Toss those sun angle arguments long and far if you have the temps and rates. and if you dont, you can still get white rain in Dec/Jan with a very low sun angle just because temps/rates were not good. Jan 2006 i was in the mid 30s with not great rates but it snowed all day and accumulated like a 1:1 inch of pure clear slush. Crazy elevation event here in CT.

Toss those sun angle arguments long and far if you have the temps and rates. And I am so sick of OCMs and other people saying before any out-of-season event, "the ground is too warm!" FALSE! Sure, at the start if the snow it is, but once intensity picks up and you get relentless phase change cooling from the melting snowflakes on the ground, the warm issue goes away very quickly! And in other parts of the country, it is even more extreme. Early Sep 1993, DEN was 92 for a high one day, and the next day they had 5" of snow. And this: 4/9/1988 Residents of Sioux City, Iowa awoke to find 2 inches of snow on the ground following a record high of 88 degrees the previous afternoon. 1 1 Link to comment Share on other sites More sharing options...

I recall one time it was -RA in CLE and the 1000-500 thickness was 525. That's impressive for lower elevations. Partial thicknesses count! Can't use the 1000-500 layer in a vacuum. 540 works best for low elevations. Link to comment Share on other sites More sharing options...

Snow that falls but doesnt accumulate, might as well be rain. hence, white rain. Link to comment Share on other sites More sharing options...

How about this? -- "noddles." They are raindrops that still have some slush left in them, and you get "cats paws" on the car windshield! Link to comment Share on other sites More sharing options...

It's all just doublespeak, plain and simple! Yes, I get the business and marketing aspect of it, but deceiving people and insulting their intelligence is not a good thing from a societal POV.

CoastalWx Posted February 16 Author Share Posted February 16 10 hours ago, The 4 Seasons said: Today (and tomorrow) is the 23rd anniversary of PDII. For that i have refreshed the maps for the event and created a new L Northeast map as well. It is Bostons #1 all time storm and BDRs #2 all time and only the 2nd time ever they reached 20" or more. 15-28" at every single climate site in OKX and BOX is impressive. Full radar/sfc loops up here: https://www.jdjweatherconsulting.com/feb-16-17-2003 A similar type storm we had on Jan 25-26th was almost on the level for SNE but id say about a couple/few inches lower on average. My area got hit hard. I was in NJ for that storm actually (was good there) but there was over 2’ in Marshfield. That 18 is spurious. 1 Link to comment Share on other sites More sharing options...

Their final PNS on Feb 19th has Marshfield 18" there is no times next to the numbers so its assumed everything is final, doesn't mean it still can't be wrong Link to comment Share on other sites More sharing options...
The 4 Seasons Posted February 17 Share Posted February 17 I just finished March 4-6th, 2001. I'm never revisiting that one ever again. What a complete mess on the PNS across all CWAs. COOP stuff is all over the place. Its a 65 hour storm so different measuring techniques caused massive differences in totals. The PNS has totals that dont make sense and end at 7AM Tue or Tue night or Wed. All the climo sites are probably wrong. BDR too high? BDL definitely too low. ORH makes sense but Will says its too low bc they stopped measuring. SWCT low totals are suspicious. etc etc. A nightmare. But i feel decent about it and increased the ranges significantly and leaned aggressive. Ironically the totals around here line up perfectly 15.5-16" I will post on March 4th. 1 Link to comment Share on other sites More sharing options...

The 4 Seasons Posted February 19 Share Posted February 19 Just finished updating the 3rd of the big 3 storms of Winter 2000-2001. This was another pita early 2000s storm with terrible PNS data and reports but not nearly as bad as Mar 2001. Didn't change all that much but now we have a new northeast view. NYC seems low and a bit odd that its a foot on the nose considering surrounding reports. Everything else seems somewhat reasonable. Was able to plug in additional reports from the Weathernet6 archive. https://www.jdjweatherconsulting.com/dec-30-31-2000 Link to comment Share on other sites More sharing options...
The 4 Seasons Posted 2 hours ago Share Posted 2 hours ago Today (and this week really) is the 16th anniversary of the mega storm of Feb 23-28th. This storm is also referred to informally as the "Snowicane". It came in two parts the first alone was a massive snowstorm for the interior and the second part separated by about 12-18hrs was a huge storm for W SNE and the Tri-State with the most bizarre and anomalous snowfall gradient ever. These two systems were really just one giant storm, a massive cut-off bowling ball just parked over the Northeast for nearly a week. Because the NWS PNS separate this into two separate events i made two snowfall maps for each, it was just easier that way but the NESIS map combines the two. If you add both together you get basically an 1888 type redux for the interior with snowfall totals in the 45-55" range for the Berkshires and Catskills. I think Slide had a total of about 51" for the event and Savoy 55.3". Ill be fixing these and replotting them but haven't got around to it yet. Here's the radar and sfc/h5 maps: https://www.jdjweatherconsulting.com/feb-23-24-2010 https://www.jdjweatherconsulting.com/feb-25-27-2010 February 23-24th, 2010 February 25-27th, 2010 NESIS combined 5-day total Link to comment Share on other sites More sharing options...
CoastalWx Posted 2 hours ago Author Share Posted 2 hours ago This was the storm that brought a blow down to SNH down to NE MA. I know everyone is focused on snow, but they had 70-90mph winds from Cape Ann to srn coastal ME. Link to comment Share on other sites More sharing options...

That snowfall gradient is probably the tightest ive ever seen with just a couple/few inches to 20-30+ over just a few miles. It's their #5 all time snowstorm at 20.9" Link to comment Share on other sites More sharing options...
SouthCoastMA Posted 1 hour ago Share Posted 1 hour ago Was that also the 32.1° wet bulb storm for many well inland, resulting in heavy rain. Could be mixing it up, but I remember there being a benchmark storm around then that left a lot to be desired Link to comment Share on other sites More sharing options...

I took this pic early on the morning of 2/24/10. Link to comment Share on other sites More sharing options...
