Rhobell Fawr (Gwynedd) weather

Headline:

A bit brighter and less cold on Monday.

This Evening and Tonight:

Staying largely dry and cloudy overnight with any clear spells giving rise to patchy mist, fog and frost forming. Thickening cloud in Anglesey and Gwynedd later with showery rain and drizzle possible by dawn. Minimum temperature -1 °C.

Monday:

Any fog patches lifting then mainly dry with bright or sunny spells. Often cloudy though with the chance of showers in the north and far southwest. Feeling a little milder. Maximum temperature 7 °C.

Outlook for Tuesday to Thursday:

Mainly dry, cloudy and chilly at first with frost and fog in places overnight. Showery rain in northwest Wales on Tuesday, then wetter and windier and somewhat milder on 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.
