Knebworth House (Hertfordshire) weather

Headline:

Mostly cloudy, with isolated drizzle.

Today:

Cloudy for much of the day, with isolated outbreaks of drizzle possible. Rather cold to start, although temperatures perhaps creeping upwards later, with any brighter intervals expected to be limited. Maximum temperature 5 °C.

Tonight:

Remaining mostly cloudy overnight to the north, with outbreaks of rain or drizzle continuing. Drier and clearer spells are expected to the south where it will be cooler. Minimum temperature 0 °C.

Tuesday:

Some brief bright or sunny spells possible initially after any early fog clears. Cloud thickening and lowering once again from the southeast through the day. Staying largely dry. Maximum temperature 6 °C.

Outlook for Wednesday to Friday:

A mostly cloudy Wednesday, with drizzle clearing east. Cloudy with rain Thursday, then windy with cloud and rain Friday. Trending milder, though clear nights will allow cold nights.

The change to much more unsettled conditions will begin on Friday as a deep area of low pressure, which is yet to develop, will be steered towards the UK on a powerful Jet Stream - fuelled by the recent cold spell over North America. A wet and windy few days are likely, with some snow in the north for a time, and then a continuation of these periods of rain followed by showers, often accompanied by strong winds, looks likely for the rest of the month and the start of February. There is the potential for weather warnings or even a named storm at some point. Temperatures at least should recover in most places, ending up a little above average, though admittedly not feeling like it at times.

The start of February is likely to continue on an unsettled and relatively mild theme, with periods of rain, showers and strong winds, alternating in most parts with short-lived brighter and cooler interludes. Pressure may build across southern areas towards mid-month, which would result in longer drier and more-settled spells here, albeit with an increased chance of overnight fog and frost.
