While the GEFS ensembles are not showing too much in the way of below normal temperatures later this month, the GFS operational has a pretty decent cold shot around the 28th into the 29th. This is about two weeks away, so this actually happening is not guaranteed. But if it does happen, pumpkin spice and all the fall things will abound.
Below are the projected anomalies below normal for much of the eastern half of the U.S. on Sept 29th:
Morning lows could be in the upper 40s for much of the Carolinas, providing the first true fall chill, just after the arrival of fall. This would require some to wear a light coat when leaving in the morning.
This is not a slam dunk forecast, but rather a signal that needs to be watched for the end of the month. As such, frost may not be too far around the corner, at least for locations away from the coast.
