Yea let's see if we can play the February temperature gradient and make this a 4-8" overrunning event hmm???

Now these types of systems can be very sneaky in February. We have the southern zones heating up more rapidly and then we have our cold grounds now with snowpack just to our north with us being colder relative to what's going on to our south. This could set up quite a temperature gradient for snowfall to band and set up an overrunning event with decent accent / lift. Don't sleep on the possibility of the system midnight Saturday to 12 pm Saturday to be an overperformer!

My low for today just happened right now I am at 28.7f the lowest temperature from this morning between midnight and 6 am was 32.4f thanks to the clouds off of the Great Lakes higher humidity and dewpoints capping temperatures.

I like what you are saying about snow on snow. That is NOT the case down here anyone east of the Blue Route 476 in Delaware County now have zero snowpack. It was an amazing ride this morning from Media driving ESE 7.4 miles to zero snow and also a temp in Media at 31f to a temp with no snow on the ground at 38f. The differences from Central, Western, and Northwestern Delaware County to the River were in one word DRAMATIC when it came to snowfall accumulations from yesterday.

Kamu and I will take the 3-5" sweet spot for $1,000 sold!

Come on come on..... Double or nothing baby come on!! Hmm with all this talk of water vapor on the other forum maybe we can go 3-6" here.

It's yet another variable into our "unknown". I am sure (the main term here that you used water vapor) being launched high up into the atmosphere MUST have an effect on our climate for sure.

I look at this differently welcome to the new normal?

You certainly missed one besides intensity elevation played a huge role. Look at the Fall line! The heavy snow matched perfectly to the fall line snow 6"+ was north and west of the fall line.

And there it is elevation and warmer air trapped along the Delaware River. Think my totals for Delaware County last night were spot on from what I saw.

39 partly sunny here rapid melt off on-going. Total snowfall here in Media 3.3" before the compaction took place. I drove 2 miles south to lower elevated side of Media clearly less.

clearing pressing down from the NW now pretty interesting signatures on the radar on the back end looks like little bursts of snow.

snow picking back up here in Media power just went off for a few minutes 32.9f Total snowfall 2.6"

Light to moderate snow here 32.7f dewpoint 32f pressure 29.44 wind NE 15-22. measured 2.4" I think my 2-4" for Media will work out. I am very curious to see how the southeastern zones of Delaware County are doing I bet they are like 1-2" down along the River say Folsom, Ridley, Glenolden, Sharon Hill, Colwyn I am sure elevation is doing its thing the way the changeover moved through. Anyone in the Newtown Square area to Radnor and Wayne would love to know your snow totals too gives a flavor of elevation. Kamu snow Garnet Valley probably same as Media 2.4" or so? Checked out Ocean City Maryland last hour 29.29 981.8 mb so that's your storm and energy over DCA transferring to the Coast has been in progress. Back edge moving on down from the NNW and NW. They probably did not get much out in State College.

Snow in past few minutes has really lighted up here clearly see the banding setting up along the Route 202 corridor moving NE. Call it light to moderate snow here now 32.7f about 2"

Heavy Snow past hour and still coming down clearly 1-2" an hour rates eyeballing it we are likely around 2" or so here in Media Delaware County 32.7f. 4 am a bit of sleet mixed with rain 5 am more sleet mixed with rain 6 am 100% sleet 6:15 am 100% snow has been snowing since.

That's classic take a look at the radar down there in NE Kentucky Wow! A clear center and another racing up from the south almost looks like they want to co locate.

42.1f humidity 95% dewpoint now up to 41f but wind has now shifted to the NNE light.

Wow that radar down there in Richmond Kentucky Wow!! Pennsylvania Weather Radar | AccuWeather

I bet Delaware County is split in half Northern and Western Parts of Delaware County go under a Winter Storm Warning 3-5" and the east side goes Winter Weather Advisory 1-3" that would actually be a good call for around down here and let the chips fall where they may. In the mean time we have light drizzle 42.3f dewpoint up to 39f now.

This is exactly my thinking from earlier. This climo and temp wise makes total sense really. I mean I am a snow weenie but I would say yes to this.

Now to be fair the Ukie did have a foot of snow clear into South Jersey I do not think that will verify, but who knows we are in "new times".

It's sleet warm tonuge of air coming off the ocean.

Down here in Media Delaware County I am going to take these factors into mind here in Central Delaware County: 1. Temps above freezing overnight. 2. Warm ground temps. 3. elevation 4. rate dependent snows My snowfall totals in Delaware County: Media 2-4" Ridley 1-3" Newtown Square 3-6" All broughs along the Delaware River 1-2" Garnet Valley 3-5" Radnor 3-6" Havertown 2-4" Springfield 2-4" Broomall / Marple 2-4" Chester 1-2" Swarthmore 1-3" Clifton Heights 1-3" Upper Darby 1-3" Drexel Hill 1-3" Eastern Delaware County 1-2" Think I covered it.

Relax Ralph it has not happened yet. I too STILL have my doubts. We shall see currently 42.3f dewpoint 37f so we aren't close to changeover yet, but I know not to look for this prior to 5 am here.
