Mild…Then Wild? 2/26/18
Hello! I hope everyone enjoyed their weekend! Saturday started off with brilliant sunshine and mild temperatures. Unfortunately, clouds increased during the afternoon, and temperatures leveled off, making it feel a bit chilly with a brisk wind.
Sunday was a washout from morning til night. It was cold too, with temperatures remaining in the upper 30’s for most of the day. In fact, steady snow fell up in ski country, with a general 3 to 6″ of white gold!
Despite the very warm start to school vacation week, colder temperatures and periods of snow moved back into the ski resorts starting on Thursday…so all was not lost!
Even down here in southern New England, a dramatic change in the weather brought temperatures in the 70’s both TThis uesday and Wednesday, only to drop 40 degrees on Thursday with a coating to an inch of snow across much of the region!
The extreme weather changes prompted a friend of mine from New Hampshire to send me a funny message. It was Mother Nature telling New England, “You can’t squeeze all four seasons in one week.” The response from New England was, “Hold my beer!” While purely satirical, there was some truth to it!
While at a family event celebrating my nieces birthday yesterday, many family members were asking some very insightful questions. I do believe all these years of reading my blog, they’re starting to pick up on some of the topics I discuss, and are beginning to ask me some challenging questions!
My sister Pam, for example, asked me whether a warming climate is going to alter my future winter snowfall predictions, for the New England region?
Others asked me me if winter was over this year, and my thoughts for the upcoming spring and summer seasons. Wow, I need to brush up on my weather info before the next family get together!
The first question caught me a bit off guard. I never really thought of that possibility until now. This a broad, complex subject, that can be discussed by a panel of experts for hours on end. But the subject can not be avoided any longer.
The warm weather records are being smashed year after year. It was 81 degrees in Fitchburg, MA. on Wednesday! Wow! It was the first back to back 70 degree days in recorded history during the month of February in Boston!
Did anyone see the story of the 25 pound striped bass caught in the Charles River by a graduate student on Wednesday? I could go on and on, but you get the picture. It was unusually warm!
Does this mean I now believe in global warming? Have I finally caved in as a result of all the text messages my brother in law sends me about global warming? The short answer to this question is, not quite!
There’s still a resounding amount of evidence that shows these same warm spikes during winter, has occurred before. A warm day or two in February is not going to convince me.
I believe we do not have enough correct statistical proof to say one way or another. The earth has been warming and cooling naturally for billions of years. Science has proved that.
Is the earth currently warming? Current numbers say it is. But this could be as a result of increased global population, urban heat island effect, and record warm ocean temperatures.
Some climatologists believe that the weather patterns are cyclical. A lot has to do with the relationship between how much radiation we receive from the sun, and how it affects ocean temperatures. Because the sun is entering a dormant period of sun spot activity, some scientists actually believe the earth is cooling!
For those interested, I believe we will have many more answers on where our climate is headed within the next 30 rears or so. Not even a second in geological time!
Getting back to the question! I told you there’s a lot to discuss about with that subject! Yes, I actually take each year on a season by season basis. There are so many variables that go into a seasonal forecast, you can’t point out one thing and say we’re going to have more or less snow in any given season.
Was I surprised by the record warm temperatures this month. Yes, very much so. It was only a few short weeks ago I thought February was going to bring winters worst!
I told my sister yesterday that I have been disappointed in my winter forecast so far this season. She was quick to point out to me that winter does not end until March 20th, and many times winter storms can linger here in New England until the middle of April! This is all true, we always measure first flake to last!
So far, Boston stands at 35.3″” for this season. I was shocked to learn this morning that this is actually 1″ less than what we had at the same time last year! I looked across the region, and many cities and towns are in the same boat, right around average for the date, give or take a few inches.
As mentioned before, Boston’s average snowfall for any given season is approximately 44″. If we receive average snow for the rest of the season, we will actually end up around average for the season. On average, Boston receives approximately 8″ in March, and 1 inch in April.
Do I believe we are going to reach my winter prediction of between 60 and 70″ for Boston, made back in November? It’s looking like a long shot right now, but I will listen to my sister’s advice, and wait until the last flake have fallen. We’ve had snow on Mother’s Day before around here.
