As expected, our next winter storm Thursday is a mess both with forecast uncertainty & what falls from the sky. I've seen several atrocious maps floating around that were lazily created from a single model forecast, here's what to take away:
- A high impact winter storm is imminent Thursday for central & northern NH, particularly north of Concord. The majority of snow & sleet falls before the Thursday morning commute
- A band of heavy snow (1-2"/hour rates) is expected to set up across the Upper Valley & Lakes Region, though the exact north/south placement of this is still uncertain. Travel overnight under this band will become extremely hazardous.
- Warm air will punch in from the south, change snow to heavy sleet & freezing rain south of Concord, and drastically reduce snow totals. If this warm nose is very robust, this changeover likely occurs even further north into the Lakes Region.
- My snow forecast accounts for remaining uncertainty; a north/south shift of the warm front will have notable impacts for the Upper Merrimack Valley & Lakes Region.
- The majority of ski resorts will face issues with wind on Thursday as the approaching temperature inversion creates Bernoulli acceleration of low-level winds. Numerous lift holds and closures are possible.
