Hi all,

I desperately need some information on models. I'm flying to UK for my daughters wedding December 10 from Saint John New Brunswick. Long term weather on weather network has indicated a possible NorEaster.

Just wondering if you can be a little more specific of it probable track. I know that's not an easy thing to do, but just a ball park or what the majority of the patterns are indicating.

Many many thanks

Debs

This what the GFS, ECM and GEM ops are going for and at the moment it's good and bad news. You certainly don't want the GFS version. But we are talking seven days so best wait a couple of days to which way they are going to swing.

 

But your best bet is consult the professionals at Environment Canada.

I'm not quite sure knocker, but I think there may be a problem with the colour coding of those maps, the Australian maps on Weatherbell for example are defiently out of whack.

In what way Styx. If they are I can always drop a line to Mr Maue? I think the US ones are okay as there have been some extremes.

the black line is what it currently is and the pink is the normal average?

I think the (blue)black line is the min and the pink line is the max.

It looks very cool for Orlando to me. Probably Knock's point.

 

MIA

[Heisenberg]

It is indeed :-(

 

Oh well fingers crossed for me that it is closer to the pink lol

 

thanks guys

An active weather pattern is on the way with some significant changes expected as 2014 comes to a close.

[Roger J Smith]

If anyone's heading to New York or that general area, expect a very active weather period on Christmas Eve into Christmas Day. It will gradually turn warmer this week peaking around 15 C on the east coast some time late 24th or overnight hours, heavy rain may contain gusty thunderstorms, then it will turn colder with strong southwest to west winds on the 25th. Temps will fall to about 5-7 C. Snow is only expected well inland over higher ground and more extensively in lake effect snow squalls. The temperature drop in Toronto will be even larger, from about 13 C on Christmas Eve to -2 C by late Christmas Day. This same storm could bring some severe storms to Florida on the 24th.
