Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 AM EDT Fri Aug 23 2019 Valid 12Z Fri Aug 23 2019 - 12Z Sun Aug 25 2019 ...There is a slight risk of excessive rainfall over parts of the Central High Plains and Mid-Atlantic... ...There is a slight risk of severe thunderstorms over parts of the Southern/Central High Plains and the Mid-Atlantic... A cold front producing showers and thunderstorms will continue to slowly move off the Northeast Coast, while settling farther south over the Mid-Atlantic, Ohio Valley, Middle Mississippi Valley, and Central Great Plains on Friday. In addition to producing strong, gusty winds, some of these storms may produce heavy rainfall amounts, resulting in localized flash flooding. On Saturday, the front is forecast to settle farther south into the Southern Mid-Atlantic and Tennessee Valley, while lingering across Arkansas and Oklahoma back into the Central High Plains. Conditions will remain favorable for heavy rainfall amounts, particularly across southeastern Virginia and eastern North Carolina, where a series of upper level disturbances interacting with plenty of moisture may produce multiple storms, raising flash flooding concerns. North of the front, high pressure will continue to build across the Great Lakes and Upper Midwest, with much cooler temperatures spreading south and east from the the Great Plains and Midwest into the eastern U.S. late in the week through the weekend. Summertime conditions will continue ahead of the front across much of the Southeast to the Southern Great Plains. Showers and thunderstorms associated with trough of low pressure moving west from the Bahamas may produce locally heavy rains over portions of the southern Florida peninsula over Saturday or Sunday. The combination of low humidities and strong winds will lead to critical fire weather conditions for portions of the lower Colorado Basin, Central Great Basin and the Central Rockies. Red Flag Warnings are in effect Friday for portions of the region. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
