The Maritimes will enter the hottest stretch of its current heat wave on Wednesday and Thursday. Heat warnings continue in the region with relief still in sight by Saturday. Heat warnings continue Heat warnings posted by Environment Canada on Monday continue for much of New Brunswick, all of mainland Nova Scotia, and all of Prince Edward Island. The warnings call for daytime highs of 28 to 33 degrees with the humidex making it feel 33 to 41 through Thursday. The nights will be warm with low temperatures no cooler than a range of 16 to 20 degrees. Coastal areas will have more moderate temperatures, especially the Bay of Fundy coastline in New Brunswick and the Atlantic coastline of Nova Scotia. Heat warnings were expanded into Cape Breton late Tuesday afternoon by Environment Canada Hottest areas on Wednesday, possible records? The hottest parts of the Maritimes on Wednesday include southwestern and eastern areas of New Brunswick (away from the coast), and the interior of mainland Nova Scotia. Those areas have the highest chance of reaching high temperatures of 32 to 34 degrees. If you are looking for spots where the temperature may be more moderate, you’ll want to head to the coast. That is especially true for the Bay of Fundy coastline in New Brunswick and parts of the Atlantic coastline of Nova Scotia. Those coastal areas will have a more persistent onshore wind off of cooler ocean waters. Just be aware it may not be a perfectly picturesque beach day for those areas. The same onshore wind may keep some low marine cloud and fog trapped in closer to the coast. Sunnier beach weather is more likely to be found on the eastern coastline of New Brunswick, the north shore of Nova Scotia, and on P.E.I. Despite the soaring temperatures, it may be difficult for many high temperature records to be set Wednesday. The reason for that is the standing record highs for a July 16 in the Maritimes are already mostly in the low-to-mid 30s. Humidity to break for Saturday Weather conditions continue hot and humid for Thursday. A weak cold front moves into the Maritimes on Friday and brings a more widespread chance of showers and thunderstorms. Air moving in behind the cold front is out of the north of the country and is less humid. That will filter into the Maritimes Friday night and Saturday morning. The effect of that drier air will be to lower dew point temperatures, a measure of moisture in the air, down to the low teens, which for many is a more comfortable level of humidity.
