NWS email seeks to counter weather hype

I just got an excellent email message from Michael Lewis, warning coordination meteorologist, National Weather Service northern Indiana office. I’m excerpting it below, with his permission. Good words. Heed them!

NWS logo

As an NWS employee, I cannot police what people decide to ‘use’ for there forecast services; however, I would hope that our trained spotters would not fall victim to the hype and hysteria that is surrounding the model forecasts for next week.

The ‘hype-casting’ for an event next week is causing concern, when any well trained meteorologist will tell you that computer model skill beyond day 5 needs to be scrutinized carefully. Model solutions have been and continue to be “all over the place” and a simple change of 50 miles or change in speed of a few hours, changes to temperature and moisture and a host of other ‘artifacts’ can result in significant differences in the computer model generated output.  Here is a well written blog – http://www.gensiniwx.com/2013/12/the-truth-is-you-gave-lousy-forecast.html.  My sharing this link does not constitute the NWS opinion or support. This is shared because as a meteorologist, I agree with nearly EVERY point made.

The NWS in Northern Indiana is aware of the forecasts that are circulating, and we are providing forecasts based on our confidence in the solution.  It is still TOO early to say with any level of certainty or confidence what the system next week will produce, let alone whether it will be all rain, all snow, or for that matter WHEN it will begin and end. 

Please continue to monitor our websites and use our services to stay informed.

Quick Briefing Pages

I have been busy putting finishing touches on the Core Partner Briefing Pages.

    This continues to be expanded and new data and resources are being added on a weekly basis.  This is an invaluable tool for Situational awareness.

Don’t pay attention to long-range snowfall hype! Here’s why

A lot of amateur meteorologists are spreading a lot of hype about a huge snowstorm that’s supposedly going to hit next week sometime. As WANE-TV meteorologist Jesse Hawila wrote in a Facebook post yesterday, this is ridiculous. The same thing happened in December, when Twitter and Facebook users posted a map image from a forecast model run six and a half days in advance of the storm. That map (below) suggested that northeastern Indiana could get more than 20 inches of snow. But that didn’t happen!

European model snowfall map from Dec. 16, 2013
Forecast map from a European numerical forecast model created Dec. 16, 2013 for a Dec. 22-23 event.

Gensini

As that storm passed northern Illinois, DuPage College meteorology professor Victor Gensini wrote a great blog explaining why it’s so foolish to distribute images like the one above, especially without lots of explanation of what these computer models mean and don’t mean. Now that some people are again foolishly hyping the next big storm for our area, reading Gensini’s December blog is again worthwhile. Check it out. (Thanks to WANE-TV meteorologist Greg Shoup for sending a tweet about Gensini’s blog.)
