Clayton Stiver's First Call Snowfall Forecast for Saturday Storm
NH1 Chief Meteorologist - NH1.com
The forecast for Saturday is very much subject to change for NH, especially for southern reaches of the state to the Seacoast. Here is my latest thinking on the storm:
We will be on the western fringes of the swath of moisture from a low pressure system as it tracks up the coast Saturday. Because of this there will be a tight gradient between little or no snow and several inches of accumulation. For instance, Concord appears to be flirting with the 1" line right now. Go north and west of there and you may not see anything. Head south to Manchester though and we could pick up around 3" with maybe 4"-5" for Nashua and Portsmouth. A sweet spot of 5"-8" looks to be in Mass. near Boston and it's possible this zone could sneak its way up to the NH border, maybe even getting into Salem or Pelham. Any slight change in storm track could make for big differences in expected totals and snow coverage across the state so stay tuned.
Temperatures will be around if not just above 32 for this storm, so any snow that accumulates will be wet/slushy. Some rain could possibly mix with the snow, especially for the Seacoast.
Look for the activity to work across Southern NH and the Seacoast shortly after the noon hour Saturday. I think it wraps up by 10pm at night.
