The end is near for these above-seasonal temperatures on the East Coast, courtesy of a cold front set to slice through the region, triggering showers and thunderstorms as it goes Thursday, and into Friday for Newfoundland. Cooler temperatures are beyond, but showers and storm risk return at the end of the weekend. A closer look, below.

THURSDAY: HOT TEMPERATURES FUEL THUNDERSTORMS
Much of the East Coast is bucking the trend experienced by the rest of the eastern half of Canada in recent days, with temperatures 5-10 degrees above seasonal.
Thursday looks to feature more daytime highs in the upper 20s, with accompanying humidity, which makes the warmth a double-edged sword, as that humidity will fuel showers and thunderstorm risk.
Presently, that risk looks to be non-severe in places where storms are likely to spark, but still widespread. New Brunswick sees storms arrive through the afternoon, and they'll be ongoing through the overnight for Nova Scotia.
Newfoundland doesn't bode well for thunderstorm risk, but eastern parts of the island are set to experience the most rainfall through Friday from this system.
Temperatures are expected to drop to more seasonal values behind the front on Friday.
WEEKEND AND BEYOND: MORE FALL-LIKE CONDITIONS WITH SOME SHOWERS
Beyond, the weekend looks to feature temperatures better suited to early fall across the region, marked with a few showers for western and central Newfoundland Saturday. More widespread showers and thunderstorms move in Sunday night across the Maritimes, and into Newfoundland Monday.
"There'll be a brief warm-up with the system, followed by a shot of chilly weather for Tuesday and Wednesday, then a warming trend for the end of next week," Weather Network meteorologist Dr. Doug Gillham says.
