April starts with HP to the SW and LP to the N, bringing mild maritime air after a cloudy and damp start. Warm front on 2nd delivers very little rain but a rather dull day. HP drifts slowly towards the far SW on the 3rd, filling by the 4th. Cold front and troughs sweeps down from N bringing showers on 5th pm and evening.

On the 6th a very active trough moves down from the N with polar air behind it. Continuous snow falls for 8 hours with a patchy covering of up to 4cm on some surfaces - the coldest April day in my records. From the 7th, LP brings less cold Polar Maritime airstream with sunny periods. Occlusion and trough brings showers pre-dawn of 11th followed by heavy shower with small hail pm. More showers early morning of 12th and downpour during afternoon with thunder. More heavy showers with small hail 13th.

The unsettled theme continues on the 14th with sunny periods to start before troughs moving down from the north bring more showers during pm. A weak ridge of HP reduces the number of showery downpours before LP tracks towards Biscay on the 16th with HP to the N of Scotland, delivering two gloomy days 18th and 19th.

Weak ridge of HP extends slowly toward UK from the Azores. Moderate rainfall early morning 21st, and light rain morning of 23rd after fog. Thundery showers with hail on 24th afternoon. HP moves to NW France, then eastwards.

LP approaches Cornwall. Two spells of rainfall on the 29th, showers in the morning and steady moderate rain with heavier bursts late afternoon. Staying unsettled on 30th as LP moves N across the UK, spell of moderate/heavy rain in the morning and showers later.
