After a one-day warmup yesterday, which tragically was still a colder than normal day, colder air has returned today with highs around 10 degrees below normal. Normal high today is about +3°C. Unfortunately, another -20°C night is expected tonight, some 15 degrees below normal.
A clipper system will usher in some warmer air for Saturday. Unfortunately, winds look to be an issue however, coming from the south at close to 40 km/h. Some snow will be possible, but there remains some uncertainty on amounts. At this time, only small accumulations, if any, are expected. There may even be some mixed precipitation in the evening as even warmer air moves in. Temperatures may exceed the freezing mark in the evening.
As has been the story of the winter, warmups are always very brief. And so, colder air starts moving in by Sunday, and therefore the beginning of next week looks colder than normal. By then, normal highs are around 5°C.
For those hoping for a warmer than normal April, the odds are against us. This December to March period will end up around 10th to 12th coldest on record since 1872 (finalized stat to come in the March summary). Unfortunately, of the 20 coldest December to March periods, NONE were followed by an April that was warmer than the 1872-2013 average April mean of 3.5°C. As such, a warm April is highly improbable. However, for those wishing for warmer weather, here's hoping we can buckle that trend this year.
