    Across the far south, surface temperatures look to remain warm enough for just rain until sometime Saturday afternoon, when a change to snow will occur as colder air moves in. In the central part of the area, temperatures will be cold enough for freezing rain at times Friday night into Saturday, before changing to snow Saturday afternoon. Temperatures aloft and at the surface should remain low enough for just snow across the northern third or so of the area. Given this, the north could see 4 to 7 inches of snow, with central areas seeing 2-5 inches of snow with over 0.10 inch of ice. Windy conditions will develop Saturday afternoon and evening which could cause some blowing snow issues north.

    ... Major winter storm to impact the Northeast/Mid-Atlantic states into the weekend... The upper-level trough responsible for the ongoing storm over the western U.S. will generate a new surface low over the western High Plains by Friday morning. This system is expected to produce a vast area of heavy snow, heavy rain with pockets of freezing rain to the south-central states and much of the East Coast. Some thunderstorms will also be possible across the Gulf Coast region. Precipitation is progged to commence in the afternoon hours of Saturday 1/19, with heavy snowfall rates expected through the night hours in Pennsylvania and New York. However, in the urban corridor, a changeover to a wintry mix, freezing rain, or even plain rain is possible, particularly to the southeast. This is due to a warm nose infiltrating due to WAA. Freezing rain remains a pertinent threat, however any minor shifts in track can have major differences in impacted regions. For more information, check out your local WFO. Stay safe and know your forecast!

    A weak and broad area of low pressure will approach the East coast tonight along with some troughing aloft and shortwave energy. The energy in the southern branch of the jet stream is quite strung out and not all that impressive. The model consensus is for precipitation to start during the late evening, give or take a couple of hours from west to east. Not an impressive system with some of the BUFKIT profiles showing some gaps in the moisture, with the mid level forcing weak to say the least. Due to weak omega, in general snowfall amounts will not exceed two inches, and that may even be pushing it. Snowfall amounts on average should be around an inch, with very little for far southeastern sections, and up to about 2 inches in the hills in interior northwestern sections. POPs and QPF have backed down a bit with latest package, with QPF amounts generally around a tenth of an inch. With ground temperatures quite cold anything that falls should stick to most surfaces, even at the coast, at least to start.

    Blizzard warnings remain in effect for the highest elevations of the northern portions of the Sierras where snowfall amounts in excess of three feet expected. Winter Storm Warnings and Winter Weather Advisories are also in effect for the surrounding areas, as well as, Washington, the Great Basin, the Intermountain West and the Central/Southern Rockies. Coastal areas will have an increased risk for heavy rainfall and flash flooding-- especially along the stretch of coast from northern California to northwest Oregon and a small area in southern California.

    By Saturday evening, showers and thunderstorms should become more numerous across the Deep South as a warm front lifts northward from the Gulf of Mexico. Lighter snow amounts for the Mid-Atlantic and little snow for NC Saturday night and Sunday. However, with a strong surface wedge in place significant icing event for east from the crest of the southern Appalachians into the adjacent Piedmont is possible.

    ... Winter storm winding down through the Mid-Atlantic states as of Sunday night. The majority of the precipitation shield is across Maryland, the coastal regions of Virginia, as well as Delaware. Moderate to heavy snowfall rates are still possible as the storm captures some Atlantic moisture to work with, while at the same time moving further out to sea. The winter weather discussion from WPC has additional details on this system.

    The more significant facet to this storm system will be the winter weather impacts. On Friday, heavy snow is expected to occur along the Colorado Rockies and northern New Mexico. From Friday night into Saturday, widespread snow is forecast to effect areas from the central plains to the western portions of the Ohio Valley. The heaviest snowfall accumulations with this event are currently anticipated across northern Missouri and central Illinois

    A multiday storm is bearing down on the region. Currently, a small but intense band of snow is steadily progressing eastward. Numerous crashes have resulted in sluggish interstates across PA due to a rapid drop in pavement conditions. WWAs have been expanded into lower elevation terrain as a result of a colder-than-expected airmass sticking around the region. For southern areas, including SW CT and the NYC metropolis region.
