Exciting weather this afternoon

July 23, 2012 @ 13:16 By: gordon Category: Weather

It’s shaping up to be an interesting afternoon weather-wise. I took a look at the Franktown radar a few minutes ago and saw a large purple blog making its way towards Ottawa. The snapshot to the right is the most recent radar image (as of about 12:55) and the purple blob has spread out a bit and become a red and yellow blog that covers a slightly larger area. The track of the incoming weather suggests that the strongest part of the storm is going to pass just to the south of Ottawa, but that could change, of course, or the rain north of the blob could pick up some energy and develop into more exciting weather.

Looking at the weather trends for the last 24 hours, you can see the pressure had dropped since noon yesterday:

The aviation forecast suggests that we’ll see thunderstorms, possible including hail, from 3pm:
