Shiz,
I think both of those posts give you an indication as to how poor weather watcher is. Its interpretation of UK weather data is based on what would be produced under those conditions in the US. As you can see there is a major difference.
Much of the same for the next few days I'm afraid. No sign or rain or snow or wind - lol
Frz rain refers to freezing rain, which is when rain freezes when it makes contact with the ground. A common and very dangerous occurance in winter.
If you are after weather information, you have 2 options. The first would be "live data" for current information, the second would be forecast data for future information.
<a href="http://www.tamworthweather.org.uk"><img src="http://www.tamworthweather.org.uk/images/advert.jpg"</a>
will give live weather data, sufficient for a 15 mile radius from Tamworth.
Alternatively, the MWF homepage has a plugin for you to input your location. This then gives weather data for your local area, as well as access to a live flood and national traffic data (direct from the agencies concerned).
