Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 236 AM EST Fri Nov 22 2019 Valid 12Z Fri Nov 22 2019 - 12Z Sun Nov 24 2019 ...Light snow and freezing rain possible from the Central Plains to the Northeast... ...Locally heavy rain to move across the Tennessee Valley and Mid-Atlantic through the weekend... The main weather system to impact the contiguous United States through Sunday morning will be a cold front and developing wave of low pressure across the Eastern U.S. For today, light rain will traverse across the Northeast and Mid-Atlantic, with light snow found across Maine and the interior Northeast. Light snow will also be found further west across the Central Plains underneath an upper-level low. Meanwhile, light to moderate rain will impact the Lower Mississippi Valley as a low pressure system begins to strengthen along the cold front. By Saturday, this low pressure system will enter the Tennessee Valley and bring locally heavy rain from northern Alabama to the central Appalachians. As the system tracks eastward and off the Mid-Atlantic coast by Sunday morning, rain will spread into southern New England. Light snow and freezing rain will be possible across the northern periphery of the precipitation shield from the Ohio Valley to the Northeast. Elsewhere, the southwestern U.S. will see temperatures rebound after several days of active weather. In fact, above average temperatures will encompass nearly the entire western half of the United States ahead of the next weather system, which is forecast to enter the Pacific Northwest on Sunday.
