    Default Confirmation that the NWS forecasts are bogus



    I checked Weather Underground, Intellicast, NWS and all said that it would be raining and snowing tonight in my town. I got off of work at 10, had a nightcap and went home at 11 pm. No rain or snow, just a canopy of stars overhead with no clouds at all. I could just scream. How can I plan observing sessions with such lousy forecasts?

    Did you check the Clear Sky Chart for the location nearest you? I find those to be pretty accurate. At least around here.

    Ah yes..score one for Environment Canada and their seeing forecast. Seriously though, when I compare the forecasts of other sources to EC, I find that they are usually less accurate than EC's are. The great thing about the Clear Sky Chart is that the Canadian Meteorological Centre covers pretty much all of NA.

    But back to your original point, I truly hate when the forecast is exactly opposite of what was called for (and planned for )

    I like using Yahoo weather, they are always accurate. They also give the whole week forecast and the extended forecast for your exact location. Just go in there and type in your zip code.

    Weather.com is good too. They have an interactive radar map that you can view the cloud cover forecast for the next few hours. Really handy for planning an observing session. It is zip code/city specific as well. It has been very accurate in my zip code so far.

    Most people do not realize that all of the commercial weather sites such as Yahoo, weather underground and weather.com get their data from the NWS. I prefer to go directly to the source...

    I am not knocking the NWS, just complaining about how unpredictable this region of the USA is compared to Southern California. In SoCal most of the weather comes from the Pacific ocean to the west. In New England the weather can come from all directions.

    At least you had clear skies...I was looking forward all week to this past Saturday. Forecasts were consistently calling for clear to partly cloudy skies (including the clear sky clock that morning). Instead it was about 80% cloud covered (with horrible transparency in the holes). Sigh....

    One reason my little 102 mm SCT is my most used telescope .... makes it so easy to take advantage of the unexpected holes in the clouds.
