LONG TERM...Sunday through Thursday

The upper-level trough will move further inland into the Great Basin Sunday, keeping the region in southwesterly flow aloft and precipitation chances 30-50%. Precipitation chances remain elevated until late Monday. Some long range guidance, including the ECMWF EFI, REFS, LREF, and soundings hint at thunderstorms along the Nevada border Sunday afternoon. Chances at this time are quite low (5-10%), but mentionable. The highest PoPs and QPF totals for this system will be south of the Snake River Plain to the Nevada border, as well as SE Oregon. The main discriminator between models is the speed of this system, with some indicating precipitation lingering around until Tuesday morning. Brief upper-level ridging will build in Tuesday afternoon before another upper-level trough moves into the area early Wednesday. Elevated PoPs will be back in the picture with assistance from a weak cold front that brings temperatures back to near normal.
