Dare I Say, Jacket Weather Returns?
September is a wacky month, and this week will certainly show us that! The days of 80s are numbered and the days of 60s are right around the corner...closer than you'd think actually! It's a funny and expensive transition with air conditioners running during the day, and the heat on at night. So we've got good news and bad news this week.
The good news is that a cold front is moving through on Thursday, and that's helping to ensure that Tropical Storm Maria stays well out to sea. With that being said, we will have some showers and storms associated with this front.
Now, speaking of the forecast...here are some of the changes to come:
Tuesday's forecast:
80 and mostly sunny
Friday's forecast:
60 and mostly sunny
As the week progresses, high pressure makes its way down from Canada and sets up shop over the Great Lakes. This will set us up for some cool days, and even cooler nights. If things pan out how the forecast models look, we could be seeing some very cool overnight lows, and scattered first frosts of the season!
So what causes this?
In the northern hemisphere, high pressure rotates outward and clockwise. In this situation, cold air from Canada is pushed down towards us, allowing for unseasonably cool temperatures. During the day, some spots will struggle to get into the 60s, and at night, we're forecasting low temperatures to drop below 40 for a few spots across the region.
It's a losing battle for us warm weather lovers it seems...we'll be trading in the shorts for snow blowers soon enough! ![]()

With SST (sea surface temps) quite warm along the East Coast, any low pressure areas that move toward the Great Lakes (climatologically where they move toward in mid fall) will keep pulling warm/mild Atlantic air over us for some time. I would guess October 2011 and maybe even November 2011 at most NWS stations will be “above normal” temp wise once again. I should think “snow blowing weather” is at least 3 months away (if you’re lucky).
They have an old saying on the East Coast of the USA from the beaches of Newport, Rhode Island to the Virginia Capes: September and October are just a drier version of July and August – lol.

In fact, the pattern looks to turn even warmer and more humid as the Bermuda High moves a bit closer to the East Coast late next week and a southerly flow sets up along the East Coast. We should see 80 F by late next week in at least a few areas the Tri-State area. I think in the coming week the tropics and what develops or heads toward the USA mainland will be where most of the real weather drama will be.
I think overall it was a very nice summer, it was warm without being to hot, we had adequate rainfall and I didn't have to use the AC all the time unlike like last summer. But it also went really fast and I couldn't believe it when September started.
While the Tri-State area should remain modestly warm...I think you might see some frost up in New England, but only on Friday and Sat night. I know your almost a month ahead of us in southern Connecticut/Long Island, so you might see more frost by the last week of Sept. Otherwise, the pattern seems to be pretty normal in the last week of Sept/first week of October, so little truly cool/cold weather will make it south of MA.
Also, I would not be so sure about the coming pattern keeping tropical storms away from the USA - lol. The pattern will turn southerly once again by late next week (you'll even feel it up where you are), and the current disturbed area of weather off Africa right now might (if it develops) move northward off the East Coast of the USA.
Check E. Abrams blog at AccuWeather, he is even thinking a hurricane could again get close to the US East Coast.
Yes, Irene was quite a struggle for folks in the Caribbean and the USA - the last thing we need is another tropical cyclone. From the Puerto Rico to upper Maine, Irene killed 55 people (8 are still known to be missing as of today), and did from $10 to $15 billion in damage from the Caribbean to Maine.
We also had some cool temps down here (NY/NJ/CT): The 5:00 AM NWS obs this morning had New Haven down to 49 F…Groton at 47 F…and Central Park at 51 F. I don’t know if these were the lowest temps at these stations, however. My low was 47.8, so it did get a bit cool last night. However, temps seemed to rise quickly in the dry air this morning - by noon my home temp was up to 55.3 F, and the 2:00 PM obs most area stations in the Tri-State are now in the 60 to 67 F range. After this weekend the pattern looks to once again warm. In fact, as the pattern turns more southerly by the middle of next week, lows will struggle to get below 60 F, with highs in the middle/upper 70's across the Tri-State area.
Meanwhile in the tropics, the areas of disturbed weather between the Bahamas and the African coast seem to be getting better organized. This could be a player on the East Coast 7 to 10 days from now as the flow pattern turns southerly by late next week/weekend.
I have the feeling that somewhere between the coconut palms in Miami… to the beach cottages on the Rhode Island coast…the East Coast may yet again be threatened from that evil wind born in the tropical seas.
I'm very happy that WTNH has a weather forecaster who enjoys the nice, warm weather! The cold / snow bias was starting to get very old.
Glad to see your still out there!
The much hyped “cool snap” was certinaly both brief and modest; NWS Bridgeport fell to 49 F (the coldest of the last three nights), NYC fell to 51 F , and NWS Windsor Locks fell to 41 F (on the 17th). Most of the region struggled to fall below 45 F as I expected. Otherwise, the pattern will continue to warm. In fact, after tonight, lows will struggle to get below 60 F across much of the Tri-State area for the next 10 days at least. Daytime highs will be right back into the mid 70’s (80 F could be back by mid week), as a more humid pattern sets up. Sept 2011 is still running above normal at most NWS area stations across the Tri-State area.
