Hi, Seeing your remark about ice on the cars, the same was true here this
morning. It seemed strange though as my minimum recorded temperature was
3.9c (taking the lowest reading of 3 outdoor boxed sensors) Any ideas, how
high does the temperature need to rise, in order for ice not to form on cars
etc. There is obviously several factors but I would interested to know as
this occurence has happened several times in the past.

Regards

Tony

Tony,
I have known ice (ground frost) with an air minimum of above 3c, but not
above 4c so you are at the high end!

It depends on radiation loss, humidity and wind etc as you probably know.

Thanks Phil,

That's interesting, it's always been something that has puzzled me! I see
that dewpoints have been on the low side today and yesterday evening. My
location is suburban Newbury, Berkshire so not a million miles from
yourself. Another cold one on the cards tonight, it would seem

Thanks again.

Tony
