Weather Synopsis for Thursday & Sunday
The Pacific Northwest sits in the middle of split upper level flow, with high pressure anchored over British Columbia and a closed low off the Oregon coast and the storm track passing far to our north or south. A pattern of marginal atmospheric instability should lead to isolated to scattered afternoon mountain showers for the next several days. Forecast models diverge on how much influence the closed low vs. higher pressure to our north will exert over the forecast area. Areas closer to the low including the south Washington Cascades and Mt. Hood seem like a better bet for showers with colder air aloft translating into more instability. A fair bit of high and mid clouds even as afternoon cumulus wane will make it hard to pin out a truly clear period overnight. Winds over the next two days will be light in this pattern as well.
Despite precipitation in the forecast, freezing levels will be indicated since precipitation amounts are expected to be generally light. For areas that do see afternoon showers, snow levels will fall roughly 1000 ft below the forecasted freezing levels.
