Short Range Forecast Discussion...Amended NWS Weather Prediction Center College Park MD 825 AM EDT Sat Sep 20 2014 Valid 12Z Sat Sep 20 2014 - 12Z Mon Sep 22 2014 ...Heavy rain will continue to impact New Mexico and Texas... ...Atlantic coastal low to bring showers and thunderstorms to Florida and the Southeast coast... The risk for excessive rainfall and the threat of flash flooding across southeast New Mexico and the Big Bend/Texas Panhandle through early Sunday morning remains, as remnant moisture from Odile continues to stream over portions of southern New Mexico and Texas---with showers and thunderstorms focusing along a stationary front draped across the southern half of the Lone Star state. This stationary front extends eastward into the Gulf of Mexico and the Florida peninsula to the Atlantic Ocean. A surface wave has developed on the Atlantic side of the stationary front, and will slowly migrate northeastward along the coast of Georgia and the Carolinas this afternoon and tonight. On Sunday, the system will track from the Outer Banks to the Gulf of Maine. Current forecasts indicate the bulk of the precipitation will remain offshore, but occasional showers and light rain will affect the majority of the immediate East Coast shoreline. Elsewhere, a series of Pacific disturbances will race along the US-Canadian border, with showers and thunderstorms expected today and tonight from the Great Lakes to northern New England along its weakening cold front. A second disturbance will move across the northern Plains tonight and reach the Ohio Valley by late Sunday morning. Its cold front will spread a drier airmass into the Plains and Midwest by the end of the weekend---meanwhile its leading edge pushes through the eastern seaboard and coalesces with the Atlantic coastal low in the Gulf of Maine and Nova Scotia late Sunday night and early Monday morning.
