Temperatures will soar to 30C in parts of northern Lincolnshire today, but thunderstorms look set to break the heatwave that follows.
Weather forecasters say inland areas could see temperatures as high as 30 degrees Celsius, although temperatures could be cooler in the coastal regions, with peaks of 27-28 degrees Celsius in Cleethorpes and a little light due to sea breeze. However, unsettled weather is ongoing, with a yellow storm warning in place for the area.
Coastal areas are also more likely to avoid thunderstorms, which are expected to hit land between 3pm and 6pm. According to Met Office forecasts, Scunthorpe and Immingham both have the ability to see thunder, but Grimsby and Cleethorpes are able to escape.
It’s warm and sunny today, with temperatures already well below 20 degrees as people wake up from an uncomfortably wet night’s sleep. The sun will set all morning, the thermometer hits 30 degrees Celsius at 1 pm.
Things are set to change dramatically later. Light rain and showers will move to northern Lincolnshire by mid-afternoon, with a chance of storms to follow.
The Met Office said: “Thunderstorms developing across northern England and Scotland could cause disruption and local flooding on Sunday afternoon and evening.”
The yellow thunderstorm warning implies a small chance of quickly flooding homes and businesses, which could cause damage from floodwaters, lightning strikes, large hail or strong winds. There is also a small chance of a power cut.
Met Office chief meteorologist Matthew Lehnert said: “The UK weather this weekend features some stark contrasts, with some potentially damaging thunderstorms developing affecting the northern half of the UK on Sunday, while further south it will get hotter.
“For those in the north, there is a chance of thunderstorms as we see a change to cooler conditions with the possibility that these conditions could become organized with heavy rain, hail , lightning and gusty winds.”
Next week is likely to be cooler and more unsettled, with frequent showers and temperatures in the high teens or low 20s. Monday is set to start off nice and bright, but showers could develop from mid-morning, though there will also be plenty of sunshine. It will peak around 21 degrees Celsius in Grimsby and 20 degrees Celsius in Scunthorpe.
