SHORT TERM /Through Tuesday Night/

Issued 246 PM MDT SUN OCT 11 2026 An upper level trough over eastern OR will keep conditions cool and unsettled through Monday. Showers will mainly be confined to southwest Idaho with the highest chances of precipitation over the higher terrain and Magic Valley. Eastern OR will generally remain dry, with a slight chance of showers in far SE Oregon. Similar conditions on Monday as the trough remains nearly stationary. Monday will be the coolest day of the period. By Tuesday the trough will move into southern NV and UT with a chance of showers mainly along the NV border and Magic Valley through Tuesday. Temperatures will warm around 10 degrees as the upper level trough moves SE.

LONG TERM /Wednesday through Sunday/

Issued 246 PM MDT SUN OCT 11 2026 A warming and drying trend will persist Wednesday through the end of the period. As the low that brought all the weather in the short-term departs to our east, a Pacific ridge will build in, shifting east to be over the Great Basin by the weekend. As a result, temperatures will warm to be 5-10 degrees normal come the weekend.
