Tips for Clearer Skies

[NeutrinoWave]

Ok so Astronomy Weather gives me this forecast

Clarity 4 tending towards 3

Seeing 3 tending towards 2

0mm Rain

0% Low, Medium, High Cloud

Besides High Scores for Clarity and Seeing, 0mm Rain and 0% Low, Medium, High Cloud what else should I be looking for as Optimum Observing Conditions, as I cannot see much out here tonight despite the weather stats.

Whats it like in your area, any luck?

I would like to know how I can get 0% Low, Medium, and High Cloud yet get 41% total cloud.

Seeing is difficult to forecast as there are always local variations due to topography, proximity to heat sources / buildings, and also local microclimates can play their part.

I know humidity is high here. Has been all day with dew remaining on the grass throughout, even though its been sunny. I always find high-dew nights difficult for seeing...and dew

Its clouded over here anyway now

Accurate cloud forecasts for the UK are notoriously difficult to come by

I entered my postcode and it didn't recocnise it

Nor mine and it's not as if I'm in the middle of nowhere (I wish!)

[cantab]

Did you put only the first part? For example "CB2" will give results, while "CB2 1TJ" will give nothing.

Put in your town or city by name

[heathenwoods]

Aha! Yes, I forgot it also gave an option for town. Wish I hadn't though! In summary: bad to rubbish.

more rain more clouds , mayb i should change careers and become an astronaut instead !

If one delves deeper into the forecasts for what they are worth

taking as an example this link

What advice would you take after inferring data from the SFC RH, Surface Relative Humidity

What would be a good stat, that would minimise chance of dew

ie a value below 50%, 25% for SFC RH... and what about the temperature aswell

Any thoughts ...

[LukeSkywatcher]

Not looking good here for the whole week ahead. Total cloud ranges from 50%-100%

If you assume you will be fighting dew from now until March/April you won't be far wrong regardless of the forecast

[DarkerSky]

RH at <80% will give you a good run. 80% to 90% you'll get a few hours. Above 90% you'll be lucky to get an hour before your front optics (secondary for newts) are dewed.

maybe so, but you'd think they could at least get the totals to add up.

[NigelCampbell]

My forecast is equally depressing. Also my plans to move the whole family to the Atacama Desert have not gone down well with my wife.

Thanks DarkerSky, thats useful to know
