Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Sat May 19 2018 Valid 00Z Sun May 20 2018 - 00Z Tue May 22 2018 ...Widespread shower and thunderstorm activity will continue from the southern and central Plains to the East Coast... ...Dry and cool conditions expected with a surface ridge while it builds over the north central U.S.... ...An amplifying upper trough will bring unsettled weather and below normal temperatures to portions of the western U.S.... Widespread showers and thunderstorms will continue to develop within a warm and moist airmass in place from the southern and central Plains to the eastern U.S. The greatest threat for any organized areas of heavy rainfall or strong to severe thunderstorms will be from central Texas into the Middle Mississippi Valley as an impulse of energy aloft ejects northeastward out of the central Rockies Saturday evening. As the energy and an associated weak surface wave track eastward on Sunday, the chance for heavy rain and strong thunderstorms will shift into the Ohio Valley.
