SHORT TERM...Today through Saturday (5/17)...Clouds are overspreading the region this afternoon as a weak front pushes onshore today. There are some returns showing up on radar over Coos and northern Douglas Counties, but so far nothing has measured according to surface observations. Breezy to gusty winds are expected this afternoon and evening, with gusts 15 to 25 mph most common and strongest east of the Cascades. Light precipitation (few hundredths at best) can be expected mainly north of the OR/CA border and across the higher terrain through tonight.

We'll remain under zonal flow Friday with drier conditions and seasonable temperatures that will be a few degrees warmer compared to today. Another trough is expected to move into the region Friday night through Saturday. This system will be quite similar to the one experienced earlier this week, thought with less precipitation. Expect breezy winds again Friday afternoon and evening as the trough approaches the region and even more so on Saturday as the trough moves overhead and enhances shower activity. Isolated thunderstorms are also possible Saturday afternoon, but the general consensus is instability will be greatest east of the Cascades, thus have maintained a slight chance to chance (15%-30%) of storms focused over far eastern Lake/Modoc counties.

This upper trough moves east of the region late Saturday, with precipitation chances diminishing for most of the area aside from along the coast and Cascades north of Crater Lake.

LONG TERM...Sunday (5/18) through Thursday (5/22)...Northwest flow persists through Sunday with a shortwave passes through across northern Oregon and Washington. This could maintain some shower activity across far northern areas, but most of the region will remain dry with cooler than normal temperatures.

Low impact weather is generally expected for the remainder of next week. Temperatures will rebound to seasonal normals, maybe a few degrees warmer with overall dry conditions expected. Some ensembles show a weak front pushing through the region Monday into Tuesday, so there is a slight chance of precipitation in the forecast for areas along and north of North Bend/Roseburg/Crater Lake. Any precipitation amounts with this front will be light, and wouldn't be surprised to see precipitation chances dwindle as the time gets closer. /BR-y
