April outlook - will the warmth continue?

All NYC needs is to go +2.3 or greater on the month to beat MAR/APR 2010 for combined warmth.

I have to admit that after spring of 2010 that I didn't expect MAR/APR warmth to be challenged so soon.

Same. During March 2010, I was thinking that we wouldn't see something like this for decades to come, but here we are 2 years later. Let's hope this 2 year torch will reverse in a big way before 2012 is done..

2010 went on to take the title for warmest spring after May went +2.7.

Heat records seem to get broken every few years. I'm still waiting for my record cold.

Right now we're still in a period more favorable for record heat than record cold, and it'll be that way until we return to the -PDO/-AMO era of the 60s/70s, which likely is still 10 years or so down the road.

Is the Arctic as cold as it was in the 60s and 70s though? What's the point of having a mechanism to bring down air from the north if that air isn't as cold as it used to be? It's like what someone said here somewhere earlier. Despite the insane blocking the last two years, it really wasn't that cold. Just a bit below normal.

So will this Mar/Apr period be hard to beat in the years ahead is the question or will 2014 do what 2012 did to 2010. It's hard to imagine how much higher the temps can climb after what we've seen so far.

Monday, is likely to get head start from Sunday highs too. I see 90 more reachable that day. Tuesday, could be just as warm, if the cold front slows down more.

Yeah, that's a good point as well. The 18z NAM has 70 F temps at NYC at 03z Tuesday and 16c 850 temps moving towards the area. Under those conditions I would be very surprised if Newark didn't get towards 90 F

18z GFS continues to advertise 3 consecutive 80F+ days for the region; 850mb temps on Monday are very impressive for this time of year. 85 looks like a virtual lock at this point with 90 within reach.

Yeah, temps at the warmest places should push to around 90 with the Euro actually showing 16-18C 850's.

someone should definitely hit 90 on Monday, I would think. Generally that 90 threshold is met when we get 850's at about 17C or greater.. of course it depends on a lot of factors such as mixing depth, amount of sun, and wind direction, but it looks like things are in our favor to achieve maximum mixing values on Monday.

Very rare Day 2 High Risk from SPC over the Central Plains -- wow. Rarified territory.

yea, that is impressive.. if you get a high risk on day 2, you can pretty much put it in the books. This is an impressive set of upper level winds moving over that area.. 120-130 knot jet streak.. and the shear parameters that SPC is mentioning are just sick.

12z NAM still going with around 86 degrees on Monday. During the last few warm spells, it underestimated the warmth in the most favorable areas for warmth (which in mid March was New England, in this case NYC is included). Taking that into consideration I can easily see Newark getting to 90 degrees, which if it does get to 90 degrees I would assume it'd be one of the earliest 90 degree days in recorded history behind 2010.

Due south wind over Long Island. Likely mid 60s to mid 70s there.

SREF poppin' some 90s across central New England by 18z MON. Surface/UL maps looks VERY similar to 4.7.2010 when many areas had low to mid-90s, including 93F at BDL.

There's definitely a lot of similarities between Monday and 4/7/10. The main difference in the region is that 850mb temps were slightly warmer and the ridge was a bit less amplified in that case, although these minor differences would still support upper 80s and some low 90s for Monday.

Trials was a few weeks quick on the trigger, but if we see 3 days with 80-90F highs, trees will be leafing out. Current point and click has KNYC in the mid 70s Sunday, peaking in the upper 70s Monday. I think that will be blown away by at least 5-7 degrees. Could see the first 90 of the season for many spots early next week given +16c 850's, dry ground, low vegetation, and sunshine.

yeah the leaf out slowed big time, we went from about three weeks ahead to perhaps only a week ahead now. I think a couple days of 80s and mid to upper 60s to follow will cause a quick leaf out by the end of next week

It shouldn't be an either/or. I'd rather have 60s, not 20s or 80s. In other words what we should have, even a little bit above normal. 80s in the first half of April is ridiculous.

how old are you? Its quite common actually.

Temperatures in the 80's in the first half of April in the NYC area are rare. Either get a clue, familiarize yourself with some of the area's climate data, or stop posting.

You are correct that 80° days during the first half of April are infrequent in the NYC area. Statistically, an 80° day in the first half of April is 2.274 standard deviations above the mean for that timeframe (1981-2010 base) with a statistical probability of occurring on 1.15% days. However, they have occured at more than twice the statistical probability since 1981. There were 12 such days during that timeframe, half of which occurred from 2000-2011 (4/15/2002, 4/15/2003, 4/15/2006, 4/7/2010, 4/8/2010, and 4/11/2011). Perhaps better wording would have been that years in which the temperature reaches 80° at least once in the first half of April have become more common?
