Quiet…for now 12/6/10
Many years by this time, we would have already had our first snowfall. In last weeks blog I talked to you about that historic snowstorm which struck Boston back on this date in 2003. Looking back on the records, it does appear that our first snowfall does generally occur about this time of the year. Last year, for instance, we had 4″ of wet snow in Boston on this date. It does seem to go in cycles. Boston can go years without a significant snow until after Christmas. Speaking of Christmas, this is about the time of year when everybody starts wondering whether we will have a white Christmas or not. Historically, if you live in Boston, your chances are not that good. The chances of Boston having a white Christmas (defined as having 1″ of snow on the ground on Christmas morning) is approximately 25%, or about 1 and 4. This statistic varies greatly over the years. For instance, Boston has had a white Christmas for that past three consecutive years! Your chances for snow on the ground on Christmas morning increases rapidly the further away you live from the ocean. At this point, December is looking to be on the colder side, with several chances for storms. I will keep everyone updated on your chances for a white Christmas this year.
Just a quick note on this years temperature departure for November. I knew it was going to be close, but after reviewing the final numbers with the National Weather Service, it does appear as if November finished 1 tenth of a degree below normal for the month. You may say, why the heck is this so important? Well, for one thing, this breaks the consecutive streak of above normal temperatures for each month, which started back last January. This may also be the start of a trend towards a colder winter on the way. In addition, November temperatures are a key factor in determining how much snowfall Boston receives during the winter. It has been proven statistically that when temperatures finish at or below normal for November, Boston’s snowfall turns out to be greater than average (42″ is average at Logan Airport). I did not go for this in my winter forecast, so it will be very interesting to see how this all turns out as we move through this winter!
Now it’s time for your outdoor recreational winter forecast. I am rating this week a 6 out of 10. Remember, the higher the number, the more wintry weather we are going to have. Look for blustery and cold conditions for the rest of your Monday, with mostly cloudy skies, temperatures will be in the mid 30′s. By the way, anyone who lives up in northern Maine will be getting hit hard today with a heavy snowstorm! Expect a biting wind tonight at Gillette Stadium, as the Patriots freeze out the Jets. Temperatures will be in the 20′s, under dry conditions. Tuesday looks similar to today, with maybe a little less wind, and a little more sun. Watch for a passing snow shower first thing Wednesday morning, then clearing skies and turning windy again. Temperatures will be cold, with highs only in the mid 30′s. Look for a some sun through some high clouds on Thursday, with temperatures only in the upper 20′s, brrrrrr! By Friday, we may actually see our first snow of the season! It doesn’t look heavy at this point, but do expect to see possibly some light snow with an inch or two of accumulation. Look for an improving ski and snow mobile forecast this week. All areas will be making snow, and some areas will receive natural snow, especially today, and then again later in the week! By next weekend, things may start to get very interesting. Long range computer models are indicating that a major storm may be developing somewhere over the eastern part of the U.S. The exact path is crucial, whether we get a blizzard, or a windswept rainstorm. I will keep you updated during the week for this possibility. This would begin on Sunday and continue into Monday.
Well that’s about it for now. Next week, I will look back in weather history and talk about another historic December storm which struck southern New England. Also, look for an update from me on the potential winter storm for next weekend. Until then, be prepared for winter time conditions this week, as winter starts to make some noise!
