For the forecast, a warm moist frontal band will bring moderate precipitation to the area this morning with the Freezing Level rising to 2000 meters by this afternoon in a Southwesterly flow.  We may see a lull in the precipitation sometime this morning but we should see it ramp back up and bring moderate to heavy precipitation into this evening. A cold front will pass through the area later in the day and we should see the FL drop to around 1600 meters by the evening.  An upper level trough will bring cloudy conditions for Saturday with light precipitation expected through the day. A very weak upper level ridge will build Saturday night into early Sunday with mostly cloudy skies, some breaks and the chance of some isolated showers with a FL hovering around 1300 meters. A weak cold front will bring some light snow to the area Sunday evening. Early next week we will see a showery cool weather pattern with FL dropping to as low as 1000 meters and hovering around 1300 meters.
Guesstimates: 20-30 cm above 1800 meters by Saturday morning.  5-10 cm above 1300 meters during the day Saturday. 5-8 cm by Monday morning.
