After all the tree damage from Irene that was a disaster and brought down so much more. Schools were closed for days because it was sketchy for the buses to get out, we had no power for about a week (after having no power for 5 days after Irene) and the town banned trick or treating because branches were still hanging and streets were narrow from all the debris. I had a huge old maple on my roof for almost 3 weeks until we could get a tree guy to come cut it up and not ruin the roof that was just reshingled a month prior. The next year the snowstorm after Sandy wasn't quite as devastating but again, no power and schools were out and the town cancelled trick or treating.

I drove home from work in the city and was dodging trees and branches all the way up the Sprain Brook and Taconic Parkways. That was one of the scariest rides I've ever taken.

Icon has pretty much the same type of system we had today for this weekend. It’s kinda funny cause we had a rain storm than a dried out cold front and than the wave developed along the front and produced today, icon literally has an identical pattern for the rest of the week i don’t think icon does well but it did perfect with this past snowstorm it didn’t budge what so ever the whole entire time Link to comment Share on other sites More sharing options...

donsutherland1 Posted April 3, 2018 Share Posted April 3, 2018 The snow from yesterday's snowstorm is rapidly melting. By the end of tomorrow, it will likely be all but a memory. Nevertheless, the pattern remains one in which the potential for an additional measurable snowfall is higher than climatologically normal. This weekend poses one such threat, but there is a possibility that this system could track too far to the south to bring such snow to the region. Select seasonal amounts through April 5 are: Bridgeport: 45.9”, 19.1” above normal Islip: 65.9”, 41.6” above normal New York City: 40.9”, 15.6” above normal Newark: 39.4”, 11.7” above normal Before colder air returns later this week, a more springlike air mass will move into the region ahead of a strong cold front. Temperatures will rise into the 40s today and then spike into the 60s tomorrow. Parts of central New Jersey could approach or reach 70° tomorrow. Today will likely see periods of rain. Tomorrow could see a thunderstorm as the cold front pushes eastward. Finally, in the extended range, the EPS is signaling a possible break in the generally colder than normal pattern as mid-month approaches. New York City’s Average Temperature Through: 4/2 44.8° (3.2° below normal) 4/5 43.2°-46.8° (4/2 estimate: 45.2°-48.8°) 4/10 42.7°-47.8° (4/2 estimate: 44.0°-48.8°) Per aggressive sensitivity analysis, the estimated probability of an below normal monthly anomaly: 53% (4/2 estimate: 52%) New York City April Snowfall Climatology: 1869-2018: Updated for Yesterday’s Snowstorm Days with measurable snowfall: 60 Days with 0.5" or more snowfall: 44 Days with 1" or more snowfall: 30 Days with 2" or more snowfall: 21 Days with 3" or more snowfall: 14 Days with 4" or more snowfall: 10 Days with 5" or more snowfall: 8 Days with 6" or more snowfall: 6 Days with 7" or more snowfall: 4 Days with 8" or more snowfall: 4 Days with 9" or more snowfall: 2 Days with 10" or more snowfall: 1 Years with 1 or more days with measurable snowfall: 43 Years with 2 or more days with measurable snowfall: 13 Years with 3 or more days with measurable snowfall: 3 Years with 4 or more days with measurable snowfall: 1 Most days with measurable snowfall: 4, 1875 Highest daily snowfall: 10.0", April 3, 1915 Biggest April snowstorm: 10.2", April 3-4, 1915 Distribution of Days with Measurable Snowfall: April 1-10: 29 (48%) April 11-20: 28 (47%) April 21-30: 3 (5%) Latest measurable snowfall: April 29, 1874 (0.5") Most recent April measurable snowfall: April 2, 2018 (5.5") Monthly Snowfall Totals for April: 1.0” or more: 22 months 2.0” or more: 17 months 3.0” or more: 12 months 4.0” or more: 11 months 5.0” or more: 9 months 6.0” or more: 5 months 7.0” or more: 4 months 8.0” or more: 4 months 9.0” or more: 3 months 10.0” or more: 2 months 11.0” or more: 1 month 12.0” or more: 1 month Snowiest April: 13.5”, 1875 Link to comment Share on other sites More sharing options...

Actually there was at least a couple of inches at various times in Manhattan during that storm that were subsequently washed away, when the precip would go from heavy rain to heavy snow back and forth during most of the event. There was most likely a max depth of 2-3 inches at some point in Central Park that was never recorded, what a shock. Events like the April 9-10 and of course the January 1996 blizzard, recorded as a ridiculous 20.2 inches in Central Park when anyone paying attention at that time recorded anywhere from 24-26 inches in Central Park, some even say 28, is why KNYC did not get in the 80-85 range which would have been a better representation of that winter rather than the official 75.6 record.

You are correct. 4/9-10 had 0.7" in Central Park. The error was mine, as I accidentally looked at 4/7-8 when posting the numbers. Link to comment Share on other sites More sharing options...
