Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 331 AM EST Mon Nov 26 2018 Valid 12Z Mon Nov 26 2018 - 12Z Wed Nov 28 2018 ...Significant winter storm that impacted the Mississippi Valley to the Upper Great Lakes will come to an end today... ...Heavy rainfall to impact a small portion of the northern Mid-Atlantic... ...Heavy snowfall impacts parts of New England on this evening through Tuesday evening... ...Heavy precipitation returns to the Pacific Northwest by Monday... The winter storm that has dropped over a foot of snow across the Mississippi Valley northward into the Upper Great Lakes will begin winding down later this morning. As the upper level low and surface low slide eastward, snow and rain will taper off while increasing across the Lower Great Lakes and Ohio Valley. However, heavy snow will still continue through the early hours of Monday morning--with blizzard warnings still in effect through 6am local time from northeast Missouri northward into southeast Wisconsin/northeast Illinois, including the greater Chicago area. Winter storm warnings and winter weather advisories are also in effect from central Missouri northward into eastern Michigan; these warnings and advisories will also come to an end by this afternoon. For the latest on these warnings, see www.weather.gov. Meanwhile, the front associated with the surface low bringing snow to the Great Lakes/Mississippi Valley region will approach the eastern portions of the southeast states, Mid-Atlantic and Northeast today. Expect rainfall along and ahead of the front across the Mid-Atlantic southward to central Florida. Because of already saturated soils, there is a slight risk of flash flooding for a small portion of the northern Mid-Atlantic. The Storm Prediction Center also has portions of central Florida in a marginal risk for severe thunderstorms. Additionally, the Northeast will also get another round of showers and heavy snowfall particularly in the New England interior. The heaviest precipitation will move into the Northeast/New England area late tonight and into early Tuesday morning. By Tuesday afternoon, as the surface low begins to pull away, precipitation will begin to taper off but remnant snow in the New England interior will linger through Wednesday morning. Snow showers may continue on the backside of this system as well with generally light accumulations possible downwind of the Great Lakes and into the central Appalachians. After a dry weekend, moderate rainfall is moving into the Pacific Northwest early this morning. Rain and higher elevation snow will continue through Tuesday--stretching down into northern California and the northern Rockies. Snow and ice accumulations are expected in the Washington Cascades through midday today--where there are winter weather advisories in place. Furthermore, high winds will also impact the Northwest Interior of Washington with the strongest winds expected Monday night--with high wind warnings in place for this region. High elevation snow can also be expected for the northern Rockies along with the Sierra Nevada mountain range Tuesday afternoon through early Wednesday morning. The East Coast will continue to be slightly above average this afternoon as the central U.S. can expect high temperatures 15 to 30 degrees below average. By Tuesday, colder temperatures will move across the Northeast southward to central Florida, with high temperatures about 10 to 15 degrees below average. The central U.S. is expected to continue with high temperatures 30 degrees below average on Tuesday. Meanwhile, the western U.S. will be near or above average through Wednesday.
