A-L-E-X Posted July 21, 2011 Share Posted July 21, 2011 Actually last summer there weren't many 88's and 89's in the park. In years past, most heat waves started with a day at 88; last year didn't. Tony kept track of the number of days with 88 and 89 degree highs at NYC and they were 2x-3x as many as any other location. NYC had the same number of 90 degree days as JFK and less 95 degree and 100 degree days-- which is hard to explain lol. Link to comment Share on other sites More sharing options...
A-L-E-X Posted July 21, 2011 Share Posted July 21, 2011 0z NAM looks like near 100 Sat and mid to upper 80s by 12z Sun to start the day! Wow, what does it have for a high on Sunday? NW winds Saturday and Sunday? Link to comment Share on other sites More sharing options...
ArtRosen Posted July 21, 2011 Share Posted July 21, 2011 76 in the city right now... wondering how the heck we're gonna get to 100. Link to comment Share on other sites More sharing options...
earthlight Posted July 21, 2011 Share Posted July 21, 2011 NAM MOS now flipped EWR and LGA..with EWR 102 and LGA 103..but I think we get the picture..this is going to be a big heat day on Friday. Link to comment Share on other sites More sharing options...
earthlight Posted July 21, 2011 Share Posted July 21, 2011 The advection of the big heat is timed with the lowering dew points and it saves this from being downright insane....if you look at the MOS you can see it well. At 15z Friday LGA is 94-74...and at 18z they are 100-103/70. So the dew points drop enough to keep heat index values below 110. Link to comment Share on other sites More sharing options...
earthlight Posted July 21, 2011 Share Posted July 21, 2011 This is working in conjunction with the west-northwest flow as opposed to the southwest flow which was advecting in the higher dew points...the wind shift moves south and the dew points lower as the west-northwest downsloping winds kick in. On the NAM this occurs in the morning to early afternoon Friday. At 09z you can see the wind shift in Northern PA but a moist southwest flow still in place over our region. http://www.meteo.psu.edu/~gadomski/ETAPA_0z/f33.gif By 15z the entire area has a drier northwest flow. http://www.meteo.psu.edu/~gadomski/ETAPA_0z/f39.gif The 12z MOS were picking up on this too...notice the drop in dew points between 48 and 54 hrs (12 and 18z friday at that time) http://www.meteo.psu.edu/~gadomski/COMPMOSDEW_12z/mosloopnew.html This should save this from being unbelievable unbearable as some of the guidance was showing the other day with 78 F dew points and 100+ degree surface temperatures.

Good, this increases the chances of it getting to 100 here and no sea breeze. I want the lower dewpoints that come in with a land breeze so its easier to get to triple digits. This is good news if you want higher actual temperatures throughout the region A WNW flow has been the theme all summer-- no reason for it to stop now lol. This is just like when in the winter, a certain pattern sets up and keeps repeating itself over and over again; this reminds me of some of our snowy winters when we werent sure what form the precip would take or whether it would make it all the way up the coast, but the pattern kept repeating itself and it almost always did.

Last year there were a dozen or more, this year they are starting to pile up. Link to comment Share on other sites More sharing options...
Weathergun Posted July 21, 2011 Share Posted July 21, 2011 I think saturday turns out much hoter than the 92 forecasted by me with a downsloping NW wind The 6z NAM and GFS are showing a south wind Sat afternoon for JFK But they also show winds switch to NW Friday afternoon and lower dewpoints. So I think JFK will probably hit 100 tomorrow. Link to comment Share on other sites More sharing options...

BlizzardWarning Posted July 21, 2011 Share Posted July 21, 2011 we are going to need a big jump quick to get into the upper 90s today Mid to Upper 90s is a sure outcome at this point for most people in the City and west of the Hudson. However, Howard Beach might only top out in the Mid-90s. Link to comment Share on other sites More sharing options...
