A low pressure system will form over the California Monday, February 27, and into Tuesday, February 28, when it passes over the Mid-west. It will bring few brief flurries for high elevation mountains of California, Nevada, and Utah.
Monday Overnight into Tuesday, the system will become stronger and bring snow to parts of Colorado, Wyoming, South Dakota, Southern North Dakota, and parts of Minnesota. Some areas may start of as rain, but temperatures will cool and precipitation will gradually turn to snow.
The system will extend southward into Texas, Oklahoma, Arkansas, Louisiana, and Missouri, bring rain, possibly heavy, and possible thunderstorms.
Nebraska, and Kansas will experience very warm temperatures on the East wide of the storm, with temperatures around 10 C (50 F), bringing rain, possibly heavy. However, cooler temperatures will follow after the storm passes, but a lack of moisture will prevent any snow.
Most of the snow will push into Great Lakes Tuesday night into Wednesday. Around 5-20 cm may fall. Rain may fall at first, but temperatures will likely cool and change precipitation into snow, or at least mixed precipitation. Additional snowfall may occur near the Lakes due to lake effect squalls.
Heavy rain may fall along the East coast. Northeastern states may experience precipitation changing into snow or mixed precipitation by Wednesday night.
