Will all depend on how the 850s are and how high north the low gets or doesnt 

[PompeyFC]

What is a 'Polar low'?

Submitted by uk.sci.weather on Wed, 17/01/2007 - 9:56pm.

When arctic-origin air in winter flows southward (northward in the southern hemisphere) across (relatively) warmer seas, strong surface heating acts both to enhance the degree of instability, and trigger vigorous moist convective towers. This is sufficient alone to give rise to heavy, wintry showers/cumulonimbus clusters etc., but often marked troughing, or even a closed circulation in the isobaric flow is found; the resultant low-level convergence/positive vorticity enhancement, plus the localised concentration of the latent heat energy released, enhances development within the system, and an intense (but synoptically small) area of rain, hail, sleet or snow & squally winds can result

Fair play. I may book it off and include a caveat that I may cancel! Win-win!

the Siberian air is that cold the disturbance in the flow after coming over the sea is causing the precip to increase and become more organized - in that sense of the word and because even though the air is coming from the east - it originated from the artic being that cold - so can be considered a polar low or a rash of precip which forms a more organized front

10 mm max in SE Wales - the polar bears aren't going to be happy with that?

[thetipster]
