Those figures appear a little extreme. I am only 10 miles to the East of
Carlisle and only recorded -0.8c !!

Could the Carlisle figure have been reported with a decimal point
misplaced?

ATB,


The min of -9c at Carlisle looks a bit suspicious to me.

The hourly temperatures reported were

2300 1.7c
0000 1.8c
0100 0.2c
0200 -0.5c
0300 -1.9c
0400 -0.7c
0500 -5.4c
0600 temperature not reported
0700 no report
0800 1.1c

In the 0600 SYNOP the only item reported was the minimum temperature of
-8.8c. Everything else in the SYNOP was missing.

The temperature of -5.4c in the 0500 SYNOP looks wrong. The MSL pressure
reported at 0500 was 922.4 mb which is obviously wrong. The pressure
tendency at 0500 was reported as falling 56.6 mb in 3 hours, also
obviously wrong.

It looks to me as if the instrumentation threw a bit of a wobbly.

.... remarkable, if correct: the EGNC first METAR has a temperature of
0C - a dramatic rise from an overnight min of -9degC! Doesn't appear to
tie in with WeatherOnline's own plots of minima in that part of the
world either.

If you want to see a crass automated output - have a look at the Met
Office index page and the symbol chart showing sunshine and showers for
the southeast: I am looking out at a grey, misty downpour - sunshine not
on offer.

Hi, Norman,

Could well be - a lot of AWS are, but the screen min at Copley was
below -2C and we are on a hillside not noted for low minima. I estimate
Copley Mill would have been below -6C as were Topcliffe, Redesdale and
Teesside airport.

I stick by my suggestion that the computer forecast was not as bad as it
was thought to be.

ATB,

I've also had a look at the Carlisle SYNOPs for the previous night, when
Carlisle reported a min of -5.0c. That also looks wrong. The hourly
temperatures and MSL pressures reported we


2200 3.5c 1007.3 mb
2300 3.5c 1003.1 mb
0000 -1.0c missing
0100 -0.3c 964.8 mb
0200 1.4c 996.4 mb
0300 SYNOP reported with all items missing
0400 0.7c 970.8 mb
0500 2.3c missing
0600 SYNOP reported with all items missing
except minimum of -5.0c
0700 SYNOP reported with all items missing
0800 4.1c missing

It certainly looks as if the Carlisle AWS is pushing out some spurious
values from time to time.

Very suspicious as you write, Norman. Assuming conditions were fairly
constant through the night (cloud cover, wind, etc.) it is most improbable
there was a drop of 4.7 deg C between 0400 and 0500 - a time in the night
when the rate of cooling has usually reached its minimum.
