[North Balti Zen]

My son saw a few flakes around 9:30 pm - matches timeframe from NW balt and Wxusaf obs...

[Herb@MAWS]

32.4 the low so far overnight, but up to 32.9 at 6am Wednesday.

Snow flurries Tuesday night around 9-9:30pm.

[dailylurker]

35 degrees here in the tropical rainforest. At this rate I might not see a freeze this winter lol

[H2O]

I might be able to radiate some more but was 34.5F when I got up 

[mappy]

34 with virga overhead. womp womp

[WxUSAF]

Got to 32 briefly. BWI going to need an interhour if it got there. 

[WxUSAF]

RIC down to 29!

[MN Transplant]

33.8 was my low.  DCA didn’t have an ob below 37.  First freeze in December?

[CAPE]

34 again this morning.

First freeze tonight maybe. Forecast low of 26. I'll take the over.

[BlizzardNole]

My little warm spot got to 33.  I checked my tropical milkweeds and lantanas and they live another day, which confirms it (they die instantly at 32).  It's funny how this spot is one of the last in the area to freeze, even compared to Gaithersburg.  Wow at Staunton reporting 22! 

I think tonight is the night though as my point/click has low of 26.  I will go with 30.

Yeah, Staunton (and the valley area around) went calm on the winds around 10 pm last night and you can see their temps go down from there. My winds stayed up until around 4 am, and I only dropped to 28.7 here, plus my clouds never really cleared out. But the clouds cleared/broke up in last hour, sunny here now.

I tried to transplant my latannas into a larger pot to keep in the garage over the winter.   Well, didn't work.  I m ust have shocked them, even thought I made sure they had enough water.  Probably distressed them.

Nope, only 33 at BWI

Next summer I am going to try a few in large pots, then bring them in for the winter.  I love those plants -- flower all the way until freeze, low maintenance, butterflies and hummingbirds, and most importantly, our hordes of rabbits and deer won't touch it.

Looks like we got a nice weekend incoming!

that was my plan.  I did it yesterday morning before i hopped online for work and probably compacted the roots.  They dried up, and i put the pots in totes so I could overfill them, but it isn't really helping.  Need to do a better job next year.   I also took two larger Vincas in as well, but they seem to be fine. 

 

I've garage kept two palm trees over the past 3 winters and they are still thriving.

Rapidly warming SSTs off our coast go together with the record 500mb ridging that we have been experiencing.

Most of us are familiar with heat waves on land, but in a warming world, heat waves are starting to become common in the ocean, too. One basin in particular, the normally cool Gulf of Maine in the Northwest Atlantic Ocean, has seen several heat waves in recent years and has spent most of 2018 with unusually warm water temperatures.

On August 8, 2018, scientists using satellite data and sea-based sensors measured the second warmest sea surface temperatures ever observed in the Gulf of Maine. Average water temperatures reached 20.52 degrees Celsius (68.93 degrees Fahrenheit) that day, just 0.03°C (0.05°F) below the record set in 2012.

The maps on this page show sea surface temperature anomalies as compiled by NOAA’s Coral Reef Watch, which blends observations from the Suomi NPP, MTSAT, Meteosat, and GOES satellites and from computer models. Shades of red and blue indicate how much water temperatures were above or below the long-term average for the region. The map above shows conditions on August 8, the near-record setting day, while the map below shows conditions across the entire month of August 2018.

The heatwave of 2018 fits with a much longer trend in the region, which is among the fastest-warming parts of the global ocean. In the past three decades, the Gulf of Maine has warmed by 0.06°C (0.11°F) per year, three times faster than the global average. Over the past 15 years, the basin has warmed at seven times the global average. The Gulf has warmed faster than 99 percent of the global ocean.

 August 1 - 31, 2018

“We’ve set 10 daily temperature records this summer, after setting 18 this winter,” said Andrew Pershing, chief scientist of the Gulf of Maine Research Institute (GMRI). “We’ve had to add new colors to our temperature illustrations to reflect just how warm the Gulf of Maine has been this year.”

In recent years, oceanographers have come to define marine heatwaves as periods when water temperature rise above the 90th percentile (of average temperatures) for more than five days. In 2018, the Gulf of Maine has spent more than 180 days above the 90th percentile.

The Gulf of Maine stretches from Cape Cod to Nova Scotia, and it is key intersection between cold water masses from the Arctic and warm water masses from the Gulf Stream. The warming trend in this basin likely has two main causes. First is the overall warming of the global ocean as air temperatures and greenhouse gas concentrations rise. Second is the melting of ice in Greenland and the Arctic Ocean, which provides pulses of fresh water that can alter ocean circulation patterns in the region.

“We are seeing a major shift in the circulation in the North Atlantic, likely related to a weakening Atlantic Meridional Overturning Circulation (AMOC),” said Pershing. “One of the side effects of a weaker AMOC is that the Gulf Stream shifts northward and the cold current flowing into the Gulf of Maine gets weaker. This means we get more warmer water pushing into the Gulf.”

“Climate change is likely contributing to the circulation changes through melting in Greenland and the Arctic,” he added, “as well as making long-stretches of warm weather more likely.”

The warming waters are already affecting marine species in the area, according to several news media and scientist accounts. Herring populations (based on fishing catches) seem to be down this year, and researchers and fishermen are seeing more species usually found in warmer waters, such as butterfish and squid. The populations of copepods, a key food source for endangered Northern Right Whales, also seem to be moving with the changing conditions. And puffins have had to adapt in feeding their chicks this year, as the newly common butterfish are too large for hatchlings to swallow.

I love surf fishing. Starting in the early 2000s, I would catch Southern Kingfish in Ocean City, NJ. At first it was rare and only if the water was warm during the height of summer. Now, they're everywhere and can be caught as early as Memorial Day and as late as Columbus Day. Stripers in NJ leave earlier and earlier each spring and it's a shame. Our oceans are warming and no one seems to care.

My neighbor videoed the flurries last night and posted it on FB so it counts! 
 

Two traces of snow already! Big winter inbound!

[WinterWxLuvr]

If this wind dies, it’s going low tonight

[JakkelWx]

42/18. I think we're going to freeze hard as soon as the sun goes down

[WinterWxLuvr]

I think it’ll be in the 20’s here by 9 pm. That might be a bit ambitious but we’ll see.

[WxUSAF]

Running 5F colder here than this time yesterday 

[WinterWxLuvr]

Forecast to make a run at the teens. That’s chilly

[CAPE]

High of 42 here. Currently 38.

[CAPE]

Down to 34 at 6pm. That ties the lowest temp here so far this fall.

[midatlanticweather]

Already hit 32.2. It will be a cold night! 

[JakkelWx]

Down to 33/21

I see some PWS's in northern NY adirondacks in the single digits

[WinterWxLuvr]

32 at KOKV

[WxUSAF]

5 nearest PWSs on wunderground: 28, 31, 32, 35, 35

[CAPE]

Just hit 32 here at 730.

eta- 30.5 at 8pm. First legit freeze. Radiating well here.
