Short Range Forecast Discussion...Correction NWS Weather Prediction Center College Park MD 558 PM EDT Wed Sep 14 2016 Valid 00Z Thu Sep 15 2016 - 00Z Sat Sep 17 2016 ...Heavy rain possible over the coastal Carolinas due to Tropical Storm Julia... Julia will slowly drift to the east-northeast as a tropical storm over the next couple of days. See the latest advisory from the National Hurricane Center for the most up to date storm track and intensity. Periods of heavy rainfall can be expected with this system, especially across the coastal Carolinas. The bulk of the rainfall is forecast for areas offshore; but 2 to 4 inches, with isolated higher amounts, will be possible along the South Carolina coastline by the end of the week. There is a moderate risk for excessive rainfall and flash flooding through at least Thursday morning. Much of the Northeast, Ohio valley and Mid-Atlantic will be cooler and drier as high pressure settles in behind once the cold front passes. A developing low pressure system will cross Wyoming/Colorado tonight and move eastward into the central/northern Plains on Thursday. Scattered showers are possible across the Northern and Central Rockies - the highest elevations may have a mix of rain and snow, or all snow. Areal coverage of showers and thunderstorms will increase across the central Plains and Midwest as the front pushes eastward into the Dakotas central Plains. Heavy rainfall may occur for portions of the southern High Plains, central Plains and Midwest/Upper Midwest along and ahead of the advancing front. Moisture over the Gulf Coast States and upper-level impulses will produce showers and thunderstorms through Friday afternoon.
