A heat dome developing in the eastern United States will bring the hottest temperatures and highest humidex values of the year so far to the Maritimes this week.
A heat dome is a large and persistent area of high pressure. The high pressure keeps the area relatively cloud free and acts as a lid of sorts to trap heat. This allows temperatures under the dome to build, day-after-day, with little relief as long as the pattern persists.
The Maritimes will begin to feel the effects of this as early as Tuesday in New Brunswick. It will peak Wednesday and Thursday across the entire region.
Environment Canada issued a heat warning for New Brunswick and parts of Nova Scotia. High temperatures on will reach the high 20s and low-30s on Tuesday, except for mid-20s on the Bay of Fundy coastline. A persistent southerly wind will raise the level of humidity in the Maritimes this week. Humidex values, or what it feels like taking into account temperature and humidity, will feel in the mid-to-high 30s in New Brunswick Tuesday.
Both Nova Scotia and Prince Edward Island will be quite warm on Tuesday. High temperatures for both those provinces will be in the mid-to-high 20s away from the coast. Areas directly on the coast will have highs in the low-to-mid 20s.
