Well I am thinking the Barometric pressure has a lot to do with the flow too and that would probally follow high and low temps.

It's been over 30.1 and pretty much steady there except for a few drops but not huge drops and today it dropped down to 29.5 and it's starting to flow a little more...below 30 tonight and tomorrow night so I hope my FLOODS coming!

I don't make Syrup to pay the bills... I'd be too afraid I'd end up Living in a 300 Year old Hollow Maple tree! LOL!
