Default Westward Low

Typically, I can't lay my hands on my copy of Manley ("Climate and the
British Scene") just when I need it, but I do recall his description of a
westward-moving February low, (1920s?) which put a fair bit of snow onto
the eastern Pennines.

I remember, as a teenager, looking longingly at the set-up (he included a
pressure chart in the description) and wondering if and when it might
occur again. I can't recall that happening but I think it must have done.

I'll be interested to see how this one compares to previous incidents.
And if anyone can flesh out that reference to Manley, I'd appreciate it.


Looks like it could be Figure 60, on page 251 of my edition. The caption
reads: "0700 hrs, 25 February, 1933. Very heavy orographic snowfall in
NE and N England and in NE Ireland associated with a low which moved
westwards; snow 6 inches deep at Durham but 30 inches deep in Teesdale
at 800 ft."

The chart shows the low centre over SW Ireland, with south-easterlies
over most of England. Apart from the extreme SW, temperatures for the
plotted stations are all between 32 and 37F (0-3C). Guessing at the
locations of the plotted stations, Cambridge, Leeds, Bristol, Aberdeen,
Holyhead, Belfast and Malin had snow; London, Portland and Liverpool had
rain. At that time English east coast stations were dry, as were Glasgow
and Plymouth.
