Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 308 AM EDT Sat Jun 24 2017 Valid 12Z Sat Jun 24 2017 - 12Z Mon Jun 26 2017 ...Post-Tropical Cyclone Cindy will move quickly northeastward along the Northeast U.S. coastline today... ...Heavy rain and flash flooding possible from portions of the Gulf Coast states to the Southeast, as well as portions of the Southwest... ...Well above average temperatures expected to continue for much of the western U.S... Post-Tropical Cyclone Cindy is moving quickly east-northeastward across the Mid-Atlantic region early this morning, and the system is expected to continue to accelerate northeastward today while gradually becoming absorbed in a surface frontal system by late afternoon. The combination of Cindy and the frontal boundary will bring showers and thunderstorms to much of the Northeast this morning, with most areas beginning to dry out during the afternoon as the front moves offshore. Farther south, the cold front will produce numerous showers and thunderstorms today across portions of the Gulf Coast states and the Southeast, with the tail end of the front producing showers and storms across portions of the Southwest. These showers and storms could produce heavy rain, and flash flooding is possible. The front will make slow southward progress by Sunday, with areas of showers and thunderstorms persisting along the immediate Gulf Coast as well as across extreme eastern portions of Georgia and the Carolinas. Across the West, high pressure at the mid and upper-levels will hold strong through the weekend, with generally dry conditions and above average temperatures expected. The most anomalous temperatures will be across the Pacific Northwest where highs are forecast to be 15 to 25 degrees above average today and Sunday. Some locations in the Northwest away from the coast are forecast to surpass 100 degrees. Temperatures will also remain above average in the Southwest. While not the record heat of recent days, high temperatures in that region are expected to be 5 to 15 degrees above average. Ryan Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
