Frost Warning

The weather in Ottawa was spectacular yesterday for the Capital City Marathon. SB Photo

Here we are nearly at the end of May and we are still talking frost. High pressure will crest over the area tonight and result in frost and freezing temperatures across Ontario, southwest Quebec and much of New England and New York. Frost Warnings have been posted. http://www.erh.noaa.gov/btv/headline/index.php
This spring has seen several 30C days but for the most part it has been unseasonably cool with numerous nights close to freezing. I expect the area around Kemptville will dip to 0C tonight, along with other rural regions of Eastern Ontario and Quebec. The area around the big cities and close to the river or Great Lakes should stay just above the freezing point at 2 or 3C.

It will be sunny on Tuesday and a little warmer, close to 19C. Low pressure organizing over the northern plains will slide into the region for the balance of the week with unsettled weather, showers and thunderstorms.
