NWS:

It very much remains the case that the upcoming short to med-range winter pattern from the weekend into early next week will be especially impactful for a broad swath of the central to eastern U.S.. An upper trough in the central U.S. Sunday will produce a consolidating surface low in the Southern Plains. Precipitation is expected to push across the eastern half of the U.S. with this low and good dynamical support aloft. Cold air in place will favor widespread heavy snow that will be heavy across areas from the Central Plains, Mid-Mississippi Valley, and Ohio Valley Sunday. Snow will push into the Mid-Atlantic Sunday night into Monday. Just to the south, there is a relatively broad transitional area that will see impactful mixed precipitation types, transitioning between multiple p-types and/or seeing snow and sleet/freezing rain. Potentially significant sleet and freezing rain are possible across the Ozarks east to the Tennessee Valley and south-central Appalachians/Mid- Atlantic. WPC is issuing Key Messages for this winter storm. Meanwhile farther south in the warm sector, expect lingering trailing frontal showers and thunderstorms to spread eastward into and across the Southeast into Monday.

Colder than normal temperatures are likely across the central and eastern U.S. underneath rounds of upper troughing and with cold surface high pressure systems. Notable cold is possible in the northern tier, with even high temperatures barely reaching 0F and lows between -10F and -20F in some areas. This should not be record breaking, but the cold could still be hazardous as wind chill values may dip below -20F to -30F. Temperature anomalies of 10-20 degrees are also likely across parts of the northern/central Plains to Middle Mississippi and Ohio Valleys to Appalachians into much of next week, especially if areas are snow covered and hold temperatures down. Meanwhile, initial upper ridging in the western U.S. will allow for slightly above normal temperatures in the Intermountain West, and 10-20 degrees above normal anomalies in the south-central U.S. Sunday will cool to below normal behind a cold front by Monday. The upper pattern in the West is uncertain by midweek next week, causing temperatures to be in question, but there may be a trend toward warming for parts of the West.

hoping the snow is fluffy and fine instead of wet and heavy. it is already pretty cold for most of us and isn't expected to get above freezing before then, so it seems possible, and the sleet and ice line at the southern edge of the storm is predicted to be relatively narrow, but still very worried about all the people and pets sheltering outside a heated building.
