Britain is preparing for a warm spell this weekend, with temperatures potentially reaching 22C in several regions, including the West Midlands and Staffordshire. Forecasts indicate that eight areas may experience highs of 21C or more, significantly above April's average daytime maximum of 14C. According to WXCharts, southern regions will be the warmest, while Wales and Scotland will see temperatures ranging from 11C to 20C. The Deputy Chief Forecaster, Steven Keates, noted that high pressure will keep conditions mostly dry and sunny, although some areas may experience cloud cover and patchy rain, particularly in northern Scotland. Additionally, tree pollen levels are expected to be high, which could exacerbate symptoms for the 16 million hay fever sufferers in the UK. Those affected are advised to take precautions against pollen exposure, such as wearing sunglasses and applying Vaseline around the nostrils. Overall, the warm weather is expected to continue into the weekend, with potential overnight frost in some areas.
