    The NAO moving up a bit and getting picked up by the model.

    Lets see what the EURO and ENS have. As I have said before, models have chaos trying to figure out the NAO for what it's effects are downstream.

    Big changes over Alaska on the last few runs of the Euro, in addition to more ridging over Greenland.

    How cold has the first half of December been....well here in Chester County PA with 132 years of climate data this December is the 11th coldest start to the final month of the year. Below are the 20 coldest first halfs of December. While we will moderate a bit to near or slightly above normal for the remainder of this month we will still end December with below normal temperatures and finish the 2025 calendar year with 7 of the 12 months averaging below normal temperatures.

    26-30 some models are showing a sw that wants to sneak under a Hudson Bay hp. To be met by a -nao and 50/50. Obviously the next time period to watch.

    Think there is enough evidence for a High Wind Warning for Long Island.
