It's the last day of October and we’ve got some beautiful weather ahead for Monday, but tonight it gets chilly in a hurry for Halloween trick-or-treating.
The steady, drying breeze blowing Monday morning, will die down later in the day. Monday evening, the recipe for chilly weather this time of year – very dry air in place and clear skies – will be in place. The sun sets just before 6 o'clock, so expect temperatures to be dropping rapidly. Early in the evening the readings will be in the 40s for our entire Philadelphia area.
The later you stay out trick-or-treating the colder it's going to get. So your younger ghosts and goblins might need an extra layer as they go searching for treats.
Also, with a new moon and no clouds to reflect city lights, it will be very dark by 7 o'clock Monday evening. That’ll make it difficult for drivers to see children, especially those dressed in dark costumes. If ghosts and goblins are going to be out after dark, it’s a good idea to have them carry a flashlight to make them more visible to motorists.
