THE NIGHTS ARE STARTING TO GET LONGER!!!
So says the pessimist, but it is factually correct. The summer solstice was on the 20th June this year.
However, the optimist can truthfully say that there will be more daylight than darkness until the 3rd week in September.
Click on GLOBAL DAYLIGHT MAP in FAVOURITE LINKS & check what goes on. I find it particularly interesting around 10pm, when part of Britain is in daylight & part in darkness. And remember, the places that get many weeks or months of perpetual daylight lose out on being very much colder than we are in Scotland (as we found last year on our journey to North Cape & Spitsbergen)


FORECAST ACCURACY
It takes about an hour each morning to complete PITLOCHRY DAILY WEATHER. About half this time is in researching different sources, mainly BBC, Met Office & Weather Online (all available via links on this site)
On the majority of days, there are some differences in detail between the souces of information.
This site picked up as early as last Sunday, that Thursday would be an unsettled day with rain (the forecast weather charts yet again looked particularly bad).
However, this morning, while BBC 5-day graphics showed moderate rain for almost every hour of the day & into Friday, their Pitlochry rainfall forecast radar map showed it dry until the afternoon on Thursday. Meanwhile the Met Office(Central, Tayside Fife) indicated a dry period between 3pm & 4 pm during the afternoon, with little getting from the south into our area during the morning.
Much of the evidence from radar forecast maps when PDW was being prepared around 0815 pointed to a mainly dry morning,which obviously turned out to be "unhelpful"
The interest in the weather partly comes from its unpredictability. While sunrises, eclipses,transits of Venus & times of high tides are know years in advance, the weather always defies perfect prediction & long may that situation remain!!
