Having just recovered from the New Year festivities(!) I've
realised there were some examples of identical maximum and minimum
temperatures reported in the January 2nd SYNOPS. Heathrow at 5.4/5.4
and Solent at 5.8/5.8 for example.

Obviously, with the way max and mins are reported, this can happen on
any cloudy/windy Winter day if a colder airstream moves in during the
morning but it always strikes me as odd when it does happen, quite
misleading really. The true 00Z/00Z max/mins at Solent near me were
about +7C and +1C respectively.

I'm sure this has been debated many times before (though I can't find
it at this unearthly morning hour) but could someone please remind me
of the logic underlying the reporting of daily extremes in this way?
It never ceases to irritate me whenever it crops up! Grrrr!
