ag3 Posted August 12, 2013 Share Posted August 12, 2013 The 12z Euro keeps the heaviest storms to our south tomorrow with a weak wave of LP developing on the front. It still drops .74" of rain on NYC from 6z to 18z. With the majority of it 12z to 15z. Link to comment Share on other sites More sharing options...
bluewave Posted August 12, 2013 Author Share Posted August 12, 2013 It still drops .74" of rain on NYC from 6z to 18z. With the majority of it 12z to 15z. If the low comes a little further north, we'll get into the heavy stuff. It may end up being another nowcast special once we see the actual radar tomorrow.

earthlight Posted August 12, 2013 Share Posted August 12, 2013 The RAP shows the weak low pressure developing in Central PA Tuesday morning and moving east along a warm front. The NAM also has some decent parameters between 12 and 15z as the low pressure passes nearby. I wonder if tomorrow could be a sneaky event where we see some wind damage reports and maybe the potential for some spinups along the front and near the sfc low. http://www.meteo.psu.edu/~fxg1/RUCNE_18z/f12.gif Link to comment Share on other sites More sharing options...
sutherlandfan Posted August 13, 2013 Share Posted August 13, 2013 You got to it before I did, was just going to post this. The ECMWF ensembles which saw the August cool are now beginning to see the light at the end of the tunnel w/ the retrograding WAR post 8/20. We'll have to see if the 12z ECM continues with that idea or it gets pushed back further, but over the past few weeks I've thought the last week of August would feature rapid warming in the Northeast, ultimately leading to the mean ridge position over the NE for the month of September. Long range guidance seems to suggest that right now. Even still, it's the ECMWF ensembles at 240hrs so I'd like to see another cycle or two of the WAR returning around / slightly after 8/20. Prior to that time, a significant autumnal airmass heads for the Northeast 8/13-8/17 of this week, with 850mb temps near or below +10c for most northeast of DCA. Probably going to see a couple days or more with highs remaining in the 70s and lows in the 50s for suburbia (maybe 40s for far off suburbs). NYC does worse in radiational cooling regimes so they'll probably remain in the 60s. I expect most of the Northeast to have fairly significant negative departures going into the final 10 days of August. Those negatives will come up somewhat but not enough to make August normal or above normal IMO. Seems like the 12z euro ens is already removing the Bermuda High and the heat that it brought in for the end if the month. I thought we would see a warm up going into sept over the weekend but by the looks of the 18z gfs it doesn't look like anything to get excited about. What do you guys think?

IntenseBlizzard2014 Posted August 13, 2013 Share Posted August 13, 2013 Even if there's a retrograding WAR, the Below Average Tropical activity may be difficult to break, unless the active WAR relaxes the wind shear for a large portion of the Western Atlantic Ocean.

WE GOT HIM Posted August 13, 2013 Share Posted August 13, 2013 0z 4k has a second line of strong storms coming through around 0z tomorrow - It also clears us out after the initial rain (If we could just speed things up by a few hours we could be in good shape) Link to comment Share on other sites More sharing options...
Snow_Miser Posted August 13, 2013 Share Posted August 13, 2013 Even if there's a retrograding WAR, the Below Average Tropical activity may be difficult to break, unless the active WAR relaxes the wind shear for a large portion of the Western Atlantic Ocean. The periods of the intense SAL crossing the Atlantic has been a stifling factor as well. There also has been decreased instability in the TNA as a whole. We'll see what happens and what changes in September. Link to comment Share on other sites More sharing options...

IntenseBlizzard2014 Posted August 13, 2013 Share Posted August 13, 2013 And there's a good chance it may not hit 90 this month. Probably. Although the CFS says it will and yes I mean CFS, not GFS. The CFS thinks that it'll hit 92F by August 24th (my birthday). Link to comment Share on other sites More sharing options...

nzucker Posted August 14, 2013 Share Posted August 14, 2013 What are the chances of KNYC or any of the metro reporting stations hitting 59 tomorrow night? Gonna cool and dry out quick tomorrow.Thursday might have a better chance with lighter winds... The passage of the front will ensure a brisk NW flow that downslopes NYC significantly, so I don't see 50s tomorrow night. Thursday morning is a better shot in my opinion. This should be the most significant cool shot of the month with departures around -8F depending on how cold we get at night. Averages are starting to drop at Central Park and are no longer 85/70. Models have backed off the warmth now with a more modest West Atlantic Ridge but the breakdown of the PNA/western ridge pattern should bring hotter, drier air to the East. We haven't seen a "Sonoran" heat outbreak all summer as our positive departures were all from high humidity. Link to comment Share on other sites More sharing options...
