Weather Underground Forecast for Tuesday,April 7,2015

An area of low pressure will affect the West Coast on Tuesday, while a cold front will extend from the central Plains to the Northeast.

A low pressure system will inch south southeastward over northern California. This system will draw moisture from the Pacific Ocean, fueling moderate to heavy precipitation across central and northern California. Winter storm warnings are in place for the central and northern Sierra Nevada, as well as the southern Cascades. Snow accumulation will exceed one foot across the two ranges, while some areas could experience up to two feet of snow. Lighter showers will be possible across portions of Oregon, Washington and southern California. Additionally, a wave of low pressure will slide across the Intermountain West. This system will bring 4 to 6 inches of snow to the Ruby Mountains, the Tetons and the Bitterroots.

Meanwhile, a cold frontal boundary will stretch across the central Plains, the upper Midwest and southern New England. Moisture will overrun this frontal boundary, bringing chances of snow and mixed precipitation to the northern Plains, the upper Midwest, the Great Lakes, the northern Mid-Atlantic and New England.

Just to the south, an onshore flow from the Gulf of Mexico will fuel disorganized showers and thunderstorms across parts of the central and southern Plains, the middle Mississippi Valley, the Tennessee Valley, the Ohio Valley, the Mid-Atlantic and the Southeast. Due to saturated soil across the Ohio Valley, there will be chances of flash flooding in southern Ohio, northeast Kentucky, West Virginia and western Virginia.
