A large area of high pressure has settled in across the mid-Atlantic for the past several days. This has brought dry conditions, lots of sunshine, and warm temperatures.

The air underneath high pressure areas sinks, which allows the air to compress and warm up. High temperatures on Sunday soared into the mid 80s, over 15 degrees above average. Trenton tied their record high today of 86 and many other areas fell short by a degree or two.

The average high temperature for today is 69 for Philadelphia. The warm dry air mass will continue again for Columbus Day with highs again reaching the mid 80s. Clouds will start to move in on Tuesday ahead of a low pressure area near Florida allowing. Winds will also switch out of the east, cooling temperatures back down into the 70s.

Rain chances arrive Wednesday and Thursday as moisture moves into the mid-Atlantic ahead of the low pressure. Another front arrives on Friday, cooling temperatures back into the 60s by next weekend.
