Expect another wet, snowy day in the Western U.S., while thunderstorm activity declines Sunday in the East. A low pressure system and associated cold front that brought heavy rain, snow, and strong winds to the West Coast continues moving eastward into the Rocky Mountains. Once this system moves inland, limited moisture will bring an end to heavy rain and snow showers. Expect light and scattered snow showers to develop across the Great Basin as well as the northern and central Rockies through Sunday evening. Strong winds will develop ahead of this system, gusting from 50 to 60 mph through high mountain passes.
In the Plains, high pressure will continue to build from the South for another unseasonably warm, dry day. Temperatures will ascend into the 70s across parts of the Midwest and northern Plains, while the central Plains and mid-Mississippi River Valley will see highs in the 80s. These temperatures range from 20 to 30 degrees above seasonable. Dry, warm conditions with strong winds will keep fire danger high across the Plains.
Further East, a low pressure system will lumber off into the Atlantic, allowing a high pressure to build in. This will push moisture away to the southeast, ending thunderstorm development across the East. In the Northeast, however, a low pressure trough in eastern Canada will dip into the Great Lakes, kicking up scattered rain showers by evening.
Temperatures in the Lower 48 states ranged Saturday from a morning low of 6 degrees at Clayton Lake, Maine, to a high of 93 degrees at Junction, Texas.
