Weather Underground Forecast for Saturday,June 21,2014
A cold
frontal boundary will extend from the Great Basin to the northern
Plains on Saturday, while a separate frontal boundary will stretch from
the upper Midwest to the Mid-Atlantic.
Active weather will impact the nation’s midsection on Saturday. As a warm, humid air mass moves northward from the Gulf of Mexico, it will collide with a cold front extending from the Great Basin to the northern Plains. Strong to severe thunderstorms will develop across a handful of states, as severe thunderstorms will be possible over South Dakota, Nebraska, northeast Colorado, northern Kansas, southwest Minnesota, Iowa, Missouri and Illinois. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Scattered showers and thunderstorms will also be possible across the Intermountain West and the southern Plains. A separate frontal boundary stretching from the upper Midwest to the Mid-Atlantic will bring stormy conditions to the Ohio Valley, the Tennessee Valley, the Gulf Coast, the Southeast and the Mid-Atlantic. The northeastern corner of the country will stay mostly clear of wet weather.
Out west, a ridge of high pressure will continue to build over the eastern Pacific. This system will bring warm, dry conditions to the Desert Southwest. Temperatures are forecast to approach 110 degrees across the southern California and Arizona deserts on Saturday.
