UK Weather: New week starts with a bang as forecast shows 5 days of rain. Many are hoping that the start of this new week might finally bring a change to the scorching and dry weather conditions that have occurred over the past month. The good news is that rain is on the forecast for the beginning of the week. Fresher conditions have now extended across the UK with plenty of showers developing across Scotland last weekend. Forecast models suggest that rather unsettled conditions will remain in the north over the next couple of days with rain or showers.
