The sharp difference in temperatures are not unusual during the “transition season” from warmer to cooler weather during the fall, NWS meteorologist Brendan Schaper said.

Normal highs for this time of year are generally in the lower 60s with normal lows in the upper 30s, Schaper said.

Less sunlight also provides extra time to cool, Schaper said.

Saturday’s high is expected to be in the upper-50s with overnight lows in the upper 30s. Upper 50s are forecast again for highs on Sunday with a 30% chance of rain.
