It’s a dismal start to the new workweek and August’s final day across Southern/Central England and Wales, courtesy of low pressure crossing from English Channel to North Sea. That system will be responsible for sliding the heat dominating much of mainland Europe through the course of this week.

Across Scotland and into Northern Ireland it’s a generally fine Monday with a few showers here and there. This IS a sign of things to come.

Through the first half of this week, we find ourselves squeezed between low pressure spinning near Denmark bringing cool, wet and windy conditions from Netherlands up to Denmark into Norway as well as East Coast Britain, while a strengthening high pressure system attempts to build into Ireland. However, it’s the hot dome over central Europe, bringing highs of 30-35C widely, that’s slowing the eastward upper ridge/trough from progressing east.

This setup of low to the east and high to the west means a brisk and cool northerly flow down the UK today through Wednesday but as we head into late week, that Atlantic high slides in over the UK by the weekend and looks set to stay put through much of next week.

Look for cool, breezy and showery days, cool nights, especially late in the week as clear skies combined with lighter winds heralds a rural frost threat.

Mainland Europe

As for the mainland, well after a hot weekend with further unseasonably warm numbers from Paris to Warsaw, the cold front associated with the low currently crossing Southern England today, will slide into France and across the Paris area, cutting the heat from the 30s this past weekend to upper 20s today down to the 18-21C range by tomorrow with heavy rain, gusty winds and storms.

We saw this fight and eruption of storms between a cool 16C London and 26C Paris at 9.30pm Saturday. When there’s that spread in temps, you know there’s a front in between.

This shot was captured around 9.30pm of storms over the English Channel.

The heat remains ahead of that front but through this week, the heat gets cut but as a result, major storms packing large gale, damaging wind, thunder and lightning and even the odd tornado cannot be ruled out.

By the weekend and into next week, expect temps average, possibly a little below average in the very areas currently back in the heat wave as a strong ridge builds into the UK.

Here’s the latest GFS chart showing the setup through the rest of this week on into next.

Check out the cool down in the below 2 metre temperature anomalies. The high building into the UK late week and weekend is a COOL one and so don’t expect a heatwave but pleasant sunny windless days and cool to even cold nights.

Hope to have a video for you by Wednesday.
