I didn't want to jinx it yesterday - but what an incredible day it ended up being! As you'll know, the only way to get a notably low daytime max this time of year is to get rid of the sun, but a July day with thick, overcast conditions all day is exceptionally rare.
We ended up having one here yesterday, with a bit of light rain to boot. That means the warmest temperature was actually overnight, winter style - 16.3C. The daytime max was 16.0, and there was a remarkably low noon (GMT) temperature of 14.9C - the warmest day of winter, February 15th, had a noon temperature of 14.1 and an afternoon high of 15.9.
16.0 is a good 6C below normal.
I don't expect a repeat any time soon. Today's off to a great start (12.2 at 6z), but today's high is meant to be a few degrees warmer than yesterday's.
Again, 6C
above normal (28 for here) wouldn't make people bat an eyelid!
