it's a gimmick now, mostly for gardeners and travel.  They should rename it to The Recreational Channel.

 

Makes sense-there's so many other sources for weather now.   They had a monopoly from 1980-2000

and they are owned by IBM a corporate tyrant, who also bought WeatherUnderground and started charging people large sums of money to upload data from PWS.

I wonder how many watch TWC now vs 30 yrs ago--has got to be 1/5 of what is used to be....

TWC was my childhood. I was a kid in its heyday. Honestly I probably credit it partially with my intense passion for earth science.

Me too.   I remember hearing about a channel that was about to be launched that was all weather all the time.  I could hardly contain myself!    I literally knew the lineup and when to tune in-5 day planner at .20, tropical update at .50 etc.

It was between TWC and AM Weather on PBS/Ch21 here.  Before I had cable, I used to watch AM Weather during the 90s.

Am Weather sounds familiar, but can't remember a thing about it?  Comcast in Union County NJ removed the full time weather/radar about 10 years ago.  Maybe with everyone owning a smart phone, it was no longer really necessary?

Is that what is was called? Was that on in the early 80s too? I remember watching some early morning weather show not on a major network. My first distinct memories of this are from April 1982.

Yep, and they gave flight info and it's the first time I ever heard of these terms!  It was only on for 15 minutes a day in the 80s and 90s at 7:15 AM but I loved watching it and I remember looking at their forecast snow maps-- they were usually first onto a potential threat before the local news stations got it.

Found it!

It was on until 1995-- ended just before the historic 1995-96 snowfall season (but at least it was here for 1993-94 when I remember watching it almost every morning!)

 

https://en.wikipedia.org/wiki/A.M._Weather

A.M. Weather^[1] was an American weather news program that ran from October 30, 1978 to February 3, 1995. and was broadcast on PBS member stations throughout the United States. The 15-minute daily program, which aired fifteen minutes before or after the hour (depending on the station's scheduling of the program) and was produced by Maryland Public Television (MPT, or before 1984 the Maryland Center for Public Broadcasting), featured detailed forecasts presented by meteorologists from the National Oceanic and Atmospheric Administration (NOAA).

While many other media outlets embraced computer weather maps and graphics in the 1980s for weather forecasting use, A.M. Weather held back on fully embracing computer graphics until 1991, although the program did adapt to such graphics for satellite and radar maps in the late 1980s. The show's trademark yellow pointer was a mainstay of the program entire run.

Overview[edit]

The show's progression usually started with a satellite and radar segment, followed by the current conditions around the U.S. (vice versa in early years), then the forecast (especially in terms of temperatures and precipitation), followed by an aviation forecast (locations of MVFR and IFR, aircraft icing, turbulence and winds aloft) and ended (when necessary) with an inclement weather report, called "WeatherWatch" (the only time that the yellow pointer was not used).

The program aired its final edition on February 3, 1995; one of the reasons behind A.M. Weather's cancellation was that MPT wanted to expand on its morning business news enterprise with Bloomberg L.P.

Hosts included NOAA meteorologists Carl Weiss, Joan von Ahn and Wayne Winston, as well as H. Michael Mogil, Rich Warren, Dale Bryan and Barry Richwein. Other notable substitute hosts included: Regis Walter, Steve Zubrick (now the president of the National Weather Association), Gary Petti (a meteorologist with National Weather Service and National Environmental Satellite, Data, and Information Service (NESDIS), now retired), and George Lessens (now the chief meteorologist at WZZM in Grand Rapids, Michigan).

WeatherBell Analytics was predicting 30 inches, and Joe Bastardi, the former long-range forecaster at AccuWeather, saw temperatures slightly below normal, “and the worry is it will be colder.” Not to worry: It was one of the milder winters on record.

Record cold and snow was coming for 6 months in a row according to him. His 57-58, 65-66, 76-77, 77-78, 02-03 and 09-10 “analogs” and “migrating Modoki” worked out superbly lol First it was Thanksgiving week/late November, then Christmas week, then late December/New Year’s, then late January and early February, then mid-late February “Sixteen Chapel” cold and snow pattern, then early March, then March 10th-April 10th, then late March/early April, “coldest and snowiest start to spring in history”. Anyone who actually takes him seriously anymore needs a psychiatric evaluation

1. When was the last time in advance of winter that he said the “worry” is it will be warmer than his forecast in the E US?

2. He mentions his energy clients often. Energy companies typically do better when winter is cold in the E US. I think this reinforces his natural cold bias in winter.

3. There was no major SSW in Dec like he thought might occur though there were a couple Jan-Mar.

4. He hardly ever recognizes the cold bias that has prevailed for years with the seasonal models.

5. I’m predicting he’ll once again not go warm for his FINAL winter forecast 2024-5. He’s already been showing strong hints about this. One thing he’s already harping on is suggesting a +PDO next winter based on what are clearly to me faulty Weatherbell CFS SSTa map progs for late in 2024 as I’ve shown, including not showing the E/SE of Japan marine heatwave and instead showing cold in a good portion of the W/C Pac. This is despite TT maps from the same CFS as well as from other models showing -PDO continuing.

