Much cooler air will settle in the midwestern and northeastern United States this weekend, prior to another warmup during the first half of October. While a major change in the weather pattern is underway, more seasonable, autumn conditions are not likely to lock in just yet.
Temperatures will not be as warm as they were during this last heatwave, but temperatures will reach the 80’s for much of Pennsylvania and throughout the mid-Atlantic states. As the cooler temperatures will linger through the weekend, some areas could see frost on Saturday. Lake effect clouds and showers are possible for the northern regions of the state as the cool air moves across.
The traditional cold spots will dip into the upper 20s around daybreak. Around the immediate shores of the Great Lakes and along the Interstate 95 corridor of the Northeast, warm waters will prevent a frost. Don’t put away all of your shorts and short-sleeved attire just yet. The sudden change to crisp autumn air will not be a sign of what is to come through all of October. Temperatures will range from 8-15 degrees above normal next week.
As next week progresses, unseasonable warmth will spread into the Ohio Valley and Northeast as well. Some record highs may be challenged since average temperatures trend downward at a swift pace during October. Enjoy the cool air while it lasts!
