Fog and mist today cold by the end of the week.

The early fog and mist may create a few driving hazards on the way to work or school this morning so care needs to be taken.  The dew point is within 0.4c of the air temperature and this would indicate that, in places, the fog could be dense.  With the mist will come the drizzle like dampness in the air.

The mist will slowly clear this morning but we are currently under a heavy cloud covering.  This will prevent any real periods of brightness today.  We will, however, reach a pleasant top temperature of around 14c.  Overnight this will fall to around 11c.

When the temperatures begin to cool down later this evening the mist will begin to reform and remain with us throughout the night.

As we are currently under a system of high pressure the winds will remain light (average speed of around 4-5mph) and will be blowing from a ENE-NE direction.

The jet stream will change position as the week passes and by the end of the week we will receive an icy blast from the N- NW (see jet stream image for early Saturday below).  The change will begin on Thursday and remain with us right through the weekend.  Gardeners need to consider how they will protect any tender plants.
