May observations and discussions...

Par for the course if you ask me. This is the new normal. It's pathetic that we've recorded such insane above normal departures so many months when these departures are being compared to the warmest 30 year baseline on record (1980-2000.)

water temps in the mid 60s off the coast in late may, thats beyond rediculous.

12z NAM not really enthused on anything this afternoon.

It brings a line of convection through early tomorrow morning, around 6z.

6z is when the most shear and forcing arrives in the NYC area. Instability will be diminishing by then. Severe threat, I think, looks lower than 30%.

the obs from the nyc thicket are once again lower than the nearby airports

just look at the pictures:

I could also point out that the airports are not representative of the true surrounding climate. I've stated this before, we could probably find some problem with all observing stations given the chance.

knyc is further from reality than any other asos site in the area. notice how the winds are almost always variable

Winds are blocked there. KNYC has its uses. It represents tree lined areas of NYC better then LGA. For instance, in Bayside, a tree lined area, I'm at 82 degrees. In Astoria at my home, a more city area, I'm at 85.5.

KNYC represents certain areas well, NE Queens and the Bronx mostly, but for other areas its terrible; city like areas like Astoria, etc are better represented by LGA.

I've found the highs at LGA to not be too horribly off on average. The lows on the other hand are ridiculous. I can have a ten degree spread with them on calm clear nights and I'm only 4 miles away. Western Queens matches up with LGA much better than eastern Queens. Eastern Queens is much more green and park covered than any other area of the city except for some sections of Staten Island.

The NAM weakens the line of storms as they come through the area after 3z tonight.

The model is hitting the heavy rain potential west of the City. We may need to wait

until the 18-0z runs to be sure of the eastern extent of the heavy rain potential

tonight.

This is a good point - my only issue is that NYC is used as the center for weather in this region on most media, web radio etc.. outlets and sometimes misrepresents the extent of hot spells or seasonal extremes. An example of this are the # of 90 degree days over the last 10 years, most recently 2010 compare with other stations and the park was 10 - 15 or more lower. This kind of down plays that record season to a degree. It’s probably more nitpicking than anything else but almost 80% of the area recorded their first 90 readings yesterday and the park fell short. So the perception is we havent hit 90 yet in NYC. I cant see how today it doesnt, but lets say the park falls short again and most areas hit 90 again. You can then get to a point where the next heat spell come in June where the news is reporting first shot at 90s for the city - when in fact most areas have already hit 90 more more than once.

For us weather buffs we kind of get it - but for most regular folks they would assume it hasnt hit 90 yet and probably its not a big deal to them anyway.

Agreed with most points, but its not like KNYC was way off yesterday. KLGA hit 90 and KNYC hit 89. Very minimal in term of spread. If KLGA were several degrees higher, yesterday would have been a bigger issue. But .5 to 1 degree difference is nothing.

I agree theres not much difference in the way 89 or 90 feels anyway, its more the perception of 90 is heat.

Speaking of NYC its caught up to the surrounding sites and is at 84 now (its forecasted high)

Going forward, the euro and it's ensembles both look like normal temps. More of a flat flow with the heat confined south of DC.

Euro keeps hinting at a trough over or nearby the NE coast, GFS a bit more bullish on ridging coming east between the 5th and 7th and thereafter. Perhaps a more zonal compromise is the way to go. Both show a deep trough digging into the west in about a week and beyond.

This coming weekend may not be as friendly as the last few - looking a bit unsetteled
