.DISCUSSION... An upper low off the coast will gradually move eastward through Monday, with the broader upper trough impacting the area over the weekend.
Showers and thunderstorms will affect the Pacific Northwest over the next few days...mainly over central Oregon today, then central Oregon and the Cascades on Saturday. A Red Flag Warning remains in effect through this evening.
Thunderstorms look to become more wet through the weekend and some areas, especially the mountains and central Oregon could end up getting some decent rainfall amounts.
The biggest question remains about cloud-to-ground lightning strikes, and how many in a given area and what that impact will be on any new fire starts, especially on Saturday. Other questions are what impact smoke will have on thunderstorm development and if rain will alleviate concerns from lightning, at least in some areas.
Will need to keep watch on this to see if any fire weather headlines become necessary.
By Wednesday, more generally low (700-704- 705.
WA...None. &&
