It appears that the weather is a going to be tad unsettled this afternoon:

In short, that says it’s going to be very windy out of the southwest to west with thunderstorms of varying intensity (hint: +TSRA is a heavy thunderstorm) with light rain thrown in for a bit of variety.

Ick.

I thought I’d take a quick look at the weather to see if a bike ride after work would be possible.

I guess not, particularly as we’re under a severe thunderstorm warning at the moment. Oh well.

And the radar is kind of exciting, too…

It looks like we’re in for some (potentially) exciting weather today:

Rain with periods of rain (just to be different!), gusty swirling winds, possible thunderstorms, and drizzle. Whee.

The forecast for tomorrow has no redeeming features:

Basically, that says light rain showers overnight, gusty winds, rain and mist becoming freezing rain and pellets (yum!) around 9am, which will become snow pellets in the early afternoon and finally snow and blowing snow around 5pm tomorrow afternoon.

I want no part of this.

Saw this in my RSS reader this morning and it made me smile…

I looked out the window at work a few minutes ago and saw the leading edge of a wall of snow moving in:

About 30 seconds later the view was this:

And about 20 minutes later it’s back to normal:

Between the time of the first and last photos, the RCMP closed Sir John A. MacDonald Parkway along the shore of the Ottawa River because of the lack of visibility.

On the Franktown radar, it looked like this:

Just before noon today I noticed that the sky to the north of the Ottawa River was nice and clear, while the sky to the south was overcast. Well, that’s because the boundary between the high pressure to the north and the low pressure to the south was more or less right there.

The temperature at Ottawa Airport a few minutes later (i.e. noon) was -5C, while in Pembroke about 2 hours to the northwest it was -12C and -16C in North Bay, which is a couple of hours past Pembroke.

If you check out the following two graphs, you can see the incoming cold air coming in from the northwest:
