Delta to spread heavy rain and thunderstorms across East Coast... ...There is a Slight Risk of excessive rainfall over the Southern/Central Appalachians and a Slight Risk of severe thunderstorms over parts of the Upper/Middle Mississippi Valley and parts of the Central Plains... ...Rain and high-elevation snow for Pacific Northwest and Northern Rockies... ...Elevated Fire Risk and above average temperatures across Great Plains... Post-Tropical Cyclone Delta is forecast to continue weaken slowly while moving into Tennessee Valley and the Central Appalachians/Mid-Atlantic. The storm is expected to produce rain and thunderstorms over the Southeast into the Mid-Atlantic, with the heaviest amounts falling in a swath over the Central Appalachians. The WPC has issued a Slight Risk excessive rainfall over parts of the Southern/Central Appalachians through Monday morning. The heavy rain associated with Delta will produce mainly localized areas of scattered flash flooding with urban areas, roads, and small streams being the most vulnerable. Isolated areas of significant flash flooding are possible. Post-T.C. Delta will become more extratropical while moving off the Northern Mid-Atlantic Coast on Tuesday. Meanwhile, front moving cross the Great Plains to the Lower Great Lakes to the Southern Plains will produce showers and thunderstorms over the Upper Midwest. The SPC has issued a Slight Risk of severe thunderstorms over parts of the Upper/Middle Mississippi Valley and parts of the Central Plains through Monday morning. The main hazards will be frequent lightning, tornadoes, severe thunderstorm wind gust, and hail mainly over that area through Monday morning. Another system moving into the Pacific Northwest will produce higher elevation snow and rain at lower elevations over parts of the Pacific Northwest into parts of the Northern Rockies through Monday evening. Temperatures across the Great Plains are expected to be well above average out ahead of a deepening upper level trough to the west. Highs could break records across much of the Southern Plains where temperatures could breach 100 degrees in a number of Texas cities. Very low dew points across the Front Range are expected to contribute to the Elevated Fire Risk for that area through Monday. A Critical area of Fire Risk is in effect for much of Western New Mexico and Eastern Texas as conditions there are likely to be very favorable for fires. Red Flag warnings are also in affect along the Central/Southern High Plains. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
