look for rain through the weekend west of the Cascades, but it is possible that Saturday and Sunday will be dry to the east if the ridge becomes the more dominant pattern there. If this does occur, fog in low elevations is possible.

Discussion:

Due to illness, this section will be omitted from the outlook today. Sorry for the inconvenience.
