FRIDAY, MAY 18 Discussion
Upper level trough and surface cold front will move across the Divide on Friday with widespread showers and isolated thunderstorms. Temps will be slightly below normal. Transport winds will be moderate from the west-northwest. Smoke dispersion should be GOOD or better all locations.
Extended outlook:
The ridge finally gets broken down and temps should return to normal with some rain showers along the frontal boundary Thurs-Fri. Friday will be unsettled with more showers. West-southwest flow will dominate the weekend as another short lived ridge re-builds with more warm and dry conditions. Mid range models show another wet system breaking down the ridge on Tuesday. Smoke dispersion should be GOOD for the next few days.
