Danny update and FROST!

In what has seemed like the shortest and coolest summer ever, frost is in the forecast. Arctic high pressure will crest over the region tonight and the likelihood of scattered frost away from the metro areas and waterways is very possible. Frost Advisories are in effect for central Quebec and the Adirondacks of central New York. Last night Montreal dropped to 9C while Kemptville reached 6C. The cool air will move east on Friday as a warm front moves into the region.

The weekend forecast is up in the air at the moment. A trough of low pressure will slide east from the Great Lakes, and give the region a chance of showers both Saturday and Sunday. The showers could turn into a full blown rainstorm if Tropical Storm Danny comes close to the US coast. However, at this time, each computer run is pushing the storm track further to the east. There is still great uncertainty in the forecast strength and track. We will have to keep an eye on the storm. The greatest risk for a direct impact is from Cape Hatteras north to Newfoundland, with the fringe affects being felt across interior New England and southern and eastern Quebec, New Brunswick and PEI. Stay tuned!
