As it's now winter and delays due to weather are on the increase, this could be a good place for any weather-related updates pertaining to aviation/airports.

Link to SIGMET map here. Select Layers to overlay satellite, winds, etc.

●Strong jet stream winds (thick black lines with pennants (each worth 50 knots) and barbs (each worth 10 knots), with the Flight Level of the core marked (e.g. FL340 = 34,000 ft. Extra levels show the boundary of 80-knot winds)
●Clear-air Turbulence (CAT, numbered dashed areas, see legend for upper and lower levels),
●Areas of icing and turbulence (squiggly lines, with upper and lower levels. XXX means Below FL100),

Flying to new York Thursday, how bad does it need to get before I need to start worrying?

When they cancel the flight, which is also when you can stop worrying (about the weather at least)

Depends on how the airport handle it, if they can keep the manoeuvring areas clear you dont need to worry but anything dumping of snow will probably overwhelm their capacity to clear snow do some disruption is likely.

Not actually working for me, weather info won't load. Aeroweather also being very awkward this morning, not loading METAR's for some airports, refusing to show TAF's for airports outside irelsnd, refusing to show previous METAR's.

I'm thinking they all use the same data source and hence are all affected when it has issues.

I've found an online site called aviador which works very well, and also has some interesting charts such as the wind profile for an airport.

be interesting to see dublin copes with the possible bucketloads of snow next weekend.

In the last update. Also using the paid version.

Hmm, I can't find it there either now, and when I open it it's not retrieving data due to a server problem. Try again later maybe.

Unless knock airport has packed itself up and moved down the road to Shannon but I sincerely doubt it.

As I said, I was being pedantic. The TAF was issued by the aviation team in Shannon, hence off the press from there.

That's some windshear at just 100 ft agl but it is noted that this can occur due to the large buildings west of the threshold of R24.

Some interesting notams for Dublin. I wonder what weather conditions they're talking about over such a long period? Just winter brooding?

its a period of winter when starling and other "short-haul" migratory birds reach their peak number in British Isles.. certain species, like starlings are full time residents in Ireland however through the winter they are joined by their Nordic siblings .. at least that's my understanding of it

Thanks, I was just interested in why he used Shannon, but with the winds against him, it probably made sense.

in my relatively short experience haven't seen a value reported that high, sounds even unbelievable at first, but looking at reported winds on the ground and forecast for the winds aloft, perfectly possible I guess.. strange conditions today.. if windy.com is anything to go by, looks like a trough is sitting right on west coast which would explain the occurrence
