9. 48 Hour ForecastIssued 1500L08/15/2013 SYNOPTIC OUTLOOK: High pressure will center over the Mid-Atlantic today, providing dry and cool weather through tomorrow afternoon. High pressure will shift off the coast tonight as a frontal boundary well to our south begins to move north as warm front tomorrow afternoon. Southerly flow aloft will develop over the region tonight, allowing for an abundance of moisture to overspread the region. A combination of the moisture combined with warm-air advection will overrun the warm front allowing for scattered showers to develop over the region tomorrow afternoon into the evening. Showers will become more widespread Saturday, especially during the afternoon as several upper-level shortwaves interact with the front. An upper-level trough will remain over the eastern US, allowing for unsettled weather to continue into early next week. 48 HR TERMINAL FCST: FRI 05L SCT050 BKN250 P6SM.
