Met Office Advisor - Record-Breaking Heat with Thunderstorms later tomorrow.
Message from the Met Office Advisor: Record-Breaking Heat with Thunderstorm Risk Later Tomorrow
Across the East Midlands, the early hours of this morning brought a scattering of thunderstorms, with frequent lightning and gusty winds.
Of course, heatwave conditions continue this week, with the region expected to see some record-breaking temperatures. As a general guide, this is how the numbers now look for the rest of the week and into this coming, less hot, weekend:
- Today: daytime highs of 28C to 33C with lows overnight into Thursday of 17C to 20C
- Thursday: daytime highs of 33C to 37C with low overnight into Friday of 18C to 22C. We are now expecting the UK July record of 36.7C to be broken and there is now a 70% chance of the all-time UK record of 38.5C from August 2003 to go. For the East Midlands, the area's most likely to see the very highest temperatures look set to be Northamptonshire, Leicestershire, Rutland, as well as southern parts of Lincolnshire, Nottinghamshire and Derbyshire.
- Friday: daytime highs of 26C to 31C with lows overnight into Saturday of 16C to 19C
- Saturday: daytime highs of 24C to 28C with lows overnight into Sunday of 14C to 16C
- Sunday: daytime highs of 24C to 28C with lows overnight into Sunday of 14C to 16C
Meanwhile – and in line with the Public Health England and NHS England Heatwave Plan for England, the Heat-Health Watch status remains at Level-3 indicating a 90% risk of meeting trigger temperatures across the East Midlands from now until 0900 on Saturday.
In addition to the heat – later on Thursday we have another risk of scattered thunderstorms developing with potential impacts across the region – and a Met Office Yellow Warning for Thunderstorms has been issued for all parts of the East Midlands.
This Thunderstorm Warning is valid from 1500 Thursday until 0400 Friday and brings a Very Low Likelihood of Medium Impacts, which means:
- spray and sudden flooding could lead to difficult driving conditions and some road closures
- where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- there is a chance that power cuts could occur and other services to some homes and businesses could be lost
- there is a small chance that homes and businesses could be flooded, or damaged by lightning strikes, hail or sudden gusts of wind
Of course – and as is usually the case with thundery activity, nailing down the exact locations that may see potential disruption from thunderstorms is very challenging.
Once this thunderstorm risk clears Friday morning, another (less) hot day is likely Friday. Although highly uncertain in details – further thundery activity is possible later Friday and into the forthcoming weekend.
Please call if you have any questions or queries and further email updates will be provided as and when required.
