Global model output suggests this front on a convergent trough with a
pre-frontal low-level jet (~30 m/s) will form into a sharp ana-cold
front. Expected is a core/gap morphology with Line Echo Wave Pattern
characteristics. UKMO invent output (presumably processed 1.5 km var)
is predicting such-

There is a risk of localised damaging winds and brief tornadoes.
I would be grateful if reports of damage and unusual AWS readings
could be amended here. It is important that AWS users switch to high
frequency logging. 5 min logging is insufficient to record the frontal
passage.
Time frame is 18Z 24th to 06Z 25th all of England and Wales as the
front progresses eastwards,
thanks,
