    As of 07:00 Hours we have overcast skies with unlimited visibility at 1860 meters.

For the forecast, the low pressure system is moving East in a Southwest flow aloft and a high pressure aloft will begin building in the area this morning. We will have unsettled conditions later this morning into this afternoon with the chance of post frontal flurries this morning. Mostly cloudy later this afternoon and some breaks this evening. A weak warm front will move into the zone for Saturday in a Westerly flow with freezing levels rising to 1500 meters. We can expect light snow tomorrow morning into the evening when it will begin snowing moderately. The front will continue into Sunday and the freezing level will slowly descend to 1000 meters by Sunday evening. The ridge of high pressure at the surface and aloft redevelops on Monday with unsettled conditions into at least Wednesday.  There is a good chance we will see light snowfall by Wednesday evening. A warm air mass will likely result in inverted temperatures and stratus cloud development in this time frame. Guesstimates: 10-12 cm by Sunday morning, 12-15 cm by Monday morning.
