Wet and snowy weather persisted in the West and a few showers moved across the Northern Plains.

Two weather features merged over the West Coast as one trough of low pressure off the coast of California moved onshore, and another stronger system dropped in from the Gulf of Alaska. These systems in combination pushed abundant moisture onshore from the Pacific Ocean and produced scattered rain showers across most of California, Oregon, and Washington.

Once moisture from these systems reached the cooler temperatures in the mountains, rain showers turned to snow showers at the highest elevations. Snowfall accumulations in the Sierras ranged from 4 to 8 inches, while the Cascades saw 1 to 3 inches. Rainfall totals across California ranged from half an inch to an inch, with more at higher elevations.

Heaviest rainfall was reported at Redding, Calif., with a total of 1.48 inches. High wind advisories were issued across the Pacific Northwest and northern California as the associated cold front brought strong and gusty winds. Highest elevations saw gusts from 35 to 45 mph. Strongest winds were reported at Wenatchee, Wash., with a gust up to 56 mph.

East of this activity, a weak trough of low pressure advanced through the Northern Plains and kicked up a few scattered rain showers. Temperatures dropped below freezing in parts of North Dakota, thus, these areas saw snow showers overnight and in the early morning hours.

Meanwhile in the Southeast, scattered showers and thunderstorms developed just offshore of eastern Florida through the Carolinas as a trough of low pressure lingered just east of region. Most precipitation associated with this system remained offshore, but a few showers and thunderstorms reached into the coastal areas.
