Monday January 10 2022
The good news this morning is that the wind did its job. Roads dried out before the temps tanked below freezing. Early reports had main travel in good shape. There was a lot of concern for work and school travel. Then again, some schools have gone virtual again because of Covid. That part is beyond the scope of my weather focus.
The other side of this story is that arctic air is settling in for a few days. Winds will make this afternoon feel really cold! But tomorrow will actually be colder, as the winds calm.
While the rest of the week looks cold, this weekend a coastal storm will try to develop. At this time it looks like a miss, but worth watch (long range guidance has not been reliable).

Afternoon Wind Chills
Jet Stream: Vorticity
The leading edge of arctic air will arrive late afternoon. This may come with some extra clouds and a flurry. Behind it, winds actually turn calm with the core of the coldest air arriving.

I have often said the long range models are not reliable with surface storms. However, the upper air pattern is still good guidance for trends. Here we see a key factor: Reinforcing cold air from the arctic. I see progressive winter pattern that will establish itself for the eastern US.
Even farther out there is more support for storms. I will address that in my report later today.
All the talk of a storm, now appears to be a near miss. The models hav diverged, and taking that potential system just out of reach.
I am NOT discounting it yet. However, it is worth monitoring while keeping expectations at a minimum for now.
A weak system that might bring flurries or light snow Saturday night… Then pushed off the coast. This model actually performed best over the last 10 days.
A stronger system but just out of reach…
This model has a longer history of accuracy, until this past week.
7 Day Forecast
Next weekend: Do not change plans, just know there may be something nearby that I will tend to all week simply for any trends. I still do not value any legit storm forecast until within a 5 day window.
