You may need to keep your coat and umbrella on standby this week, but looking into the coming months, a warmer and dryer winter is potentially on the horizon.
The Pittsburgh region will see some chilly and rainy days with a slightly warmer weekend, but a climate phenomenon could mean an overall milder winter in the city, said Rich Redmond, a meteorologist with the National Weather Service in Moon.
Another system bringing cold air is moving south into the overnight Monday into Tuesday and will last through at least Wednesday, he said.
That front will likely bring the coldest air the Pittsburgh region has seen so far this fall, prompting a freeze warning for the area from midnight Monday through 10 a.m. Tuesday. Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing, NWS said.
It will be wise to bundle up Halloween night for trick-or-treating. Tuesday will see a high near 45 degrees, with the evening temperatures hovering around 40.
