.DISCUSSION...Inversions will gradually become more pronounced as
we head into Friday as a weak High Pressure Ridge briefly builds
into the area. The next Trough of Low Pressure is expected to
swing through the area Friday night into Saturday, bringing a
round of Snow Showers to the area at the same time. Strong
Northerly winds are anticipated in the wake of the Trough Saturday
and Sunday. An active weather period is then expected to develop
early next week along with some potential for an intrusion of
Arctic air towards the middle of next week.
