Letchworth (Hertfordshire) weather

Headline:

Rain clearing overnight. Monday, some heavy showers developing, perhaps thundery.

This Evening and Tonight:

Outbreaks of rain, locally heavy, will continue to slowly move eastwards during the first part of the night. Rain clearing shortly after midnight, becoming drier with clear spells and winds easing. This may allow a few fog patches to develop. Minimum temperature 11 °C.

Monday:

Showers soon spreading from the west, locally heavy with the risk of hail and thunder. Strong winds developing in places, more especially around the coast. Maximum temperature 15 °C.

Outlook for Tuesday to Thursday:

Tuesday, bright intervals and occasional showers. Wednesday probably mostly dry, perhaps turning wet and windy later. Thursday, windy with showers or longer spells of rain. Cooler.

Remaining unsettled to start the period as an area of low pressure clears into the North Sea. Outbreaks of rain, heavy at times, and strong winds will likely ease through Friday as the low continues to move eastwards. This will leave a colder northerly flow for a time at the weekend which will be showery around the coasts but with sunny spells inland. Into the following week, conditions are expected to be changeable with showers or longer spells of rain across many parts of the UK. The cold northerly will likely give way to a more changeable westerly pattern and the wettest weather will probably be in parts of the north and west. Temperatures are expected to be close to or slightly below normal for the time of year.

Changeable and unsettled with weather systems spreading from the west. These will bring spells of rain, heavy at times, and some strong winds, interspersed with drier, brighter, and less windy periods between systems. The heaviest rain will probably be across northern areas at first, migrating to western areas later. Temperatures are expected to be close to normal or perhaps slightly above.
