Wind chill: Ok, fine, I’m sorry

February 19, 2015 @ 20:30 By: gordon Category: Weather

So, my post from yesterday suggesting that wind chill is a matter of perspective was perhaps not well received by some. In particular, it appears to have not been received at all well by the local weather gods who are blessing Ottawa with the following bit of weather:

3:14 PM EST Thursday 19 February 2015
Extreme Cold Warning in effect for:

  • Ottawa North – Kanata – Orléans
  • Ottawa South – Richmond – Metcalfe

A prolonged period of very cold wind chills is expected.

Bitterly cold arctic air has once again returned to Southern Ontario. Strong northwest winds will combine with the frigid temperatures to produce wind chill values of minus 35 to minus 40 tonight into Friday morning. Wind chills will slowly improve by Friday afternoon as temperatures slowly rise.

warnings about frostbite, et cetera…

Meanwhile, in Florida (the state I may have smirked at in the aforementioned post):

SENSITIVE VEGETATION.

A LAKE WIND ADVISORY INDICATES THAT WINDS WILL CAUSE ROUGH CHOP

Geez.

This atypical weather in Florida is almost certainly going to have a significant impact on the fruit crops such as oranges and strawberries, which are an important part of the economy in Florida.

My mom posted on Facebook yesterday evening that there were warnings on tv telling people how to safely operate their space heaters. I guess when you rarely have to use them, you may not be aware of how to use them safely, something that we in Canada take for granted.

Still, it’s bloody freezing cold out and the only respite in the near future seems to be a weekend of yet more completely unnecessary snow.

Sorry Ottawa. Sorry Florida. I’m sorry.

Wind chill: Sometimes it’s a matter of perspective

February 18, 2015 @ 13:03 By: gordon Category: Weather

My parents are hiding from the winter in southern Florida, a strategy I can’t find any fundamental flaws with given the stellar weather we’ve had of late in Ottawa. Their emails have included pictures of the beach at the place they’ve rented, pictures from the golf courses and so on. They’re not exactly gloating about the sunny warm weather, but…

So, when I checked the weather for where they are this morning, I must admit that I may have smirked a bit.
Florida wind chill advisory
16 °C and a wind chill advisory … It’s even possible I snickered ever so slightly. [ Just kidding, Mom & Dad! I’ll see you down there in about 3 weeks! 🙂 ]

(For reference, at 11am this morning, it was -13 °C, with a wind chill of -19. And today is one of the warmer days lately. The weather tomorrow morning (when their wind chill advisory is for) in Ottawa is forecast to be -14 °C, without the wind chill.)

Gord’s Rule of Thumb About TAFs

I have a rule of thumb about TAFs: the longer they are, the crumbier the weather is going to be.

Swirling gusts at dusk

Cold air brought some snow

Warm rain will melt it anon

Winter comes again

Three fronts in one day is a bit much

If you’re sensitive to changes in air pressure, you’ve probably found today’s weather a bit taxing:
