Who on earth supplies the data for the Thai Visa weather report?

For today for my location moderate weather (mostly no rain) was prognosed. As a matter of fact it down-poured with small breaks from about 11 in the morning to 5 in the afternoon. This was not a thunderstorm that often hits only very locally but a low front passing through- and as such it was predictable; the television weather report did predict it. Interestingly enough: the CURRENT WEATHER CONDITIONS were desribed for 16.00 hours as CLEARLY SKY--- a lot of nonsense, there was no clear sky today at any time. So, again, who manufactures???? these data? Are there more reliable local weatherforcasts around on the web? Cheerio Stefan

I find this one more accurate, but still not perfect.
