Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 334 AM EDT Tue May 10 2016 Valid 12Z Tue May 10 2016 - 12Z Thu May 12 2016 ...Mainly dry for both coasts and stormy for the Plains... The main weather maker across the nation will be a strong low pressure system over the central U.S. through the middle of the week. An occluded surface low over the Dakotas will provide for widespread moderate to heavy rainfall across the northern Plains and snow for the mountains of Wyoming and Montana. Farther to the south, another surface low along the trailing cold front will also produce widespread showers and thunderstorms extending from Texas to the Ohio Valley. Some of these storms could be severe at times, and also produce localized flash flooding. Temperatures are expected to be below normal across much of the Intermountain West with an upper level trough in place, and also for the Northeast U.S. which will be under the influence of a Canadian surface high. Warm and humid conditions are expected south of a stationary frontal boundary which will extend from the Ohio Valley eastward to the Outer Banks of North Carolina. Highs in the 80s to low 90s along with noticeable humidity will be commonplace across the Deep South and the Southeast states.
