Benign weather continues…11/19/12
After a couple of intense storms battering the mid-atlantic and New England region this fall, Mother Nature has pulled back off the gas pedal here in mid-November. According to computer models from last week, we should of been gearing up for our third major nor’easter to strike us. As it turns out, the storm is developing, however the track of it will be more towards the east rather than up the coast. This is a good thing. With all of the chilly air hanging around lately, undoubtebly, this storm would of carried its share of high winds, coastal flooding, heavy rain, and even heavy wet snow. With this being the busiest travel weeks of the year, this should come as a relief for all those traveling over the hills to Grandma’s house. I will have my complete Thanksgiving week forecast at the end of this blog.
We are now a little more than half way through the month of November, and it’s time to reviewing what the weather has been like, and what we can expect for the remainder of the month. As I have been saying, November is the critical month that I use, in determining what kind of a winter we should expect here in New England for the upcoming winter. There are many other things I look at, but the temperature and precipitation patterns during the month is the number one signal.
So, how have we been doing? Well so far, it has been an interesting month. As predicted, it has been a much cooler November this year compared to last. How much you ask? Temperatures have been averaging about two degress below average. At one point, they were as much as five degrees below earlier in the month. Last year, November turned out to be the warmest November on record, and we all know how warm the winter turned out. Looking out over the next two weeks, I see temperatures which are going to be all over the place. It looks like there will be brief warm-ups followed by cold shots of air. If you add all this up, I believe November will come in at very close to, if not slightly below average.
How about precipitation? So far, despite what you may think, it has been a very dry year in Boston. We actually are running nearly 8″ below the average for the year! Part of this should be blamed upon the record dry and warm winter of last year. Despite the two significant storms this fall, we are still running dryer than normal. This trend has continued into November, where we are running dryer than normal for the month. November is typically one of our wettest months of the year!
So what does this mean for the upcoming winter? This is two conflicting signals going on here. Yes, the temperatures may signal a tough winter ahead, but the dry look to the patterns signal otherwise. I have seen patterns like this blossom into severe winters. Back in the fall of 1993, we had many days similar to this November. There were many sunny, pleasantly cool days, followed by many cold, frosty nights. There wasn’t much in the way of storms that November either. However the following winter was severe, with some 26 snowstorms paralyzing the Boston area from late December through the spring equinox.In the end, I believe the average temperatures trump precipitation patterns. Will this winter have similar results? Tune in next Monday for my official 2012-13 winter forecast!
Now for current weather events across the country. Aside from an early season nor’easter at the beginning of the month, things have been very quiet across most of the country. Yes, arctic air is building up over Canada, so this will need to be watched as we head towards December, but other than that, it has been fairly tranquil. It has been quite stormy across the Pacific Northwest. This in itself is not unusual. However, in a year that was supposed to feature a week El Nino, this is unusual. This type of pattern is consistant with La Nina years, such as last year. My feeling is that there still is a lag effect from the pattern of last year. It shows up sometimes at the beginning of the next season, only to switch as the new season begins to mature.
Normally, when the Pacific Northwest is stormy, New England is not. This is because of the way the wavelengths are set up in the jet stream. When there is a trough out west, there usually is ridging, or high pressure over the east. There are exceptions to this rule sometimes. For instance, this fall, the jet stream has been surpressed south of our region due to the influence of the Greenland Block. This was missing last winter, and could prove to be the link for more stormy weather this winter.
Now for your weekly autumn outdoor activity and travel forecast. I will rate this week an 8 out of 10. Not bad for the third week of November! There won’t be many weather changes through Friday. Look for some sun mixed with clouds for the rest of your Monday. Temperatures will remain below normal, with highs in the upper 40’s. It will be another frosty night, with lows mainly in the 20’s and low 30’s.
Expect winds to freshen a bit from the northeast for both tomorrow and Wednesday. This is in response to the developing ocean storm well to our southeast. This will do two things. One, it will increase some cloudiness, so it may not be as sunny, and two, it will bring slightly milder air into the region. So expect temperatures do be near 50 both Tuesday and Wednesday, and lows will mainly be in the 30’s. It will be mainly dry. However, if the atmosphere moistens enough, there may be a touch of drizzle Wednesday morning?
Look for some early morning clouds for your Thanksgiving Day, then some afternoon sun is possible. It will turn a bit milder during the day, with temperatures starting off in the 30’s, but warming into the lower 50’s in the afternoon for your after noon walk. Look for the fair and mild weather to continue into Friday, with high temperatures in the mid to upper 50’s!
As for next weekend, look for mild temperatures to continue into Saturday, with possibly a few showers moving through. I am not expecting a washout. Watch for dropping temperatures on Sunday, with highs starting out in the 40’s but falling into the 30’s by afternoon. Don’t be surprised if you see a few snow showers during the day, as the cold air rushes in.
Well that’s about it for now. Next week, look for my official 2012-13 winter forecast for New England. I will also have your forecast for the last week of November. In the meantime, please keep those who are less fortunate in mind during this holiday season. Wishing everyone:
~ A SAFE AND HAPPY THANKSGIVING!~ Thanks for reading.
