Atlantic Canada will be unsettled Friday as the week draws to a close. The Maritimes will deal with leftover moisture from what was once known as Tropical Storm Fred Friday, while Newfoundland will see some wet weather from a separate system. However, neither are expected to produce much, other than some moderate rainfall and the chance for non-severe storms. What has the attention of forecasters is Tropical Storm Henri, whose trajectory may push it into Atlantic Canadian waters early next week. What we know, below.
FRIDAY: REMNANTS OF FRED BRING RAIN, THUNDERSTORM RISK TO THE MARITIMES, A LOW BRINGS RAIN TO NEWFOUNDLAND
Remnant moisture of what used to be Tropical Storm Fred is trekking through the Maritimes on Friday morning. It won't be substantial, but the leftover atmopsheric moisture in the atmosphere has sparked some thunderstorms across parts of the region Friday morning.
The threat will continue in the afternoon hours as the cold front sweeps southward in the Maritimes, with much of New Brunswick and most of Nova Scotia at greatest chance of seeing non-severe storms fire up. Conditions will improve in the latter province Friday evening.
Meanwhile, across the Gulf, a low-pressure system will trek through Newfoundland from north to south Friday. It could also spark non-severe thunderstorms in central areas of the island. Not much rainfall is expected, but the system will lift the heat that's been prevalent in recent days. Rain will move out in the overnight hours.
Rainfall amounts in the Atlantic will be moderate, with totals of 5-25 mm across southern Maritimes and Newfoundland.
The front will elimimate the heat and humidity in the Maritimes, dropping temperatures back close to seasonal for most. Conditions will be fair for the Maritimes on Saturday, however, and it will be a much cooler weekend for Newfoundland, as well.
After a humidex of 25 on Friday afternoon, St. John’s will see a high temperature of about 16°C on Saturday.
THROUGH NEXT WEEK: WATCHING HENRI AS IT DRAWS CLOSE TO THE MARITIMES
The wery warm and humid weather won't stay away from the region very long, as it is expected to return to the Maritimes next week, along with the risk for showers and thunderstorms.
The bigger story will be Tropical Storm Henry and where it will eventually track over the weekend. It is expected to strengthen in the western Atlantic Ocean, likely to become a hurricane by Saturday.
The latest forecast from the U.S. National Hurricane Center brings Henri close to New England by Sunday. A complicated atmospheric setup will determine where Henri tracks once it approaches the region early next week.

Environment Canada issued a tropical cyclone statement for Nova Scotia Thursday.
"The storm will probably not affect our weather directly until Monday and/or Tuesday, and depending on the intensity and size, may simply bring moderate wind and rain," the agency says. "Larger than normal surf conditions will develop on the Atlantic Coast of Nova Scotia this weekend."
It’s still too early to know the exact effects the storm will have on Atlantic Canada. We’ll likely know more by this weekend.
