Well it looks like we change to a warmer but but not necessarily drier pattern. Link to comment Share on other sites More sharing options...

True, the warmth is what I'm looking forward to. It just hasn't felt like May these last couple of weeks. Link to comment Share on other sites More sharing options...
winterwarlock Posted May 11, 2017 Share Posted May 11, 2017 The average is only around 70..low 70s..ive been in the mid 60s this week...its not that abnormal. ..not supposed to be 80 in April and May Link to comment Share on other sites More sharing options...

It's still amazing that with full sunshine in early May we only managed low to mid 60's most days. I think people also expect to go straight from 50 to 85 because that's been the case more times than not recently. You're going to be happy this time next week with a shot at 80's next Thursday and Friday before things cool off again going into the weekend.

gravitylover Posted May 11, 2017 Share Posted May 11, 2017 Re: Excessive short term rainfall rates - Twice I've been through what I would consider outrageous rainfall, once in the summer of 1989 in Cordova AK we got 11" in just a few hours. We went outside during the heaviest period and couldn't see more than a few feet. Afterwards the streets were like raging rivers and the ones that fed off the mt above town were uncrossable. There were ropes anchored to the buildings on either side of the others so you could hold on while you made your way across. It took several hours for the runoff to finally make its way to the ocean. Then there was hurricane (TS?) Floyd in Sept 1999. Here in Putnam County we got upwards of 14" of rain with nearly all of that falling in just a few hours in the afternoon. I was in the car and at one point couldn't see past the windshield, not past the end of the hood past the end of the dashboard! Driving along and it looked like I was heading into a wall so I slowed down to about 10mph and aimed the right side mirror at the ground so I could see the edge of the pavement. All of a sudden whoosh, nothing and the noise, the noise... I rolled off the edge of the road and sat there for about 5 minutes until I could see past the end of the hood again. There were cars scattered off the sides of the road that tried to drive through it and lost, the sheer volume of moving water on the road and running across it was staggering.

Floyd was actually a major hurricane at one point and then I believe cat 2 when it made landfall in North Carolina. Then the system merged with a frontal boundary and rode up the coast as a tropical storm. I'm not exactly sure how much rain we received, but we had been in a drought and the rain came down so heavily that the river reached major flood stage the next day. I also remember that a hornets nest about the size of a basketball was hanging in a tree across the street and after the storm 90% of it was gone.

You had a lot more in Hurricane Floyd than we did in Dobbs Ferry...I think about 7" fell in Southern Westchester. I do remember school being delayed the following morning, only time we had a delay for rain. Link to comment Share on other sites More sharing options...

Saturday is forecast at 53/47 here, which should be close to -10F departure. Not often you see highs in the low 50s in mid-May. I do remember a high of 46F on 5/14/10 in Westchester, that was one of the latest times we've used the heat. Link to comment Share on other sites More sharing options...

I agree, and it's especially rare seeing 50's this consistently. Saturday should be a pretty big BN day, and then we slowly start climbing back to May like weather.

NJwx85 Posted May 11, 2017 Share Posted May 11, 2017 It's amazing to see that wall of water on radar moving almost due NW to SE, although clearly it's made some Eastward progress because DC wasn't even supposed to be in the rain and it's almost too far SW now.

NJwx85 Posted May 11, 2017 Share Posted May 11, 2017 Well if this storm ends up as a bust at least the GFS keeps up hope that we won't flip back to a painfully boring Summer pattern. Storm rides right up the coast. Link to comment Share on other sites More sharing options...

I do remember school being delayed the following morning, only time we had a delay for rain. Yeah the totals were really amazing. I wasn't the least bit surprised to see the 15+ at Fahnestock St Park considering so many of the home stations nearly 1k feet below that were at 13-14". The amount of stuff that was moved around in the woods was inspiring. One hill that we rode regularly was pretty much just a growing in old work road and after the storm it had lost nearly four feet of topsoil and was washed out right down to bedrock. A little east of there in a tight spot in a canyon you could see where the water level was 15 feet up the sides on the tight corners and the sheer number of huge old trees that got washed down was incredible. 18 years later and there is still evidence of it if you know what to look for and where to look for it.

Cfa Posted May 12, 2017 Share Posted May 12, 2017 Heaviest rain I've experienced was that August 2014 event when I lived in Suffolk, I was near the bullseye. The rain was pretty loud, you could hardly hear much else, but it was soothing. But never did I expect it to amount to over a foot in 2-3 hours, it was surreal. Would've been the perfect time to have a digital rain gauge set up. Link to comment Share on other sites More sharing options...
dmillz25 Posted May 12, 2017 Share Posted May 12, 2017 I would say Irene was the heaviest rain I've experienced. over 8" in 12 hrs. Last Fridays rates was one of the heaviest I've experienced as well Link to comment Share on other sites More sharing options...
