Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 346 PM EDT Tue Jun 28 2016 Valid 00Z Wed Jun 29 2016 - 00Z Fri Jul 01 2016 ...Severe Thunderstorms and heavy rainfall possible tonight for parts of the Northeast as well as the Central Plains... ...Monsoonal moisture continues across the Southwest, while the West remains hot and dry... A cold front moving eastward across the Northeast U.S. this evening will continue to provide a focus for showers and thunderstorms from the Mid-Atlantic to Maine. Some storms will be capable of producing heavy rainfall and severe weather mainly across the Northeast/New England. Both WPC and the Storm Prediction Center have placed a portion of this area in slight risks for flash flooding and severe thunderstorms. Rain will move off the Mid-Atlantic coast overnight, with lingering showers remaining on Wednesday across portions of New England near a developing wave of low pressure. The southern portion of this boundary will stall across the Gulf Coast and Southeast states the next couple of days keeping showers and thunderstorms, capable of locally heavy rainfall, in the forecast. The same frontal boundary extends west into the plains as a stationary front, where another batch of showers and thunderstorms is forecast overnight tonight. The SPC has highlighted this area as an enhanced risk for severe weather as a complex of thunderstorms is expected to develop near western Nebraska tonight, dropping southeastward into Kansas overnight. With significant moisture and instability in place, these storms may also be capable of producing flash flooding. Scattered showers and storms will linger across eastern portions of the Central Plains and into the Middle Mississippi Valley on Wednesday. Elsewhere, another system dropping into the Northern Tier will spread rain into the Midwest and Upper Great Lakes by Thursday. In the Southwest, monsoonal moisture streaming northward keeps mainly diurnally driven unsettled weather across the Four Corners region and Southern/Central Rockies through the next couple of days. And finally, out west, the weather should be hot and dry, with daytime high temps near 10 to 15 degrees above normal. Santorelli Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
