XCWeather now has the gusts near me (London/Surrey), starting from midday, and getting really strong around midnight. Pretty sure yesterday it was set to start in the late afternoon / evening.

 

Yep, if GFS has this nailed, it's going to get pretty rough down here tonight:

Skywarn:

 

SKYWARN UK SEVERE WEATHER WARNING #048
 
ISSUED: 1800UTC SUNDAY 22ND DECEMBER 2013
 
SKYWARN UK HAS ISSUED A WARNING FOR SEVERE WEATHER AS FOLLOWS:
 
STRONG, POTENTIALLY DAMAGING WINDS - ALL AREAS OF UK
 
HEAVY RAIN LEADING TO A RISK OF LOCALISED FLOODING - WESTERN AND SOUTHWESTERN SCOTLAND, NORTHWEST ENGLAND, WALES, NORTHERN IRELAND, SOUTHWEST AND SOUTHERN ENGLAND
 
IN EFFECT UNTIL 0900UTC WEDNESDAY 25TH DECEMBER 2013
 
RAPID CYCLOGENESIS OF A MID-ATLANTIC LOW GENERATING A VERY ACTIVE COLD FRONT AND SEVERE GALES
 
DISCUSSION:
 
THERE IS EXCELLENT MODEL AND PARTNER AGENCY CONFIDENCE IN THE LIKELIHOOD OF SEVERE WEATHER RISKS THROUGH MONDAY AND TUESDAY. AS A >160KT JET DEVELOPS OVER THE ATLANTIC, A LOW PRESSURE IS ENGAGED AND DEEPENS TO POTENTIALLY SUB-930MB NEAR THE NORTHWEST ON TUESDAY. IN THE PROCESS, A VERY ACTIVE FRONTAL ZONE TRANSITS THE UK, WITH MEAN WIND SPEEDS OF UP TO 55MPH INTO THE SOUTHWEST AND SOUTHERN REGIONS. GUSTS OF ABOVE 80MPH MIGHT BE POSSIBLE INLAND, WITH PERHAPS HIGHER ON EXPOSED COASTS AND HIGH GROUND. OVERNIGHT AND INTO TUESDAY, WINDS OF UP TO 60MPH WILL MOVE ACROSS NORTHERN IRELAND AND INTO WESTERN SCOTLAND AND NORTHERN ENGLAND. DAMAGING GUSTS OF ABOVE 80MPH ARE POSSIBLE THROUGH TO THE END OF THE PERIOD FOR NORTHERN COASTS AND ISLANDS, ESPECIALLY OVER AND IN LEE OF HIGH GROUND. A FURTHER EPISODE OF STRONG WINDS IS EXPECTED FOR SOUTHWEST AND SOUTHERN ENGLAND OVERNIGHT INTO WEDNESDAY.
 
FURTHER TO THE WIND RISK, VERTICAL ASCENT ALONG MONDAY'S COLD FRONT IS EXPECTED TO BE VERY DEEP, LEADING TO A POSSIBILITY OF INTENSE RAINFALL AND SOME ASSOCIATED DAMAGING GUSTS. ACCUMULATIONS OF ABOVE 60MM ARE EXPECTED WIDELY IN THE WEST, SOUTHWEST AND SOUTH WITH PERHAPS HIGHER OVER THE HIGH GROUND OF SCOTLAND, NORTHWEST ENGLAND, WALES AND SOUTHWEST ENGLAND. OWING TO THE WAVING BEHAVIOUR OF THE TRAILING FRONT THROUGH LATE MONDAY, SOME LOWLAND AREAS OF SOUTHERN ENGLAND MAY SEE ACCUMULATIONS OF ABOVE 60MM. FURTHER SHOWERY RAINFALL IS EXPECTED TO ADD TO TOTALS IN THE SOUTHWEST AND SOUTH THROUGH TUESDAY. IN ASSOCIATION WITH FURTHER FRONTOGENESIS AND SHORTWAVING, RAINFALL IMPACTING AREAS OF NORTHERN IRELAND, WESTERN SCOTLAND AND NORTHWEST ENGLAND MAY ALSO ACCUMULATE A FURTHER 40MM WIDELY INTO TUESDAY. GIVEN RECENT RAINFALL AND GROUND SATURATION, WIDESPREAD FLOODING IN THE WARNING AREAS IS VERY LIKELY. UNNECESSARY TRAVEL IS NOT ADVISED DURING PERIODS OF STRONG WINDS. THIS WARNING MAY BE UPDATED. PLEASE MONITOR WEATHER AND TRAVEL INFO AS NECESSARY.

Yep, getting pretty windy there though, 49 MpH at Sevenstones. 

Check out the K2 buoy; that seems to be the closest to the low.

Yup- but how about Station 62095 - M6 - West Coast ?

Pressure 968mb Wind 32mph

Just had a 20 minute walk to the shop and back

Running rivers by the side of the road, a lot of water running down the hill

Drains already struggling

Wind is howling through the telegraph wires

I came back like a drowned rat, even though i wore a coat

 

This beast hasn't even wound up yet. Off to dry off

The low is currently at 964mb right now, dropping extremely rapidly. It looks like it has dropped 8mb in just 2 hours.

 

Max gust here is 46mph already, over 10 miles higher than the strongest gust St Jude gave us, and we aren't even getting the worst of it yet.

This now looks the closest station to the low.

One thing I would like to add is how lucky we are forecast to be, having a 930mb system hitting us and reletively spread out isobars given the strength of the low pressure and jet stream.

This could easily have tightened up alot more on the forecasts and produced some record breaking winds. I hope I don't have to eat my words and the forecast is correct.

Could someone show me where I can see the buoy readings please? Getting windy in Manchester.

Scroll down to the UK met office stations link or the Met Eireann Stations link. I also think you can search by coordinates somewhere.

17mm rain in 4 hours and max gust 47mph so far, flooding could well be the main talking point over Wales today

Isles of Scilly recent gust to 70mph

 

Wow !!

 

Explosive Cyclogenesis: when pressure falls by more than 24mb in 24hrs. Today's storm, it's dropping 60mb in 24hrs!

 

What is today's Low called:

 

Super Explosive Cyclogenesis

 

This storm needs a name... this is historic !!
