This is a map showing the most likely effects of the winter storm which will arrive in the triangle late Saturday night/early morning Sunday. I've broken it up into 5 distinct zones. I've mainly been concentrating on the triangle region, so pay less attention the the details further west in the state.

Zone 1: 1-3 inches of snow possible at the onset changing to sleet and rain by late morning. Minimal impacts expected.

Zone 2: 2-4 inches of snow/sleet possible at onset. changing to freezing rain/sleet at around lunch. Possibly changing to rain by late afternoon. .5 inch ice accrual possible. Significant winter weather impacts expected. The southern and western parts of this region are not part of the winter storm watch right now, but I think has a good chance to be added to the eventual winter storm warning.

Zone 3: 4-9 inches of snow mixing with sleet and freezing rain. Then back to snow.

Zone 4: 8-12 inches of snow possibly mixing with sleet and freezing rain..

Zone 5: Over 1 foot of snow possible, possibly mixing with sleet.

For the triangle expect a better chance for winter weather impacts on the Northwest part of the triangle near Chapel Hill with less impacts in southeast Wake.
