Ottawa: -28C + 1 cup of boiling water + my balcony

January 23, 2013 @ 10:10 By: gordon Category: Current affairs, Photography, Weather

It’s cold in Ottawa today:

So, I decided to throw a cup of boiling water off my balcony:

The view from my apartment

IMG_0616Rob posted a couple of time lapse videos on his Facebook timeline of the snow where he lives in the UK today, so I thought I’d see what I could make with my GoPro camera. The setup was pretty straight forward: I stuck the camera to my bedroom window and pointed it at the street below.

The GoPro Hero 3 Black offers a huge number of options for recording video, but it also can act as a still camera with conventional single-frame, burst mode (up to 30 frames in a 1 second burst) and a time lapse mode. It’s the latter that I chose, choosing a 30 second interval in 7 megapixel mode.

Once I had everything set up, I hit the trigger and left it running for about an hour and a half. After it was finished, I used Microsoft Live Movie Maker to combine all of the images into a single video, which you can see after the break.


Touché, Air Canada

I’m really not a morning person, and I’m ok with that. I like to travel, but I’m not a fan of really early flights. And based on the comments on some of the flights I was looking at yesterday, Air Canada knows this, too… air canada - early morning


Can you spot the warm front?

It looks like we’re probably going to see some freezing rain beginning over the shortly before the lunch hour and continuing to mid-afternoon:

Hopefully, it won’t make the afternoon commute too treacherous.

Here it comes

The incoming warm front I wrote about earlier can be seen on the edge of the composite radar image for Ontario:

Incoming warm front. Sigh.

So, I see from the Weather Office’s website that Ottawa is under a freezing rain warning for tomorrow afternoon. Judging by the TAF, it’s not going to arrive until noon, and even then it’s only showing as a 40% probability from noon until 1PM (the end of the forecast period).

warm frontYou can see the warm front passing through based on the wind directions in the various periods in the forecast. At the beginning, it’s out of the northwest at 5 knots, becomes variable at 3 knots at 0000Z (7PM) and then is out of the east at 5 knots early tomorrow morning. So, in about 12 hours it flips around almost 180 degrees. Fun.

We’ll get freezing rain if the air being overrun by the incoming warm air is sufficiently cold enough to cause the rain drops condensing at the boundary between the warm and cold air to be supercooled so they freeze instantly on contact.

Ottawa forecast for January 11-13, as of January 10The next TAF should clarify how long the freezing rain is going to go on for tomorrow, but any way you slice it, it looks like my plans for snowshoeing on Saturday are probably going to be a bust, as you can surmise from the graphic.

So much for snowshoeing this weekend…

Ottawa forecast for January 11-13, as of January 9I have been looking forward to going snowshoeing this weekend with a bunch of friends for a while now, but having just looked at the long-range forecast for this weekend, I’m not at all confident that’s going to be possible.

As you can see from the graphic I clipped from the Weather Office’s website, there’s probably going to be freezing rain on Friday, which will put a crust on the snow. Then it’s supposed to go up to 11°C on Saturday, which is going to make the snow really sticky, and that sucks when you’re snowshoeing.


And this is going to set the canal back quite a bit, too.

Nuts again.
