Sawston (Cambridgeshire) weather

Headline:

Mostly cloudy overnight. Monday, cloudy with isolated drizzle.

This Evening and Tonight:

Extensive low cloud largely holding during the evening and overnight, however a slight grass frost is likely where cloud breaks do develop. Winds remaining light. Minimum temperature 1 °C.

Monday:

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

Outlook for Tuesday to Thursday:

Fairly benign start to the period, with low cloud and freezing fog. Initially remaining rather cold, however temperatures probably trending slightly upwards in more unsettled conditions perhaps arriving into Thursday.

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.
