   As of 07:00 Hrs this am we have obscured skies, variablre visibility, and it is snowing 1 cm per hour .


A weakening broad upper level trough will bring cooler and showery weather to the area today in a Southwest flow aloft. We can expect light snow fall with the FL slowly descending to about 1000 meters by tonight. Winds should abate later this morning/early afternoon. `Friday will be unsettled as a weak warm high pressure builds in the am with unsettled weather in the afternoon. The FL will slowly drop from a daytime high of 1300 meters to the surface by Friday night. A dry weak frontal band will move through Saturday with overcast skies and some isolated intermittent snow flurries. The FL on Saturday will max out at around 1000 meters and drop to near surface. A slightly more active front will move in for Sunday with light snowfall and the FL hovering just above surface. A series of weak frontal bands from a long wave trough will keep the weather active early next week with cool temperatures and more snow. Guesstimates: 10-15 cm by Friday morning? perhaps a bit more, trace-2 cm by Saturday morning, trace-1 cm for Sunday morning, 4-8 cm by Monday morning.