For the cool weather fans…it looks like any truly cold weather will remain well north of us.
It has been a long summer for winter/cool weather fans; Every single month from May through September (it looks like now)has been above normal. Worse (for cold weather fans), it seems the the hot season will just will not give an inch of ground on the East Coast.
Keep in mind that just to our south, much of the subtropical Gulf/South Atlantic states still have normal highs in the 80 - 85 range. Only once we get into November or so, will the hot season finally break in the American subtropics (cities like New Orleans, Mobile, Charleston, Myrtle Beach...etc, have highs that fall below 75 F by November). So with a source of warm mild air so close to us, warm temps can occur at anytime well into October. It will be at least another month before you'll need a jacket or the furnace will click on in the Tri-State area.
For the record...NWS Central Park has had one of it's top 5 hottest July's on reacord.
Yea right, in Minnesota or Maine!
Right the East Coast is humid, green, and WARM. It’s 70 F here in New Havv. It feels no different than mid June!
Let me know when REAL fall gets here!
I think most locations between 42 and 25 latitude have really only two seasons; A cool/cold season November through early April…and a warm/hot season from late April through October.
As far as leaves changing here in the Tr-State area, still soild green here in south Connecticut. All the rain, humidity, and +70 F temps, means than the leaves will not change much for awhile.
Believe it or not it's even warmer out west, on the other side of that upper low, with very summerlike temps all the way to Montana. Last week my heat was on, now my AC is on to keep the warmth and moisture down. It looks like "island time" is back for the eastern US all the way to Canada and that doesn't look to change anytime soon. What does this mean for fall foliage? Some of the trees have started changing color in New England thanks to last week's chilly weather, but now with it being more like July for an extended period the process is slowing down. So we could be enjoying an extended period of color this year and more time for activities we normally associate with summer. It also gives the road crews in VT more time to repair the flood damage from Irene and open the roads in time for foliage traffic. So come on up to the mountains and enjoy some bonus summer weather with a little color thrown in.

However, I do think that by the middle of this week (wed or so) we’ll see a more west-southwest flow (instead of the deep southerly tropical flow we have now) and temps will come down some and humidity/dew points will fall. The first two weeks of October should see ave temps and drier conditions for much of the eastern USA. So up where you are you might again see a frost. I think locally down here in the Tri-State area, high temps should be in the 60 to 70 F range, lows near 50 F, and sunny weather the last days of September.
Hurricane Irene, heavy rain, humidity, 100 F highs, one of the hottest summers of all time in NYC, Charleston, and Miami…etc….for the winter fan the summer of 2011 will long be remembered as the summer when that old East Coast monsoon ruled with an iron fist!
After a chilly morning today (no frost in the NW Hills, however)...another prolonged bout of deep high pressure, blazing sunshine, and temps in the 75 to 85 F range will rule the Tri-State/Middle Atlantic region. The warm days and heavy rain back in September seems to have really stoped the leaves from chnaging, at least here in southern CT. The leaves are still deep green as we head into the 2nd week of October.
Looking at the coming pattern in the next 15 days - I think by late October, as temps start to cool, we should finally see some color and perhaps even a frost as we get close to early November. Otherwise, that much hyped "jacket weather" seems a long way off for much of the Tri-State area. In fact, With temps well into the 70's and even 80's...it looks like it will be another "beach weekend " for many people!
Your pissing off the winter fans...there mad it's mid October and it will be in the 70's and 80's AND THERE HAS BEEN NO FROST ACROSS THE TRI-STATE AREA (lol). I live inland and my low so far this fall has only been 39 F!!!
Poor winter fans....
The foliage down here seems to have a whitish salt spray - no doubt from Hurricane Irene, but otherwise it is still soild green in most areas. I agree, all the rain warmth seems to have pushed most areas at least 2 weks behind (even longer in southern Connecticut and Long Island). With the warm temps coming in the next five days...the several days (late next week) with tropical moisture and high humidity...I think we will see no real color until late in October at least in the Tri-State area.
As far as temps...still no frost at any of the area NWS stations and I've not had a frost in my garden(though this is not unsual - my normal first frost is around October 25th). NWS Bridgeport lowest temp is 44 F....NWS Central Park is 46 F...and NWS Windsor Locks is 35 F. The next 15 days show little chance of cold temps/frost for much of the Tri-State area. NWS Bridgeport has not had a frost since March 28th...190 days ago. With the hot weather forecasted for the next 5 days...then a wet, but mild pattern after than...I think once again many areas in the Tri-State will once again see more than 200 frost free days.This is the time of year when the lower latitude of the Tri-State area protects from early cold they get up in the Midwest or northwestern USA.
