A wave of low pressure may develop along an arctic front that will be sliding through the Metro Region on Wednesday afternoon.

While it is too soon to know for sure how strong this system will be and how quickly it moves, some forecast models drop between a trace and 3″ of snow on our area during the day on Wednesday through the late evening hours.

• The image below is just showing precipitation amounts (basically showing up to a tenth of an inch of liquid… which depending upon temperatures and snow to liquid ratios could drop between a dusting and 3″)

Again, this is still 4 days out, so while there are no guarantees, this may be the first shot at seeing some widespread snow showers across our region this Winter Season.
