Relief from the heat is arriving in Western Europe as temperatures return to seasonal norms, with significant rain expected in southern UK. This was reported by Qazaqyia.kz citing The Guardian.
Cooler weather on the way
After the fifth heatwave of the summer, cooler air masses are moving into Europe. From Monday, temperatures in Western Europe will begin to drop, with some areas falling up to 3°C below the seasonal norm. This represents a drop of more than 15°C compared with last Thursday.
Rain for the UK
A cold front from the Atlantic will reach southern UK on Monday night into Tuesday. According to the Met Office station at Wisley, Surrey, parts of southern England have had 62 consecutive days without rainfall. The last recorded rain on 16 June amounted to just 0.4mm.
From Wednesday into the weekend, low pressure will move across the UK, bringing frequent sharp showers and potentially thundery downpours. After such a prolonged dry spell, even a few substantial bursts of rain will make a noticeable difference to the environment.
Conditions in Europe
On Wednesday, the cold front will sink southwards into France and Germany, increasing wetness in continental Europe. However, rainfall in southern regions will be more hit and miss, relying on showers and thunderstorms, with the risk rising from Thursday.
Heat in the US
Across the Atlantic, southern US states have extended extreme heat warnings. Overnight lows are not falling much below 27-28°C, significantly higher than the UK's highest overnight minimum of about 22-23°C during the late June heatwave. High humidity and air temperature combine to produce apparent temperatures of 31-33°C overnight, with daytime heat index values potentially exceeding 46°C, especially across Louisiana and Mississippi. The National Weather Service warns of "dangerously hot conditions".