For the winter fan in the lowlands of the Tri-State area....once again it seems that warmth, green, and blazing sunshine is crushing the hope of an early and cold fall.
What an amazing weekend in New England. If you came up looking for brilliant foliage you were probably disappointed, but the weather more than made up for it. Honestly, after what felt like weeks of nothing but clouds and rain, who could complain about deep blue skies, temps pushing 80F, a gentle breeze and low humidity for three days and counting? Around here when you get a day in mid-October when you can go outside in short sleeves instead of a jacket you savor every minute of it. I had a chance to climb nearby Mt. Ascutney in VT and I don't think I've ever seen better visibility and warmth all the way to the 3100 foot summit.
It looks like we'll gradually be cooling off thru this week to near seasonal levels by next weekend. There could be rain on Thursday as the system now over Florida slowly works its way up. By next weekend it should clear up and while it will stay in the low 60s instead of 80s (it is Autumn after all) it should still be nice for the time of year.
We certainly have been on “island time” in the last few days; it hit over 80 F today at many NWS stations. We’ll see on Monday how hot it got at the different NWS sites. I took a small trip today to Rocky Neck State Beach, and there were many people enjoying the beach and surf. I went in the water and it stills feels quite warm – upper 60’s to 70 F I would guess. If this keeps up I may not have to take my annual trip to Myrtle Beach in November (lol).
I think we should watch the tropics, as I have a sense that things could get active for the East Coast late this week.
Looks to be warm again today! That's okay, I'm sure you know that I certainly am in no hurry to return to Winter.
Yes, the warmth continues. Not much sign of color here along the eastern Connecticut coast, the trees that are not green, seem to be brown from that salt spray of Hurricane Irene.
I'm thinking we'll see some more fall color the last week of so of October and maybe a frost as well.
Glad to see your getting good color up north. Here in southern Connecticut, the leaves are still about 70/30 green, and the leaves that have changed seem very dry and muted. I know our color in the Tri-State is not quite as bold as New England, but this year because of Hurricane Irene the color is really poor. Most of the trees seem to have a white-brown color to them and look shocked in a way. Add in all the broken limbs from the hurricane, and it looks pretty sad.
As far as what lies ahead as we get into late October, I think temps will come down some and be closer to normal (as of right now most area NWS stations have a mean October temp of near 60 F). There could be a big storm late next week (October 20 -22) – and while we would see rain of course down here, you might see some flakes fly up in New England. The last week of October might actually send a frost all the way south to the coast of Connecticut and Long Island (including NYC). I think I'll pick my last garden veggies for the season later this week (lol), we'll see. NWS Bridgeport, Atlantic City, and NYC have now crossed over the 200 frost free- days.
Well it looks like the storm on the 20 -22 was a bust (lol).
As we head into the last week of October – monthly mean temps are running about 4 F ABOVE NORMAL at area NWS stations (Central Park, Bridgeport, Windsor Locks, and Newark). Monthly mean temps are near 60 F (or over ) at all the area NWS stations. Also, the persistent southerly flow this fall has kept Atlantic SST quite warm. As of today, SST are still near 17/18 C (64 F) off New Jersey. In fact, as close as Ocean City, MD, SST are near 19 C (67 F).

There are finally some signs of fall here along the Connecticut coast, as some trees are changing color, others are droping some leaves, while others are still rather green. So far there has been no frost at any area NWS station. In fact, as of today, NWS Bridgeport has had 205 frost –free days (no frost since March 28th, 2011). The last frost at my station along the eastern Connecticut was also on March 28th. 205 frost free days is not too shabby for us….as 210 -220 frost –free days is the normal for NWS stations like Richmond, VA or Sacramento, CA.
Meanwhile I think the next 5 days will see more calm weather, with daytime highs in the 60’s and blazing sunshine.
Hopefully as we head towards the evil season known of as Winter, we continue to have busts as far as storms go. Speaking of Winter, I wonder what the cold weather crowd will do without their leader this Winter? LOL!!!!!
Amazing how south CT still hasn't had frost, even parts of the interior Deep South had frosts the other night. I have a friend who moved from CT to Richmond VA this summer and it's amazing how similar the weather he's getting there is to south CT.
Yes, we had a dusting of snow this past weekend right down to the coast; NWS NYC reported 2.9 inhces...Bridgeport 1.9 inhces...Groton 0.3 inches...and my station had about 1 inch. Although it melted very quickly (it's 100% gone in most of southern CT now) the weight of the snow did some tree damage as well. Added with the tree damage from Hurricane Irene, and I don't remember the last time the wooded areas of CT looked so battered.
Otherwise, the pattern looks pretty stable in the next 10 days. This week will see susnhine aand highs in the upper 50's (low 60's in some spots) and overnight lows in the 30's. Next week, a slighlty more humid and warmer pattern takes over it looks like.
