Potential Arrival of Heatwave in the UK After Passing of Storm Floris?
The remnants of ex-Tropical Storm Dexter, currently located in the western Atlantic near Bermuda, have impacted the UK weather forecast for August 2021, drawing warm air from the southwest and leading to a marked temperature increase.
The warm air flow from the southwest has caused an uptick in temperatures across the UK, particularly in central, southern, and eastern England. This weather phenomenon has resulted in a predicted heat spell, with highs topping 30°C in some areas.
Steven Keates, the Deputy Chief Meteorologist at the Met Office, has noted the confidence in rising temperatures linked to ex-Dexter, but has indicated uncertainty about the duration of the heat. The continuation of hot weather depends on other atmospheric patterns beyond Dexter’s influence.
Ex-Tropical Storm Dexter has also brought some patchy rain and drizzle mostly to western and northwestern parts of the UK.
Looking ahead, forecasts indicate the possibility of warmer and drier weather returning in August, particularly affecting the southern and eastern regions of England. Weather models suggest there could be further intervals of heat in August, with temperatures in mainland Europe reaching the mid-30s Celsius. Some areas in the south of the UK could potentially exceed 30 degrees Celsius.
However, some rain may still occur, particularly in the northern and western parts of the UK. High pressure is expected to bring drier conditions across much of the UK, especially compared to the previous weeks. There is potential for temperatures to climb into the high 20s Celsius due to the influence of Tropical Storm Dexter.
The exact path of Tropical Storm Dexter will influence how long the anticipated warmth will last and how close certain areas will reach heatwave thresholds.
Recently, parts of the UK experienced a shift towards cooler and wetter conditions following a series of early summer heatwaves. On Monday, Storm Floris arrived in the UK, bringing a taste of autumn with unusually strong winds in the northern UK, resulting in drought-like conditions, leading to the implementation of hosepipe bans and the occurrence of wildfires.
In summary, ex-Tropical Storm Dexter acted as a catalyst for a warm spell in the UK during early August 2021, notably raising temperatures and modifying weather patterns primarily in southern regions, with some localized rain in the west and northwest. The average temperatures for the UK in August are expected to be above normal, consistent with the broader trends associated with climate warming and prevailing weather forecasts.
The weather patterns in the UK experiencing a significant change due to the influence of ex-Tropical Storm Dexter, with a heat spell predicted, particularly in the southern and eastern regions. This shift could be linked to the rising concerns about climate change, as science suggests that such extreme weather events may become more frequent and intense in the future, potentially impacting the environmental science of the UK.
