Freezing level dropped to the valley last night and will rise to 2000 meters later this afternoon. It will drop again to near the valley bottom for Monday morning and go up to 2200 meters by Monday night. Monday will be unsettled as some cloud spills in from the low to the North. Tuesday will be another sunny day with a FL well above the local peaks for the entire day ( above 3000 m). A very weak front will move in for Wednesday with a lowering FL and the chance of some light snow down to 1200 meters. (FL 1500-1700 M).

Guesstimates trace -2 cm on Wednesday?
