Châteauguay Valley Weather February 13-19, 2022

Peter Finlayson, Ormstown weatherman
The yo-yo weather was with us in extremis last week: from Tuesday to Wednesday the temperature rose 30 degrees C, from about -20 to 10 C; then from Wednesday to Thursday, it dropped the same 30 C back down, before rising and sinking and rising and sinking about 20 C each day from Friday to Sunday.

And we’re not done yet. The temperature on Wednesday and Thursday for the coming week is forecast to drop from 8 to -16 C, another 24 C swing within a 12-hour period.

Despite all the ups and downs in daily temperature range, the average has finally reached normal! The average temperature for February is now -7.7 C, down a degree from the previous week at -6.5 C, and pretty close to the normal of -8.0 C. Given the extreme swings in temperatures this month, what the average will be at the end of the month is anyone’s guess.

February has now moved from being a dry month to a wet one. There were 27 mm of rain and 26 cm of snow in the last week, bringing the total month-to-date precipitation to 87 mm, which is what one would expect for the entire month. With rain and snow forecast for the last week of February, the extra moisture will make up for the deficit in January.

The snow cover increased briefly to 25 cm at the end of last week before the gusty winds on Saturday brought it back down to 22 cm. This is the first year in a long time that there has been continuous snow cover with snow staying on the ground from the first snowfall of winter (in December) until the end of February.
