Windrush Weather

Sun returned on Monday but still wind chill from 33mph winds

Another significant fall of snow occurred Sunday night into Monday with the equivalent of 2.1mm of rainfall.

On Monday the thermometer slowly rose above freezing to register a maximum of 3.2C at 15.04, thanks to 5.8 hours of sunshine. However, The strong winds, gusting to 33mph, meant a wind chill factor all day. A significant feature was the highest UV reading since the beginning of October.

During Monday evening the winds initially gained in straight before falling much lighter in the early hours. This was due to the barometric pressure rising rapidly, to its highest reading this morning, which meant the isobars were much closer together and therefore a steep pressure gradient resulting in the strong winds

There was a slight fall of light snow overnight and between the gaps in the increased cloud cover, the thermometer fell to a low of -0.5C.

Tuesday has arrived with cloud much higher and thinner with occasional glimpses of the sun. After the slight and short air frost overnight the temperature recovered to read 2.3C at 08.00. The notable feature this morning is that the wind has backed from the northeast into the north and abated. Wind from this direction is less cold than that from Siberia, thankfully.

Tuesday update at 13.30: temperature struggled to reach a maximum of 6.4C at 13.15, just after a short burst of sunshine, which is in short supply today, less than half an hour at the moment. The brisk north to northeast wind is giving a wind chill so that it feels more like 3C.

Tuesday update at 15.00: late short burst of sunshine pushes thermometer to a maximum of 7.1C at 14.15, which was still 3.4C below the average. We still have several cms of snow around the bungalow, where drifts up to 40cms built up in the high winds, although most of the less deep snow has melted away.

Tuesday update at 19.30: temperature been dropping away for past three hours, now down to 3.7C and still falling slowly. It is likely to be a chilly night as the ground is still very cold (0.7C at 08.00 this morning)from the snow and frost of recent days. The thin cloud will do little to stop radiation of any ground warmth into the atmosphere.
