Frost on The Pumpkin! 10/30/23
Hello! I hope everyone enjoyed their weekend! Once again, we couldn’t get through a weekend without rain. This would make it 17 out of the last 20 weekends which featured rain! Mother Nature is sure squaring up the score compared to last year. If you recall, last year we experienced the complete opposite pattern, with 17 out of 20 dry weekends with no rain! As we move deeper into the season, the changes become more extreme. Saturday, much of New England basked in summertime temperatures! Boston tied a record for the date with a high temperature of 81 degrees! People were flocking to the beach and parks to enjoy one last fling of summertime warmth. As we all dreamed of possibly more summer like weather on the way for Sunday, a subtle cold front slipped through New England overnight Saturday, whisking summer away.
As we awoke on Sunday, the reality of the time of year and living in New England settled in. Northeast winds plummeted temperatures some 30 degrees colder than just the previous day. In addition, rain overspread the region from west to east, leading to a very raw, wet Sunday afternoon. It was a great day to spend indoors with friends & family by a fire! In fact, temperatures cooled so low, rain turned to wet snow in central & northern Maine away from the coast! Hard to believe, these areas experienced their first snowfall of the season, with some locations receiving 3 to 6″ of snow!
Snow in this part of New England is not uncommon this time of year. Much of northern Maine extends up into Canada, anyway. Therefore, cold temperatures and some snow is not unusual around Halloween. However, after such a warm stretch of weather, it was a surprise how quickly the seasons changed. Not to be left out, some parts of northern New Hampshire is also seeing their first snow of the young season!
Indeed, with the dramatic shift in temperatures, we are inching closer to winter! So far, this fall has been warmer than normal. Not record warm, but consistently warmer than average, especially nighttime lows. In fact, it still hasn’t fallen below 40 degrees in Boston. Many areas within I495 have not reported a frost as of yet. This is some 3 weeks behind schedule. However, I did receive a report from my sister Pam in the seacoast region of New Hampshire of their first frost of the season last Tuesday morning, the 24th!
Typically, peak fall foliage would be settling into Boston this week. While taking a quick drive around the area yesterday, fall foliage appeared to have awakened at the last minute! As expected, colors are not as vivid as some past years, but there are still pockets of beautiful colors to be had! It seems some trees have tolerated the excessive rainfall this past summer better than others. The red maples don’t seem as vibrant, but the yellows and oranges have some pop. We shall see. I have seen vibrant color appear out of nowhere at the last second. With frost coming this week, we could have a secondary peak this upcoming weekend as the cold eases. Despite not having any real cold nights this October, it seems temperatures were just cool enough to initiate the color change. It’s not too late in the city right through the first 10 days of November we can enjoy peak fall colors!
As I mentioned earlier, this autumn has been above average so far in much of New England. However, we still have November to go through to determine the three month average of September, October and November. November is a true transition month to winter. It’s similar to May being the seasonal transition month to summer. We all know how May can be! Some years, May can be very summer-like, with warm temperatures and early trips to the beach. However, other years, May can be cruel, with damp cold ocean winds.
November is similar. Some Novembers are sunny and warm. Just last year November featured endless days of Indian Summer. The month ended much warmer than normal with hardly any wintry weather to be found. This, in my opinion, set the tone for the winter. If you recall, Boston experienced one of its warmest and lest snowiest winters on record last year. I believe it was the second warmest, and 3rd least amount of snow. If you enjoy winter, it was a total bust! With it being a La Nina year, inland areas did better, but we’re talking well north and west of I495 & beyond. Otherwise, most storms were rain along the coast last winter.
Other years, November can turn quite wintry. It typically doesn’t snow much in Boston during November. However, about once every five years, the city does receive a wintry type storm. It’s not unprecedented to see a half a foot of snow some years across inland parts of Boston. Logan airport averages approximately 1.5″ of snow in November. Mild ocean temperatures can protect the immediate coastline from substantial snow in November. Inland locations can see more snow, being further away from the influence of the mild ocean. Most of November is typically not harsh. However, starting around Thanksgiving, winter can make its presence felt around here. Up north and higher terrain, winter weather is more common than not in November.
After a string of mild Novembers, I believe this November is going to be different. A cold front will move through New England tomorrow, on Halloween. This will prevent temperatures from warming up tomorrow. I will have my trick or treat forecast shortly. Temperatures will drop tomorrow night, with many locations falling to near 32 degrees or below by Wednesday morning. A storm will be developing at sea on Wednesday. Had this storm tracked closer to the coast, the potential would of been there for a real mess on Wednesday, even close to Boston! Latest indications are taking tracking this storm more easterly than northeast. This will keep the heaviest moisture east of us out to sea. However, there will be some upper level energy crossing the region on Wednesday. It wouldn’t shock me if some of us saw some wet snowflakes mixed with rain showers at some point Wednesday!
Overall, November is looking quite chilly to me. There will be some mild periods as there most often is. However, temperatures will be decidedly colder this November, than previous years. In addition, I’m expecting an active storm track near New England. This leads to the question, will we see snow this November in Boston? I’m very confident there is going to be one or two wintry events this year. As always, inland locations favor frozen precipitation. However, even here in Boston and along the coast, I do believe we have a higher than average chance at seeing some snow this November. Maybe even a couple inches.
