Major snow event in Eastern Ontario/Southern Quebec...

#1 Postby jj_frap » Fri Dec 10, 2004 10:47 pm

Up to a foot of snow possible by mid morning Sat. in Seaway Valley (where I live), Ottawa Valley, and Montreal Island.

Woke up Friday morning to freezing rain and extremely icy conditions.

Mild afternoon (35 or so) with cloudy skies and occasional drizzle melted much of morning ice.

Temperature dropped to about 30 by late afternoon and we got a couple of hours of freezing rain again, which turned to sleet by 6, and slowly began intensifying and changing to snow. Rapid intensification between 8 and 9 PM.

Currently heavy snow, 20 - 25 mph winds, reduced visibility, and fair-to-poor driving and pedestrian conditions. Temperature hovering in low-30s just below freezing.

NWS is forecasting up to 15" for St. Lawrence county and the Adirondack counties as well. Hope you enjoy the snow!

Got a foot Friday night and another inch or so yesterday.

It's been cloudy for at least three days now even though the Satellites have oddly not always shown clouds.

I live in a pretty weird place though: Cornwall is on the Seaway Valley right between Montreal and the Eastern end of Lake Ontario.

The St. Lawrence river and, to a lesser extent, Lake Ontario tend to draw more moisture to us than to Ottawa or Montreal. (Moisture from the Great Lakes tends to right along the Seaway Valley much of the time.)

When we're hit by snow or by ice events, we're sometimes hit harder than Ottawa or Montreal. (This phenomenon was also evident in the Ice Storm of 1998, but the difference was about half an inch out of four inches.)

Just as often, however, the fact that we're South of both cities and the moderating influence of the river leads to storms bringing us rain as opposed to snow or ice when the temperature is marginal, as it was this time around.

Local paper today said 35 cm (14 inches) from the storm.

That must mean we got 2 inches Saturday after the nasty weather ended.

We had periods of light-to-moderate snow last night and this morning that have resulted in a few inches.

It's currently snowing hard enough right now that about 1/2 - 2/3 of an ince will acculmate for each hour that it falls, although I'm not expecting much more.

On Edit:

I say this with the caveat that every radar map I've seen since Friday has understated the level of precipitation and moisture in the Seaway Valley.

So who knows?

The current forecast is for 1 - 2 inches more by tmorrow afternoon.

Currently on the ground is the thickest and heaviest snow pack I've seen since March of 1993, where storm after storm dumped 1 - 2 feet of snow (per storm...A typcial winter storm here will dump 4 to 8 inches of snow and may also bring some rain or ice.) on the area.
