WeatherTalk monthly operating costs can top $2000.00.  Your $5 subscription helps pay for those costs.  I work for you.

The $5 will allow you to register up to seven phones!

For $5 a month you can receive the following.  You may choose to receive these via your WeatherTalk app or regular text messaging.

Severe weather app/text alerts from my keyboard to your app/cell phone.  These are hand typed messages from me to you.   During tornado outbreaks, you will receive numerous app/text messages telling you exactly where the tornado is located.

 

  • Daily forecast app/texts from my computer to your app/cell phone.
  • Social media links sent directly to your app/cell phone.  When I update the blog, videos, or Facebook you will receive the link.
  • AWARE emails.  These emails keep you well ahead of the storm. They give you several days of lead time before significant weather events.
  • Direct access to Beau via text and email.  Your very own personal meteorologist.  I work for you!

Typical progression on a severe weather day for subscribers.

 

 

 

 

I encourage subscribers to use the app vs regular text messaging.  We have found text messaging to be delayed during severe weather.  The app typically will receive the messages instantly.  I recommend people have three to four methods of receiving their severe weather information.

 

Remember, my app and text alerts are hand typed and not computer generated.  You are being given my personal attention during significant weather events.

 

 

WWW.WEATHERTALK.COM subscribers, here is my day to day schedule for your weather products.

 

These are bonus videos and maps for subscribers.  I bring these to you from the BAMwx team. I pay them to help with videos.

The Ohio and Missouri Valley videos cover most of our area. They do not have a specific Tennessee Valley forecast but may add one in the future.

The long-range video is technical. Over time, you can learn a lot about meteorology from the long range video. Just keep in mind, it is a bit more technical.

  1.  Increasing clouds today.
  2.  Light rain event tonight into Thursday night.  Widespread 0.10″ to 0.30″ with higher totals possible.
  3.  Slight chance of snow showers Sunday and Monday night.

 

We will have increasing clouds today as a storm system develops in Texas and moves northeast.

You can see the clouds already moving into the region on this mornings satellite imagery.

 

 

This will be a larger system as it pulls away from our region.

That means we will be in the beginning stages of the system.  Widespread light rain and rain showers will develop tonight and linger into early Friday.

This is not going to be a heavy rain event.  You can expect a widespread 0.10″ to 0.30″ event.  I did lower totals a bit.  There will be some patches of higher totals.  The most likely area for this to happen would be the eastern half of western Kentucky and into western Tennessee.

The rain may end as snow late Thursday night and Friday morning. Accumulations, if any would be light.

Some of the models show almost no rain at all.  That seems unlikely.  Low totals do appear likely.

Here is the NAM 3K model guidance future-cast radar animation.

Click to enlarge all the images on the WeatherTalk weather blog.

 

 

Let me show you a few of the model guidance packages.

Four models to show you today.  These are rain totals with tonight’s rain event into Friday morning.

Notice how the higher totals are skewed to the east.

There is not enough instability for lightning.  Severe weather is not a concern.

The pressure gradient will tighten up over the coming 72 hours.  A tight barometric pressure gradient means gusty winds.  The strongest winds will be Thursday night into Friday.  Winds should top 30 mph from time to time.  Loose Christmas decorations might be blown around.

Here is the NAM 3K wind gust forecast animation.  The strongest winds will be Thursday night and Friday.

 

 

 

 

Here is the Friday morning pressure gradient.  I drew in the isobars (equal lines of pressure).  Notice how tight they are.

 

 

Here is another animation of the system.  I pulled out a bit to show you the southeast United States.

Again, click image to enlarge it.

See how the system winds up to our southeast.  You can see a line of intense thunderstorms along what would be the cold front.

That line will remain well to our south and east.  No thunderstorm concerns here.

Keep scrolling down for the longer range outlook.

 

 

6 AM temperatures

 

 

 

 

 

The next two weather systems will be weak.  One arrives Sunday night and another arrives Monday night/Tuesday morning.

Both of these systems could produce light rain or light snow.  At this time, the chance of accumulating snow appears unlikely.  As always, monitor updates.

Some of the guidance packages do show slightly more organized precipitation.  I will be monitoring trends.  Occasionally, these types of systems do produce surprises.

The Canadian model is a bit more organized with the Monday night event.

Here is that model’s depiction at 12 AM Monday.  You can see light rain and snow in the region.  Green is rain.  Blue is snow.

 

 

Here is the 6 AM Monday depiction from the Canadian GEM model guidance.  You can see rain showers and snow showers in the region.

This model is the most organized of all models.

 

 

 

The Canadian model even shows accumulating snow Sunday night/Monday morning.

 

 

The GFS model shows no snow accumulation.  The ensemble data supports the GFS’s idea.

I will monitor trends, as always and update if need be.

 

 

The other models are showing a lighter event.  They show less in the way of rain/snow totals.  This appears to be a low-end precipitation event.

Let’s look at ensemble snow forecast totals.

 

The Canadian ensembles show no snow accumulation.

The GFS ensembles show little or snow accumulation.

 

I will monitor trends.

Another rainmaker arrives around Wednesday night/Thursday.

Green is rain.  Yellow is moderate rain.  Blue is snow.  Check out that heavy snow well to our north.

 

 

Here is yet another rainmaker around the 30th.

 

 

What about the so-called polar vortex that people are talking about?

There are some signals that a pool of colder air may move into the USA from Canada as we move into the first two weeks of January.  The confidence in this happening is not all that great.

Yes, it is possible.  The polar vortex is nothing new.  It happens from time to time.  It has happened since the dawn of man.

It is basically just a blast of cold arctic air that can produce well below normal temperatures.

For now, the overall temperature outlook for the coming days will be at or above normal.

That should continue into part of next week.

That means December will end overall with above normal temperatures.

Here is the six to ten-day outlook from NOAA.

This shows you the probability of above or below normal temperatures (when averaged together).

We are favored in the above normal temperature departments.

 

Here is the outlook for precipitation.  Again, odds strongly favor wetter than normal.

 

I will keep monitoring snow chances.  About your only hope right now is the Sunday night/Monday morning and Monday night events.  For now, those appear to be light.

 

 

I bring these to you from the BAMwx team. They are excellent long-range forecasters.

Remember, long-range outlooks are a bit of skill, understanding weather patterns, and luck combined. It is not an exact science.

We offer interactive local city live radars and regional radars. If a radar does not update then try another one. If a radar does not appear to be refreshing then hit Ctrl F5. You may also try restarting your browser.

The local city view radars also have clickable warnings.

During the winter months, you can track snow and ice by clicking the winterize button on the local city view interactive radars.

I encourage subscribers to use the app vs regular text messaging. We have found text messaging to be delayed during severe weather. The app typically will receive the messages instantly. I recommend people have three to four methods of receiving their severe weather information.

Remember, my app and text alerts are hand typed and not computer generated. You are being given personal attention during significant weather events.
