UK Weather: Warm Spells Ahead, But No Heatwave

Unsettled weather conditions, characterized by spells of rain and blustery winds, are expected across the UK in the coming week. This pattern is influenced by the jet stream positioning low-pressure systems over the country. However, a shift towards high pressure is anticipated later in September. This change may bring longer dry interludes and the possibility of daytime temperatures rising above average.

While some 'rather warm days' are possible towards the end of September, particularly in southern areas, the overall forecast suggests periods of warmth interspersed with cooler nights. The Met Office defines an official heatwave as three consecutive days hitting specific temperature thresholds, which vary by region. Current long-range forecasts do not indicate conditions will meet these criteria, and some mornings could be quite chilly.
