Weather Summary

Weather Underground Forecast for Thursday, April 24, 2014

Active weather continues across the Northern states on Thursday as multiple weather features continue moving eastward throughout the day. A low pressure system over the Plains will continue advancing northeastward over the upper Midwest and Great Lakes on Thursday, producing scattered showers. Cooler temperatures to the north will allow for some of these showers to turn to freezing rain and snow showers, mainly across the Great Lakes region. Meanwhile to the south, the low pressure system will create a strong cold front that extends southward across the Mississippi River Valley. Throughout the day this front will slide eastward, bringing showers and thunderstorms to the Midwest and into the Lower Mississippi River Valley. Late Thursday night these storms will move into the Ohio and Tennessee Valleys. There is a slight chance that severe thunderstorms will develop along this front, with main threats being strong winds and large hail, with possibly a tornado or two. Rainfall totals along this front will range from a half of an inch to an inch, with up to 2 inches possible in areas of severe thunderstorm development.

Meanwhile out West, a low pressure system off the coast of British Columbia will continue advancing eastward, pushing abundant moisture into the Pacific Northwest. This system will create a cold front that stretches southward, bringing precipitation to the West Coast. Expect This more rain showers and high elevation snow showers across Oregon and Washington, moving southward into northern and central California by Thursday night. Snowfall levels across the Cascades will rise to 5,000 feet, but are expected to remain above 8,000 feet for the northern Sierras on Thursday, lowering on Friday as cooler air slowly moves in from the north.
