A Week Of Winter Ahead

The incoming cold regime will bring some rather cold temperatures by Philadelphia standards to our region ― highs on Tuesday, Wednesday, and Thursday may not break 30 degrees as we get in the grip of some pretty cold air across the eastern half of the nation.  This cold has been largely in the Great Basin so far this month ― parts of Nevada are running more than twenty degrees below normal!  Temperatures here won't be that cold, but could go down to ten degrees colder than average over the coming week.

Along with the incoming cold, light snow and flurries could cross the region later on Monday with a weak clipper and also on Wednesday with a relatively weak disturbance.  Monday's system may be more substantive than Wednesday's but either of these could bring some conversational flakes to the region, perhaps a dusting or a coating of snow.  Temperatures on Tuesday could dip into the lower half of the 20s during the day with a biting west and northwest wind as wind chills get into the single digits in spots.

A more substantive storm system lurks for Thursday night into Friday. This system could present a variety of precipitation types across the region depending on track of the low pressure center.  It could snow, rain, bring freezing rain, or a little bit of everything.  As of now, it appears that the north and west burbs will see at least some freezing or frozen precipitation at the front end of the event as cold air will be in place at the beginning of the storm.

Next weekend and into the following week (to close out January) look cold as well.  If we get snow out of Friday's storm system, we could see our coldest lows of the winter next weekend.
