Tilshead Borehole Levels: 20th December 2020

The water level in the Tilshead borehole has risen steadily over the last week.  As I have mentioned in previous years, at this stage of the season, the aquifer is fairly insensitive to rainfall as it requires a large amount of water to create a small increase in depth.  As the aquifer fills and the water level gets to the 90m AOD point, then the sensitivity increases massively.  If current rainfall trends continue, I wouldn’t expect that to happen for 3 to 4 weeks at least.

So, what might we expect with the weather in the run-up to Christmas, the New Year and a little beyond?  Well, although Sunday morning is bright and clear, wet weather moves in later and we can expect longer and heavier spells for rain on Monday, slackening off a bit on Tuesday and Wednesday.  Christmas Eve should be fine, but expect rain on and off from Christmas Day through to the New Year.   It is getting colder over this period and snow is expected in the north and east of the country on high ground, but I expect we shall miss it as usual.  Beyond that, expect a period of cold and dry weather.
