Châteauguay Valley Weather April 18–24, 2021

Peter Finlayson, Ormstown Weatherman

Despite the midweek snowfall, the weather for the third week of April was pretty much “steady as she goes.”

The average temperature so far this month is now +7.9 °C, down slightly from the previous week at +8.2 °C, but still well above the normal of +6.5 °C. Blooming flowers, everything from snow drops to daffodils to tulips, is an indication of just how warm it has been.

Despite the warmer air temperatures, both during the day and at night, the soil temperature has stayed cool, even cooler than the week before as it went down to +5 °C at night, no doubt due to the snow on the ground for several days.

Corn needs a steady soil temperature of +10 °C to germinate, so the few farmers who managed to get some corn planted before last week’s wetter weather will have to wait some more to see if their gamble paid off.

The 9 cm of snow that fell added some badly needed moisture to the soil. It melted down to 11 mm of water, so combined with the 2 mm of rain that fell, total precipitation for the month-to-date is 43 mm. That’s still only two thirds of normal so the forecast rain and shower activity in the next two weeks will still be welcome.
