Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 348 PM EDT Thu Mar 14 2019 Valid 00Z Fri Mar 15 2019 - 00Z Sun Mar 17 2019 ...Severe weather is the main remaining threat associated with the strong low pressure system... ...Blowing snow and strong winds lingering in the Plains in the low's wake through Thursday evening... ...Colder than average temperatures in the western/central U.S. will move into the East on Saturday... The strong low pressure system that has caused widespread snows, high winds, and thunderstorms continues to move northeastward into the Upper Great Lakes region, and will move into Canada on Thursday night. As it exits the U.S., snow will wind down, but blowing snow is expected to continue this evening in portions of the Plains. High winds will remain possible in the Plains, Mississippi Valley, and Ohio/Tennessee Valleys, and High Wind Warnings and Wind Advisories are in effect. Along and east of the cold front, widespread thunderstorms are likely. The Storm Prediction Center has outlooked an Enhanced Risk of severe weather through Thursday night, with tornadoes possible in the Ohio/Tennessee Valleys. Isolated flash flooding from heavy rain is possible as well. Showers and thunderstorms will push into the Eastern Seaboard on Friday, but widespread severe weather and flash flooding are not likely. Additional upper-level energy is expected to move through the Great Lakes region on Friday and Saturday, creating more chances for rain and snow showers. Snowfall accumulations should be light, generally 1 to 3 inches. Rain showers will remain along the Gulf Coast through the end of the week. The Eastern Seaboard will have a warm Friday ahead of the cold front--many locations will break their record high minimum temperature records on Friday morning, and high temperatures will be in the 70s as far north as the Mid-Atlantic. That will change on Saturday, however, once the cold front passes and high temperatures in most of the eastern U.S. switch to below average. Most of the western/central U.S. will remain below average temperature-wise through the end of the week, with the Southern High Plains seeing high temperatures 15 to 25 degrees below normal. The Pacific Northwest is forecast to see slightly above average temperatures, however. Tate Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
