Storm sets 2 daily records;

After the mercury peaked at 54 degrees at 9:19 a.m., steadily falling temperatures turned heavy rainfall into wet, heavy snowfall by mid-afternoon. Before the storm passed, March 6 daily records of 1.78 inches of precipitation and 6 inches of snow had been set.

In all, the storm dumped 10 inches of new snow in the city and up to 14 inches in the higher elevations of Tioga and Bradford counties, according to Craig Evanego, a forecaster with the National Weather Service in State College.

12z Nam and GFS (along with 0z euro) continue to indicate a rather lengthy snow/mixed event for tomorrow, with several inches of heavy wet snow between Route 119 and I-99, continuing northeastward along 220 in NPA. This should be a big help with the flood concerns there, but further east from 522 to EPA flooding is a likelihood. Sorry guys. Hope nobody gets it bad...

I forgot the website, but does anyone know the link to see the Canadian model loop to actually see the precip type in motion for the duration of the run? Compared to its 00Z run, the CMC's 12Z run looks a tad more progressive and isn't cutting it off as much which may be a sign its starting to be more like the GFS. Let me know what the 12Z Euro show and to see if it still looks like the CMC. WAA is up which is interesting, maybe I can pick up 2" of the wet snow. I'm afraid anything over 2" of rain is going to really flood the area as the ground is completely saturated and adding to more snow melt would cause at least moderate flooding here and in places of PA.

York county..

Alright, your closest climatology sites are Harrisburg PA and Baltimore MD. Looks like your local is just about in the middle between them, so I looked up the Low Max Record for both sites.

Harrisburg, PA... (1888-Present)...

Lo Max- 83°F occurred on 8-9-1900.

Baltimore, MD... (1872-Present)

Lo Max- 83°F occurred on 6-6-1925 / 7-21-1930 / 8-5-1930.

Any thoughts on this storm mag?

Well the primary impact of this storm for everyone SHOULD be rain this go around, and the potential flooding issues that'll be coming along with it. Still questionable how severe any flooding will be. I think the threat for a widespread moderate flooding event is pretty high for folks in the southern half of PA, but temps may remain chilly enough in the northern tier where all the snow is that flooding issues could be more minor up there and the pack soaks up rain for a time. That would probably help folks along the Susuquehanna some, for if all that snow up there were torched away with all that rain it would probably result in a major flood stage for most points there and downstream. Either way, liable to be some issues of at least minor magnitude for most points area wide, in addition to probable area wide flood advisories for the urban and small stream type flooding.

The secondary-ish aspect is the snowfall potential at both the start and end of the event. Shouldn't be too impressive but the initial snow/sleet will probably dump 1-2 inches in places like JST, AOO, IPT with maybe an extra inch or so in the advised region. Wouldn't be surprised if not much at all amounted from that, but it'l'l depend on how fast things can move in. The bigger thing to keep an eye on is when the secondary develops and where a possible deform band ends up. This likely won't be anything like the magnitude of what just transpired but there could be a decent advisory or so event in store for whoever is in the right place. Right now barring a last second southeast shift it appears that the potential deform snowfall will be featured more west/nw than it was with the last storm, favoring perhaps the northwest 1/3 of PA. This has a pretty big likelihood of behaving how these rainstorm changing to snow setups normally behave... not really delivering a bunch of snow except for a lil backside in the nw and laurels. But we'll see.

There is also this snippet of Martin's writing as well... (in the aviation section even!) with a pretty decent writeup.. so CTP likely watching this pretty closely in light of the last storm which gave alot of advised and non advised counties warning totals.

A SECONDARY LOW IS EXPECTED TO DEVELOP SE OF THE MOUNTAINS BY

00Z FRIDAY...AS THE UPPER LVL TROUGH GOES NEGATIVE TILT...AS

WAS THE CASE THIS PAST SUNDAY AFT. EXPECT RAIN TO CHANGE BACK

TO SNOW...BEFORE TAPER OFF IN MOST LOCATIONS THU NIGHT. HAVE TO

WATCH SITUATION FOR THE POTENTIAL FOR HEAVY WET SNOW AGAIN.

Well batten down the hatches prepare for foul weather.

http://radar.weather...s/full_loop.php

Top map is total precip.

Bottom map is snow fall prediction. As Mag mention snow is going to be more to the north west this time.

GFS is calling for 4.06" for me

Nam is calling for 2.15" for me

Here is link for the river levels
