SHORT TERM /Through Wednesday Night/
Issued 229 PM MDT MON JUN 8 2026 A cold front is advancing eastward across Oregon, preceded by extensive mid-level cloudiness. Ahead of the front, a very dry air mass is in place, with humidity values near 10 percent through much of the Snake Plain, amidst winds gusting to 20-30 mph. Scattered to widespread showers will develop through this evening, first across central Oregon, reaching the Treasure Valley after around 9 PM MDT. Although coverage will be high, rainfall amounts and intensity will be limited by how dry the sub-cloud layer is. In fact, the 18Z BOI precipitable water reading of 0.43" is close to the 25th percentile for the date.
QPF amounts are generally expected to range between 0.1-0.25" across the Snake Plain, and up to 0.25-0.5" in the Idaho Mountains. There's a 10% chance of 1.00" of rain occurring in McCall and over the West-Central Mountains.

By Tuesday morning, the cold front will advance eastward, but a more unstable air mass will take hold and support isolated thunderstorm development over the central Idaho Mountains - especially over Valley County. Otherwise, breezy conditions will occur from southeast Oregon into southern idaho, wind gusts approaching 30-40 mph during the afternoon. Temperatures will also be 5-10 degrees below normal through Wednesday. Near- freezing temperatures are possible Wednesday and Thursday morning in parts of southeast Oregon (including Burns and Baker City), and higher elevation valleys in Idaho (including McCall and the Camas Prairie). In fact, a dusting of snow is also possible across the mountains of Valley County as snow levels fall to around 5800 feet.

LONG TERM /Thursday through Monday/
Issued 229 PM MDT MON JUN 8 2026 An upper level ridge will build over the Pacific Northwest bringing dry weather and a warming trend.
