Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 442 PM EDT Thu Aug 07 2014 Valid 00Z Fri Aug 08 2014 - 00Z Sun Aug 10 2014 ...Active weather will continue along a frontal boundary stretched from the Central High Plains to the Mid-Atlantic coast... A wavy frontal boundary stretched through the Nation's mid-section will continue to serve as a focal point for convection from the Central High Plains to the southern Mid-Atlantic coast. The best chance for any organized activity will be to the east of a surface low along the front...which is expected to steadily track out of the Middle Mississippi Valley on Friday and towards the Central Appalachians on Saturday. A rich supply of moisture feeding into developing storms could lead to heavy downpours and areas of flash flooding. Farther west along the wavy boundary...energy streaking northeastward out of the Southern Rockies Thursday evening could spark a second area of organized heavy rains and thunderstorms across the Central Plains Thursday night into Friday. Locations well north of the front should stay relatively cool and dry the next few days...while many locations south of the boundary will remain warm and humid. Anomalous moisture in place...combined with energy moving through aloft...will allow widespread showers and thunderstorms to continue over the Great Basin and Northern/Central Rockies; however...the threat for periods of heavy rains and flash flooding should begin to diminish.
