SHORT TERM . Tonight through Wednesday . Mostly dry and calm conditions with a gradual warming trend through the short term forecast.
Today, breezy to occasionally gusty winds will continue in the Grande Ronde valley while the rest of the forecast area will continue to see mostly clear skies and calm conditions. Tonight and tomorrow, upper level shortwave passing through northern WA will flatten upper level ridge and clip the WA Cascades with an isolated snow shower or two near the crests. Meanwhile an upper low digging south then east offshore will push ridge axis further east over the Rocky Mountains and Great Plains region Tuesday and Wednesday. This synoptic pattern will otherwise keep a generally dry zonal flow over the forecast area through Wednesday night, then turn southwesterly aloft as upper low moves ashore in southern CA Wednesday. Dry flow aloft will keep the forecast area fairly dry with occasional partly cloudy conditions near mountain areas, while southwesterly flow aloft will filter in warmer air into the region. Lawhorn/82
LONG TERM . Thursday through Monday . Dry southwesterly flow aloft and warming trend will continue Thursday into Friday as upper level trough deepens in the eastern Pacific and upper level ridge strengthens over the central CONUS. Friday will likely be the warmest day this week, with afternoon highs reaching the lower to mid 60s outside the mountain areas. Friday, upper level trough over eastern Pacific will start to push onshore with leading frontal boundary, then move across the forecast area Saturday. There's general agreement across deterministic and ensemble members that most of the precipitation will be light rain turning to light snow Saturday and limited mainly to the mountains. However, GFS deterministic/ensemble members want to push this system across the forecast area Saturday morning, while ECMWF deterministic/ensemble timing is late Saturday afternoon. Timing of this system will determine timing of precipitation across the eastern mountain zones as well as when breezy conditions associated with frontal boundary start to develop. For this forecast package, have gone with breezy winds developing late morning through the afternoon with precipitation starting late morning for eastern mountains. Beyond Saturday, another upper level trough will dig south offshore and eject shortwave energy over the forecast area Sunday and Monday. Any snowfall with this trough will be fairly light and limited to mountain zones. Temperatures will be on a gradual cooling trend starting Sunday with afternoon highs in the mid 40s to mid 50s Sunday and Monday. Slight rises in rivers and streams can be expected into the weekend, however, with the lack of any impactful precipitation there is minimal to no concern for sharp rises. Lawhorn/82
AVIATION . 00Z TAFS . VFR conditions will prevail through the period. A ridge of high pressure will be over the area with sct- bkn mid and high level clouds. Winds will generally be under 10kts. 93
