New weather charts have pinpointed the exact date and locations where warmer conditions will return to the United Kingdom, following a brief interruption after the recent heatwave that saw temperatures soar to 26C in parts of the country earlier this week. The forecast indicates a temporary cooler period before a sharp rebound in temperatures, offering a detailed outlook for the coming days.
Cooler Snap to Briefly Interrupt Warm Spell
According to maps from WXCharts, a cooler airmass is set to sweep across the UK from Wednesday, April 15, bringing a noticeable drop in maximum temperatures. For most regions, temperatures will sink to between 10C and 13C, with the South and South-east experiencing slightly milder conditions at 14C to 17C. However, Scotland and northern England will feel the chill more keenly, with highs plummeting to just 7C to 11C during this period.
Warm Weather Rebound from April 20
Fortunately, this cooler interlude is expected to be short-lived. Forecasts show that by Sunday, April 20, temperatures will begin to pick up again across the country. Weather maps reveal that southern England, including London and the South East, could see temperatures climb to 17C to 19C, while the Midlands and Wales are forecast to reach around 14C to 17C. Further north, temperatures will remain more subdued, ranging from 9C to 12C.
The warm air is projected to continue into Tuesday, April 21, with much of southern England experiencing highs of 18C to 20C. Central areas are expected to reach 16C to 18C, while northern England and Scotland will lag slightly behind at 10C to 13C. This pattern aligns with broader pressure charts for mid-April, which indicate cooler air dominating around April 15 before milder conditions push back in from the South.
Met Office Long-Range Forecast
The Met Office long-range forecast supports this shift, predicting mixed conditions that show signs of improvement later in the month. From April 15 to April 24, conditions are expected to be changeable at first, with low pressure bringing showers or longer spells of rain, particularly in the North-west, alongside some strong winds.
Meanwhile, the South-east is likely to stay drier and brighter. Later in the period, the weather may turn more settled, especially in northern areas, though parts of the South could still experience rain at times. Overall, temperatures are anticipated to be near or slightly above average, reinforcing the signal from weather maps that any mid-month cool spell will be temporary, with milder spring conditions quickly returning.
This forecast provides a clear timeline for Britons anticipating the return of warmer weather, highlighting the transient nature of the upcoming cooler snap and the swift rebound expected as April progresses.
