Monday Evening Rambles…

1.)  Tuesday’s upper air disturbance looks to track further and further SW with each and every passing model run.  While we’ll keep an eye on things, it’s apparent that best snow chances will be across far SW counties, and even that may be generous (this thing is tracking much further west than what appeared a couple days ago), courtesy of NCEP.

42.)  A significant warm-up is still on schedule for late week, centered on Friday, where temperatures will likely push to, or exceed, 60 degrees as ridging builds in.  Image courtesy of Tropicaltidbits.com.

13.)  The warmth will be brief, however, as a colder pattern returns (thank you positive PNA), including an interesting look for winter storm potential across the east days 8-10.  (No need to get fancy with specifics at this juncture).

Series Of Upper Disturbances Bring Snow…

The relatively quiet and mild time of things this weekend will quickly give way to the promised return of winter next week.  An arctic cold front will sweep through the state late Sunday and set things in motion that will keep the weather feeling, and looking, very wintry around these parts over the upcoming week.

As we’ve discussed, models will struggle with handling the local impacts of multiple upper air disturbances that will race southeast in the fast northwest flow aloft.  We think Monday-Tuesday offer up the best chances of accumulating snow in the near term.  The upper energy will be able to maximize snow production around these parts and this looks like a 1″-3″ type event, with local amounts to 4″.  Winds will be quite gusty and blowing and drifting will be an issue, particularly in the open country.

Another vigorous disturbance will race southeast Thursday afternoon.  While the Canadian shows the bulk of the energy to our north, it would be close enough to ignite snow showers around here, as well.  Expect small changes with timing and track as we get closer.

Longer term, we also keep close eyes on next weekend.  The pattern is one that should promote a significant widespread winter storm.  The devil is in the details and we still have a ways to go, but the pattern set-up is one that screams an Ohio Valley winter storm threat from this distance.

Giddy up! 🙂
