WeatherAction forecasted weeks ahead that there will be many dangerous weather events around the world in the period 25-31 Dec and specified a triple whammy of extreme events for Britain/NW Europe, NE/E USA and South/East Queensland Australia.
ALSO see here for comment "Will it or won't it on Xmas day in UK?"
The period 25-31 Dec 2010 is a Weather Action Red warning (World) period with top activity expected in sub-periods 25-27th Dec & 29/30th Dec.
"There will be many dangerous weather events around the world in this period", said Piers Corbyn astrophysicist of WeatherAction long range weather & climate forecasters. "Snow/blizzards/rain (where appropriate) and winds will be much more severe than standard meteorology will predict from 2 days ahead in these periods"
"For Britain/Europe, NE/East USA & East Queensland Australia we have specific long range extreme weather event warnings which we first issued end Nov / early December. The extremes to come are a consequence of Jet stream blockings and changes in both hemispheres caused by predictable solar-lunar effects".
For Britain and Europe we stated in forecast words & maps:
Two waves of blizzards and drifting snow especially 25th-27th & 29/30th largely for East/South Britain and for a large part of NorthWest Europe (along with thundersnow) around South Scandinavia, Benelux, N Germany, North Poland and perhaps parts of the Baltic States. AND that thundersnow is likley in (North) Italy in this period also.
Piers commented on 23 Dec re Xmas "Our expectation of snow in the UK on Xmas Day is at the starting edge of this Weather period so there are uncertainties. We notice short range forecasts have been changing a lot for Xmas Day which is probably a reflection of increasing solar factors which will upset standard forecasts in this period. We still expect snow in parts of the UK on Xmas day but note that the general centre of this activity appears interestingly to be shifted somewhat Eastward in Europe so snow amounts on Xmas day itself in the UK will not be large.
