Nova Scotia's Carbon-Copy Weather

Imagine waking up to the same day over and repeatedly with the same music, but most importantly, the same weather, and not the good kind! Just like in the movie Groundhog Day. 

Much of Southern Nova Scotia has been dealing with the same type of weather since the beginning of 2018. Only 7 days into 2018 and there has been so much weather happening causing problems. 

Since Christmas Day, it has not stopped snowing, each day has recorded some amount of snowfall. And to this day today, January 7, 2018 it is still snowing! December has picked up 51.4 cm of snow in Yarmouth, above average from the average monthly snowfall of 43.7 cm, in January the average snowfall is 68.5 cm, so far since January 1st, Yarmouth has picked up between 20-40 cm. 

2 days later, an arctic blast bringing air temperatures of -5 and below, with overnight and morning lows in the -10’s. For a coastal town near the water, these temperatures are very rare and even more rare that they are in a very prolonged period! Between December 27th and January 3rd, temperatures have been below -5 degrees, with mornings in the -10 to -15 range, the average temperature in December is +4 in Yarmouth, Thanks to many milder days in the start and middle of December, the month came close to seasonal with an average of 3.1 degrees. Just 0.7 degrees below normal. January average temperature is +1… so far since January 1st the average temperature is -3, only 2 days were on the plus side and above average, January 4th and 5th, during the big storm, temperatures those days where 3 to 10 degrees. 

After the brutal cold, came the storm on January 4th, first bringing rain and tropical to Hurricane force winds, damaging storm surge and extreme coastal flooding, this cause school closures, the storm raged into the 5th with over 135,000 people with out power in Nova Scotia, and with near blizzard like conditions, schools were closed again for the 2nd time. 

Yesterday and today, was not better. Wind Gusts of 50-70 km/h created snow and blowing snow, so bad that it was like an all-out blizzard and in fact, if it was only 2 km/h higher wind speed and a visibility of .2 km lower at 10 am yesterday, it would have been an official blizzard! Which is 4 hours of wind speeds greater than 40 km/h with falling snow or blowing snow combined to give visibility of 0.4 km. 

Much of the last 3 days resulted in visibility less than that. 

And in combination with the near blizzard like conditions is the return of more arctic air, again temperatures of -5 to -15 with wind chills in the -20’s for the last 3 days. 

The arctic cold is creating many damage to homes and churches with pipes freezing, and those outside not properly dressed are in the ER, which is unusually busy. 

Yesterday and today have cancelled numerous businesses and events. And that continues today, with many church masses cancelled. 

The storm overall, created much damage, from house and boat fires to breaking wharf's, throwing boats onshore, and tossing huge objects such as a trampoline in the middle of the road. House sidings, windows and roofs were damaged. Many roads were washed up due to high waves in combined with storm surge. 

Question is from everybody’s mind.. is when is the weather going to go back to “normal”?

Today, despite the cold and gusty winds which will create continued blowing snow which will cause near 0 visibility, it wont be as bad as today, and there are to be some breaks of blue skies. But wind chills will again be in the -20’s. 

Another low associated with a warm front will bring snow tonight into tomorrow with amounts of 5-10 cm, good news is this is a warm front, combined with a flow from the South-West thanks to an very large area of High pressure to the south, so temperatures will rise tonight and be close to, if not above 0 tomorrow. The same front will bring the snow changed over to rain by Monday night into early Tuesday morning, with above 0 temperatures, which is where they should be for this time of year. 

It briefly gets cold again for Wednesday, but some sunshine.. Thursday warms up with temps near 8 degrees, that gets better into Friday, as temperatures on Friday will reach near 15! Similar temperatures for Saturday, however a more tricky call.. a cold front will try and swoop down by Saturday afternoon, but becomes stationary over Digby and Yarmouth, if this holds true then Saturday will see temps of near 10 in Yarmouth then falling in the afternoon, while Shelburne will see near 15 degrees on Saturday, if the front stalls and is delayed, all of southern Nova Scotia will experience the 15 degree warmth. By Monday another spell of sub 0 temperatures return. 

Temperatures of 10-15 degrees in winter in this part of the province is common, in December there was more than 10 days of 10 degrees and above. And during the storm, temperatures soared to 10 degrees, with some locations reported being near 13.
