Different reported temperatures according to models

  • I'm not sure how to use windy.com yet. But what I'm primarily interested in is this: why are the reported temperatures (i.e., temps that occurred overnight) different according to the model used (e.g., NAM, Euro or GFS). Thanks for any reply. Btw: I love the graphics on this site.

    "Not all the models have the same data input and each model has a different mathematical way that the equations are solved. There are also differences in resolution, display of output and how physical processes are integrated into the model. " Jeff Haby

    So, different models give different outputs (temp., wind, rain etc)


  • I wish you would take the temperatures OFF....Thank You.


  • @meteo-gr I appreciate your reply. But I just got a better explanation on the Capital Weather Gang comments section in the Washington Post.

    Would you like to share the better explanation with us?


  • @meteo-gr Sure. A very bright guy named Eric explained to me---in language that I can understand---that I was probably looking at old forecast models that were created before the overnight hours began. That makes perfect sense to me.
    I should point that I'm an amateur weather buff that suffers from porphyria-induced neuropathy pain. The medication I take often makes my mind cloudy and my vision blurry. I would've responded to the first reply sooner (though Eric gave me his explanation yesterday) if I had known that the zoom feature on my Chrome browser was interfering with my ability to see your submit button.
    I can see it now; but only if it's at 110%. As soon as I go back to my normal number of 150%, it disappears.
    I still love looking at windy.com. The graphics are superb. And it's interesting to look at three different forecast models, among the various features of this weather web site.
