Weather Underground Forecast for Sunday, April 24, 2016

A low pressure system will transition slowly across the Plains on Sunday, while another Pacific system affects the West Coast.

A slow moving low pressure system will trek eastward across the northern Plains. This system will usher light to moderate rain and high elevation snow across the central and northern Rockies. Winter weather advisories are in effect for northwest Wyoming and southwest Montana. Rain and snow will also spread eastward over North Dakota, northern Minnesota, the Great Lakes and New York. A cold frontal boundary extending southward will generate rain and thunderstorms across the northern and central Plains, as well as the upper Mississippi Valley. Severe thunderstorms will be possible in north central Oklahoma, eastern Kansas, eastern Nebraska, western Iowa and northwest Missouri. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Additionally, a wave of energy will initiate showers and thunderstorms across the western Gulf Coast. Most of the East Coast will avoid wet weather on Sunday due to high pressure over the Mid-Atlantic

Meanwhile, a trough of low pressure will slide across the West Coast. Rain and high elevation snow will develop over the Pacific Northwest, interior California and the Great Basin. Gusty winds will also affect parts of central and southern California. Most of the Southwest will experience dry weather on Sunday.
