I have been using the weather.com website for years and, at this time of year, they always start off by predicting a high chance of rain in the afternoon which, quite often, drops away dramatically

For example, at 3pm this afternoon (2pm in brackets) they showed the following chance of rain:

5pm - 41% (76%)
6pm - 71% (98%)
7pm - 79% (98%)
8pm - 71% (68%)

so, in the space of an hour, their prediction for rain at 6pm and 7pm dropped from a confident "almost certain" 98% to considerably less.

To put it another way, their prediction of "no rain" at 6pm has soared from 2% to 29%!

I know weather forecasting is an inaccurate science, but they can see what's coming from hundreds of miles away so why can't they be a little more accurate for what's going to happen in just a few hours?

Their percentages for rain do this almost every day - go on-line in the morning and they will predict a very high chance of rain, yet a few hours later it will most likely have plummeted

It's almost as if they start off with exactly the same figures every day, ignoring all of their instruments, then crank them down as time goes on, just to give themselves something to do

Anyway, what sites do you use for weather in the next 24 hours?

Thank you

Answer is simple.

98% chance generates more hits than 76% chance.
