Updated Information from the Met Office Advisor - Hot Weather, Thunderstorms and a MEDIUM Impacts Weather Warning
As we head into what is turning out to be a hot week across the East Midlands there are a few updates from the Met Office.
Under clear skies temperatures today and tomorrow will rise to around 33 Celsius inland, widely across our region which will be, unsurprisingly, the hottest days of the year so far. On Friday and subsequent days there will be a return to the low 20s Celsius – average for late June.
The sun is at its most northerly point at this time of year and for us in the East Midlands, UV levels are particularly high so protection against the strong sunshine would be very beneficial. It is worth noting that the hot dry weather also encourages people to light fires and fire up the barbeque which all come with their own hazards as does quickly entering seemingly inviting water.
Whilst today and tomorrow will be dry, slow moving thundery downpours will occur across the East Midlands on Friday will develop as temperatures rise during the morning. In the heaviest downpours 30 to 50 mm of rainfall may occur, accompanied by thunder, lightning and hail and also a gusty wind. Something to think about especially for motorists as driving conditions may be very challenging at times both for visibility and water on the ground quickly accumulating. The frequency of lightning may also affect transport timetables. As always with showers, not everyone will have a wet day and it will be a matter of keeping an eye on the radar to see where they are developing and moving.
Whilst the warning is valid until Saturday morning, across the East Midlands most of the thunderstorms will subside during the evening with a calmer night to follow.
On a possibly more positive note any rain will 'dampen' temperatures and so Friday will not be as hot as today or tomorrow.
As a result of today's updated information:
- A YELLOW warning of thunderstorms has been issued valid from 12:00 on Friday, 26 June 2020 until 06:00 on Saturday, 27 June 2020. This warning comes with a VERY LOW likelihood of MEDIUM impacts which means that:
- There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or 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
This hot weather followed by the thundery breakdown is not an uncommon scenario in the summer months but it does seem to catch some by surprise especially the speed with which a location can change from very dry to very wet and I cannot emphasise enough the MEDIUM impacts that may occur.
- The Heat Health Alert has now been raised to Level 3 for the whole of the East Midlands.
- The Flood Guidance Statement is yellow for the whole of the East Midlands on Friday and reflects the area covered by the weather warning.
Saturday heralds a return to weather arriving from the west with temperatures returning to their average for late June, in the low 20s Celsius accompanied by a more noticeable breeze. Some of the showers may be heavy and may require an additional warning and this will be kept under constant review.
Sunday looks set to be the drier day of the weekend though some generally lighter showers cannot be ruled out.
