The cyclical nature of weather has been definitely demonstrated so far this winter. The temperature swings have been astounding and, at times, dramatic in just a matter of hours but recently we have been experiencing a lengthier spell of mild weather. In fact, following a frigid first week of the month, the mean temperature for this January has now flipped to a fraction above average thanks to the thaw!
Based upon statistics, the coldest part of the winter, on average, occurs during the period of January 20-25. Checking the last 5 years, that is exactly what happened in January of 2013, 2011 and 2009. Will that happen this January? Well, with the exception of the 6th, we’ve already experienced arctic air on January 2-9 so the big question is whether there will be a sequel this month.
At the end of November, I posted my winter outlook which called for a below average mean temperature for the season with near to above average snowfall but less than the 63.4″ of last winter. So far, officially, Boston has received 27″ with some places on the North Shore over 40″! Where is it?
What goes up must come down and that is precisely what will be happening with the temperatures over the next 48 hours. We’ve been on quite a thrilling roller coaster ride with temperatures falling several degrees below zero Friday night then rising 25 up to 40 degrees yesterday. The ride leveled off a bit today but will rise more sharply late tonight and tomorrow past 50 degrees many areas before plunging again tomorrow night. Fasten your seat belts!
It’s free, it’s been advertised for days and many of you hopped on the temperature roller coaster yesterday. The ride has begun and it’s going to get wild. Thanks to the mass of arctic air, a fresh snow cover and diminishing wind, radiational cooling initiated the chill thrill last night as temperatures plunged into subzero territory over 96% of New England. Boston’s +2 was 6 degrees short of the record -4 set in 1981.
Are you ready for a roller coaster ride? After tonight’s arctic chill followed by the weekend warmup to 40 on Sunday, temperatures could spike a dozen degrees higher Monday morning if a developing storm in the Ohio Valley surges across western NY into Ontario and Quebec.
Some harsh winter weather is impending as we get ready to ring in 2014. Bundles of energy are gyrating along in the jet stream so the atmosphere is primed to produce snow followed by a blast of frigid weather.
Following an autumn of peaceful weather overall, us forecasters will be busy bees over the next two weeks following lots of weather changes across North America. The jet stream is becoming supercharged with parcels of energy in a state of flux so troughs of low pressure will be undulating and gyrating across the continent in varying amplitudes.
The evolving weather pattern is going to keep us on the edge of our seats for at least the next week. The cast of characters is growing larger and the plot may thicken at any time. The presence of arctic air building in Canada way back in late October and November caught my eye and we subsequently have seen several attacks of harsh winter temperatures into the nation.
