$mrecordhightempday = '%mrecordhightempday%';
$mrecordhightempmonth = '%mrecordhightempmonth%';
$mrecordhightempyear = '%mrecordhightempyear%';
$mrecordlowtemp = '%mrecordlowtemp%';
$mrecordlowtempday = '%mrecordlowtempday%';
$mrecordlowtempmonth = '%mrecordlowtempmonth%';
$mrecordlowtempyear = '%mrecordlowtempyear%';
$mwarmestdayonrecord = '%mwarmestdayonrecord%';
$mwarmestnightonrecord = '%mwarmestnightonrecord%';
