Good Wednesday to one and all. 2019 is off and running on a rather gloomy note with… Wait for it… Wait for it… More rain rolling in. This rain comes in a couple of waves with the first impacting the south and east today and the next one areawide by Friday.
Where the heck is winter? As you know, my winter forecast was heavily weighted on winter arriving for the second half of the season. I’ll get to all that in a bit.
Let’s start with today’s rain rolling into parts of the state. This mainly impacts the south and east, but a few showers can’t be ruled out across the rest of the region. Here’s your regional radar to track whatever shows up:
Thursday will find just a shower chance across the region as our next system gets ready to roll in. This is the system the models had well off the southeastern seaboard up until a few days ago. Now? It’s so far west that it’s another rain maker for our region…
That system misses it’s connecting flight and just cannot get any cold air into it.
Once that goes by, temps turn mild for the weekend, before a greater change develops. That change means we actually slow down the southern storm brigade, leading to the northern branch to throw some systems our way…
That’s more of a back and forth pattern setting up next week, but those initial changes of slowing down the southern storm track are important and a sign of bigger changes ahead.
For the past few weeks, a lot of folks have been asking me about a Sudden Stratospheric Warming over the North Pole. This generally spits the Polar Vortex and sends it toward lower latitudes across the Northern Hemisphere. Much of that talk was based on model forecasts that were still a ways away from happening, so I didn’t even comment on it. Plus, the impact of such a split of the Polar Vortex isn’t even felt until a few weeks or so after it happens.
Well, that’s now upon us and Dr. Judah Cohen has the illustration…
Happy #PolarVortex split day! This is looking like the split that keeps on giving, long lived event with three distinct daughter vortices meandering across the mid-latitudes. If you are a #winter weather enthusiast I can’t think of a better way to kick off 2019. pic.twitter.com/KaCdMfb7QF

If we look at the new European Weeklies from WeatherBell, we see the type of pattern you would expect from that. Here’s a 7 day temperature anomaly later this month…
7 day temp anomaly as we end January and head into early February…
And into the middle of February…
The snowfall from through this same time period…
This goes along with the seasonal analogs that I’ve talked about over the past few months. All are skewed toward the second half of winter. Plus, aren’t most of our winters of the past decade been late bloomers? 3 of the past 4 winters have featured historic snowstorms after January. Even the winter of 13/14 didn’t get kicking until the middle of January then didn’t stop until late March. Same thing with 08/09 and 09/10. The only winter that kicked butt early was 10/11. 12/13 was just a “meh” winter that was normal-ish. The only horrible non-winters were 11/12 and 16/17.
Remember, seasonal forecasting is a marathon and not a spring. Everyone wants instant gratification, but the weather just does not work that way, especially in wintertime. 🙂
I will have updates later today, so check back. Make it a great Wednesday and take care.
Did you mean sprint.
Anyway, thanks for educated me and the public about long distance forecasting.
Did you mean educating?
It was an informative article. Thanks for your hard work, Chris!
Chris you should have ended it with, “So all you wining weenies out there just wait and give winter a chance.”
Happy New Year to Chris and everyone else out in the KWC world. Looking forward to seeing what old man winter has in store for us later this month into Feb/March.
Really don’t think anyone is whining..When the potential is there to lose most of Jan. to milder weather makes you wonder about winter as a whole..Have little opportunity in our parts to get snow so losing a prime month is not good..There are signs that the pacific will eventually become favorable but everything wants to keep getting pushed back farther in time,which is another warning shot..Still believe we’ll have a good winter but holding out judgement for Jan. until models have better agreement which I think we should know in a few days.
Yeah I guess no one is making wine on here!! Just seems some people have already written off winter. IMO we are just getting started. I like the indecies and analogs that are showing up. I trust NO model more than 48 hrs out and the NAM is the best to follow at game time.
By the end of Feb there may just be saying they haven’t experienced a winter like this since 77/78. That’s if you were around then.
Think Snow! And give winter a chance is what I say.
I understand everything in this post, but I also understand that the long range models had shown cold and snow for December and January, is this correct? What makes it different?
Bengalfan, we just got to take it one a day a time to see how things pans out. I thought the same way that you mention. Then again we may get more than what we ask for. But only mother nature knows.
Agree! Winterlover…
Of course we take it one day at a time, but I was talking about the models and predictions. As bubba said, it has been predicted, but keeps getting pushed back and back…maybe, it will change,
I agree, winter is coming in a couple more weeks has been the theme for the past month…..
This is correct. Since the outlooks were wrong for then, it would not build too much confidence for the current outlooks. CB’s point though seems it is more a broad range of time, rather than specific months. I am not a big snow fan anymore, so if little snow, not a biggie for me. The rain though needs to stop for a few weeks! I am whining about that!
^^THIS^^
You can spell to. 🙂
I just want it to dry out a little. Not had a good winter as far as snow is concerned since the late 90s down here in Knox County. Always get too big a window of mixed precipitation that cuts the totals way down. Just looking for a few dry weeks to dry the ground up a little.
The models only show around an inch of rain in SE KY for next 3 days but we have to watch that NW trend as the heavier totals are projected not far south of us. Only a couple of inches within 24 hours would cause problems now as we have had almost 2 inches already this week on top of wet ground!
The river is as full as its been in a while in Knox County.
I agree. My yard has been a swamp most of 2018. I can’t use my yard due to swampy conditions and I live on a slope. It just is slow to drain due to so much water. Tired of having to wipe down the dog every time he comes in.
I don’t mind winter showing up, but NO TO THE POLAR VORTEX haha
???? Haha
