Frost tonight in the SE

Before the pressure goes up on this Thread, I know that my Weather Station is correct as I have one or two barometers and they are all registering the same.

 

29.4" here - no buttons, batteries or screws on mine - afraid it's just a glass tube filled with mercury

 

The best sort probably!! I've got an old French "Banjo" Barometer, an old Ships Barometer [both aneroid] a Dial Barometer [aneroid] and a Stick Barometer [Mercury] and they're all agreeing with my Digital Wireless controlled Weather Station.

 

Well, I sit, so to speak, above the Cheshire plains and in fact can go half a mile and look down on them. But my Digital Barometer and Slaves are calibrated to my House's above sea level and, as I said before, all my other Barometers are reading the same as it

 

To be honest, Pete, I don't have much faith in the Met Office weather chart stated isobars during "disturbed" weather patterns. I'm less than 20 miles from the Coast, overlooking the Cheshire Plains, and this area, along with a few others, has a reputation for the "mini-mangling" of air pressure in that we do sometimes, quite regularly. have different pressures to those not far away to the East etc.
I believe that during the War on the airfields around here, mostly Transport aircraft] the Pilots would use the local air pressure forecast from the airfield Met and then change over to the Main Met when landing elsewhere. If I remember correctly the only time I have noticed that my Barometers will almost agree with the Met Office is during settled weather in the Atlantic and Ireland. I probably put more faith in my Mercury Stick Barometer than the Met Office forecasts and the rest of my Baro's have never really disagreed greatly with each other.
