    The GFS model and the European model were pretty much the same.

    This is from my work meteorologist for NC/SC
    Weather Discussion Weather-related outages are not expected across the Carolinas Service Area through Saturday. A major winter storm will arrive from the west Saturday night through Sunday bringing accumulating snow, sleet and freezing rain to the region. Heavy snow is expected across the mountains and foothills and possibly even the Triad area. Across the Piedmont, a period of snow will be followed by significant icing (sleet and/or freezing rain) then possibly a change back to snow as the event winds down. Locations near and east of I-95 will have a period of wintry mix followed by a changeover to rain.

    Major power outages are expected across the region Sunday into Sunday night.

    An upper-level disturbance will approach the area from the northwest today and cross the region tonight. Considerable cloudiness is expected across the region with the possibility of snow showers across the higher elevations this afternoon. Weak pressure builds across the region through Saturday. Skies will be sunny on Friday but then considerable cloudiness returns on Saturday with much colder afternoon temperatures.

    A storm system will develop over the Plains on Friday and rapidly strengthen over the Lower Mississippi Valley on Saturday, then cross the Southeast on Sunday as a major winter storm. While the models are in fairly good agreement overall, there are some minor differences that result in significant differences in the overall impact. The first difference is the timing of precipitation onset. The American model brings precipitation into southwestern NC and Upstate SC on Saturday evening whereas the European model is about 6h slower with precipitation not arriving in these areas until after midnight. There appears to be more model guidance favoring the slower timing, so will lean in that direction. Also, the European model has a slightly farther south/southeast track over the low pressure center, which is also better aligned with other model guidance. The track will determine where the snow/mix line sets up and which locations in the “wintry mix” zone get sleet vs. freezing rain.

    Similar to yesterday’s thinking, locations northwest of I-85 are expected to receive significant snowfall with this event. The mountains can expect 12”+ of snow accumulation while the foothills can expect 6-12” of snow accumulation, with significant snow accumulations also possible across far northwestern portions of Upstate SC as well as western portions of the Triad area. In the vicinity of the I-85 corridor and eastward toward the I-95 corridor, there will likely be a period of snow followed by a prolonged period of significant icing. What remains unknown at this time is whether this will be sleet (i.e., ice pellets) or freezing rain (i.e., raindrops freezing on contact). The potential exists for widespread 0.25-0.40” ice accumulation across the Piedmont. If much of this precipitation falls as freezing rain, then major power outages will occur as the freezing rain will accumulate on trees and power lines. However, if much of this precipitation falls as sleet, the impacts will be much lower with the main concern being hazardous roadways. Locations near and east of I-95 will have a period of wintry mix followed by a changeover to rain with minimal impacts. The precipitation will wind down on Sunday evening.

    Temperatures will be very cold on Sunday. For Carolinas-West, the current forecast calls for readings to be nearly steady in the middle 20s through the morning and early afternoon then slowly rise toward 30 degrees by early evening, then be nearly steady around 30 degrees on Sunday night. For Carolinas-East, temperatures will be in the upper 20s in the morning and lower 30s in the afternoon, then warming to the lower 40s in the evening before dropping back into the 30s overnight.

    My zip code is 8-13 on weather.com. Accuweather says 3-6 with .1" ice. NOAA hasn't published yet. Local idiots saying 10-20". At least we're not guessing our asses off or anything.......you'd think they have the equivalent of a magic 8 ball for snow totals.

    4 to 8 inches again for Middle TN starting Saturday but mainly Sunday. I'm sure that won't be a disaster again.

    Latest from work for NC/SC

    A major winter storm will arrive from the west Saturday night through Sunday bringing accumulating snow, sleet and freezing rain to the region. Heavy snow is expected across the mountains and foothills and possibly even the Triad area. Across the Piedmont, a period of snow will be followed by significant icing (sleet and/or freezing rain) then possibly a change back to a period of light snow as the event winds down.

    Locations near and east of I-95 will have a period of wintry mix followed by a changeover to rain with minimal impacts. Major power outages are expected across the region Sunday into Sunday night.

    The storm system will develop over the Plains today and rapidly strengthen over the Lower Mississippi Valley on Saturday, then cross the Southeast on Sunday as a major winter storm. Precipitation will spread into the western Carolinas before daybreak on Sunday morning, then heavy precipitation is expected on Sunday morning through Sunday afternoon before winding down late afternoon and early evening. The main uncertainty with this storm continues to be exactly where the heaviest ice accumulations occur.

    Latest model guidance suggests slightly lower ice amounts across eastern NC but then slightly higher amounts across north-central NC. At this time, the greatest ice accumulations are forecast to occur along and southeast of the I-85 corridor from the Greenville-Spartanburg area to the Charlotte and then northward toward I-40.

    Locations northwest of I-85 are expected to receive significant snowfall with this event. The mountains can expect 12”+ of snow accumulation while the foothills can expect 6-12” of snow accumulation, with significant snow accumulations also possible across far northwestern portions of Upstate SC as well as western portions of the Triad area. In the vicinity of the I-85 corridor and eastward toward the I-95 corridor, there will likely be a period of snow followed by a prolonged period of significant icing. What remains unknown at this time is whether this will be sleet (i.e., ice pellets) or freezing rain (i.e., raindrops freezing on contact). The potential exists for widespread 0.25-0.50” ice accumulation across the Piedmont, especially near and to the southeast of the Charlotte Metro Area. If much of this precipitation falls as freezing rain, then major power outages will occur as the freezing rain will accumulate on trees and power lines. However, if much of this precipitation falls as sleet, the impacts will be much lower with the main concern being hazardous roadways. Locations near and east of I-95 will have a period of wintry mix followed by a changeover to rain with minimal impacts. The precipitation will wind down on Sunday evening.

    Temperatures will be very cold on Sunday. For Carolinas-West, the current forecast calls for readings to be nearly steady in the middle 20s through the morning and early afternoon then slowly rise toward 30 degrees by early evening, then be nearly steady around 30 degrees on Sunday night. For Carolinas-East, temperatures will be in the upper 20s in the morning and lower 30s in the afternoon, then warming to the lower 40s in the evening before dropping back into the 30s overnight.

    • The sugar beet is of course used to make table sugar as well as feed for cattle.
    • The product we use is a by product of the process that makes the sugar for our tables. It is a result of a fermentation process that extracts the sugar crystals leaving the juice behind.
    • Beet juice has been proven to lessen the corrosive properties of the salt that we use to apply to the roads.
    • Beet juice cost are relative the same as calcium at $1.70-$1.85 per gallon.
    • We use a mixture of 80% salt brine and 20% beet juice in most areas.
    • Beet juice and salt brine will work at temps approaching zero but with the addition of calcium we can theoretically achieve a little lower temperature before freezing occurs.
    • We store around 30,000 gallons of beet juice/brine mix to be used at a moment’s notice.
    • The beet juice actually needs salt brine to melt ice.
    • At 30 degrees, one pound of salt will melt 46.3 pounds of ice, but at 0 degrees, the same pound of salt will melt just 3.7 pounds of ice.
    • Regular water-based salt brine works well until 25 degrees.
    • Beet juice is added to the mix between 25 degrees and 5 degrees.
    • Calcium chloride added to the mix between 5 degrees and -10 degrees.
