After such a wet, warm and humid September, the change in seasons has not surprisingly brought a change in the overall weather pattern.

The current medium range models show several jet stream dips, allowing colder air to enter into the PHL area.  The dips also create a stage for low pressure development.

Historical average temperatures this week are 43 low and 61 for the high. Our temperatures will depart from these averages over the next several days.

Currently, a dip in the jet stream will bring relatively cold temperatures for Thursday and Friday.  A brief warmup on Saturday will precede another front moving through on Saturday.

The approaching front may give us some showers Saturday and will result in colder weather for Sunday and Monday. Lows may be near freezing Sunday night.

As someone who looks at the weather maps each day as my daily crossword puzzle, I can say that the weather this year has been a wild ride.  The rest of October currently looks to be equally interesting with the possibility of a large coastal storm the end of next week.  Stay tuned.
