Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 459 AM EDT Mon Jun 10 2013 Valid 12Z Mon Jun 10 2013 - 12Z Wed Jun 12 2013 ...Soaking Rains Expected along the East Coast... ...Searing Heat Expected over the Plains... Another round of showers and thunderstorms is in store for the East Coast through Tuesday morning. An upper level trough is continuing its trek eastward towards the coast; along with it, a mature frontal boundary on the surface, currently in the Mississippi River Valley, will make its approach near the coast on Monday evening. Deep moisture from the Gulf of Mexico along with unstable air will enhance conditions to spawn widespread coverage of convection throughout the East Coast. Coverage will increase by Monday afternoon, and with such an abundance of moisture heavy rainfall can be expected especially along the New England and Middle Atlantic coastline. By Tuesday evening, the surface front will be well offshore and thus most of the shower activity will be in the northern portions of New England. Meanwhile, a frontal boundary draped along the Northern Plains will be a focus for showers and thunderstorms on Monday evening and will continue through Tuesday. An upper level ridge settles in across the Central Plains, and parts of central and western Texas, by Tuesday. Expect temperatures to reach the century mark for these regions as the upper ridge stays in place through Wednesday. Fanning Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
