THE LAMBS OF DECEMBER....

December 3, 2019

CONSIDER THE VALUE PLEASE...TSwails.com continues to be a leader in catching and forecasting the trends of our extreme weather pattern the past few weeks. It takes a great deal of commitment, passion, and knowledge to stay on top of the swings. Now that I'm no longer in television, this is my job and that's the reason I'm asking for a voluntary subscription fee of $12 dollars a year, one dollar a month to keep TSwails going. Together we can create one of the best, most unique, and reliable weather sites in the Midwest. Your contribution of 3 cents a day, allows me to stay free of the corporate world and pour my energy into doing what I do best, forecasting the weather! We hope you see the value and hard work that goes into the site everyday. Your support in any way is sincerely appreciated. Thanks and roll weather. To donate click on the secure green box below.

TUESDAY'S FEATURE POST:

 

December got off to a lousy start around the Midwest with plenty of crummy weather from wind, to rain, and snow...especially to the north. The heavy snow up that way really brought the seasonal totals to impressive levels going into the 2nd day of December. Most of Minnesota and Wisconsin have had 12 to 30 inches plus. While my area hasn't seen much the last 3 weeks, we too are still 6-10" above normal.

These were snow depths reported Monday morning. It's plenty white in the northland!

This satellite image clearly shows the snow line just out of my local area.

From the looks of things, there won't be much of any precipitation (rain or snow) the next 7 days. The lambs of December will be with us into the coming weekend. The EURO ensembles have this for total precipitation through Sunday. Zip, nada, none!

This is snowfall for the same period. Zip, nada, none!

Beyond the 10 day period things get side-tracked, especially with regard to the GFS solution. It brings a powerful Arctic front across the Midwest December 10th with some eye popping cold and wind chills.

The 5 day temperature departures on the GFS ensembles are frosty December 11-16.

The operational GFS is even colder for the same period. 

The EURO was not having any of that earlier today with a morning run that looked like this for departures December 11-16th.

The night run (0Z) was quite different. I don't have it far enough out to show the 5 day departures but the one day anomaly for December 12th is a good indicator this is a much colder run!

The Climate Prediction Center is riding a different train and showing this. That looks way off base.

As you can see we have an important trend towards colder weather in the long range if the models hold. About 9 days ago the GFS did a similar thing and I took a chance on it based on some favorable teleconnections for cold. I had to back off a few days later as the model flipped. Now it's trying to go cold again and so is the EURO. With a tendency to be warm biased, this is a big change in direction for the EURO. It certainly lends confidence to a colder weather pattern around December 10th.

 

Meantime, watch out for the sheep of December, they are roaming the countryside bringing peaceful weather and goodwill to all, at least through the weekend. Roll weather...TS

 

SANTA CALLING! Christmas is less than a month away. Are you looking for something special for that hard to buy for person? Maybe you just want to treat yourself for being on the nice list! Well, here's an idea that can "give" any weather enthusiast a lifetime of pleasure. It's called WEATHER SCHOOL. What a person experiences and learns here will open up the world of forecasting for years of enjoyment to come. Consider giving the gift of weather. Better hurry, only 12 desks still open. You can get all the details below.

TSwails.com is offering a very special and unique opportunity to learn first-hand the ins and outs of weather forecasting with one of the best meteorologists in the Midwest along with his team of expert meteorologists.

 

That’s right… You want to forecast right along with Terry Swails, well now you can. He’s teaching weather with TSwails newest program called WEATHER SCHOOL. The opening bell rings this January and you can be a member of the very first graduating class. The one-day forecasting seminar for weather enthusiasts will be held at his home in January. It’s not your typical run-of-the-mill school. There will be no tests, but Terry, Rebecca, and Nick will cram your head with so much knowledge, it’ll be spinning like a tornado before the day is over.

 

You want to know the essential online sites to use for models, radar, and the basic weather tools? DONE! You want to understand the structure of models and the role they play? DONE! You want to be able to construct forecasts from the ground up? DONE!

 

WEATHER SCHOOL will be presented in a seminar-type format where you'll have the ability to ask questions and dig deep. You’ll get the scoop on data acquisition, model analysis, severe weather, and actual forecasting from the big dog himself, T. Swails. With 43 years of experience and an uncanny ability to break the science down, you’ll open the door to forecasting like never before.

 

Along with the head master T. Swails himself, meteorologists Rebecca Kopelman and Nick Stewart of KGAN TV will be there to lend their knowledge and experience to the discussion. It will be fun, informative, and factual! This is the day for you to see, feel, and experience what it’s like to be in the hot seat of a meteorologist.

The seminar will be held January 25th and will last from noon until 5:00pm. We have limited seating and the cost is $99 dollars per person. A catered lunch will be provided. Again..not a lot of seats so reservations with a pre-payment are required. Sorry, no refunds. If there’s enough interest, a second session will be added in early February. To register or get additional information send an email to carolynswettstone@yahoo.com

 

GIVE THE GIFT OF WEATHER. This might be the perfect gift for that hard to buy for person this Christmas. Along with a WEATHER SCHOOL admittance voucher, TSwails will send a special holiday greeting to your weather enthusiast if you give the gift of weather with the TSwails touch!
