Met Office: current synoptic chart?

[nigelmercier]

... So I'm back to the idea of making a compact device which will show:
[1] Current absolute pressure with barograph display
[2] Current pressure with trend display and alarm ...

Further to the above, I've now built a rudimentary device which shows just current temperature and pressure. It took me a while to debug the code, so I'd like to check that the pressure reading is accurate (currently 1017.7hPa in Cranbrook, Kent).

Is there a Met Office or other site that gives a current synoptic chart? Note that I've looked on unofficial sites such as http://aprs.fi but too much variation.

I guess I would need to adjust for sea level, so I'll check my elevation ... [Edit] 114m

And http://www.weathercharts.org gives a long list of weather info.

Why not have a look at the current observations for Headcorn Aerodrome on XCWeather.

a quick call to your nearest airfield (? Headcorn) or any site of the Davis weather station networks

Some of the Davis barometers can resolve to 0.25Mbar.


Here's the map of locations.

Thanks all for handy links. Headcorn currently says 1013, I'm reading 1018.0 at 106m ASL (my study seems to be sinking), so something is a bit adrift. Perhaps I should wait until the isobars are a bit more spaced out.

Indeed you should. Those of us old enough know that spaced out isobars only occur during highs :encouragement:

In the days of the BBC serving the interests of grown-ups, we used to get this information four times a day on the weather forecast. If you are in the Jersey area, Jersey Radio give readings over a wide area in their regular reports.

This has always worked for me.

Alternatively, get hold of an old aircraft altimeter, set it to zero and read off the pressure.
