  1. I went to Miami this christmas and have a friend who lives there. Hurricane Rita was so bad the everglades park was still closed in late Dec two months after Rita. Whilst i was there we got to talking about the hurricane season and the info from the Florida Hurricane Centre is that this comming season is expected to be as active if not worse than last season.

    Believe me the Floridians are getting prepared.

  2. N-W radar showed a small snow shower (blue) creeping through towards the Oxford area. I tracked it until 10pm it was positioned directly over here. Rain. Crap again.

    Unless i'm mistaken then blue means rain. Pink means snow on the NW radar. Sorry to correct you i just don't want you to be dissapointed when you see blue blobs and think they are snow. ;):(

  3. I am amazed at how unaccurate the forum forecasts were a week ago, espescially as on wednesday it began to look much more likely that we would get snow. Well done all the forecasters who got this wrong once again.

    S**T start to winter. :)

    JK LOL

    Are you sure you arn't Damien he post silly comments like that. I feel that all the peeps on here do a great job and i for one would trust their advice on the weather over general forcast from the beeb and others. :)

    They are all volunteers on here and give their advice and time for free.

  4. Can anybody tell me if this poss snow event could poss cause problems for travel from Devon to Kent on Friday during the day? My 17 year old daughter left today for a A level feild trip in Devon and is due to come home Fri could this cause a delay or will she come into the poss snow when she hits |Kent?

    Thanks for the replys in advance.

  5. I'll stick my neck out here and have a go. Warning: the information contained within may be total bullplop.

    A bit of background. The Polar Front Jet or PFJ circulates the globe from West to East. During the summer it moves North and during the winter it sinks South. If the jet circulates in a very flat pattern with little north and southwards variation it is said to be zonal. When the jet is zonal, the weather of countries near the jet will be dominated by westerly winds. In our case, this means generally mild and wet weather coming in off the Atlantic. Places north of the PFJ will be in cold air and placed South of the PFJ will be mild. If the jet is zonal, it will generally be to the North of us, leaving us with mild, wet weather.

    The jet is never perfectly flat though and it will have kinks in it which are called long waves (long waves are also called Rossby Waves). If these waves amplify sufficiently you enter a meridional flow where cold air flows south from the Arctic and warm air flows north. This happens side by side with Southerly winds pushing the warm air North and Northerly winds flooding cold air South.

    I think what Steve was referring to with a 4 wave pattern is that there are four Rossby waves in the PFJ, which produces a stable jet flow - potentially for quite a while, and this implies that our current synoptics stay locked in because the jet doesn't flatten and break through the Mid-Atlantic block.

    That's my understanding anyway, I'm sure someone more knowlegable can correct me if it's all wrong!

    Wow Evo that was a realy good explanation i understood it in leymans terms.

    Thanks :(:)
