A potential heatwave looms on the horizon for the UK after the passing of Storm Floris.
The UK weather in August 2021 was marked by a series of shifts, with the influence of Ex-Tropical Storm Dexter playing a significant role.
As conditions evolved, the jet stream moved closer to the UK, allowing low-pressure systems to impact the weather. Dexter, located in the western Atlantic near Bermuda, lost its tropical characteristics and transformed into a low-pressure system. This system potentially reshaped future weather patterns for the UK, particularly in the southern and eastern regions.
The northward position of the jet stream during the first half of the summer led to drought-like conditions, resulting in the implementation of hosepipe bans and the occurrence of wildfires. However, Dexter's presence may have contributed to somewhat cooler, wetter weather compared to typical summer conditions in those areas.
Despite Dexter's influence, the anticipated change in weather patterns suggested high pressure bringing drier conditions across much of the UK, especially compared to the previous weeks. Weather models also suggested there could be further intervals of heat in August, with temperatures in mainland Europe reaching the mid-30s Celsius. Warm spells were predicted to emerge particularly in the southern and eastern regions of England.
Dexter may have helped form a ridge of high pressure over the UK this weekend, potentially leading to warmer temperatures, particularly in the southern and eastern regions. However, some rain may still occur, particularly in the northern and western parts.
The average temperatures for the UK in August were expected to be above normal, consistent with the broader trends associated with climate warming and prevailing weather forecasts. Storm Floris arrived in the UK on Monday, bringing a taste of autumn with cooler temperatures. It is too early to accurately predict which days will be the warmest, but temperatures could climb into the high 20s Celsius due to the anticipated high pressure.
In summary, Ex-Tropical Storm Dexter's influence on the southern and eastern UK in August 2021 would predict unsettled weather with rain and cooler temperatures relative to a typical warm, dry August. This aligns with the general behavior of ex-tropical systems affecting British weather. However, the average temperatures for August were expected to be above normal, consistent with climate warming trends.
- The impact of Ex-Tropical Storm Dexter might have influenced the weather patterns in August 2021, particularly in the southern and eastern regions of the UK, shifting them towards cooler, potentially wetter conditions compared to typical summer conditions, as environmental science suggests that ex-tropical systems can bring changes to the climate.
- While the presence of Dexter may have contributed to somewhat cooler, wetter weather in August 2021, the science of climate change predicts that overall average temperatures for the UK in August would be above normal, aligning with broader trends associated with climate warming.
