Issued 320 AM MST FRI NOV 13 2026 Strong southwest flow will continue considerably warmer than normal temperatures today, before a strong upper-level Pacific trough moves inland later today, driving a cold front eastward across the area. Windy conditions, with gusts 20-40 mph, will be expected this afternoon ahead of and along the frontal passage, with exposed areas in southeast OR and far southwest ID near NV border seeing gusts 35- 50 mph. The cold front will bring widespread precipitation throughout the area, with valleys seeing rain and higher terrain areas seeing snow showers tonight through Saturday morning. Snow levels will mostly linger in the 6000-8000 ft above sea level range today, before gradually dropping into the 5000-7000 ft above sea level range by early Saturday behind the frontal passage. As such, snow accumulations will continue to be limited to high mountain peaks. Precipitation will gradually taper off from west to east Saturday morning as the front pushes out of our area. Winds are expected to lower down to 5 to 15 mph for most areas by Saturday morning. Cooler temperatures will be expected Saturday behind the frontal passage.
A brief period of mostly dry conditions and temperatures 5 to 10 degrees above normal will be in store on Sunday, as our area stays under a dry but strong southwesterly flow ahead of another incoming Pacific trough. The dry break will be short lived, as precipitation chances return across eastern OR Sunday afternoon and evening, before spreading eastward into southwest ID late Sunday night. With snow levels mostly hanging in the 6000-7000 ft above sea level range Sunday, light mountain snow showers and valley rain will be expected again with this second precipitation round.
Issued 320 AM MST FRI NOV 13 2026 Come Monday, the second Pacific upper trough digging into the northwest region will bring another cold front across the area. The system will bring a 50-70% chance of light precipitation Monday through Tuesday. Snow levels will drop down to 4000-6000 ft above sea level by Tuesday, lowest across eastern Oregon. A brief dry period is expected early Wednesday morning before the next system moves in. This deep upper-level low will move overhead from mid to late week, bringing colder air than previous systems. Uncertainty remains over this system's exact pattern as it either digs across our area as an upper trough or dive down into the California coast as a closed upper low. For now, precipitation chances remain at 40-70% late Wednesday through Thursday, with temperatures favored to cool a few more degrees and snow levels around 3000-4500 feet. Come early Friday, our area is projected to be under a strong northerly flow as the upper low digs into the Desert Southwest region. Light remnant mountain snow showers are possible Friday, as snow levels are projected to drop down to valley floor levels by Friday.
