- The Storm Prediction Center, which posted a level 2 of 5 risk for Monday through midweek, warns of large hail up to 2 to 3 inches, damaging winds and possible tornadoes from the Upper Midwest into the Great Lakes.
- A second zone of risk in Texas and Oklahoma could see storms fire along a dryline Monday, with forecasters noting the potential for isolated supercells.
- Winter storm warnings in the Sierra Nevada brought several feet of snow over the weekend, with forecasts up to about 4 feet and ridge gusts near 130 km/h, and critical passes such as Donner Pass and Echo Summit facing chain controls and possible closures.
- NWS offices and local authorities urge people to avoid nonessential mountain travel and to carry tire chains, warm gear, lights, and 24 hours of food and water if a trip cannot be delayed.
- Consecutive Pacific lows continue to push inland toward the Great Basin and Rockies, keeping the West unsettled for several days as the same pattern feeds multiple rounds of severe storms in the central U.S.
