In The D.Telegraph the following day I believe the weather section had
Cardiff registering a temperature of -1c at lunchtime with snow falling and
IIRC the temps in the South of England struggled to rise much above freezing
anywhere that day.
Rainfall equivalent on that date to 6 p.m.BST,and all from snow ; 0.60"..

14 april 1966 snow all day and temps near freezing what is the betting that there was a suitable volcanic euption to go with that? And some remarkable solar activity I don't doubt unless it was just another Amtomic weapon test in the atmosphere.

A deadly tornado family affected the I-4 corridor in Central Florida from the Tampa Bay area to Brevard County. Eleven people were killed across the state in what remains one of only two F4 tornadoes ever to strike that U.S.. state.[21] "Florida Twisters Kill 9", Chicago Tribune, April 5, 1966,,,

There would have been a couple of incendiaries behind that in the Kamchatka/Aleutian ranges.

The Kelud volcano in Indonesia, in East Java, erupted, sending lava and hot ash over into the surrounding area. According to the Indonesian news agency Antara, the village of Bambunan was destroyed [136] along with much of another nearby hamlet, Margomuijo.[137] The final death toll for three days of eruptions, including a larger blast on April 27, was 175 people, with another 60 missing.[138] The final toll, after the cessation of the eruption on May 7, would be 215.
