Tuesdays low was 38F and todays low has been 37F.
Normal high and low for the date is 67/45, so it's going to be and has been 5-10F below normal this week.
I have attatched a compiled list of 'norm' highs and lows for my area.
(I had a total list of norms for the whole year but I lost them so I'm working on the other 9 months as we speak)
