Hull’s thunderstorm forecast this week as heatwave comes to an end

Heavy and thundery rain could arrive in Hull and East Yorkshire on Thursday morning, according to the Met Office.

The forecaster issued a yellow-level alert on Sunday warning of potentially “intense” thunderstorms over a 36-hour period between 6pm on Wednesday and 6am on Friday.

Torrential rain, hail, frequent lightning and strong gusty winds are all possible in areas where the worst of the weather hits.

The Met Office’s current rainfall radar forecaster suggests our region is most likely to see any storms between 5am and noon on Thursday, though there remains uncertainty regarding the location and timing.

In the latest forecast, Met Office meteorologist Alex Deakin said: “We’re looking to the south as some potentially very hot and humid air comes up and these weather fronts could spark some significant thunderstorms later this week. Quite a bit of uncertainty about the exact timing and, of course with thunderstorms, the exact location.”

The stormy weather could bring a risk of “travel disruption and flooding” in the East Yorkshire area, according to forecasters.

A Met Office spokesperson said: “Although there remains significant uncertainty in location and timing, areas of thunderstorms are expected to move northeast across parts of England and Wales from late Wednesday through to Friday morning.

“Whilst not all locations will be affected, some intense thunderstorms may occur during this period with torrential rain, hail, frequent lightning and strong gusty winds possible.

“Rainfall totals of around 30 mm could fall in an hour, with some locations potentially receiving around 50 mm in 2-3 hours, although these will be fairly isolated.”

Experts have issued the following warnings as part of their alert but it should be noted there is only a “small chance” of the below happening:

  • There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail and strong winds
  • Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
  • Spray and sudden flooding could lead to difficult driving conditions and some road closures
  • There is a small chance that some communities become cut off by flooded roads
  • There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost

Despite the thunderstorms, temperatures should remain between 19C and 25C this week.

Looking ahead to next week, a Met Office spokesperson added: “It is likely to be warm, perhaps very warm and humid towards the southeast at first with the risk of thundery showers across southeastern areas.

“Elsewhere sunny spells and fresher conditions, with some rain and thicker cloud towards the north and west at times.

“The fresher air is then likely to gradually spread to the rest of the country bringing a change to widely cooler more changeable conditions towards the end of the week, with a low risk of warm and humid air returning to the far southeast at times.

“This will likely bring occasional spells of rain or showers interspersed with drier and sunnier conditions. Overall, temperatures will likely average out to be close to normal.”
