Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 408 AM EDT Tue Aug 4 2015 Valid 12Z Tue Aug 4 2015 - 12Z Thu Aug 6 2015 ***Showers and thunderstorms from the northern Plains to New England*** ***Less thunderstorm coverage across the southeast U.S.*** ***Heat wave ending for the Pacific Northwest*** A cold front progressing eastward towards the East Coast is expected to have a broken band of showers and storms from the southern Appalachians to eastern New England on Tuesday. Some of these storms may be strong to severe and produce locally heavy rainfall. Cooler air filling in behind the front will result in a return to more pleasant conditions for the eastern U.S. by the middle of the week. After several days of heavy rain and thunderstorms across Florida and adjacent parts of the southeast U.S., things will be less active going into Tuesday and Wednesday as the surface trough weakens. The heaviest rainfall should remain offshore over the Gulf Stream waters. However, diurnally driven convection remains likely each afternoon near the Gulf Coast. Some storms are expected to develop across portions of the Pacific Northwest and the northern Rockies. A cold front dropping from the northwest will begin to impact the region, bringing an end to the stretch of well-above normal temperatures. Thunderstorms are also expected to develop across the central Plains and extending into Missouri. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
