Heavy rain and thundery downpours forecast for the next two days

The Met Office issued a yellow weather warning for heavy rain throughout Tuesday, July 23, and Wednesday, July 24, across Lincolnshire and region.

Forecasters say further thundery downpours are likely across Lincolnshire. Temperatures in Lincoln are set to go up to 23°C on Tuesday and up to 24°C on Wednesday afternoon.

The Met Office Chief Forecaster’s assessment says: “An area of low pressure is expected to increasingly interact with the plume of hot, humid air present across parts of southern Britain.

“Whilst preceding days will have seen relatively isolated thunderstorms, the developing set-up on Tuesday and early Wednesday, provides the ingredients for more widespread and energetic storms.

“Large rainfall totals, falling in short periods (perhaps exceeding 50 mm in 3 hours) and onto hard-baked ground, may lead to flooding locally, with hail and gusty winds an additional possibility.

“As is common in such situations, not everywhere will catch the heaviest of the storms, and some places may well escape altogether.”

Monday, hottest day of the year so far

Met Office observations indicate Monday, July 22, was the hottest day of 2013 so far.

The highest temperatures were recorded at both Heathrow airport and Northolt, reaching 33.5°C, and beating the previous record of 32.2°C at Hampton Water Works on July 17.

The high temperatures were not confined to southeast England. Lincoln also had a very warm day with over 29°C in the afternoon on Monday.
