Marine Weather and Tide Forecast for Skykomish, WA

SYNOPSIS
Lighter winds and mild temperatures for the weekend. Isolated showers and thunderstorms are possible along the Canadian Border. Warmer next week with an increasing risk for elevated fire weather conditions from gusty winds.

DISCUSSION
Evening update: Some adjustments to POP's were made for the rest of tonight, with the biggest change for the Lewiston and Camas Prairie area into the south ID Panhandle. A mid level wave tracking through the area combined with elevated instability has been sufficient for an expansion in shower coverage, along with a few thunderstorms as well over the Camas Prairie. POP's were increased based off current radar trends. A second area of instability over the Okanogan Highlands will gradually weaken this evening into the overnight with the loss of daytime heating. However lift from the incoming wave will lead to some activity persisting into the overnight hours, with the main focus near the Canadian border. For the bulk of the region (Central and NE Washington into the N Idaho Panhandle) dry weather will continue into the night. JW

AVIATION
06Z TAFS: VFR conditions will continue for all TAF sites through 06z Sunday. A weather disturbance tracking across the region tonight will result in a couple areas of showers. One tracking south and east of KLWS and another near the Canadian border.
Isolated thunderstorms have been observed in both of these areas, but are not expected to impact any of the TAF sites.
Drier air moving in Saturday will bring decreasing cloud cover to Eastern WA/N Idaho.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence for VFR conditions. JW
