...Expect hazardous winter travel conditions from the Southern Plains to the Mid-Atlantic Coast, with significant snow and ice in the Southern Appalachians... A strong storm over the Central Gulf Coast will move eastward to the Southeast Coast by Sunday morning then move northeastward out over the Atlantic Ocean by Monday morning. The system will produce rain and snow over the northwestern edge of the precipitation shield over parts of the interior Southern Plains and Lower Mississippi Valley that will change over to areas of rain/freezing rain overnight Saturday over parts of the Tennessee and Southern Ohio Valleys. Also overnight Saturday, rain/freezing rain and snow will develop over parts of the Southern Appalachians/Southern Mid-Atlantic continuing through Monday morning. The snow will be heavy at times. Along the associated cold front, heavy rain will develop over parts of the Central Gulf Coast into parts of the Tennessee Valley overnight Saturday that will, likewise, move eastward to the Southeast Coast by Sunday morning then off the coast by Sunday afternoon. Showers and thunderstorms will develop over parts of Florida on Sunday morning, ending by overnight Sunday.
Accumulating snow from eastern New Mexico to Arkansas appears likely Friday into Saturday with snow totals of 3 to 6 inches, with locally higher amounts possible especially over the Texas Panhandle. South and east of the snow, a band of potentially hazardous freezing rain from roughly Lubbock, TX to Oklahoma City and into the Ozarks of northern Arkansas with accumulations in the .10 to .25 inch range is possible.
Snow will edge northward Saturday night, starting across the High Country of North Carolina then spreading across the entire area Sunday morning. Sunday morning the upper level low tracks over Tennessee and Kentucky increasing moisture transport over the wedge. The combination of upslope flow, strong warm air advection and isentropic lift will bring moderate to heavy snow to areas along and south of highway 460.

A Pacific system will bring gusty winds, moderate to heavy rain, and high elevation snow to California tonight which will shift to the southern California for Wednesday. This may cause travel impacts due to snow and debris flow flooding on recent burn scars. Higher elevation snow for the mountains of southern California and the Sierra Nevada range can also be expected, although accumulations should remain fairly light as a whole through much of Thursday.
The concern for tonight and Saturday will be severe weather and heavy rainfall which is expected to impact areas of the southern Plains, lower Mississippi Valley and Gulf Coast states as deepening low pressure near the Oklahoma and Texas panhandles ejects off to the east overnight and then toward the Midwest on Saturday. Widespread showers and thunderstorms will develop along and south of the front overnight.
A Great Lakes Cutter will enter the region late in the evening of December 1st, with precipitation mainly occurring as rain, with a few isolated ridgelines experiencing sleet. After that, the warm air pushes north, meaning that rain will occur throughout the entire region except the Presidential Range and Northern Maine. There is a possibility of backend snow as shortwave troughs rotate through.
A low-impact winter storm system will begin impacting the Northeast from Friday November 30th. This is a result of a fast-moving shortwave which should depart the region at around midnight on Saturday December 1st. Based off current modeling, it appears that any precipitation will not be long-lived nor have high rates, with QPF numbers being low across the board. The highest totals are expected in the Catskills, Poconos, Hudson Highlands, and the lower Taconics.
...Heavy precipitation is expected near northern California over the next few days with significant snowfall in the Sierra-Nevada into Friday morning... A series of storm systems will bring the threat for heavy rainfall over recent wildfire burn scar regions in California over the next couple of days. Excessive rainfall could lead to flash flooding, mud slides, rock, and debris flows. The potential exists for heavy snowfall, strong winds, and dangerous travel.
...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... 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.
