Weather Summary

Weather Underground midday recap for Saturday, April 18, 2015

A low pressure system continued to impact the central third of the country on Saturday, while a ridge of high pressure persisted over the West Coast.

A strong low pressure system inched across the central Plains. This system ushered moderate to heavy snow showers across the central Rockies, as winter storm warnings were issued in Colorado and southern Wyoming. Pine Junction, Colo., reported a midday total of 32.0 inches of snow. Idledale, Colo., reported a midday total of 25.0 inches of snow. This system also interacted with a warm, muggy air mass from the Gulf of Mexico, which initiated heavy rain and thunderstorms across the Plains. Severe thunderstorm warnings were issued across the central Plains. Tahlequah, Okla., reported a midday total of 1.19 inches of rain. Joplin, Mo., reported a midday total of 1.17 inches of rain.

Meanwhile, a stationary front extended across the Gulf Coast. An onshore flow from the Gulf of Mexico collided with this frontal boundary, which resulted in heavy rain and thunderstorms across the western and central Gulf Coast. Flood warnings were issued over eastern Texas and the lower Mississippi Valley. Boothville, La., reported a midday total of 2.17 inches of rain.

A trough of low pressure shifted across the Northeast. This system ushered a mixture of rain and snow over northern New England.
