famartin Posted March 18, 2014 Share Posted March 18, 2014 One thing for sure the highs fail to hit freezing from 3/24-3/28. This is definite on all models right now. Two days are 22-24 F at best and the last week of March will have -25 to -30 F departures. I think we go to 5-7 F in the city three days that week for lows. -19 C at 850 and -16 C at 925 for a few days will be locks on not making freezing for 4-5 days. I do not think I am wrong with this. If that storm could trend north, a real HECS threat given pattern. I see 3/31-4/6 being seasonal and rainy with the persistent cold pattern looking to lock above 45 North for the first time in many months. Looks to get real warm south of 37 North. 50's may become more regular a few days after 3/28. Any thoughts ?? NYC has only recorded 7 sub-freezing high temperatures later than 3/24 since 1869. Most of those were before 1925. The one anomaly was the April 1982 bomb. Link to comment Share on other sites More sharing options...
IsentropicLift Posted March 18, 2014 Share Posted March 18, 2014 Well, the Canadian develops a low on the cold front for tomorrow night and brings over an inch of rain to most of the area. Link to comment Share on other sites More sharing options...

The one anomaly was the April 1982 bomb. He forgot to mention the 40" of snow we're going to get that week. One HECS to establish the cold, and another one as it departs.

DiehardFF Posted March 18, 2014 Share Posted March 18, 2014 0z CMC blows up the low OTS, 974MB. Seems like most models show a good storm in the LR. Link to comment Share on other sites More sharing options...

jm1220 Posted March 18, 2014 Share Posted March 18, 2014 GGEM looks similiar to the GFS The northern stream entity on its own can deliver for us if it's amplified and consolidated enough. We have to hope though it doesn't get sheared out like the other disturbances we've had all winter. Link to comment Share on other sites More sharing options...

LongBeachSurfFreak Posted March 18, 2014 Share Posted March 18, 2014 GGEM looks like January instead of MarchWatching the landscapers today is hilarious. They are trying to rake out beds that are frozen solid.As a landscape designer I'm not even entertaining the thought of planting till the third week In April. I would say a cold spring -3 or more departures a pretty good lock for coastal areas Link to comment Share on other sites More sharing options...

REDMK6GLI Posted March 18, 2014 Share Posted March 18, 2014 that implies our chances of anything significant are low there is like one borderline decent hint there, absolutely nothing to get excited about and being late in march next week...well this has a chance below 10% of delivering snow at the coast or near it Link to comment Share on other sites More sharing options...

Heisy Posted March 18, 2014 Share Posted March 18, 2014 Most of the GFS members are focusing on the initial wave, the 12z GFS OP actually developed a low that gave snow to PA etc on the 2nd shortwave. Some of the members show that as well. GGEM shows that scenario also. Link to comment Share on other sites More sharing options...
Zelocita Weather Posted March 18, 2014 Share Posted March 18, 2014 How does AccuWx still have 25" as the normal for NYC, If you use the most accurate number (the most data) it is ~ 29"....never understood why u would use an arbitrary very short term period to determine the long term average Link to comment Share on other sites More sharing options...

Come on dude.I know this storm might be a long shot for our area but when do we get a chance to track a big storm at the end of March that can deliver a lot of snow?

SnoSki14 Posted March 18, 2014 Share Posted March 18, 2014 Yea anything this far out is just noise but the threat for something is clearly there. The gfs still gives us snow despite the initial low moving OTS. Link to comment Share on other sites More sharing options...

Zelocita Weather Posted March 18, 2014 Share Posted March 18, 2014 They are using the official normals. What's wrong with that? I just dot understand why they make such a short period of time (last 30 years) the 'long time average'. Over time that will constantly make the long term average a moving target, when it should be nearly stationary. All that time period is picking up is a piece of a cycle. The 70-00 average was like 22" The 90-20 average could be 32" While the real answer is 29" (largest amount of data you have) Link to comment Share on other sites More sharing options...

SnoSki14 Posted March 18, 2014 Share Posted March 18, 2014 While it will probably warm up to start April I see no end to chilly shots of cold air as long as cold air hangs just to the north. It looks like the alternating +PNA/-EPO will continue. I suspect there could be some late April freezes this year. Link to comment Share on other sites More sharing options...
