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



For the forecast, a cold front in a Northwesterly flow will bring light precipitation to the area today with a descending freezing level influenced by an arctic front. FL should drop to the valley floor by this evening with an increase in the precip. An upper trough will move through later tonight prior to the ridge building for Tuesday morning. The RRR (Ridiculously Resilient Ridge) will develop a blocking pattern for sunny skies into the weekend and possibly beyond.  Should see temperature inversions by Wednesday into Thursday. Guesstimates: 10-15 cm by Tuesday morning, possibly more depending on the interface of the arctic front and the low.
