That Snowpack!

I saw it’s gonna be in the 50s/60s next week in Pa with some rain

There is no swowpack in PA obv, BUT i do think it helps groundwater recharge that snow melts normally slowly and allows most or all the water to get absorbed into the water table vs running off. After the summer and fall we had rain wise i will take any precipitation any time heading into the spring

only helps ground water if the ground is thawed. here in tioaga county its all run off in the spring. only a few places where it would help. frost stops penatration of water

The ground thaws slightly as the snow melts slowly each day was my assumption. Take your lawn example, it starts hitting 40 and the snow dissappears slowly day by day. There is no visible runoff, i assumed that moisture slowly soaks in. I'm sure it refreezes in the ground each night once absorbed but its there
 
the thaw of snow in the valleys and ridges around the Spring Creek and LJ has produced a very little bump that's going back down. We didn't have much snow up to this point and its mostly gone. I am hoping what melted made its way to the water table, but it wasn't a lot.

In my very amateur opinion, all moisture helps, Joe!

Modeling guidance suggests above average precipitation for February. We will see...
 
If you think about it snow pack actually insulates the ground. An early snow will keep the ground temperature between 30-32 degrees. The temperature of the snow never gets below 32. However if it is densely packed it reduces the insulating factor.

I had a double take there myself, but I think he is saying that the ground temperature will determine the temperature of the snow pack that is insulating it, which is mostly true.

Yeah. I know snow is a great insulator, but if it's 0°F out, maybe some of the snow is 32°, but that snow closer to the air and away from the ground is certainly colder than 32°. Right?

Kinda of geeky, but I had look. Here is a map of the different ice sheets that advanced into PA. Looks like they only ever came so low as the NW and NE corners of the state. I think there were about four continental glaciers that came into Pennsylvania, forget the details.

Funny. The little cross roads I live by outside of Franklin is called Mapledale. That orange strip is called Mapledale Till. There are strips and small seams of sand underground.
