Tropical Storm Julia is forecast to drift eastward over the Atlantic, east of South Carolina, and weaken into a tropical depression. A stalled front over the southern Mid-Atlantic will help generate a few showers and thunderstorms through Friday night. The heaviest rainfall associated with Julia will be over the Ocean; however the coastal Carolinas could pick up a little more rain over the next couple days. See the latest advisory from the National Hurricane Center for the most up to date track and intensity of Julia. Tropical moisture over parts of the Gulf Coast States into Florida along with daytime heating will aid in producing late afternoon and evening showers and thunderstorms along the Gulf Coast and Florida. Additionally, monsoonal moisture and daytime heating will produce showers and thunderstorms over parts of the Central/Southern Rockies also tonight through Friday evening. Meanwhile, an upper-level low over the Northern Rockies/High Plains will advance toward the northern Plains/Upper Mississippi valley over the next couple of days. Scattered to widespread showers and thunderstorms are forecast to develop along and ahead of this system. Conditions will be favorable for severe thunderstorms and heavy rainfall across portions of the Plains and Midwest/Middle Mississippi valley. On Friday, the showers and thunderstorms will expand into parts of the Upper Great Lakes/Western Ohio Valley and into parts of the Tennessee Valley. The highest 3-day rainfall totals are forecast from northern Texas, across the Ozarks and up the Ohio valley - 1 to 2.5 inches will be common with isolated higher amounts possible. The threat for flash flooding will be elevated for this region into the weekend. Campbell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