6. There isn’t even a single winter when for the bulk of the E US he went warm at least since 2014-5 (I don’t mean just slightly AN) and stayed that way. There was one recently (2020-1) that he started off pretty warm (~+3) and cooled it considerably to NN for his final forecast. His frost covered glasses wouldn’t let him go warm and stay that way:

Prelim DJF 20-1

Final DJF 20-21:

 

 One thing I will give him kudos for was recognizing the importance of the concept of RONI vs just using ONI due to the very warm SSTs elsewhere that were dominating even though it didn’t help his fcast:

“There is little cold water anywhere, so the difference in temperatures (relative SSTs) is nowhere near the standard El Niño”

Any reason why seasonal models have a cold bias?

 I‘m talking mainly E US, esp in winter. It isn’t just seasonal. The major MR models as a whole have been too cold much more often than too warm for years. That’s likely why, for example, that there’s more often than not a NW correction of surface lows as we get closer in forecast time. When they have the lows too far SE, they usually prog it to be too cold in the E US. Then they come NW in later runs to match the warmer reality.
 
 I suspect it is due to the very warm WPAC that @bluewaveoften mentions. This often causes the atmosphere to act like the MJO is in the MC even when it isn’t. This very warm WPAC has according to a pro met I’ve talked to helped to enhance the “SE ridge” (similar to what the MJO MC phases do), something the models usually underestimate for some reason. If the MR models are too cold, there’s no reason to expect the seasonals to not be similar.

He isn’t just going for a cold and snowy east coast winter this year, he’s going epic (95-96, 10-11). I can see it coming already. That’s why he’s wishcasting a huge Atlantic hurricane season with recurves and super high ACE, 95-96 (-NAO) and a +PDO. He knows that even if the +PDO doesn’t work out, he can just fall back on 10-11 being -PDO/+QBO, and still use 95-96 if his tropical Atlantic wishcast works out

While it’s a bit early for me to start thinking about next winter, the winter warmth since the 15-16 super El Niño has been simply astounding. There had never been a sustained 9 winter period in our modern instrumental period back to the late 1800s this warm before in the Eastern US. My guess is that the shift is related to dramatic warming in Western Pacific which began back in 2014. This is in concert with more frequent and higher amplitude MJO 4-7 phases. Even with the El Niño this winter the Aleutians ridge near the Dateline was unusually strong. This has been a repeating theme since 15-16. It also works to amplify the ridge and warmth in the East.

All the seasonal model winter forecasts since 15-16  have been significantly too cold. This is probably related to the models not having the capability to factor in the historic SST changes since 2014 in the Pacific when they have been making their seasonal forecasts. So it will be interesting to see if this pattern keeps repeating in coming winters or something happens to shift away from this persistent 9 winter pattern.

The fundamental result of this study is that the first EOF of SST in the North Pacific has changed starting in 2014. For more than 20 years, the PDO has been used to describe the state of the North Pacific. However, since the marine heatwave of 2014, there have been remarkable changes to the dominant mode of SST in the North Pacific. The spatial pattern of the first EOF of SST from 1950 to 2021 is notably different from the PDO, suggesting that though the PDO served as a useful metric of SST variations until 2014 (Johnstone & Mantua, 2014), it may no longer be as effective a climate index for the North Pacific. From 1950 until the 2014 MHW, the first EOF remained consistent in its proportion of positive and negative regions with both taking up roughly half the area of the North Pacific (and with the positive region taken to be the eastern Pacific). When EOFs are calculated from 1950 to endpoints after 2014, the first EOF has a maximum positive region covering 77% of the North Pacific, with a PC indicating the largest anomalies on record. These changes to the first EOF/PC of North Pacific SST are nothing short of remarkable.

In concert with these changes, the second EOF/PC of SST has also undergone profound evolution since 2014. This second EOF now accounts for approximately 18% of the variability, growing from 13% during the 1950–2013 period. The spatial structure of the second EOF now is positive over almost the entire basin, with a PC that has grown strongly positive in the last several years. Thus, the second EOF/PC describes warming over much of the Pacific not in the positive lobe of the first EOF.

We’ll probably need better climate models in the future to give us that answer. 
 

https://www.nature.com/articles/s41612-022-00301-2

This work must be open to the idea that climate models, as currently formulated, may be deficient in their representations of past and future changes in tropical Pacific climate. Until this issue is resolved, many aspects of future projections that are strongly influenced by the tropical Pacific – including future regional climate, teleconnected climate risks, and the oceanic uptake of CO2 – will be highly uncertain.
