I'll add that i've not seen sleet in North Devon yet either.
I have however seen hail... but since i've previously seen a covering
of hail before during a summer thunderstorm, that isn't saying much

During a shower last Saturday, there *might* have been one piece of
sleet amongst the hail, i wasn't sure. Temps were still high at the
time, i find it hard to believe it was one isolated wet snowflake. Or
my eyes were playing tricks in the semi-daylight

Winter poo.... bring on the spring-time storms
