Calm before the storm?

Today sees the air pressure rising and we are set for a mild day.  Our top temperature will be around 11c and overnight the minimum air temperature will be around 8c.   Interestingly the air temperature will be at its highest during the late afternoon when a change in the wind direction will bring warm air from the S/SW.  The average wind speed today will be around 2mph this morning/afternoon increasing to around 8mph this evening.

The synoptic charts (air pressure) for the middle of the week (see below bottom chart) are showing that a low pressure system will be moving across the country and the indications are that it will be a wet and breezy time.  I will give more detail on this situation nearer the time.

In contrast today’s air pressure chart (see below top chart) shows that most of the UK is under the influence of a high pressure system and this will see reduced / calm winds and only light rain / drizzle for the vast majority of areas (ours included).

The radar images are showing that there is a band of rain just to the south of our area.  This does bring a 55% risk of some light rain / drizzle in our area but, in general, it will be a dry day.

It certainly would be a good day to get out for a walk or cycle and blow away the cobwebs for the last few days excesses.