With that being said, I would need a big end game to pull it off. Not that it can’t happen! March and even into early April can feature some big snowstorms!
I have been eyeing the possibility of a interesting March for some time now. A developing Greenland Block is going to up the ante for possible late season excitement!
Even as we speak, high pressure is building across Greenland. When this happens, it suppresses the jet stream, deflecting it south of New England. This will allow colder air to gradually filter into New England over the next week. This evolving pattern also represents the increased possibility of a major nor’easter to strike the east coast.
One such potential threats arrives at the end of this week into the beginning of the weekend. The next threat, and looks to be even greater, arrives towards the middle to end of next week. If the Greenland Block persists into March, I still may indeed make my forecast snowfall for the winter!
In addition, this pattern developing now may delay spring from arriving too early across much of New England. Some computer models persist this block well into the spring. While others breaks it down, allowing spring to surge into the region. Very tough call here.
Right now, I do believe at least the first couple weeks of March is going to feature a couple winter weather events…perhaps significant. Thereafter, the block may relax for a time, only to reappear later in the month?
Therefore, I am calling for quite an extreme March, featuring periods of severe winter weather, with above average snowfall. This will be offset with relaxation of the pattern enough to let us know that spring is indeed on the way!
Late season snows and cold may linger into the start of April. Overall, I I believe April will be cooler and wetter than normal. The way I see it, real spring weather is going to have to wait until May to arrive this year, which will feature warmer and dryer than normal weather! Something to look forward to!
Now for your weekly outdoor winter activity forecast. I will rate this week a 4 out of 10. Possible storm at end of the week. Expect increasing sunshine for the rest of this afternoon. Much like last week, watch for another colorful sunset! It will be mild, with highs in the 40’s.
It will be clear and cool tonight, but still warmer than normal. Low temperatures will range from the 20’s across rural areas, and mid 30’s across the urban areas.
Watch for springlike weather with plenty of sun and mild temperatures for both tomorrow and Wednesday. Tomorrow will be in the lower to mid 50’s, to possibly near 60 degrees on Wednesday! Wow!
As we say goodbye to February and welcome March, watch for increasing clouds, and somewhat cooler temperatures for Thursday. If winds turn onshore, temperatures may only be in the 40’s.
The first of possible several storms will threaten New England beginning Thursday night. This storm will be tracking through the Midwest during this week. Rather than cutting into the Great Lakes, the Greenland Block will force this storm to redevelop off the New Jersey coast.
By all indications, this storm is going to intensify into a fierce ocean storm. There are a few reasons to keep a very close eye on the exact track of this storm this week for us here in New England.
First, this storm is going to be a slow mover. Second, if this storm comes close enough to our coast, there would be the threat of a major coastal flooding event. This is due to astronomical high tides, storm force northeast winds, and several successive high tide cycles. Very dangerous!
Third, rain would change to heavy wet snow, which coupled with strong winds, would present the potential for downed trees and power lines.
Right now, very latest computer models have shifted this storm ever so slightly to our south. This was enough of a shift to keep the worst effects of this storm just south of New England.
However, with the blocking high pressure to our north, this is going to be a very touchy situation, as there is a possibility of this storm appearing to be heading out to sea, only to loop back around and make a pass close to Cape Cod, before finally moving out to sea sometime on Saturday.
If this verifies, eastern Massachusetts would still be under the gun for quite a severe storm, with coastal flooding, damaging winds, and heavy wet snowfall. Future computer model guidance will let me know whether or not if that’s still a possibility.
Many are saying it’s too warm for snow. I can see that, from my experience, this storm will be so intense, it will dynamically cool the air above us, changing the rain to heavy wet snow.
At this very point, computer guidance continues to surpress this storm, keeping the worst of the storm at sea, and we would of dodged a major bullet in my opinion. Another threat will be following next week. I will be sure to update everyone sometime this week if conditions warrant.
Well, that’s about it for now! In next week’s blog, I will be looking into March in more detail. I will be closely monitoring any possibility of a major winter storm. I will also talk about some unusually winter weather occurring in Europe! In the meantime, enjoy the mild weather over the next couple days, then we’ll if the lamb or lion shows up on Friday!
Thanks for reading!
