    As of 07:00 Hours we have overcast skies and variable visibility, and it is snowing lightly.

For the forecast, the cold front pushed through early this morning with an upper trough following in its wake. We can expect overcast skies today with light snow in a Southwest flow aloft. A weak ridge of high pressure is close by so we may see some breaks this afternoon, but unlikely. The freezing level will hover around  1000 meters. A stronger--warmer--wetter front pushes in on Friday into Friday night with moderate snowfall and strong winds. The FL could rise to 1400 meters on Friday morning, dropping to around 800 meters by Friday night. At this time Saturday is looking unsettled as a ridge begins to build into the area with a cool Northwesterly flow aloft. We will likely see a weak short lived frontal band for Sunday morning, then the ridge rebuilding for the late afternoon/evening. Monday into Tuesday, we will see a warm off shore flow bring rising freezing levels to the area with mostly sunny skies. Guesstimates: 6-8 cm for Friday morning, 20-30 cm for Saturday morning.

   Trough moving through, chance of some breaks.

    Trough with light snow for today.

    Front for Friday into early Saturday morning.

   A front to the North will touch our zone early Sunday morning with some light snowfall.

   High pressure will bring warm temperatures into the area Monday into Tuesday from the South.
