Windrush Weather

Unstable weather from another depression

There were many hours of sunshine on Wednesday but a couple of very light showers occurred mid-morning that amounted to 0.3mm but nothing thereafter. The wind was very strong during daylight hours, peaking at 30mph again in the afternoon. The thermometer eventually peaked at 14.4C, logged at 14.41, being just 0.3C above average. As the skies cleared in the evening the thermometer began a steady fall reaching a low of -1.5C at 05.44. Analysing the minute by minute data stream the air frost began at 02.55 and only returned above freezing at 06.58, thus four hours of freezing air. Thankfully, my apple blossom is yet to unfurl, so no damage last night.

After dawn on Thursday the sun began to work lifting the temperature to 4.4C by 08.00, however, it was the coolest start to a day at that time since the 10th (4.1C). The wind will be much lighter today, changing direction from an easterly quadrant first thing to a south-southwest air flow this evening.

We are now under the influence of another major depression, centred in the western approaches, so the unstable weather pattern continues with sunshine and the likelihood of showers occurring. There is the possibility of fair weather clouds, cumulous clouds, occurring again today. As the warmth increases the moist air rises, condensing into white, puffy clouds.

This depression will, as yesterday, move northwards up the western side of the UK, principally later today and on Good Friday, so once again we are likely to be on the periphery of any substantial rainfall.
