Incoming Cold Spell Discussion - 28/01/2019 - 2/04/2019

Recommended Posts

For all your non-model upcoming cold spell discussion that isn't strictly regional based. 

 

Where's Tuesday's low going to affect?

 

Will it snow in my back yard on Wednesday?

 

Where are the latest met office weather warnings for?

 

Is Thursday's low weakening and does that stop my house being buried?

 

Is dry snow better than wet snow?

 

Will it rain?

I think powdery snow and dry snow is the same thing.

Knowing this place, there's some who could find a way to separate the two 😛

Met Office snow and Ice warnings updated this morning. Matrix shows SE snow still low prob. This morning's front page article https://www.netweather.tv/weather-forecasts/news/9378-uk-weather-snow-is-likely-this-week-stay-tuned-much-colder-air-on-tuesday

Hi Jo,

Can you think of a reason why Northern Ireland is missing from this warning? Parts of Tyrone and Derry will be most exposed to the snow showers pushing in from the North West tomorrow and the Euro4 snow forecast is fairly bullish on NI snowfall.

Thanks in advance.

The same reason they seem to be underestimating the potential snowfall for the North West imho, there focusing entirely on snowfall depths as the low pushes through and not very much on the shower's associated.

I suppose looking at the ingredients for a warning. Timing -yes Tues am rush. Population centre- not really. Snow amounts-not widespread, Scottish bit is for higher ground and Glasgow/M8. They may still issue one, but perhaps it is covered by the overall wintry story? Don't know. WBFL in Euro4 can be too low in these situations but only tomorrow will tell.

The slider on December 10th 2017 brought proper snow to about 5 miles south of me, but just a dusting over Belper. This is looking similar. My guess is the same will happen again. Northern snow line will be around Derby.

Of course I hope this is not true.

100,000 people live in Derry. It's the second largest city in Northern Ireland.

 

Using their chart I'd place that as a yellow - low likelihood - high impact.

Certainly looks good for you guys in the North West, for us in County Down, just hoping that some showers manage to get East of Lough Neagh.

Does that show the band as being mostly rain (blue) with just the purple areas as snow? 

Forgive the noob question!

Yes, look at the key chart underneath the picture. Pink = snow and Blue = rain (this isn't the same for all charts so always look for keys in images posted 🙂 )

afternoon all, well here we can look forward to rain and maybe a bit of sleet at times, thats what you get for being at sea level i guess, on the plus side it certainly looks like a few lucky peeps are going to get something wintry, all down to timing and a bit of luck though

I think it all depends how slow this front is - I can see anything after 6pm being wintry in nature, depending on Intensity may get a covering in quite a few places 🙂

Most of the precip charts seem to have our region in a sweet spot for Thursday, plenty of time for that to change of course but it's looking alright for now

Take precip charts with a pinch of salt, because I am sure it'll be different on the day.
