Not sure if weather questions belong here, but it is a technical question!
Other than 'the pressure contours are close together', is there a means of estimating forecast wind speed from the pressure gradient on a synoptic chart (e.g. I'm interested in understand how close together the pressure contours need to be to result in XX knot wind, for example)?
While the weather is a bit wet, I'm trying to throw myself into lots of learning and reading to further my met knowledge and - as part of this - I start my day looking at the synoptic charts and trying to put together my own forecast, which I'll then cross-reference against the actual produced forecasts.
Where I'm struggling is that I look at the chart for tomorrow - for example - and over the South-East the lines don't appear that close together (relatively!)...

...but then when I look at the forecast it's pretty breezy: 30 knot gusts!

I can't see from this chart where the forecast of strong winds is coming from - is it just the case that my definition of 'close together' isn't the same as others?
