Happy New Year everyone! The arctic door reopened early this week and so temps have been plummeting. Each morning, it’s gotten that bit colder further south as the near 1060 high migrated south. The core of the cold has been focused over the Rockies and Western Plains but this morning it’s reached all the way […]

The latest GFS 10mb temperature profile suggests a major event is ready to occur. By that I mean a sudden stratospheric warming as the model shows a complete 180 degree flip in the temperature profile over Greenland. The model takes apart the strong cold pool and develops a major warm pool where the core of the cold was within […]

It’s 2.15am and been on the road much of the day so will make tonight’s post rather brief. In a nutshell, arctic air is back in the Lower 48 as predicted and watch in the coming days as the cold pool expands and deepens. Within the next 24 hrs, the GFS sends a rare 1058 to […]

We know the cold is coming but did you know that snow may fall in Las Vegas New Years Eve or Day? There’s good model agreement that snow will reach the LV Valley floor in the coming days and may even see Vegas end December with more snow than New York City. A record 3.5″ […]

The stage looks set early next week with all in place for some extreme cold in the West that will eventually push south and east. Snowfall has continued to pile up over the Rockies and West from Christmas through today. GFS suggests 1-3ft of snow cover widely into early next week. GFS also continues to show […]

As your well aware, we’ve two things going on right now, 1) Dec 1-20 has been mild 2) arctic air is making a comeback. Some interesting notes, yesterday’s high of 65 degrees in Philadelphia was the city’s warmest Christmas Day in over 30 years while Detroit is on track to see it’s first December in 125 […]

Merry Christmas! It sure has been a mild Christmas for the East Coast with highs reaching 64 at Newark, 62 in Central Park, NYC which were both the 3rd warmest Christmas Day on record while it reached 59 all the way to Boston. 59 in Boston is 2nd warmest in the last 50 years. In contrast it’s been […]

Here comes the… polar vortex? What a turnaround and just look at those 7-DAY MEAN temperatures and departures. Dig this, there’s a rare BLIZZARD WARNING in effect for parts of Hawaii.

It finally got cold in Alaska, well normal for the time of year. On Friday, Fairbanks recorded it’s first sub-0 day which was the third latest in recorded history. Why? Blame or thank the persistent positive which lead to the warm Alaska/cold Lower 48 winter last year and the cold November just gone. The return of cold […]

The big Christmas storm is coming but it’s a question of how strong and where it’s exact track will be. As stated in yesterday#s post, this system will be noteworthy for 3 aspects, 1) wind 2) flooding rainfall 3) surprise southern snow making for a White Christmas in areas which don’t typically see snow at Christmas. Latest […]
