LONG TERM...Saturday through Wednesday

An upper-level trough will move into the OR/CA border region Saturday morning, bringing southwest flow aloft. Shower chances increase from SE Oregon, beginning late Saturday morning into afternoon, and move into SW Idaho Saturday afternoon into evening. Precipitation chances will persist through Monday afternoon until the system moves further SE of the region, with chances around 30-50% areawide. Snow levels range from 5000ft near Baker City and McCall, to around 7500ft near the NV border with this system. Behind this system, upper-level ridging will build back into the area. This will bring spring-like temperatures, with valleys reaching the low to mid 60s on Tuesday or around 10-15 degrees above normal. Ensembles hint at a cold front moving through the area late Wednesday, with snow levels lowering to around 4000-5000ft and light snow accumulations over the mountains.
