Above Normal Continues; Cooler for the Weekend; Earl to strike Nova Scotia

Heat and Humidity Continue....

Above normal conditions continue across Southern Ontario and around the Golden Horseshoe today. A southerly flow ahead of a slow moving cold front will help to keep the temperatures into the high 20's to near the 30 degree mark for all centres across the region. Humidity will also make it feel into the high 30's.

A HUMIDEX ADVISORY remains in effect for the area as humidex values will be near 40 for the 4th day in a row. Scenes like this were common place across Lake Ontario and up through cottage country as people were trying to beat the heat.

Showers and thunderstorms are likely to develop along and ahead of the cold front as it interacts with the warm soupy airmass. Behind the front, much cooler air will filter into the regions. There is the chance that some of the thunderstorms that do develp will reach severe limits, but the main threat is strong gusty winds. The timing of the front will also play a big part in the amount of storm activity we recieve. It's expected to arrive overnight and early morning, when daytime heating is at the minimum.



Hurricane Earl aiming for Nova Scotia

The main weather story is Hurricane Earl. Currently a Category 4 Hurricane, the path of Earl is expected to take it right over Nova Scotia. Earl is expected to weaken before it hit's, however it still could be a Category 2 storm. Residents are preparing for the worst as memories of Hurricane Juan still linger in many peoples minds.
There still remains some time that Earl could strengthen to a Category 5 hurricane before entering cooler waters. It will be going through an eyewall recplacement cycle today and the new eyewall will be forming as it crosses the warm Gulf Stream.
