bluewave Posted September 7, 2013 Share Posted September 7, 2013 wed - fri look very warm with wed or thu (9/11-12) potentially exceeding 90 with enough sunshine ahead of the front. Guidance doess lbring another cooldown next weekend 9/14 - 9/16 but we'll have to see if it is as cool as this weekend. Longer range it looks like the ridge builds back in by the week of the 17th with a trough into the west coast which would likely produce a stretch of above normal 9/17 - 9/21. We are in a seasonal change month. Up and downs rule The big unknown going forward into the fall will be how long the persistent +NAO pattern lasts. This is already among the most positive stretches from April to September that we have seen. The strongest blocking further north has been over the Pacific side.

psv88 Posted September 7, 2013 Share Posted September 7, 2013 50.6 here last night, great radiational cooling conditions for nassau. Any real weenies out there may be interested to note that a distinct land breeze developed along the north shore of long island last night, keep areas within 1-2 miles of the sound significantly warmer than areas just inland. A quick review of PWS all the way out notes this very clearly. Most evident is northport yaght club PWS, notes a distrinct wind shift to the S when temp plummets, and then after sunrise switches back to the north, unsurprisingly, its low was 8-10 degrees warmer than locations just a few miles inland.This extended west into nassau as well, where i bottomed out about 50, while Roslyn, right on the water, bottomed out at only 57 and the wind was blowing from the South all night, while my winds were dead calm all night long allowing for radiational cooling. At this time of year, the sound is still near 70, and with land temps dropping into the 50's, the strong temp gradient creates a persistent land breeze preventing areas along the immediate coast from radiating well.

Snow_Miser Posted September 7, 2013 Share Posted September 7, 2013 Pretty impressive trough in the medium range on the 6z GFS. Link to comment Share on other sites More sharing options...
SnoSki14 Posted September 7, 2013 Share Posted September 7, 2013 Don't see 90s with high humidity and dews, probably upper 80s tops, some warm spots coud briefly hit 90. Temperature roller coaster ride with high heat in early September to much cooler the past couple days, brief warmth tomorrow followed by more cool air on Monday, high heat midweek to maybe coolest air of the season after.

uncle W Posted September 7, 2013 Share Posted September 7, 2013 53 this morning imby...49 at the coop site near me...74 now...you can't rule out 90's still but the chances are slim... Link to comment Share on other sites More sharing options...
SACRUS Posted September 7, 2013 Share Posted September 7, 2013 ECM builds heights to +588DM with 850 temps 20(+) on wed. If we arent mostly cloudy many stations should reach or exceed 90 wed/thu ahead of the front. As others said a bit of a roller coaster with some more cool behind followed by more warmth towards the 16th. ridging into the east looks to be potentially a bit more sustained in the 9/16 - 9/21 period.

Down to 48 here this morning cooler than thu night (50). May not get much lower than 70 on wed night but by next sat we could struggle to break 70 for a high.

winterwarlock Posted September 7, 2013 Share Posted September 7, 2013 Lol sitting at the rutgers game and the sun is hot. Yes it was cool rgis morning but so what itis certainly summery now in the mid 70s Link to comment Share on other sites More sharing options...
IntenseBlizzard2014 Posted September 7, 2013 Share Posted September 7, 2013 The reason why we might see 90s return are because of two reasons: Dying MJO and steadily falling PNA. Otherwise, what's holding it back are the steadily falling NAO/AO. Link to comment Share on other sites More sharing options...
NEXtreme Posted September 7, 2013 Share Posted September 7, 2013 Lol sitting at the rutgers game and the sun is hot. Yes it was cool rgis morning but so what itis certainly summery now in the mid 70s It would feel hotter if it was actually above normal......not below....lol This is great late september early october weather as we get closer to the official start of Fall.

Isotherm Posted September 7, 2013 Share Posted September 7, 2013 Lol sitting at the rutgers game and the sun is hot. Yes it was cool rgis morning but so what itis certainly summery now in the mid 70s Of course it still feels warm, the sun angle's on par with about early April which is quite strong. Sun still making it up to about 55-60 degree above the horizon. To me your argument is akin to saying in a mid January spell of 70s, "it still feels like winter because the Sun is so weak." It's an argument based on sun angle rather than actual weather conditions (temperature, etc). Link to comment Share on other sites More sharing options...

Yeah definite torch for Wed/Thurs though I'm uncertain if we max out around 85-86 or make a run for 90. Right now I'm thinking the plume of 90F 850's gets eaten up a bit while propagating NE and we deal with a good deal of debris and mid 80s. Next weekend will probably feature a stronger cool shot than the one we just saw, at least as strong. Link to comment Share on other sites More sharing options...

bluewave Posted September 7, 2013 Share Posted September 7, 2013 The Euro looks similar to the NAM with the heat surge into the Midwest on Tuesday. Could see 95-100 range for the hotspots in places like Indiana with enough sun. The heat has been building over the Plains the last few days.

SACRUS Posted September 7, 2013 Share Posted September 7, 2013 12z ECM and other guidance continue to hone in on late summer heat surge tue - thu with heights approaching 592dm and 850 temps 18 - 20c(+). We could be looking at temps nearing records for some areas if we remain sunny enough on wed. ECM brings in strong cold front fri and 48 hour cooldown before ridge builds back. GFS/ensembles also building heights by 9/16 for an extended period through the week towards 9/20-212. it will be interesting to see how hot we can get next week (perhaps the last 90s for most) and then if next weekend could match this recent cooldown.

SnoSki14 Posted September 7, 2013 Share Posted September 7, 2013 Nothing worse than seeing 90s in September , it's like seeing 40s/50s in mid Spring, just yuck. Link to comment Share on other sites More sharing options...

If we do reach the 90s, it wont be a long wait for some more cool/fall weather next fri nigh/sat 14/15. and for those who enjoy warmer falls the cooldown looks short with more warmth by the 16/17th.

This has been well forecasted on the ecm/gfs/ensembles with strong ridge and heat blasting from the plains and GL. Guidasnce has been consistently hinting that The week of the 16th looks to be warm as well with deeper troug into the west and subsequent ridging into the east.

easternsnowman Posted September 7, 2013 Share Posted September 7, 2013 Outside of the hot spots like Newark, philly and maybe nyc I doubt we get above mid eighties. I think Md and Va have the best shot at 90, anyway this will be short it is obvious the heat for most is done. Link to comment Share on other sites More sharing options...
Isotherm Posted September 7, 2013 Share Posted September 7, 2013 The latest NAEFS for September 15th-22nd has a touch of cool probs for the SE US with generally near normal for our area. I think the front part of this period probably keeps the overall time frame cooler due to the strong Canadian shot Friday-Sunday. The 3rd week of September will likely turn progressively warmer as the NAO/AO remain in a state of transience. However, the positive PNA will keep the pattern generally back/forth temp wise the next couple weeks. As Sacrus and others have been discussing, hot shot mid this week, then the next time frame for 80s would probably by around the 18th +/- a couple days.
