There's something markedly different. This is the second day in a row we've had completely clear skys and sun for most of the day. At 5.00pm as night was falling there was a clear sky, and as it darkened clouds appeared. Within 20 minutes we'd complete overcast, heavy rain and winds...exactly like last night, and many nights before. It seems to me that things are being driven by falling temperature with the onset of night, rather than by the usual pressure systems. Some of you people who know about dynamic weather systems may be able to correct me on that, and I'd like you to. I haven't seen a protracted period of bad weather at night for many, many years...we've had two or maybe three clear nights in getting on for two months, with no sign of a let-up. If this is what global heating means, I'm moving.

I know what you mean - I must have been no more than a couple of minutes away from seeing the comet this evening - I had already got Venus in the bins - when this big black cloud came over. I decided to leave work and go over the hill where it was tipping with rain, except the sky cleared by the time I got to Templepatrick - just too late to see the comet!
It's not Global Warming, its personal!

I dunno to be honest... I'had noticed the days being clear and just as you want to go out at twilight, the clouds roll in from a general western direction. I think last night, there was a warm front approaching, but we didn't get the usual sequence of cloud - high cirrus thickening to medium level cloud and then the lower, rainy stuff at that particular time. I just saw a long line of cumulus to the west stretching roughly north-south, obliterating any chance of seeing McNaught. The warm front and the arrival of a new low pressure system happened much later on, according to the charts anyway. And the same thing happened the night before. I was wondering too if the loss of heat from a relatively warm land around sundown was causing this but you'd think that fog would form instead, given the remainder of the sky was clear. Why would low level cloud form only in the west, in a fairly local area? Having read some rather complicated meteorological stuff on UKWW there seemed to be some complexities with the last couple of lows (and a High over France) and I reckon our peculiar experiences have had something to do with this rather than local ground/air temperature. You should read that stuff - I never realised you could have upper weather systems as well as the stuff you see on the usual synoptic charts. Wish I'd become a meteorologist after all, then I could understand this stuff! But I ain't an expert ;D Where's Mark, Mr Weatherman???

Umm, I'm no expert but I remember reading there was some sort of inversion last year in the Atlantic that will cause us to have more rain and wind - no joke. It inverts every 3 years or something, I dunno - would need to look it up.

Thanks for the links Mark - interesting topic. Very nice of Mother Nature to provide us with more wind and rain, just in case we don't already have enough!!
