Clayton Stiver's Latest Snowfall Forecast for the Winter Storm Saturday
NH1 Chief Meteorologist - NH1.com
My latest thinking on the storm for Saturday for the Granite State. Over the last 24 hours the computer models have made a slight shift to the north and west with the swath of snow. As mentioned before, one slight shift could make for differences in expected snowfall totals, and that is the case here compared to my map from last night. For instance, Concord, I think you now fall in the 3"-5" zone as opposed to the 1"-3" zone from last night. The Lakes Region was looking at little or no snow yesterday, but now it seems we're talking 1"-3" here, maybe even a little more for southern reaches of the Lakes. For Manchester, you now sit on the 5" line with points south and east of there in a zone of 5"-7".
Look for light snow to overspread the area from south to north between 8am and 10am with snow becoming moderate to possibly heavy working through the afternoon (moderate to heavy mainly for Concord and points south and east). The snow looks to be done for all by 9pm.
Temperatures will be running around 32, so this will be a wet, slushy snow accumulation. Be mindful of slick roads. Some isolated power outages are possible, certainly at the Seacoast where we could see some wind gusts up to 30mph, but at this time I think we'd need to see higher totals than what is forecast to get widespread power outages.
Overall, this will be a quick moving storm and I do not anticipate this to be blockbuster or record breaking. Having said that, it will still make for plowable conditions especially for southern parts of NH and the Seacoast. Stay safe everyone.
