Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 356 PM EDT Fri Apr 29 2016 Valid 00Z Sat Apr 30 2016 - 00Z Mon May 02 2016 ...Severe thunderstorms possible across parts of the Southern Plains into parts of the Lower and Middle Mississippi Valley through Sunday morning... ...Heavy rain possible over parts of Eastern Texas, the Lower Mississippi Valley, Western Tennessee Valley and West Virginia... ...Snow over parts of the Central Rockies and Central High Plains... Scattered to widespread showers and thunderstorms continue to impact portions of the Southern and Central Plains, Lower and Middle Mississippi Valley and western Tennessee Valley. Strong to severe storms are dumping excessive rainfall as they move through the area. A few locations already have ongoing flooding, however the risk across the entire region will remain elevated through the weekend as the frontal system tracks eastward. Meanwhile, upper-level energy over the Great Lakes will move eastward off the Northern Mid-Atlantic Coast by Saturday morning, producing rain from the Great Lakes to the Northern Mid-Atlantic and Southern New England by early Saturday morning before ending. On the cold side of the system, primarily Central Rockies and the adjacent plains, rain and snow is occurring. Numerous winter storm warning and advisories are in effect for the Rockies in north-central New Mexico and Colorado, southeast Wyoming and the western half of Nebraska. Snow will persist over parts of the High Plains into Saturday and through the weekend across portions of Colorado. Total snow accumulations from this system will vary greatly at lower elevations - 1 to 6 inches will be common. Isolated areas in southwest Colorado, southeast Wyoming and the Nebraska panhandle could range from 8 to 18 inches by Monday evening. A cold front plunging through California and Great Basin is bringing additional rain and highest elevation snow over parts of the Northern Intermountain Region and the Northern Rockies today. As the system continues to move south through the Southwest and Southern Rockies, rain with embedded thunderstorms will develop over the Great Basin and Southern Rockies and expand northward into the Central/Northern Rockies by Saturday evening.
