The river was filled in with snow but you weren't allowed to hike far off road markings due to foot and mouth signs everywhere(they weren't quite buried unfortunately!).
It was indeed during the F&M outbreak!
But I doubt that cause the snow

Then there was the 8" fall in Dublin on 28th February 2001; it remained on the ground for another 8 days in cloudless skies and near freezing temps till about the 7th March.
Not many people remember this!
I don't remember it sadly. If it was a decent snowfall I would remember it. I think I had less than 5 snow days off school.0 -

I used to joke about the Bray Snow Shield but with what I have learned here it really exists, just not in the Starship Enterprise form I envisaged
Barring major Frontal battles like '82 and '87, the long land track and Wicklow and Dublin Mountains that wrap around Bray deal with anything coming from the NW,W,SW & S. Long land track deals with anything from the North. Being right in the middle of the East coast means that the Eastern counties of ulster mean not enough of a sea track and a resultant snow shadow with Bray at the southerly extremity of the shadow for NNE. Again Brays position in the middle of the east coast puts us within the Isle of Man shadow for most North Easterlies or anything close to one. Picture the wind coming from behind the IOM. Visualise the shadow cast up and down the east coast of Ireland as the wind changes direction. Because Bray is in the middle of the East coast were are usually within some part of the shadow no matter what part of the east coast the shadow is on. We might be smack bang in the middle for a pure North Easterly. If Meath/Dublin is in the shadow Bray is within the southern boundaries of it and the rest of Wicklow/Wexford get the snow. If Wicklow/Wexford is in the IOM shadow, Bray is usually within the Northern boundaries of the shadow and Dublin/Meath get the snow. If its a true easterly we are in the Anglesey/Wales shadow.
Basically, if the wind is not coming from the direction of Cumbria/Blackpool where there is enough of a sea track then Bray gets sweet fanny adams!!
And even when it is coming from the right direction for us?? We ended up between streamers more often than not. All Brays snow for that whole month last year came from basically 2 or 3 heavy 90 minute showers
With regard to the 2001 event. I think Bray got about an inch out of that 0 -
Lived in Bray for years so I know what you mean!
The shield works for rain (and clouds) as well so not all bad
(Any weather stations in Bray? - the rainfall there must be the lowest in Ireland and the sunshine the highest)
I remember back in the day before the M11 the traffic from Bray to Dub was atrocious and commuters like me-self did a rat-run through The Scalp, Stepaside and so forth - there might be a bone dry hard frost in Bray and it always seemed to be snowy in Sandyford.
So I moved
(Hint hint)
(I did love Bray though, great place to live and one of the most under-rated spots in the GDA)0 -

Our very own trogdor has a station there. http://www.brayweather.com/
BTW, thanks for posting up all the photos of past snow events! 0 -

If I'm reading Trog's stats correctly (which I'm probably not) then Bray had about 580 mm in 2011
That is dry - and what I'd have expected 0 -

I wondered who ran BrayWeather! I have been addicted to that site since I moved here, and have been using it recently to "calibrate" my weather station that I got for Crimbo. trogdor, I miss your forecasts!
And I agree about the frustrating snow shield!!! :mad:0 -

High pressure builds over the weekend and next week as the jet stream shifts north and slows down.
Light rain or drizzle will affect the north and west at times though as fronts zip by toward Scandanavia
Hopefully it will be nice and dry for the rest of us !
Sick of looking at rain !0 -

Must be a resolution issue on met.ie radar because the drizzle showing up ok on the Weatheronline radar:

Not an issue with the radar as such, issues with the humans rather . If you remember the uproar about the change of radar imagery on last years upgrade, some people were giving out that it was showing rain over them when there wasn't any. This was due to evaporation of rainfall in the last 500m, which happens regularly in summer.
To counteract this, I suspect, Met Eireann dropped all echoes returning below a measurement of 0.2mm/hr from the radar to suit the customer. Now, that we are in winter, the drizzle is not being detected - or so we think!
In reality, it is being detected, but the computer that renders the imagery for the web drops the colour coding to keep us happy as per order in the summer.
The other radars just include a colour for the 0.1mm/hr rate whereas our radar doesn't. In the summer people will probably be giving out about the other radars showing rain where there isn't any and Met Eireanns will be fine...
Geddit? :pac:0 -

Well, Sponge, we have the opposite problem here!
The ME radar often shows rain when in fact there is none falling 0 -

A more likely reason is all the Wireless equipment broadcasting up in Sandyford as I explained here in this forum last year when people noticed interference on the Met Radars.
http://www.wi-fi.org/files/FCC_Memorandum_on_UNII_Device_Operation_2010_07_27-M.pdfThe Federal Communications Commission (FCC), the National Telecommunications and
Information Administration (NTIA) and the Federal Aviation Administration (FAA) have
been investigating interference caused to Terminal Doppler Weather Radar (TDWR)
systems operating in the 5600-5650 MHz band. TDWRs are used to detect wind shear
and other weather conditions near airports. The interference manifests itself as a strobe
line or lines on the radar display. While the radar continues to be usable, such
interference is unacceptable and must be eliminated. More importantly, if the
interference were to become severe, there may be a potential for missed alerts or false
alarms.
We have found that the interference at each location has generally been caused by a few
fixed wireless transmitters used by wireless internet service providers (WISPs) and
operating outdoors in the vicinity of airports at high elevations that are line-of-sight to the
TDWR installations (5 GHz outdoor network equipment). In most instances, the
interference is caused by operations in the same frequency band as TDWRs, but there are
some instances where the interference is caused by adjacent band emissions.
(yadda)
In other instances, equipment that met the FCC’s certification standards nonetheless
caused interference, due to a variety of factors such as: the configuration of the
transmitter, its height and azimuth relative to the TDWR, and the device’s failure to
detect and avoid the radar signal. In such cases, the FCC’s rules still require the
elimination of the interference and the FCC has taken appropriate action in those cases.
So as long as Broadband in Ireland is crap you will always have a raincloud in Sandyford Bill! 0 -
