Area Forecast Discussion National Weather Service Spokane WA 947 PM PDT Mon Jun 1 2020

SYNOPSIS. Skies will clear out tonight behind an exiting mid level front. Patchy fog is expected in the valleys of the Idaho Panhandle by Tuesday morning. A weather disturbance on Tuesday will produce showers along the Canadian border and breezy winds in the lee of the Cascades by early evening. The next good chance of showers and thunderstorms will arrive on Friday and continue into the weekend with temperatures cooling to below normal.

DISCUSSION.

Tonight through Wednesday: A weather disturbance is making a slow exit out of the Central Panhandle Mountains late this afternoon. Stratiform precipitaiton is falling along this frontal feature from the Camas Prairie to northwest Montana and this will be coming to and end shortly with the region continuing to dry out from the wet weekend. Patchy fog is possible for the mountain valleys near Deer Park, Priest Lake and portions of the Purcell Trench, as well as over the southern to central Idaho Panhandle valleys.

A westerly upper level jet will nose in toward the Northwest coastline on Tuesday and will propel a shortwave disturbance across southern BC. The bulk of the upper level dynamics associated with this wave looks to remain north of the border. We are carrying just a chance for afternoon showers near the Cascade crest and across the northern mountains. Otherwise, we are just looking at some increasing mid to high level cloud cover with mainly virga into the basin. This wave will also tighten the cross Cascade pressure gradient with breezy winds through the gaps. Nothing out of the ordinary with these winds as gusts will be in the 25-35 mph range through the Wenatchee River Valley, into Chelan, the Methow Valley and across the southern portion of the Okanogan Valley and Waterville Plateau.

Wednesday will continue to be dry with increasing higher clouds, but should at least see filtered sunshine. Temperatures will hold right around normal for early June with highs in the 70s to low 80s. /SVH

Wednesday night through Friday: A dry zonal flow aloft will be over the Inland NW for much of the work week with high pressure at the surface and light winds. By Friday, the flow aloft backs to the southwest as a low drops down the B.C. coast. This southwest flow will bring an increase of clouds to the region, especially across southeast Washington into north Idaho along with a small chance of showers. Overall, temperatures will gradually warm each day, creeping above normal late this week.

Friday night through Monday: More unsettled weather returns as the upper low off the B.C. coast pivots inland and rotates over the Pacific NW through the weekend. Shortwaves in the circulation will enhance convection especially in the afternoon and evening hours with a chance of thunderstorms. The confidence with the timing of these shortwaves is low, although expect an increase in precipitation late Friday night through Saturday with a cold frontal passage with breezy winds. The upper low will settle over the region on Sunday with showery conditions region-wide and more breezy winds especially for the Columbia Basin. The best chance of precipitation will be in the mountains, especially from the Blue mountains into the central Idaho Panhandle with the possibility of moderate rainfall. Temperatures will cool below normal through the weekend with Sunday looking to be the coolest day of the week. /rfox.

Hydrology: Recent rain and high mountain snow melt have led rises on many rivers. Several have crested and river levels are falling, although still have concerns in north-central WA. The Okanogan at Tonasket should be cresting tonight and begin to fall below flood stage by tomorrow night. The Kettle at Ferry experienced a sharp rise and should reach moderate flood stage tonight before falling back down. The dry and near seasonal weather for the next several days should allow these rivers to continue to fall this week. Still monitoring the Kootenai at Bonners Ferry and the Pend Oreille downstream of Albeni Falls Dam where releases will keep these rivers near bank-full this week. /rfox.

AVIATION. 06Z TAFS: Clear skies tonight and decreasing winds will result in patchy fog in the NE WA mountain valleys and ID Panhandle early tomorrow morning. Fog is not expected to impact TAF sites, but not out of the question for KSFF, KCOE, and KLWS. Mid to high level clouds will begin to move across the region in the late morning hours. Winds will pick up again Tuesday afternoon with gusts of 20-30 kts possible at KEAT, KMWH, and KGEG. JS

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
