Here is an example:

Rain early...then remaining cloudy with showers in the afternoon. High 16C. Winds ESE at 10 to 15 km/h. Chance of rain 70%.

This is embedded via this short code:

[wunderground location="Toronto, Canada" layout="table-horizontal" hidedata = "search,date"]

This is a standard install, no mods.

Any ideas why this is happening and how to fix it?

Otherwise the plug in (short code) looks cool and works.

FYI this is a duplicate of a post in Wordpress Support Blog as I noticed that this was the preferred issue reporting method.
