Heavy rain clearing then brighter

Another band of wet weather passed through overnight, this time linked to a quite deep depression over north-west Scotland, certainly for this time of year.  So, more rain to end the month, and whilst skies brightened afterwards, with even some sunshine, temperatures yet again struggled as the dominant weather pattern for the last few weeks continues.  There are signs of change in the forecast, thankfully - temperatures are set to rise and the sun should return by Wednesday next week.

Cloudy with occasional sun

Rain overnight cleared before breakfast, to leave a dry day with occasional glimpses of the sun in a sky generally filled with cumulus cloud.  Still a piercing wind from the northwest, so outdoor coats are still required as temperatures once again struggled.

Heavy morning rain then improving

Heavy rain this morning for the rush hour, and grey skies proliferated throughout the morning with further showers from time to time.  The sun managed to find one or two gaps in the cloud by dinner time though, and the gradual improvement continued during the afternoon, with just one or two showers persisting until tea time.  Still cold and breezy and very unseasonable for late May.

Cloud again and some heavy showers

Cloudy this morning, and whilst the sun made some fleeting appearances throughout the day, gradually rain moved in, including some heavy bursts just at rush hour.

Still cold, with no sign in the forecast that it'll change any time soon.

By evening, the showers died but there was still an active sky, sunshine lighting the clouds creating a fiery spectacle.

Wet and miserable, slow to clear

When Bob Geldof wrote about not liking Mondays, he was probably thinking about a similar Monday morning to today.  Rain, not in any hurry to move on, that lasted a good part of the morning, and even after it stopped, the skies didn't make much effort to improve.  At least not until mid afternoon, when gradually the sun began to make an appearance, in between heavy shower clouds that brought hail as well as rain.  Despite all this, after tea the rain stayed away and we had a reasonably pleasant end to the day.  Temperatures all day were again nothing to write home about though - it's about time some warmer weather arrived.

Chilly and cloudy

Apart from the lightest of drizzle for a short spell over lunchtime, today was once again dry, but again the wind, this steady run of north-westerlies we've experienced recently, pegged back the temperatures well below the seasonal average.  It was actually warmer on the first of January (max 12.6°C) than it was today!  There was also much more cloud than yesterday, so we didn't have the sun to lift things at all.

Some sun but still really cool

Some rain overnight, then variable amounts of cloud for most of the day.  But there was some sun too, and gradually the sun won over, ensuring the day ended bright and cheerful with blue skies.  Despite the sunshine, there was a stiff north-westerly breeze, ensuring temperatures remain disappointing - by mid-May we really should be feeling something a bit warmer.

A pleasant sunny day

Originally we weren't holding much hope out for Friday as all week the forecast said a band of rain would be moving through.  By yesterday this had changed - rain was expected during the afternoon now - but the reality was still better.  A sunny morning with plenty of sunshine, clouding over for a time before more sun in the afternoon.  Temperatures not overly warm but better than of late.  A little drizzle by later in the evening.

Dry, fine with some sun yet still cool

A dry day and some regular spells of sunshine, cloud thickening and breaking regularly all day.  There has been a low pressure system moving south east from Ireland, bringing wind and rain to Wales, then the midlands and the south of England, but for once it didn't trouble us - the northern edge of this system stayed just to the south of Oakdale Weather Station.

Rain clearing, then sunshine for a time

Rain clearing, then sunshine for a time sums it up really.  It wasn't the greatest rush hour journey this morning, with rain on and off throughout the journey to work.  But by mid-morning the clouds lifted and we saw some good spells of sunshine and warmer temperatures than we've seen for a while.  The clouds were never all that far away and gradually they won the competition with the sun, but we did end the day without further rain.

Trying its best...

Again the forecasted weather didn't quite happen today - a low pressure system was moving northeast over Ireland into Scotland, taking a large area of rain with it, and it was expected that we would perhaps catch the back edge for a short time before it moved away and sunshine took over.  In the event, whilst we didn't see much in the way of rain, it remained annoyingly cloudy with some hazy sunshine at times.  Still not especially warm, but the odd glimpse of a watery sun did add a couple of degrees to the thermometer.
