Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 340 PM EDT Mon Mar 25 2019 Valid 00Z Tue Mar 26 2019 - 00Z Thu Mar 28 2019 ...Showers and thunderstorms persist in the Southeast U.S. and rain/snow returns to the West Coast... ...Major river flooding continues across the Northern/Central Plains and Mississippi Valley... A low pressure system currently over the Ohio Valley will continue tracking eastward and produce showers and thunderstorms from the Gulf Coast to the Mid Atlantic this evening. Some storms could turn severe across parts of the Deep South today and tonight ahead of a cold front. The Storm Prediction Center has a slight risk of severe thunderstorms across parts of Alabama and Georgia. Showers will linger across the Southeast through Wednesday with most locations affected receiving under a half inch of rainfall, except for locally higher amounts where organized thunderstorm activity develops. Across the western U.S., a Pacific cold front is currently entering the West Coast and another is forecast to reach the region by Wednesday, advecting a plume of enhanced moisture across northern California and southern Oregon. Heavy snow is likely for the northern Sierra Nevada and the Siskiyou Mountains, and moderate rain for the valley locations and near the coast. Lighter precipitation is expected across northern Oregon and Washington, and extending inland across the northern Rockies. Mainly dry conditions are expected for most of the central U.S. through Wednesday evening. However, major river flooding and ice jams are still ongoing across much of the Northern/Central Plains and Mississippi Valley. This is due to temperatures above freezing and a melting snow pack. Numerous flood warnings and advisories are in effect. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
