Temperatures will rise to above-normal levels once more across eastern Pennsylvania and Maryland up to the Hudson Valley on Monday. Philadelphia, where the normal high is around 67 degrees Fahrenheit, will have temperatures peaking around 70.

However, a dip in the jet stream will make way for two separate fronts to bring in waves of cooler air: one on Monday night and another on Tuesday night.

For many areas it will seem like the weather skipped over September and October and and went right to November.
