We have an inversion!!

   As of 07:00 hrs this am we have overcast skies and unlimited visibility.


FORECAST :

A weakening warm front will bring overcast skies and light snowfall to the area this morning in a Southwesterly flow aloft. An upper level low to the south is also weakening and will bring light to moderate snowfall by this afternoon, becoming heavy later in the day. The low to the North which looked like it had potential for some heavy snow over the weekend may send most of its precipitation South. We will still see frontal bands move through the area with less precipitation as forecasted a few days ago. Model solutions are still waffling for early next week but it looks like it will remain cold with some unsettled weather. The FL will remain at or below surface over the weekend. Guesstimates: 20-30? cm by Saturday morning, 20-30 cm by Sunday morning, 20-30 cm by Monday morning.




   Warm front Friday morning, cold front fpor later in the day.
