Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 PM EDT Fri Apr 03 2020 Valid 00Z Sat Apr 04 2020 - 00Z Mon Apr 06 2020 ...Severe weather and flash flooding possible in Texas through tonight... ...Active weather for the West will lead to heavy snow in the Sierra Nevada through the weekend... Rain and thunderstorms are expected for Texas through the weekend, but particularly tonight into Saturday as a cold front slowly moves across the state. Locally heavy rain causing flash flooding as well as severe weather, especially potentially large hail in southern Texas, are possible. There are Slight Risks in place for both the severe and flash flooding hazards through Saturday morning. Farther north, the strong cold front will continue moving eastward across the Upper Midwest, bringing some light additional snow and freezing rain totals behind it, but the bulk of the winter weather has finished in the north-central tier. Colder than normal temperatures are likely for the central U.S. again on Saturday, but the cold front should weaken considerably by Sunday as it loses upper-level support. A couple of potent upper-level lows approaching the West Coast will bring precipitation to the Pacific Northwest, California, and into the Great Basin through the weekend. Rain is expected for lower elevations with snow for higher elevations. Snowfall amounts will be largest in the Sierra Nevada and Shastas, with over a foot or two of snow forecast there. Rain should begin in Southern California Sunday, and there is a possibility of localized flooding there particularly over burn scars. Colder than average temperatures are also expected in the West. The large Atlantic low pressure system is forecast to move eastward tonight into Saturday. This evening and tonight, showers could continue over the Northeast, along with windy conditions and the potential for coastal flooding in the Mid-Atlantic region. These conditions should end early Saturday as the low moves farther offshore. Tate Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
