Weather Underground Forecast for Wednesday, April 23, 2014
A cold frontal boundary will move across the Intermountain West and the Plains on Wednesday, while a separate cold front will move over the Eastern Seaboard.
An active weather system will develop over the central and southern Plains on Wednesday as a cold front move across the region. This cold front will start off the day by moving across the Intermountain West. Rainy weather is expected across the central Rockies, while high elevation snow showers will be possible over the northern Rockies. As this system moves eastward, it will interact with a warm, muggy air mass from the Gulf of Mexico to produce strong to severe thunderstorms. Severe thunderstorms will be possible over northern Texas, western Oklahoma, Kansas and Nebraska, while scattered showers and thunderstorms will be possible across the central and upper Mississippi Valley, the northern Plains and the upper Midwest. The Gulf Coast and the Southeast will stay mostly clear of wet weather.
A separate cold front will push eastward over the Eastern Seaboard on Wednesday. An area of low pressure along the northern tier of the front will usher a mixture of rain and snow across the Northeast. Heavy snow will be possible in northern Maine.
Out west, an onshore flow from the Pacific will continue to push rainy weather across northern California, Oregon and Washington. A mixture of rain and snow is forecast to develop over the Cascades. High pressure over the coast of southern California will keep the Desert Southwest clear of precipitation on Wednesday.
