Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 351 PM EDT Fri Mar 29 2019 Valid 00Z Sat Mar 30 2019 - 00Z Mon Apr 01 2019 ...Cold front will spread precipitation across the eastern half of the country this weekend... ...Cooler temperatures will settle into the Central and Eastern U.S. behind the cold front... A low pressure system will continue to develop in the Plains tonight. Out ahead of the low, widespread rain and some thunderstorms are expected in the Midwest and Ohio River Valley through Saturday. Over an inch of rain and localized flash flooding will be possible in those areas. Back in the Central Plains, some severe thunderstorms will also be possible tonight, particularly from Oklahoma into eastern Kansas and Missouri. And behind the low, colder air will continue to support some accumulating snow in the Central High Plains and Central Rockies; the snow should taper off Saturday morning. Over the weekend, the low will continue to strengthen and push northeast, driving a cold front east toward the East Coast, and south toward the Gulf Coast. This will spread chances of rain over much of the eastern half of the country, and a changeover to snow -- with some accumulation possible -- is expected just behind the low over the Eastern Great Lakes and interior New England. Cooler air will settle in behind the front, especially over the Plains states on Saturday, and into the Eastern U.S. on Sunday. High temperatures should be 15-25 degrees below average just behind the front, and could struggle to reach 60 degrees over much of Texas, Oklahoma, Arkansas and Louisiana on Sunday. The Western U.S. will be under the influence of broad high pressure, which will allow temperatures to gradually warm with limited to no precipitation. By Sunday, the Pacific Coast should see high temperatures around 10 degrees above average. Lamers Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
