Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 424 AM EDT Fri Jul 01 2016 Valid 12Z Fri Jul 01 2016 - 12Z Sun Jul 03 2016 ...Heavy rain and strong to severe thunderstorms will be possible in portions of the Central Plains on Friday... ...An approaching cold front will bring a chance for severe weather across the Northeast and northern Mid-Atlantic states on Friday... ...Dry and unseasonably cool conditions expected for the Upper Midwest and Ohio Valley... Showers and thunderstorms will continue to develop along a frontal boundary stretched from the Tennessee Valley to the lee of the Central Rockies the next few days. The greatest threat for any organized areas of flash flooding and severe storms will be across Kansas on Friday and the Lower/Middle Mississippi Valley on Saturday...where impulses of energy rippling through aloft will combine with anomalous moisture setting up along the boundary. Farther north...a cold front will push out of the Great Lakes region on Friday...before clearing the New England coast early Saturday. Strong dynamics aloft could allow for severe weather within thunderstorms developing along and ahead of the boundary...especially as the front approaches the Northeast and northern Mid-Atlantic states on Friday. Surface high pressure sliding in behind the boundary will keep conditions dry and unseasonably cool across much of the Upper Midwest and Ohio Valley Friday and Saturday. Elsewhere across the Nation...another afternoon of shower and thunderstorm activity is expected across the Four Corners region Friday as well as to the south of a frontal boundary lingering over the southeastern U.S..
