Four things you need to know about Friday, July 18
Friday, July 18, 2014, 7:30 AM - Wondering what you missed overnight or what you can expect for the day ahead?
Here's your weather briefing for Friday, July 18.
1. High pressure sets in for Atlantic Canada
After a soggy couple of days across much of Atlantic Canada, conditions have cleared as high pressure sets in.
Humidity is also expected to continue through the weekend, with temperatures feeling closer to 30 on both Saturday and Sunday.
The flow of humid air over southern Newfoundland has resulted in a prolonged period of dense fog and near zero visibility.
"Fog is expected to dissipate today along the south coast as the winds gradually become more westerly and a drier airmass moves into the region," says Environment Canada in a fog advisory issued early Friday.
Still, drivers are being urged to prepare for areas of near zero visibility when traveling.
2. Humidity builds into southern Ontario, scattered showers likely this weekend
Friday was another chilly start to the day for much of southern Ontario, but the typical July-like weather is expected to return this weekend.
In addition to the rising temperatures and humidity, scattered showers are likely throughout the region on Saturday.

"There's also the possibility for an isolated thundershower on Sunday for Cottage Country, down toward Hamilton," says Weather Network meteorologist Brett Soderholm.
3. Severe storm threat pushes into Manitoba
The "meanest storms on the continent" targeted parts of southern Alberta on Thursday, prompting tornado watches in both Alberta and Saskatchewan through the evening hours.
Heavy rain, strong winds and large hail were reported.
In some places, the hail was large and strong enough to cause significant damage to cars and windshields.
The storm has also left some communities in the dark, with multiple power outages reported.
"Similar unstable conditions are forecast for southeastern Manitoba on Friday as a front will be passing through in the evening hours," Soderholm says.
4. Much needed moisture arrives in B.C.
Showers are pushing into the north coastal regions Friday morning, heading to the lower mainland by Friday night.
"This will lead to a relatively soggy weekend, though this will give some much needed moisture for forest-fire prone regions," says Soderholm.
Up to 40 mm of rain is forecast through Sunday with locally higher amounts possible.
Widespread air quality/smoke advisories however, remain in place for many areas.
"The B.C. Ministry of Environment has issued a wildfire smoke advisory for the Cariboo and East Columbia regions because of forest fire smoke affecting the areas," the statement reads. "The B.C. Ministry of Environment has also issued a Smokey skies advisory for the entire Thompson, Fraser Canyon, Okanagan, Similkameen, Nicola, boundary and Shuswap regions."
Persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted, officials warn.
