I'm a day late!
however, I will take the penalty. I have to keep up my consistent run of making montly predictions!
it looks fairly dry first half of month so I'm going warm 17.8C
winter months are so difficult. 90% time I'm at least 2 degrees out. you can be 2 degrees out EVEN if you get the pattern change right. that 2010 sub zero December... I'm sure I predicted something like what I'm predicting now...
I'm going for the switch.
1.8C
