Marine Weather and Tide Forecast for Manson, WA

SYNOPSIS
Today will remain breezy and dry with west to northwest winds.
Winds decrease further on Thursday, but temperatures remain warm and conditions dry into the weekend. A cold front moving through over the weekend will bring breezy to gusty winds across central Washington, and will bring a return for increased fire weather concerns. Little to no precipitation is expected through the middle of next week.

DISCUSSION
Wednesday through Friday: Fire weather concerns continue today, though at an elevated level rather than the critical levels seen yesterday. Breezy wind gusts 20-30 mph will be seen across the Inland Northwest through this evening before relaxing, and will be combined with temperatures in the mid to high 80s and minimum relative humidity values in the high teens to mid 20s. Main impacts seen will be that new and ongoing fires may quickly spread as winds increase through the day. While skies will be mostly clear, smoke and haze from localized wildfires may impact some areas through the day, but this will largely depend on fire activity. An upper-level shortwave moving across NE Washington and the northern Idaho Panhandle will bring low chances of elevated light showers across these areas this afternoon.

A broad ridge setting up just off the PNW coast will bring warming temperatures through the next couple days. Moderate HeatRisk will return to the region by Friday, especially across the Spokane/Coeur d'Alene and Columbia Basin areas. Moderate HeatRisk impacts all those sensitive to heat without access to adequate cooling or hydration.

Saturday through Sunday: On Saturday, a trough will move through the region and usher in a dry cold front. While this cold front will not be as strong as the one earlier this week, winds will still increase, particularly across the Cascade gaps, Columbia Basin, and Okanogan Valley areas, where gusts 35-40 mph are anticipated Saturday night into Sunday. Wind gusts across the eastern third of Washington and through the Idaho Panhandle will reach 20-25 mph.
Relative humidity values will drop into the teens, bringing a return of elevated to critical fire weather conditions. Trends will be monitored as we approach the weekend to see if fire weather or wind headlines will be needed. Temperatures will decrease by a few degrees Saturday and Sunday, but remain in the low 80s.

Monday through Tuesday: After the trough moves through, the broad ridge will set back up over the west coast and begin strengthening again. This will increase temperatures and keep conditions dry through at least the middle of next week. By Tuesday, temperatures are expected to be in the low 90s, resulting in Moderate HeatRisk throughout the region. The CPC shows increased chances of higher than normal temperatures for both its 6-10 and 8-14 day outlook and is in alignment with the clusters, which show good agreement in signaling continued ridging and higher heights over the area.
