Ottawa A/P got to 0C this morning. Bancroft had a low of -3, Petawawa -2.
Hard frost the next couple of mornings.
Saturday afternoon/evening will be gross, ie cold and damp.
Coldest period next week will be Tuesday night/Wednesday morning with a "hard" freeze, ie negative mid single digits.
Looking hopeful for the trick'o'treat-ers with a possible window of milder air before some precip.
