Thunderstorms on Monday before becoming very hot next week

The prospect of very warm to hot weather next week is still on the cards, and remains the most likely forecast option next week. A continued Atlantic influence through this weekend and into Monday will bring more mixed conditions, with some showers likely by Monday. These showers could merge into longer spells of rain or thunderstorms later on Sunday / especially Monday, with central and western parts favored for downpours, giving the risk of localized flooding. These thunderstorms and downpours will be hit and miss, but those who catch them will know about it.

The Met Office have a warning in force for Sunday and into Monday, which covers large parts of England and Wales. Isolated thundery downpours, especially in the west may develop, note: these may continue into Tuesday to.

As we progress into the remainder of the week strong south easterly winds are set to increase temperatures drastically. There is still a significant amount of doubt with regards to just how warm / hot it will get. The most likely outcome at present is that large parts of the country will see temperatures in the mid to upper 20s Celsius, with the south eastern portion of England seeing temperatures into the low 30’s (31-32C). Peaking on Wednesday or Thursday, the heat wont necessarily last all that long.




Monday will most likely be the first notably warmer day, with temperatures rising into the upper 20’s Celsius for south eastern parts, though some showers will continue. Cool temperatures will persist in the north east. A continued risk of thunderstorms in the west on Monday, which will keep temperatures a bit cooler compared to the south east, where it will be drier and consequently warmer.

The warmth becomes more widespread on Tuesday, perhaps reaching 30C in central London. Much of England and Wales will become increasingly warm with temperatures comfortably into the 20’s by this point. Again a further risk of thunderstorms, especially for western areas, hot sunshine likely for central and eastern parts. Overnight temperatures will also be warmer than average, making sleeping difficult in the south. The north will remain cool, especially in Scotland.




By Wednesday the heat will become more widespread, with temperatures in Western Scotland and Ireland into the 20’s. Strong easterly winds by this point means that north sea facing coasts (east coast) will lack in temperature compared to further in land. This temperature difference may be enough to induce instability and thunderstorms. Again muggy and uncomfortable overnight.

Highs by Wednesday:

There’s a lot of uncertainty about the forecast the remainder of the week. Temperatures will most likely remain above average, however a strong easterly wind will most likely offset the heat on the east coast, and this effect may cool down much of the east, depending on the strength of the wind. Throughout next week there is a risk of thunderstorms, early on in the week in the west, and by mid week central and eastern areas could see some disruptive thunderstorms, a lot to stay tuned to.
