They need to mention wind chill more in the forecast...it might be around 8 degrees outside but feels more like 0 degrees with the wind...and how it feels is much more important than the actual temperature when you are out in it...

It would affect an aircraft's actual altitude above obstacles. If flying from high pressure to low, your actual altitude is decreasing despite your altimeter reading the same. If not careful, you could inadvertently fly into an obstacle which would have been well below your altitude when you were in the higher pressure zone. Every hPa is a difference of around 27 feet, so that difference of 26 hPa means you'd be flying 700 ft lower in 999 hPa than you would in 1025 hPa.

The saying goes "Flying from high to low, watch out below".

Unbelievably strong gusts in north Kildare at the moment.

Can’t believe how strong it is against our gable wall

Pretty strong gusts here in Wicklow, had to run out and secure the child's play house as it was starting to move down the garden.
