Winter Weather Advisories here, and for most of the GYX area except for coastal York and Cumberland counties. Advisory from 9 pm this evening through tomorrow morning. Mix of snow/sleet/freezing rain forecasted.

 

Overnight low of 25.3°F. 2.25" of new snow. Current temp: 28.1°F.

yeah, then 1"+ RN. The snow will absorb it easily, but still stings a little after all the recent events we've had.

Yes, the snow should absorb the rain we have coming. It is a bummer that it has to warm up, but we will have plenty of cover left when the warmth recedes. I look at it as glaciating a 30"+ pack, thereby bulletproofing it,  when the cold returns next week. Nothing like a rock solid base when the snow starts flying again.

I don't know where you keep getting this 1" of rain, There is no model spitting out those totals, .50-.75" is the most i am seeing and that includes whatever falls overnight tonight and friday which a good part of that will more then likely be frozen for many, The temps will have more of an effect on the pack then the precip will

Foothills progged for 1-3", then 0.1" ZR, followed by 0.4-0.5" RA.  Given how nearly all 1-3"/2-4" forecast events have been at my place, I expect 0.5" SN/IP then the ZR/RA.  Yesterday's event was forecast for 2-4" and resulted in 0.6" (which took almost 10 hr to accum), possibly the lowest for any reporting location in Maine/NH.  Still 9" above my avg thru 2/20, so no whining allowed.

 

The RA will probably knock down my 30+ snowpack to about 25", a nice platform to build upon so I can prune the apple trees from snowshoes rather than stepladder.

 

Edit:  Mr. Mannix is a firm warminista, almost into the Paul Cousons range.
