Frosty NightsAdded : Saturday at 11:37 Bonfire Night is almost upon us and we often get asked if a cold and frosty Bonfire Night is expected, "just like the ones we used to have". Looking back at the archives show that the Bonfire Night period is not particularly renowned for being cold and frosty, but it probably stands out in most of our minds as we are now at the time of year when night frosts can readily develop and it's more noticeable when we are actually outside in it.
This weekend sees a couple of chilly nights coming up, and it just so happens that they coincide with Bonfire Night so this will do little to dispel the myth!
Here is the synoptic chart from earlier on today:
Frontal systems across many areas are slowly pushing south-eastwards bringing a spell of rain with them and this rain is now pushing away to the southeast with scattered showers following on behind:
Plenty of bright autumn sunshine can be found across Scotland, Northern Ireland and the Republic of Ireland in-between the showers and these clearer conditions will gradually extend to most areas during the rest of today:
However, with those clearer conditions comes a colder Polar Maritime air mass, as reflected by the air mass satellite:
Therefore by the time we get to 9pm this evening that colder air will have spread to most regions with the forecast temperatures looking like this:
Temperatures widely will be back down into single figures and some frost will be forming in the north.
Then for Bonfire Night itself the forecast temperatures are looking like this:
An even colder evening with frost becoming more widespread so wrap up warm if you are heading out to any displays.
Then by Monday morning a widespread frost is expected across many parts of the UK:
Note the milder air over Ireland though, this will be spreading to most areas for a time during the early part of next week as the rather changeable theme continues with Atlantic frontal systems moving in from the west.
Have a fantastic Bonfire Night from all of us at Metcheck but wrap up warm and stay safe.
