It’s such a beautiful day, greenhouse was overheating briefly! It’s in early winter mode (expecting single to low double digit daytime highs with cloud and sub zero nights) so it took longer to cool off with the ventilation. It’s a balmy 23 degrees outside with sunshine #ONstorm

Some model comparison "think" for rainfall estimates (in mm) for the week -till 7AM Sat. The focus for the greatest rainfall for the week is in NONT- Mainly NWONT entering W. NEONT sections. The CAN is the wettest overall. #onwx #onstorm

I’m not saying this weather forecast is 100% accurate, but going into November we’re not going to know it’s November in Southern Ontario. There’s no signs of winter on the immediate horizon.

Quick Model comparison between the EURO & Canadian for this upcoming week...while it will be mild for the week, the threat increases for more "unsettled weather" near mid-week into the weekend for SONT. The bulk of more active weather remains in NONT for the week. #onwx #onstorm
