I don't think it is possible for ANY forecaster to say it will definitely rain in Kidderminster or not! And it is certainly impossible for anyone to say there will or won't be storms, only what the likelihood is. The "Will it thunder?" feature on the homepage, if you have checked it, only showed a 35% chance of storms for Kidderminster for today. Therefore, there was a 65% that there wouldn't be any. Not really a high forecast for storms. :unsure:
Currently it shows as a 51% chance for Friday so the odds are, as it stands, slightly more in your favour.As far as here goes, it has been moderate to heavy showers on and off since early this afternoon so the forecast wasn't wrong.
