It certainly is a "Winter Rain" in a "Deep and Dark December."
A strong area of low pressure will make its approach on Wednesday.
While the heavy rain associated with this system will hold off until Friday night, the cold associated with it will not. Temperatures will be falling off into the low single digits at 850 mb, and to about -7 C at 700 mb. Combined with a strong upper level trough, snow should fall on the Hermon and accumulate.
Elsewhere, expect some hail/graupel at times but no accumulation of snow outside of the Hermon.
The rain should last in Sunday and the cold will last into mid-next week.
When we look beyond mid-next week, we see some uncertainty. Most likely there will be a continued chill, but there are equal (20% chances) it will warm up a bit.
