Snowy Sunday

Travel southwest along the 401 and 20 was difficult this afternoon. PJ photo

That little bit of "light snow" this afternoon put down a quick 5-10cm of snow in the St. Lawrence Valley between 1 and 5pm this afternoon. I was attempting to drive from Ile Perrot to Kemptville, and gave up at Cornwall. The snow was heavy and wet with significant accumulations on the 401. The visibility in heavy snow was under 1km most of the afternoon with several cars in the ditch and travel slowed to under 70km/h. It has since tapered off to flurries. It is not to often I get caught in a missed forecast but today was one of those days. The warm air never made it down to the surface in the St. Lawrence Valley so instead of the precip changing to rain, it remained snow. The enhancement of the snow was from a frontal trough sliding southeast into New York state.
