Chilly temperatures will be with us at least through the weeekend, and realisticly until the end of next week. This, as the jet stream, the divider between warm and cold air, migrates back to the south, allowing cold air advection (a fancy way of saying the cold air will creep into our region from Canada).

The above images are courtesy of Unisys Weather. They show the 850mb level, the level of the atmosphere that meteorologists usually use to look for warm and cold air advection. You can see from them, the cooler (blue) air will stick overhead, easily into next week.
