Weather Underground Forecast for Monday,July 18,2016
A cold front will generate active weather in the Midwest on Monday, while a ridge of high pressure amplifies over the Plains.
A cold frontal boundary will extend southwestward from the upper Great Lakes to the central Plains. As this frontal system transitions eastward, it will collide with moisture-rich air. This collision of air masses will produce rain and thunderstorms over the central Plains, the middle Mississippi Valley, the Midwest, the Mid-Atlantic and New England. Severe thunderstorms will be possible in Ohio, western Pennsylvania and western New York. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain will bring threats of flash flooding to eastern Kentucky, southeast Ohio and West Virginia. Thunderstorm activity will also persist across parts of the Southeast and the Gulf Coast.
Meanwhile, a high pressure system will amplify over the southern Plains. Hot and humid air will dominate much of the Plains and the Four Corners. Monsoonal moisture and daytime heating will trigger showers and isolated thunderstorms over parts of the southern Rockies and the Desert Southwest.
Additionally, a Pacific system will stall out over the coast of the Pacific Northwest. Temperatures will be 5 to 15 degrees below normal over portions of the Northwest. This system will also stir up showers and stray thunderstorms across the region on Monday. Most of California and Nevada will experience warm and dry weather.
