February's weather patterns and a look ahead: When will spring arrive?
February has featured well below seasonal temperatures across much of the Canada. During the first half of the month, a coast-to-coast cold pattern resulted in numerous record lows from British Columbia to Newfoundland.
This was followed by a somewhat milder but more active pattern, but central and especially eastern Canada have also felt the full force of February’s fury with a series of winter storms.
Despite a period of mild temperatures, most Canadian cities are still running below seasonal for the month of February. The map below displays temperature anomalies across North America through the February 20th. The regions colored in blue, green and voilet have been colder than their average temperatures for the month, while the orange shaded areas such as in the Arctic have been warmer than seasonal.
For those who are hoping for an early spring, unfortunately the news is not good. We are transitioning back into the pattern that we have already seen several times this winter with air masses that originate in Siberia crossing over the North Pole and tracking into central Canada.
The map below shows forecast temperatures relative to which locations would typically see during the final week of February.
Areas shaded in dark blue and purple (from southern Saskatchewan to western Ontario) will see temperatures 10 to 18°C colder than their average temperatures for the last week of February with numerous record lows possible. To the west and east of this region, temperatures will also be below to well seasonal.
