ChescoWx Posted February 14, 2014 Share Posted February 14, 2014 With yesterday's 20.0" of snow/IP/ZR here in NW Chester County which melted down to 2.08" we have now had 33.1" of snow so far this month and with the 1.69" that of ZR that fell on 5th we now have in the current 25" snow depth 5.52" of water equivalent. We have already had 9.02" of water equivalent precipitation this year here in NW Chesco. I keep telling my wife....who is so fed up with this weather I can't begin to tell you....that it will be a great spring for the lawn...plenty of water and great protection from the cold. We have now had 25 consecutive days of snow cover plus since December 8th a span of 68 days we have had 44 days with snow cover. With the current glacier in place and with a couple more snow and ice events this week my Wxsim module still shows 20" of snow on the ground at 5pm this coming Thursday...plus by that point it is growing increasingly likely that we will once again see another cold stretch in the near future. I am pretty sure we will have at least one more significant snow event (over 6" here in NW Chesco) before winter finally gives way to what we all hope is a much deserved great spring! I have a new driver and am looking forward to chasing the little white ball later next month....although if it was Tony he will no doubt be out there soon with a little orange ball!

JCT777 Posted February 14, 2014 Share Posted February 14, 2014 Yeah, lots of liquid in that snow pack. Hoping for no 55 degree+ rainstorms any time soon. Once the transition to spring occurs, I'm anxious to get back on the tennis courts. Link to comment Share on other sites More sharing options...
windvane Posted February 15, 2014 Share Posted February 15, 2014 I just hope it is a real slow snow melt or a 60+ 2 inch rainfall for eastern pa will result in record flooding Link to comment Share on other sites More sharing options...

Interesting, thanks. My only question is whether you have subtracted out from your snow cover the mass of snowpack (liquid equivalent) that has either melted and run off/evaporated or sublimated directly. I would think at least 1/3 of it has, despite the very cold temps. I know the 3" of snow I received in part 2 very early Friday morning was completely melted by Friday night.

RU848789 Posted February 16, 2014 Share Posted February 16, 2014 I dont know if you saw this map. 1780615_728465647186836_1642609230_n.png Cool map, but I have to ask, what is the rationale for what areas were included vs. not and what do the little areas represent (they're obviously not counties)? Just curious... Link to comment Share on other sites More sharing options...
chubbs Posted February 16, 2014 Share Posted February 16, 2014 MA snow water content map. Hard to read but looks like 2-4 from 295 N+W and 4+ iscattered n far NW suburbs and LV. In good agreement with Tony's map. Link to comment Share on other sites More sharing options...
hazwoper Posted February 16, 2014 Share Posted February 16, 2014 RU I cannot answer the rationale question, but I am fairly certain the the little areas are drainage basins, broken down into subsections for flood management purposes. Perhaps even broken out by individual creek watersheds (neshaminy, pennypack, etc.). Hard to tell. Link to comment Share on other sites More sharing options...
KamuSnow Posted February 17, 2014 Share Posted February 17, 2014 Has anyone seen anything regarding amounts of potential rainfall later this week? I'm guessing if it's an inch or less, this will take a bite out of the snowpack but not put us at risk for major flooding. Link to comment Share on other sites More sharing options...

An incredibly difficult forecast which I'm glad I don't have to officially make. Warm rain on snow is the fastest way to melt it. Link to comment Share on other sites More sharing options...

I remember the 6" here on Jan. 2nd (with temps below freezing until Sunday afternoon of the 5th) disappeared overnight on Jan. 5th - 6th in the warm rain. The "snowpack" was all powder, but still.

The "snowpack" was all powder, but still. The "saving grace", to be sure, is that it takes longer to melt a glacier, but there's still way more water in it than your "average" snow pack, so slower melting by depth lost would still release water at a fairly fast rate.

Because I enjoy snow I wouldn't mind seeing the snowpack hang around (and be added to), yet it's a pretty safe bet that by mid March or the end of March it will be a memory. A gradual meltoff would be ideal, I don't know how likely (or not) that will be. Link to comment Share on other sites More sharing options...
Rainshadow Posted February 21, 2014 Share Posted February 21, 2014 Cool map, but I have to ask, what is the rationale for what areas were included vs. not and what do the little areas represent (they're obviously not counties)? Just curious... RU848789, I think this map was generated by MARFC because it includes river basins that have forecast points in them. Sorry for the delayed response, finally got a day off.

Mitchell Gaines Posted February 22, 2014 Share Posted February 22, 2014 The water in the snow is still about the same even though the depth decreased some at Allentown yesterday. Link to comment Share on other sites More sharing options...
