Weather Underground midday recap for Thursday, April 17, 2014
A cold frontal boundary approached the Pacific Northwest on Thursday, while a separate frontal boundary extended across the Southeast.
A cold front approached the northwestern corner of the country on Thursday. This system pushed rainy weather across Washington, Oregon, Idaho and parts of northern California, while a mixture of rain and snow developed along the Cascades and the northern Rockies. Quillayute, Wash., reported a midday total of 0.70 inches of rain, while Astoria, Ore., reported a midday total of 0.54 inches of rain. High pressure kept the Southwest and the Great Basin warm and dry, as temperatures ranged between the 70s and 80s across the southern California and Arizona deserts. Chandler, Ariz., recorded a midday high of 84 degrees.
A separate cold front extended from the southern Plains to the upper Midwest. Low pressure along the northern end of the frontal boundary ushered snow showers across northeastern Minnesota, northern Wisconsin and northern Michigan. Scattered rain and snow also moved across parts of the northern Plains, while a line of showers inched across the southern Plains.
Meanwhile, a low pressure system began to develop along the western Gulf Coast. This system brought moderate rain and thunderstorms to southern Louisiana, while scattered showers popped up along the coast of Texas. Just to the east, heavy rain and thunderstorms formed along the southern tip of Florida, as Ft Lauderdale, Fla., reported a midday total of 0.96 inches of rain. The majority of the East Coast avoided precipitation on Thursday.
