Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 412 AM EDT Fri Jun 13 2014 Valid 12Z Fri Jun 13 2014 - 12Z Sun Jun 15 2014 ...Showers and thunderstorms will impact much of the East Coast ahead of an approaching front... ...Stormy weather will stretch across the southern Plains and Southeast... ...Pacific Northwest to the northern Plains can expect widespread showers with a strong front dropping through... Bountiful moisture ahead of an incoming cold front moving toward the East Coast will give way to active weather on Friday. As the front moves closer to the coast, numerous showers and thunderstorms will be present across the New England and Mid-Atlantic region. Precipitation is not expected to be organized in nature, however there is the potential for slow moving storms that could produce heavy rainfall. By Friday night, the front will push off the Mid-Atlantic and New England coast. Following the frontal departure, dry conditions with a drop in humidity will settle in the Mid-Atlantic. The same cannot be said for New England, as a surface low slowly moves northeastward. This will keep moderate showers around the region throughout most of the short term period. The southern half of the cold front bringing unsettling conditions to the East Coast will also impact the southern Plains and the Southeast. As the cold front drops towards the Gulf Coast, showers and thunderstorms will flare up along the boundary. With plenty of daytime heating and instability in place, these storms, particularly in Texas, could be strong to severe. The thunderstorms will come to an end in central and eastern Texas, but scattered showers and thunderstorms will continue in the Southeast through Saturday. A closed low in the mid-level of the atmosphere moving over the Pacific Northwest will slide eastward across the northern Plains. Light to moderate showers were already moving onshore early Friday morning, and this activity will become more widespread into Friday afternoon and Saturday. At the surface, an occluded front will move through the Intermountain West on Friday and the northern Plains by Saturday. As the showers taper off for the Pacific Northwest by Saturday morning, this is when the more intense showers and thunderstorms moving through the northern Plains will start. This activity is expected to progress eastward ahead of the front toward the Upper Midwest. Fanning Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