Computer models have been hinting of a storm threat between November 7th and 10th. I can see on the weather charts the potential is there for an early season nor’easter. This does not mean all snow in Boston, but I can see interior locations such as the higher terrain of Worcester County receiving their first snowfall of the season. Even in Boston, if the storm takes the right track, there could be some snow as the storm departs and cold air wraps into the system. Thereafter, colder than normal temperatures should prevail for most of the month, with other opportunities for wintry precipitation.
This sudden pattern change has caught my attention. My official winter forecast won’t be posted until November 20th next month. However, I can tell you from now we are seeing certain atmospheric conditions setting up that has either never been observed before, or hasn’t in a very long time. Many signals are opposite from what they were last year. This could mean a much more snowier and colder winter on tap for us here in New England this year. They say we’re in a strong El Nino, but I have to tell you, the atmosphere is not responding in typical strong El Nino patterns. We’ve had nearly 20 named storms in the Atlantic basin this year. Absolutely unheard of in a strong El Nino. Strong El Nino’s prohibit tropical storm development due to strong westerly winds aloft, resulting in shearing thunderstorm development.
Changes in the Pacific Ocean temperatures can mean more cold air building across eastern Canada this year and spilling into New England than one would normally expect in a strong El Nino. It does appear as if there will be an active sub-tropical jet stream this winter tracking storms along the Gulf coast then up the eastern seaboard. This type of storm track could evolve into quite a stormy winter. The big question right now is if there will be enough cold air available as these storm track up the coast to produce snow. Last post I mentioned I was leaning towards a mild but snowier than last winter, but still below normal average in Boston. Now, I’m not too sure about that preliminary prediction. The potential is there for an old fashioned New England winter, with substantial snow. How much is yet to be determined. I will update everyone in my next post two weeks from today, and have my official winter forecast posted on November 20th. Stay tuned!
Just a quick weather history segment. It was three years ago today the region observed the first substantial snowfall of the season. In fact, it was a record snowfall for Boston, with between 4 and 6″ of snow falling across the city. Hard to believe we had to break out the shovels and plows the day before Halloween! We can see snow some years around Halloween, but many times it’s very wet and melts on contact. Not this storm. Very cold air was associated with this storm, and temperatures plummeted into the 20’s as the snow began to fall heavily. This allowed the snow to rapidly accumulate. There was little wind associated with the storm, so power outages and downed trees were minimal. I remember lots of snow clinging to the trees, which still had their leaves on them. Very cold temperatures persisted into Halloween the next day, with snow remaining on the ground, especially in shaded areas. Strangely, we seem to have snow in the forecast around Halloween more than Christmas time around here in recent years!
Now for your weekly autumn outdoor activity forecast. I will rate this week a 7 out of 10.
Well, today was another washout. No surprises there, just to expect the rain to dwindle overnight with leftover fog and drizzle. Later at night, skies will begin to clear. Low temperatures will mainly fall into the 40’s region wide. Leftover snow way up north will also slowly taper off. I’m sure it will be a winter wonderland when dawn breaks tomorrow in that region!
Halloween will feature some early morning clouds. These clouds will diminish yielding mostly sunny skies for the balance of the day. Temperatures will not respond, as cold air will be pressing in from the north. High temperatures will only be around 50 in Boston, but may not make it out of the 40’s across the Worcester hills. Halloween night will feature chilly to cold conditions. Trick or treat! Expect mainly clear skies and temperatures quickly falling into the 40’s, then 30’s after 9:00 pm. Temperatures will fall into the 20’s and low 30’s region wide by Wednesday morning. The only thing that may keep us a little warmer if some clouds show up earlier than expected.
Wednesday should feature more clouds than tomorrow. Happy November! As I mentioned earlier, a storm will miss us heading out to sea. However, some leftover upper level energy will need to spin through our region during the day. This may lead to some instability showers of rain or snow, depending upon your location! No accumulation is expected with this activity if by chance you see some snowflakes. It will be cold, with highs mainly in the 40’s.
I’m expecting clearing and cold weather Wednesday night, with many locations receiving a hard freeze, and the end of the growing season. If it doesn’t happen tomorrow night, it will Wednesday night, early Thursday morning. Temperatures should fall into the 20’s region wide, even the potential of a few upper teens in normally colder locations. Even Logan airport could drop to 32 degrees, which would be a few days ahead of average.
Cool weather will continue on Thursday, though temperatures should moderate back up close to 50 under mainly dry conditions.
A slight moderation under dry conditions will commence on Friday and may continue through the upcoming weekend. Temperatures will slowly warm up to the mid 50’s on Friday, then lower 60’s both Saturday and Sunday. Conditions should mainly be dry. However, an approaching cold front may mean some showers approaching by late Sunday. Not sure about that just yet. Next week could get interesting as I mentioned above. It looks colder, and perhaps turning stormy?
As a reminder, daylight savings time ends this Saturday night, November 4th. Time to turn the clocks back one hour!
Well, that’s about it for today! My next post is scheduled two weeks from today on November 13th. However, if any type of winter storm threatens, I will be sure to update everyone a week from today. If no update, there will be no storm. In my next scheduled post, I will reveal more details on my upcoming winter forecast. I will also discuss how this winter may compare to past winters. I will also have a new weekly forecast. In the meantime, no need for snow shovels this Halloween, but break out the heavy jackets & winter coats! Enjoy!
~Wishing everyone a safe and Happy Halloween!~
Thanks for reading!
